Unknown Polymer Identification

incomprehensible Polymer appointment By Amar Singh Abstract The main part of this prove is to fuck off bulge let on the outlander polymer to be used to transpose a machine disclose. The main observational routine is to equation the unnoticeable polymer with the known polymers available in the organization and thence conclude which unknown matches the most with the condition polymer. Testing the s number 1-wittedness of the reals and their hardeness does this. After doing so and plotting the expirys in a flow chart, it could be concluded that the unknown matched the description of Polystyrene natesd on the tightness and hardness tests. Introduction The prove titled unacknowledged Polymer Identification was conducted on Friday July 20th. The main purpose of the experiment was to find out the replacement section for a specialty machine. For doing so, peerless has to find out the polymer for the part from the given actuals present in the company itself. background knowledge         The main significance of the experiment is to find out the office material for the machine in use. Developing the right surgical operation for finding out the given part is the challenging part of this experiment. The important properties of the materials that be given are as follows A.         polythene is known to be having a low coefficient of friction. It is tough, has low capacity and offers poor kind to weathering. It is also chemically resistant and electrically insulated material. It is used in battery parts, ice trays, film negligee materials, toys, tumblers etc. B.         polypropene is resistant to heat distortion, has excellent electrical properties and moil strength, it is chemically inert, offers little electric resistance to UV climb down and is comparatively inexpensive. It is used in wall tile, battery cases, lightening panels and contrivance ho developments. C.         Polycarbonate is ch! emically resistant, has low piddle absorption, is transparent, has good allude resistance and ductility and is dimensionally stable. It is used in lenses, safety helmets, light globes and base for photographic films. D.         Polyvinlychloride has a general-purpose use, is flexible with plasticizers, is low court and is susceptible to heat distortion. It is used in traumatize covering, piping and electrical wire insulation. Experimental Procedure The observational office for this experiment is very simple and consists of two parts. The starting time part is testing the density of the materials by immersing them first in water (1.00gms/cm3) and then in saline solution solution (1.05 gms/cm3 ). The subjects are noted. The nigh step includes testing the material for hardness by using the hardness testing device and similarly the result for this test are also noted down. Results and Discussions         The results of the experimental procedure were as follows.

                                                     The results from the flow chart attest that the unknown material is Polystyrene. This result is based on the fact that some(prenominal) Polystyrene and the unknown show similar results in the density and the hardness tests. i.e. both of them cast in saline solution and both pull in a hardness tests of 57 and 54 respectively. Conclusion         establish on the above results, it can be concluded that the unknown material is polystyrene which s hould be used for making the part of the machine. s! upplement Polymer          compactness in water         Density in saline          inclementness test Polyethylene         Floated         N/A         N/A Polypropylene         Floated         N/A         N/A Polystyrene         Sank         Floated         57 Polycarbonate         Sank         Sank         N/A Poly-Vinyl chloride         Sank         Sank         N/A Unknown         Sank         Floated         N/A If you want to get a large essay, rear it on our website: OrderCustomPaper.com
