Essay Sample on Commissioning and Final Acceptance of Projects

Essay Sample on Commissioning and Final Acceptance of Projects Introduction This paper highlights the ways in which to handle conflict between contractors and clients. In this sample, the contractor was tasked with the construction of a building. However, during the commissioning process of the building, an inspection report by a building inspector and engineer revealed that there were minor defects in the HVAC system. Therefore, as the agent representing my client, I am tasked with dealing with both the client and the contractor so as to come up with an amicable solution with regards to the problem at hand. Commissioning Process The commissioning process was done by a professional building inspector and engineer as stipulated by the contract between the civil engineer and the representatives of the client. The contractor was to deliver the building as fully operational. The same company was to be paid a lump sum that would cater for all costs. This would include the hiring of another electrical firm to handle all electrical installations. The HVAC system was part of the electrical system. However, the main contractor wanted to be paid an extra sum to repair the HVAC system but the client refused to do so stating that those were not the terms of agreement as stipulated by their contract. Therefore, I acted as the mediator in this case. â€Å"The primary benefit of mediation is risk and cost control. Because the parties arrive at the solution, the disputants maintain control of the entire process.† (Kelsey 2010: 1). Communicating With The Client The client was informed of the HVAC defects and the position of the main contractor. The client declined to add any more funds towards the project. The client claimed that the relevant clause with regards to the conflict mentioned was clearly stipulated in the contract. The client further claimed that the contractor had accepted all the terms of the contract without any question. This was also the case as all the other bidders of the contractor. The client therefore felt that the contractor was going against the terms of agreement. It was assumed that the bid would take care of any contingency with relation to extra costs that the contractor would have to incur. Communicating With The Contractor The contractor was informed of the position that the client had taken with regards to the defects in the HVAC system. The contractor accepted that they had failed to raise this matter during the bid clarification meetings. This is because such implications had not been noticed. However, they claimed that the defect was not caused by them and that they had done their civil work perfectly. They claimed that the additional costs should not be levied on them but on the electrical firm that had installed the HVAC system. Effect Of The Observed Defects On further scrutiny of the contract agreement, it was found out that the contractor had a weak case to prove. This is because the client made an agreement with the civil company and not the electrical firm. Therefore any dispute was to be handled between the electrical firm and the civil firm. Since the commissioning was underway, the client was not to suffer the consequences of this conflict. An amicable solution was devised and the HVAC system was to be repaired and the conflict issues be sorted out later. This meant that the final payment of the contractor was not changed and that the issuance of the final certificate was done in time. Academic Reference Describing The Processes In Closing Stages Of Projects The closing stage of projects involves a â€Å"formal acceptance of the project and the ending thereof.† (Harrison, 2004: 34). Documenting the lessons learnt and file archiving are some of the administrative activities involved. The closing phase involves: Contract close: settle and complete each contract. Each contract that is applicable to the given project should be closed. Project close: all the activities in each of the process groups should be finalized for the formality of closing the given project. An example relevant to this case is given by a case study by Whitticks (2005) titled ‘Direct and Consequential Costs’. In the final phase, the following statement resolves the dispute between the contractor and the client â€Å"Such penalty for delay shall be recoverable from Contractor by any means available to Company under the terms of this Contract or at law.† (Whitticks, 2005: 230) Conclusion â€Å"Every party mentioned in a construction contract is responsible to follow the terms agreed to in the contract† (Rothstein 2013: 1). Before accepting terms of any contact, thorough scrutiny should be done and any ambiguous statement is brought forward for clarification. This will take care of any possible scenario that may occur during the project implementation. â€Å"Honesty and candor between the owner and the contractor is necessary for progressive construction management.† (Levin, 1998: 7).

How to Write What Is Truth Philosophy Essay

How to Write What Is Truth Philosophy Essay What Is Truth? General guidelines for composing a philosophy essay on ‘What is Truth’ Tips on how to start writing How to write an outline How to write a thesis for a philosophy essay on ‘What is Truth’ How to write an introduction Tips on how to write an introduction and thesis How to write body paragraphs Tips on body writing How to finish a philosophy essay on ‘What is Truth’ Tips on conclusion writing Tips on revision What is Truth? (Philosophy essay sample) General guidelines for composing a philosophy essay on ‘What is Truth’ To write a perfect essay, begin with a clear statement of the given inquiry (in this case, on ‘What Is Truth?). The inquiry should be stated. However, it is wise to give a reasonable statement in the first and second paragraph on how you intend on addressing the question and which approach of the question you intend to take. Secondly, state your position and defend your answer. Defend it with reason, arguments, and relevant information. Lastly, identify and formulate the strongest potential objection(s) showing its strength to refute your position. Tips on how to start writing Start by outlining how you want to argue. Your philosophy essay should demonstrate a logical progression of ideas making it easy for the reader to follow. Once your outline is determined, select specific words that will transmit your intentions to the reader. Substantiate your claims whenever you think your critics will not grant them. And when paraphrasing or quoting, always give credit. Indicate your indebtedness for general ideas, specific lines of argument and particular words. How to write an outline It can be challenging to start a paper with an outline primarily. Nonetheless, once one has written a draft, it is relatively easy to go back and outline it. An overview gives the writer a sketch of the paper and aids in work organization. Below is how the outline can be organized. I. Introduction (Include the problem statement and approachesb to be taken) II. Arguments/Reasons Argument/Reason 1 Support your point Argument/Reason 2 Support your point Argument/Reason 3 Support your point III. Strongest challenge(s) to your position IV. Arguments/Reasons showing why the strongest challenge does not make your reason incorrect V. Conclusion How to write a thesis for a philosophy essay on ‘What is Truth’ The sentence or short paragraph that stresses your stance on a particular issue, particularly, the position you will argue for in your paper is the thesis statement. To write a thesis statement, one needs to determine their position. This is done by thoroughly reviewing relevant course materials, evaluating and analyzing arguments on both sides and ultimately developing your take on the issue. It is exigent that you describe your thesis before you continue writing. This is because your thesis guides you throughout the entire writing process- everything you write should somehow contribute to its defense. How to write an introduction The introductory paragraph is the most important paragraph in your essay. It ought to be fifty words long or five sentences minimum. An introductory paragraph is written by first introducing the topic. Second, grab the reader’s attention (a hook). And third, have a solid thesis statement which holds three points you will discuss. Tips on how to write an introduction and thesis When writing an introduction, you need to: Say something unusual Do not repeat the title Ensure the introduction is brief Cite thoroughly but not excessively Refer to a problem or concern your reader might have How to write body paragraphs Naturally, body paragraphs develop the paper’s main idea in a series of paragraphs. To write a body paragraph, the writer’s chosen topic must be explained, described and argued. All main ideas written down in the outline make the body paragraph. Bear in mind; body paragraphs support, prove, and explain your paper’s thesis statement or argumentative claim. Tips on body writing Create an outline (to organize your ideas and maintain your focus on the central topic) Organize your paper so that each paragraph groups together similar ideas and doesn’t mix unrelated topics Conduct research Remember keywords Explain your argument’s significance How to finish a philosophy essay on ‘What is Truth’ One concludes an essay by summarizing their argument and restating their thesis. In the conclusion section, make an effort in convincing the reader that the thesis is established and a cogent argument is offered in its defense. Alternatively put, one finishes a paper by restating the main idea along with the thesis statement, summarizing the essay’s sub-points, and leaving the reader with an interesting final impression. Tips on conclusion writing To conclude your essay correctly, follow the tips below. Summarize the essay’s key points Ask an exasperating question Utilize quotations Call for some action Conclude with a caution Generalize (contrast with different circumstances) Suggest consequences or results Tips on revision Examine your essay’s balance Check your paper’s organization Check your facts (are they all accurate) Check your conclusion (does your conclusion tie the paper together) Utilize spell-check to correct errors What is Truth? (Philosophy Essay Sample) I. Introduction ‘Truth’ has many meanings, yet the most widely recognized definitions allude to a position of being in observance of reality or facts. There exist different paradigms, rules and criteria by which individuals’ critic the truth a statement professes to affirm. The issue is how individuals can be guaranteed that they are in observance of realities or facts when every human mind manipulates, falsifies and perceives what it chooses to interpret see, or hear. Possibly an enhanced description of truth can be an accord of a conclusion by numerous people regarding the realities and facts in question. II. Discussion Truth is unique to an individual. For me, feeling hungry is more truthful than 10+10=20. No truth can objectively be confirmed – factual or otherwise – plus the yardsticks by which humans classify truths are consistently subjective and relative. What people deem as true, whether in art, morality, or science, varies with the existing intellectual current, and is consequently established by social, technological, and cultural yardsticks of that given epoch. Ultimately, humankind is both unique and fallible, and whatever information we uncover, factual or not is revealed by humanity’s’, finite, predetermined mind. The nearest truth is one where we have reached consent because of our social conditioning and related educations. For this reason, truths frequently don’t exchange among cultures. This idea is closely linked to ‘conceptual relativism’ – a far-reaching progression of Kant’s knowledge which asserts while studying a language we discover new ways regarding worldly interpretation, and hence, speaking another language inhabits a separate prejudiced world. I believe our characterization of truth should be increasingly versatile than Descartes, Plato or other philosophers. To me, the pragmatic theory of truth hits home. It affirms that truth is whatever is fitting; if another new idea is more fitting, it becomes truer. This theory is one Nietzsche almost accepted. There being no objective truth frees us to create our truths. In citation to Sartre’s existentialism, individuals aren’t confined by objectivity; instead, the absences of immutable, unending, truths enable us to formulate ‘truth’ for ourselves. I believe ‘Truth’ is personal. Your truth and my truth share no basic pertinence to each other. Since truth is personal and cognitive, it does play a more decisive and unique position in giving life significance; I am liberated to select my truths, and thus, I frame my life. Without cognitive truth, self-determination is non-existent. III. Conclusion So, to the apparent comprehension that the phrase â€Å"truth† is hugely ambiguous, great care should be taken to eliminate ambiguity in arguments concerning truth.

Learning activities Essay Example | Topics and Well Written Essays - 1000 words

Learning activities - Essay Example The Americans public displays of affection are seen as liberated and rude in front of elders of Asian countries like the Philippines. It is in this way that false assumptions are made of cultural differences. While racism seeks to rationally and consciously oust different ethnicities, ethnocentrism is created by enculturation (Patterson 2005). A great disparity occurs because of the presence of ethnocentrism in the minds of individuals. With it comes improper deliverance of health care facilities to members of different races and ethnicities. Health workers, community members and policies are all affected by ethnocentrism which prevents individuals from getting the full benefits of a health care program. Despite all of this, there have been universal standards of right and wrong that are introduced and prevalent in the world today. The ideas of a superior white race during America's colonial times have been replaced with equal systems being created for whites and blacks alike. Thus, with time come change and a greater acceptance of different cultures. 2. There are certain health care jobs that each federal and state government is responsible for providing to the citizens of their country. This includes basic ideas like protecting the health and safety of every individual. The physical and mental health of each citizen has to be recognized and acknowledged through providence of proper food and nutrition along with controlling of diseases and providing for the elderly. But it also includes the measures that must be taken to protect the health of citizens during disasters. This includes providing and realizing the basic health care needs of each individual in a disaster hit area and providing relief medicine and goods accordingly. 3. Don't know 4. Don't know 5. Medicare refers to a social insurance program that is set up by the United States government to provide for the coverage of health insurance to any citizen over the age of sixty five or those who meet the special criteria (Medicare Rights Centre). Operating under a single fund, the doctors and expenses of this insurance program are all funded by the government itself. 6. Medicare is a perfect example of a health policy provided for by a single payer: in this case the government. Thus, living up to the ideals of social liberalism, Medicare provides equally for the patients who fit the required needs. 7. The presence of health care provided according to income is ample proof of an economic liberalism that exists in the United States Module 5 Allied health professionals provide a varied and diverse number of services. The education sought by each of these doctors, the degree of autonomy they have been allowed by the medical establishment that employs them and the regulations that have been set out to control their practices are all varied and different from professional to professional. However, there are a number of similarities between them. Emerging from the same history and evolutionary path, the creation of the autonomy is distinctly similar. Cost effective strategies have forced tremendous

Push and pull factors in Syrian migration Essay Example | Topics and Well Written Essays - 750 words

Push and pull factors in Syrian migration - Essay Example (Mooney, 2014). Mostly, people flee in entire families in order to save their children. The flow of refugees from Syria affects many other states including both the immediate neighbors and the more distanced countries, because the refugees looking for shelter, employment and safety produce considerable impact on their social welfare policy and economy. With the outbreak of the war, forced migration began including people seeking asylum abroad and internally displaced citizens. The scale is rather disturbing, as nearly a half of the entire Syrian population is reported to have migrated; and the numbers of refugees has been persistently growing since 2011. Presently, the number of the emigrants registered in other countries reaches 3,810,574 people, according to the reports of the UN Refugee Agency (UNHCR, 2015); whereas the number of internally displaced citizens is estimated 6.5 million (Nebehay, 2014). It is necessary to mention that not all Syrians have been able to cross the border in order to migrate to other countries: many of them are reported to have difficulties in crossing the border. It is especially relevant for Palestinian refugees living in Syria, who are often deported from the neighboring countries (e.g. Jordan) back to the warring country (Mooney, 2014). However, the flow of the internally displaced doesn’t seize, because people’s lives are endangered both by governmental military forces and â€Å"non-state armed groups† (The Independent International Commission of Inquiry for the Syrian Arab Republic, 2014). The most frequent destinations of the forced migration are the immediate neighbors, Jordan, Turkey, Iraq, Lebanon; other countries to give refuge to Syrians are Egypt, the United States, North African countries and members of the European Union. Particularly, Jordan remains among the most favorable hosting countries for a range of reasons. The influx of

Criminal justice Essay Example | Topics and Well Written Essays - 500 words - 3

Criminal justice - Essay Example Nevertheless, unexpectedly, every single one of these studies was carried out within the period of the Miranda resolution, and none have been repeated afterward. Hence, the entire literature on the impact of the Miranda Act on individuals and law enforcement personnel thus far originates from studies that were carried out during the early years of Miranda (Cassell & Fowles, 1998). Because the more enduring effect of a court resolution is more relevant to academics than its immediate impacts, as expressed by Leo (1996), it is astonishing that no academic has investigated the effect of the Miranda Act in almost three decades. The Miranda Act has been the most contentious and the most condemned case of the Supreme Court in the United States criminal justice (Fridell, 2006). Even though nobody has methodically studied the continuing impacts of Miranda on collective awareness, court cases, or law enforcement methods and behavior, the subject matter of Miranda’s effect is still a ro ot of contention among academics and practitioners (Leo, 1996). Despite the unending debate between liberal and conservative scholars of the Miranda Act, law enforcement personnel have effectively adjusted to the provision of Miranda of ‘pre-interrogation constitutional warnings’ (Leo, 1996, 628) in recent years.

Exploring The Chemistry Of Adhesives Chemistry Essay

Exploring The Chemistry Of Adhesives Chemistry Essay An adhesive is a substance that sticks to the surface of an object such that two surfaces become bonded. A typical home improvement store carries many different adhesives for many different applications..The interaction of molecules is known as intermolecular bonding, or secondary bonding. Primary bonding, also known as intramolecular bonding, is the interaction of atoms within a molecule and includes covalent and polar covalent bonding. Secondary bonding includes dipole-dipole bonding (the interaction of molecules that have a permanent net dipole moment) and hydrogen bonding (an interaction that occurs when a hydrogen atom is bonded to an N, O, or F atom in a molecule). Adhesives cure when the small resin molecules join together to form extremely large molecules known as polymers. For example, one of Some adhesives, such as this wood adhesive, are used only with specific substrates because of the cure time needed to allow for good bonding. The simplest polymer is polyethylene. The mer (basic building block of the polymer) is ethylene, H2 C=CH2. The addition of an initiator (R) causes the formation of the radical RCH2 CH2 . A radical is a species that has an unpaired electron and is very reactive because it seeks the source of electrons. This radical will attach the ethylene mer (the double bond in ethylene is rich in electrons) to start a chain reaction that continues until very large polymer molecules form. This and other forms of polymerization processes are the basis for the formulation of polymers. This process is known as curing when dealing with adhesives. Two criteria must be met in order for a molecule to possess a permanent net dipole moment: (1) an unequal sharing of electrons within the molecule such that one or more intramolecular bonds has a partial positive end and a partial negative end, and (2) a geometry such that the vector sum of the individual dipole moments does not equal zero. The ability of an atom within a molecule to attract electrons is known as electronegativity, a concept proposed by Linus Pauling who established a table of relative electronegativities. In Paulings table, fluorine is the most electronegative element and is given the value of 4.0. The greater the difference in electronegativity between two atoms within a molecule, the larger is the dipole moment in that bond. Because the bond between two atoms having unequal electronegativities has a partial positive end and a partial negative end, it is said to be a polar bond. If the geometry of the molecule is such that the vector sum of all of the dipole moments does not equal zero, then the molecule is polar. The electronegativities for carbon and oxygen are 2.5 and 3.5, respectively; therefore, the carbon-oxygen bond is a polar bond. A carbon dioxide molecule has two carbon-oxygen bonds; however, its geometry is such that the vector sum of the two dipole moments equals zero, and thus carbon dioxide is a nonpolar molecule. The electronegativity of hydrogen is 2.1, thus a hydrogen-oxygen bond would be polar. A water molecule has two hydrogen-oxygen bonds. The geometry of a water molecule (the H-O-H bond angle is 104.5 °) is nonsymmetrical, hence the vector sum of the dipole moments is not equal to zero and water is a polar molecule. Polar molecules will attract other polar molecules because of their net dipole moments. Water molecules, however, have an additional attraction for one another, based on hydrogen bonding. This attraction is so strong that, although water is a small molecule and small molecules tend to be gases, water is a liquid at room temperature. This aspect of the chemistry of water demonstrates that hydrogen bonding is a relatively strong force that can hold molecules together. Two surfaces there must be several types of interaction between the adhesive and both substrates. The first type of interaction is that the adhesive must wet the substrate, that the adhesive must spread itself out into a film that covers the substrate surface. In order for this to happen, the adhesive must have a low enough viscosity so that it will flow. Viscosity is the resistance of a liquid to flow. Water has a low viscosity whereas honey has a high viscosity. Because viscosity is temperature dependent, the application of a cold adhesive to a substrate, or the application of an adhesive to a cold substrate, may result in poor wetting. Another factor that affects wetting is the relative strengths of cohesive forces, and those of adhesive forces. If the cohesive forces among adhesive molecules are weaker than the adhesive forces between the adhesive molecules and the substrate surface, then the adhesive molecules will spread out over the substrate and wet its surface. An adhesive t hat has a relatively low viscosity and is able to wet the substrate surface will flow into any tiny cracks or pores on the substrate surface. Mechanical bonding is one of several ways that an adhesive bonds substrates. All surfaces, except those that are highly polished, have pores. If the adhesive flows into these pores and then polymerizes, a mechanical bond is formed. The interactions of adhesive molecules with substrates are so critical, it makes sense that some adhesives would be more appropriate for a specific substrate than others. Adhesives are designed for specific applications. For example, adhesives known as super glues (cyanoacrylates) are useful around the home in the bonding of common substrates (e.g., dishes, toys, etc.), which can take place in a matter of seconds. Cyanocrylates tend to be brittle thus they are vulnerable to impact and dramatic changes in temperature. To reduce these shortcomings, small amounts of finely ground rubber has been used as filler. The rubber introduces flexibility thus reducing brittleness. In addition, cyanocrylates are attacked by polar solvents. Polar solvents will weaken cured cyanocrylate bonds over time. Therefore, applications involving water, alcohols, or other polar solvents should be avoided. Cyanoacrylates are not appropriate for the bonding of the steel parts of an automobile, because of the environments that the car will be exposed to. Those environments include such things as rain, variations in temperature, exposure to solvents (such as gasoline, oil, and windshield washer solution), ozone, acid rain, salt spray, and ultraviolet light from the Sun. Another example of a special adhesive would be the one used to attach a new rearview mirror in an automobile. Because the cured adhesive in this case will be exposed to wide variations in temperature and to an extremely large amount of ultraviolet light from the Sun for prolonged periods of time, an adhesive formulated specifically for these conditions should be used. Finally, the strength and permanence of the bond formed between adhesive and substrate must be considered when one is selecting an adhesive. Most of the time it is desirable to have maximum strength and permanence; the very common Post-it note, however, is a counterexample. Its adhesive is neither strong nor permanent. Lists of some common types of adhesives and their uses. Because of the different possible substrates and combinations of substrates, and because adhesives are subject to such a range of environmental conditions, it is no wonder that there are so many types of adhesives on the market. However, if one has some knowledge of how adhesives bond to substrates and the types of substrates being bonded, the task of selecting adhesives will not be overwhelming. TYPES OF ADHESIVE NATURAL ADHESIVE Animal glue Casein glue Blood albumen glue Starch and dextrin Natural gums SYNTHETIC ADHESIVE Contact cements Structural adhesives Hot-melt adhesives Pressure-sensitive adhesives Ultraviolet-cured adhesives NATURAL ADHESIVE: Natural adhesives are primarily of animal or vegetable origin. Though the demand for natural products has declined since the mid-20th century, certain of them continue to be used with wood and paper products, particularly in corrugated board, envelopes, bottle labels, book bindings, cartons, furniture, and laminated film and foils. In addition, owing to various environmental regulations, natural adhesives derived from renewable resources are receiving renewed attention. ANIMAL GLUE The term animal glue usually is confined to glues prepared from mammalian collagen, the principal protein constituent of skin, bone, and muscle. When treated with acids, alkalies, or hot water, the normally insoluble collagen slowly becomes soluble. If the original protein is pure and the conversion process is mild, the high-molecular-weight product is called gelatin and may be used for food or photographic products. The lower-molecular-weight material produced by more vigorous processing is normally less pure and darker in colour and is called animal glue. CASEIN GLUE This product is made by dissolving casein, a protein obtained from milk, in an aqueous alkaline solvent. The degree and type of alkali influences product behaviour. In wood bonding, casein glues generally are superior to true animal glues in moisture resistance and aging characteristics. Casein also is used to improve the adhering characteristics of paints and coatings. BLOOD ALBUMEN GLUE Glue of this type is made from serum albumen, a blood component obtainable from either fresh animal blood or dried soluble blood powder to which water has been added. Addition of alkali to albumen-water mixtures improves adhesive properties. A considerable quantity of glue products from blood is used in the plywood industry. STARCH AND DEXTRIN Starch and dextrin are extracted from corn, wheat, potatoes, or rice. They constitute the principal types of vegetable adhesives, which are soluble or dispersible in water and are obtained from plant sources throughout the world. Starch and dextrin glues are used in corrugated board and packaging and as a wallpaper adhesive. NATURAL GUMS Substances known as natural gums, which are extracted from their natural sources, also are used as adhesives. Agar, a marine-plant colloid is extracted by hot water and subsequently frozen for purification. Algin is obtained by digesting seaweed in alkali and precipitating either the calcium salt or alginic acid. Gum arabic is harvested from acacia trees that are artificially wounded to cause the gum to exude. Another exudate is natural rubber latex, which is harvested from Hevea trees. Most gums are used chiefly in water-remoistenable products. SYNTHETIC ADHESIVE:- Although natural adhesives are less expensive to produce, most important adhesives are synthetic. Adhesives based on synthetic resins and rubbers excel in versatility and performance. Synthetics can be produced in a constant supply and at constantly uniform properties. In addition, they can be modified in many ways and are often combined to obtain the best characteristics for a particular application. The polymers used in synthetic adhesives fall into two general categories-thermoplastics and thermosets. Thermoplastics provide strong, durable adhesion at normal temperatures, and they can be softened for application by heating without undergoing degradation. Thermoplastic resins employed in adhesives include nitrocellulose, polyvinyl acetate, vinyl acetate-ethylene copolymer, polyethylene, polypropylene, polyamides, polyesters, acrylics, and cyanoacrylics. CONTACT ADHESIVE Contact adhesives or cements are usually based on solvent solutions of neoprene. They are so named because they are usually applied to both surfaces to be bonded. Following evaporation of the solvent, the two surfaces may be joined to form a strong bond with high resistance to shearing forces. Contact cements are used extensively in the assembly of automotive parts, furniture, leather goods, and decorative laminates. They are effective in the bonding of plastics. STRUCTURAL ADHESIVE Structural adhesives are adhesives that generally exhibit good load-carrying capability, long-term durability, and resistance to heat, solvents, and fatigue. Ninety-five percent of all structural adhesives employed in original equipment manufacture fall into six structural-adhesive families: (1) epoxies, which exhibit high strength and good temperature and solvent resistance, (2) polyurethanes, which are flexible, have good peeling characteristics, and are resistant to shock and fatigue, (3) acrylics, a versatile adhesive family that bonds to oily parts, cures quickly, and has good overall properties, (4) anaerobics, or surface-activated acrylics, which are good for bonding threaded metal parts and cylindrical shapes, (5) cyanoacrylates, which bond quickly to plastic and rubber but have limited temperature and moisture resistance, and (6) silicones, which are flexible, weather well out-of-doors, and provide good sealing properties. Each of these families can be modified to provide ad hesives that have a range of physical and mechanical properties, cure systems, and application techniques. HOT-MELT ADHESIVE Hot-melt adhesives are employed in many nonstructural applications. Based on thermoplastic resins, which melt at elevated temperatures without degrading, these adhesives are applied as hot liquids to the adherend. Commonly used polymers include polyamides, polyesters, ethylene-vinyl acetate, polyurethanes, and a variety of block copolymers and elastomers such as butyl rubber, ethylene-propylene copolymer, and styrene-butadiene rubber. PRESSURE SENSETIVE ADHESIVE Pressure-sensitive adhesives, or PSAs, represent a large industrial and commercial market in the form of adhesive tapes and films directed toward packaging, mounting and fastening, masking, and electrical and surgical applications. PSAs are capable of holding adherends together when the surfaces are mated under briefly applied pressure at room temperature TYPES OF ADHESIVES Adhesive Type Sources/Properties Common Uses Animal glue Obtained from animal byproducts such as bones, blood, and hooves Binding of abrasives in sandpaper and other grinding materials Casein Main protein in milk Labels on beer bottles that do not come off in ice water, yet are recyclable Starch From corn and maize Corrugated cardboard bonding Natural rubber Not sticky enoughby itself but is used as an additive in other adhesives Self-adhesive envelopes and other pressure-sensitive adhesives; adhesives that bond to substrates on contact (like tapes) Butyl rubber/isobutylene It is elastomeric-it stretches Additive for hot-melt adhesives, window sealants, and pressure-sensitive adhesives Amino resins Water-soluble adhesives Bonding of layers in plywood and the bonding of particles in particle board Polyurethane A flexible adhesive Bonding soles to the bodies of shoes; also used in food packaging Polyvinyl acetate Common whiteglue Book bindings and labels Polyolefin/ethylene copolymer No solvents involved Hot melts Acrylates or anaerobic adhesives Cure when air is removed Adhesive used to keep nuts tight on bolts, such as those within ATMs and heavy machinery Silicone Both an adhesive and a sealant and only common adhesive that is based on silicon rather than carbon Bathtub and shower sealants; also many car applications, such as oil pans and head gaskets Uses of Adhesives:- The exact combination of reasons will vary from case to case, but advantages should be sought in the following areas:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Increased production speed. In comparison with other fabrication methods, adhesive assembly is essentially fast. Even if curing is required, this can often be accommodated off line, or combined with other processing stages such as paint curing.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Wider material selection. In contrast to welding, adhesives allow a wide freedom of choice during material specification. It is possible to mix and match material combinations to suit product function and save production costs in ways which have been impossible in the past. Traditional materials may be combined with new metal alloys, plastics, composites and ceramics to give distinct product advantages. Absorbing the full potential of this new freedom is perhaps one of the biggest challenges in finding significant market opportunities.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Design for manufacture. Adhesive assembly offers significant cost savings if material costs can be reduced and production operations can be simplified. There is sample evidence that this can be the case if the design and manufacturing functions co-operate to design or redesign the product with manufacturing in mind. New approaches can be taken to the manufacture of sub components, and castings may be combined with extrusions, sheet components and parts produced in a variety of other ways.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Better production sequences. Traditional assembly methods such as welding impose fairly rigid sequences during production, and frequently demand intermediate processing to remove contamination or rectify distortion. Bottlenecks can be removed, unnecessary operations can be eliminated, and work in progress can be reduced.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Low capital costs. Many adhesive operations involve manual application and the use of adhesive packages which have built in applicators. Even when mechanised or automated application is justified for high volume work, the equipment is usually lighter than would be used for welding.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Low production costs. This is a source of significant confusion Costs per tube of some adhesives may be high, but this should not be confused with all in production costs or cost per product. Cost comparisons should be based on the costs of the whole joining process, including plant, preparation and other pre-assembly costs, production and rectification expenses. All in cost assessments of this type provide a basis for accurate comparisons, and adhesive assembly may often give significant benefits. Advantages of Using Adhesives  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Dissimilar materials can be joined.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The bond is continuous.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Stronger and stiffer structures can be designed.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  On loading there is a more uniform stress distribution (Figure 2).  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Local stress concentrations are avoided.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Porous materials can be bonded.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Adhesives prevent catalytic corrosion.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Adhesives seal and join in one process.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  No finishing costs.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Improved fatigue resistance.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Vibration damping.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Reduced weight and part count.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Large areas can be bonded.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Small areas can be bonded accurately.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Fast or slow curing systems available.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Easy to combine with other fastening methods.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Easily automated/mechanised. Figure 2.  Stress distributions in a riveted joint and an adhesively bonded joint. Note areas of high stress concentration in the riveted joint. All these advantages may be translated into economic advantages: improved design, easier assembly, lighter weight (inertia overcome at lower energy expenditure) and longer life in service. Limitations of Using Adhesives  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Not as strong as metals.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Increasing the service temperature decreases the bond strength.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Short term handle ability is poor.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Bonded structures are usually difficult to dismantle for in service repair.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Need to prepare the surface.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Environmental resistance depends on the integrity of the adhesive.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Need to ensure wetting.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Un-familiar process controls.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Health and safety responsibility.
