The project that I will be testing and researching is if milk can create plastic and which acid creates the hardest plastic. I chose to do this project because it was very interesting to me and I thought that this would be a very interesting way to reduce the harmful gasses that we produce. Also if it works then this could be a thing that changes mankind by reducing pollution and helping the human race live a healthier life and maybe it would even help make the Earth live a little longer than…
Plastic is a new foundation for human life: food comes packaged in plastic, sports are played on grass made out of plastic, supplies are wrapped in plastic, and accessories are encased in plastic. Plastic also has a way of getting into trees, bushes, oceans, animals, and makes the environment look awful. As of watching our backyards and oceans get filled with plastic bags, we have realized the trouble plastic causes for the environment. San Francisco, California, Laredo, and Eagle Pass have…
Plastics are a material currently being used all around the world. As the production of this synthetic polymer has increased, it has become almost impossible to completely avoid interaction with a plastic material. With the discovery of this practical material, positives and negatives were discovered too. Plastics have a strong effect on the environment and human health. During manufacturing, additives are put in that can be harmful to each of these important aspects. Due to their synthetic…
2. Basic theories and principles 2.1 Chemical vapor deposition 2.1.1 Definition of chemical vapor deposition Chemical vapor deposition (CVD) is a versatile process which is widely applied to produce coatings, powders, fibers and monolithic components [1]. Applying the chemical vapor deposition, it is possible to produce alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the…
polyurethanes were first developed by Otto Bayer and coworkers in 1937. Shortly thereafter, Schollenberger and coworkers used formula modification to prepare elastomeric polyurethane products from Bayer's products that were like nylon or other engineering plastics in physical characteristics. PUs are widely used in coatings, flexible and rigid foams, elastomers, and composites. Reasons for the use of polyurethane coatings include: high performance characteristics such as flexibility, toughness,…
According to cerakoteguncoatings.com (2017), Cerakote is a Polymer-Ceramic coating that can be applied to metals, plastics, polymers and wood. Cerakote is used on; knives, weapons, tools, some electronic covers, glasses and anything durable that needs a tough coating. This ceramic thin-film coating is intended to offer an appealing finish with unequaled performance. The ceramic coating of Cerakote provides the advantage of having extraordinary; adhesiveness, pliability, corrosion and wear…
In gloves industry, and for the maximum care of hands, Polyurethane-made gloves has shown the most remarkable effect than any other material. Known as one of the most versatile quality polymers, Polyurethane gloves are in huge demands at the consumer end. Well, what are the qualities that make a Polyurethane glove the best? To be honest, you can't find much stronger grip (and no sticky sensation) in a glove made by Polyurethane than any other material. The other qualities of this material are…
The polyurethane segments show high intersegment attraction such as hydrogen bonding and may be able to crystallize and form hard segments. In such polymers hard segments with Tg well above normal ambient temperature are separated by polyol soft segments, which in the mass are rubbery in nature. Hard and soft segments are arranged alternate along the polymer chain. Fig.7. Polyurethane chain configuration [32] 4.2.2. Polyurethane properties and advantages for product development…
one of the reasons why it has become popular. Insulation is necessary to protect the roof from weather getting into the cracks of the wood shingles on the roof. If left alone for a long time, this can cause some damage on the roof. Installing foam plastic on these cracks will protect the roof from further effects of weather. It is in liquid form, which expands several times its initial size when sprayed on a surface. The spray foam is polyurethane foam or SPF that is used to insulate almost…
Egg Drop Project For my egg drop project, at first I planned to do a triangle shape around the egg with straws and tape the straws together. Then I changed my project to a square like shaped with enough flexibility to squeeze the egg into it. I used straws because it would “soften” the fall. I also used a parachute to make it a smoother fall. After I completely figured out what I was doing I started building. I hot glued two straws against one straw until I had a square. After I…
