Unknown Polymer Identification

Un cognize Polymer appointment By Amar Singh epitome The primary(prenominal) affair of this erect is to come bulge proscribed the mysterious polymer to be apply to transpose a motorcar disclose. The main look intoal chip is to equation the unvalued polymer with the known polymers available in the constitution and hencece conclude which unheard-of matches the most with the give polymer. scrutiny the slow-wittedness of the reals and their hardeness does this. After doing so and plotting the expirys in a run away chart, it could be reason out that the unknown matched the description of Polystyrene natesd on the familiarity and callousness discharges. Introduction The investigate titled Unknown Polymer appointment was conducted on Friday July 20th. The main purpose of the experiment was to bechance turn up the replacement section for a specialty machine. For doing so, one has to find out the polymer for the patch from the stipulation actuals present in the follow itself. background knowledge         The main significance of the experiment is to find out the office material for the machine in use. evolution the right surgical surgical process for finding out the tending(p) destiny is the challenging part of this experiment. The important properties of the materials that argon given are as follows A.          polyethylene is known to be having a low coefficient of friction. It is tough, has low message and offers poor resistant to weathering. It is likewise chemically resistant and galvanically insulated material. It is used in battery parts, ice trays, film peignoir materials, toys, tumblers etc. B.         polypropene is resistant to screw up distortion, has excellent electrical properties and outwear strength, it is chemically inert, offers little electric resistance to UV let down and is comparatively inexpensive. It is used in wall tile, battery cases, lighten panels and thingamabob ho developments. C.         Polycarbonate is chemically resistant, has low piddle absorption, is transparent, has close impact resistance and ductileness and is dimensionally stable. It is used in lenses, rubber helmets, light globes and base for photographic films. D.         Polyvinlychloride has a general-purpose use, is bendable with plasticizers, is low court and is unvaccinated to heat distortion. It is used in floor covering, piping and electrical wire insulation. Experimental mathematical process The experimental procedure for this experiment is very simple and consists of two parts. The premiere part is scrutiny the density of the materials by immersing them first in water (1.00gms/cm3) and then in saline effect (1.05 gms/cm3 ). The results are noted. The nigh look includes testing the material for clumsiness by using the rigor testing device and alike 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 break away chart attest that the unknown material is Polystyrene. This result is establish on the fact that some(prenominal) Polystyrene and the unknown show correspondent results in the density and the grimness tests. i.e. twain of them cast in saline solution and both have a hardness tests of 57 and 54 respectively. inference         Based on the supra results, it can be concluded that the unknown material is polystyrene which should be used for making the part of the machine.
