Task Essay Example Venture Essay Venture Essay The polymer will lose its high bendable quality as more water is creature units reinforced together. Polyvinyl acetic acid derivation is a rubbery manufactured polymer. This polymer is a segment in stick. Blending borax in with polyvinyl acetic acid derivation will make it cross-connection and structure ooze. Cross-connecting is a bond that joins one polymer chain to another. (see graph beneath). Borax, which is additionally, known as sodium borate is a non-poisonous substance and has a wide-assortment of employments. We have to utilize our insight into science to clarify the physical attributes and synthetic conduct of a specific material. Our target in this examination was to make a polymer ball that was both reverberation inviting and nontoxic. Strategies/Procedures The accompanying things were utilized: - Polyvinyl liquor - Sodium borate - Polyvinyl acetic acid derivation strong - Starch During week one of our test we utilized the entirety of the fixings that were given to us. A 10:1 proportion between polyvinyl liquor and sodium borate was utilized. We utilized this proportion in light of the fact that while directing exploration, there was a comparative test to the polymer ball and it said a 10:1 proportion was utilized. Ml of borax and ml of polyvinyl liquor was filled a shopping center measuring utencil. At that point the blend was mixed for around 10 minutes until the blend turned into a clingy substance. Ml of polyvinyl acetic acid derivation was hen filled the blend. The blend was mixed for 2-3 minutes. During week two we should change our blend and furthermore make our polymer ball impervious to the warmth and cold since it would have been sent from Florida to New Mexico to Alaska. During this investigation we changed our analysis utilizing less fixings and less substances. The main fixings utilized were the polyvinyl liquor and the sodium borate. Ml of polyvinyl liquor and ml of sodium borate were blended in a shopping center measuring glass. The blend was mixed until it began to thicken which took around 10-15 minutes. The blend was removed from the recepticle, and folded into a ball for around 5 minutes at that point set back in the measuring glass and let it sit for 20 minutes. Following 20 minutes, the blend turned out to be less clingy and was simpler to fold into the state of a ball. Since we should make a ball that was impervious to various atmosphere temperatures, the polymer ball was part into two. Half of the ball would be in high temp water and the other would be in ice. Results/Discussion When the Papa and sodium borate were combined, the blend turned out to be exceptionally clingy and a great deal of air bubbles were framed and the blend likewise frothed. The blend crackpot the state of the measuring glass, however when it was removed from the container and was left to sit on the table, the polymer would straighten out. This is called shape memory, materials that can recollect their shape after a bending happens and can reconfigure its shape upon a boost. In the second seven day stretch of this investigation we intended to not utilize starch, or polyvinyl acetic acid derivation strong did nothing to our item. To test the polymer ball regarding whether the ball could withstand diverse temperature atmospheres. Two tests were performed. An ice shower test, and a bubbling water test. One portion of the ball was coloring in a measuring utencil of ice. When the polymer was put in the container it began to steam and promptly it began to freeze. The polymer likewise began to level out. At the point when it was removed from the ice it was extremely dangerous and difficult to hold. It was likewise hard to fold into a ball. Be that as it may, after it sat in room temperature it was simpler to shape into a ball and still conveyed the bob that a fun ball ought to have. In bubbling water try, water was bubbled in a container with the utilization of a Bunsen burner. After the water was bubbling we set the polymer ball into the water and it softened UT didnt completely break up in the water. There was a layer of the polymer ball drifting in the water. We gathered the layer and put the substance into a measuring utencil. At the point when the substance chilled off and had returned to room temperature, the substance turned out to be exceptionally stretchy. The polymer could likewise be folded again into a ball. All in all, we couldn't make a polymer ball that would have the option to withstand distinctive atmosphere changes, however had the option to make the fun ball. The polymers we made bounced despite the fact that they were somewhat floppy and werent immaculate circles. The polymer adhered to all surfaces however was anything but difficult to pull off. It was pliant and simple to shape. It couldnt be pulled separated or extended, Just crunched and pressed. When the polyvinyl acetic acid derivation strong was added to our first blend it had stick like shading and no progressions were made to the substance. At the point when you add borax answer for polymers like PA, it cross-interfaces the two polymers together like a net. Contingent upon the amount of every fixing is blended you can either make a blend that is disgusting or stretchy. By including cornstarch the blend will have the option to twist and stretch the blend. Most plastics are polymers. For instance PVC pipes is the constant connecting of a similar particle.
