Plastic is a material that has kekristalan degrees lower than the fiber, and can be softened or printed at high temperatures (temperatures above the glass transition temperature of the room), if not a lot of serial cross. Plastic is a branched or linear polymers that can be melted over heat use. Plastics can be printed (and reprinted) in accordance with the desired shape and needed by using injection molding and extrusion processes.
The term plastic covers polymerization products of synthetic or semi-synthetic. They are formed from organic condensation or addition polymers and may also consist of other substances principle of food preservation to improve performance or economics. There are few natural polymers, including plastics. Plastics can be formed into a film or synthetic principle of food preservation fiber. The name is derived from the fact that many of them are "malleable", has plasticity properties. Plastics are designed with so much variation in properties that can menolerans hot, hard, "reliency" and others. Coupled with the ability to adapt, the general composition and light weight make sure the plastic principle of food preservation is used in almost all industrial fields.
Development of plastics derived from the use of natural materials (such as chewing gum, "shellac") up to a natural material that chemically modified (such as: natural rubber, principle of food preservation "nitrocellulose") and finally to man-made molecules (such as epoxy, polyvinyl chloride, polyethylene).
Every day people are constantly using items made from plastic. Ranging from simple equipment such as cutlery (eg, plates, cups, and spoons) to sophisticated electronic equipment (eg mobile phones, laptops, and vehicles). Most people still do not know the types of plastics that are safe to use according to its function. As a result, many diseases that can be said to pose a very dangerous and lead to death such as cancer.
Everyone must be familiar with this one material, plastic. Appliances in the kitchen, in the bathroom, in our room, almost everything is made of plastic. The objects around us a lot of plastic. In fact, a person's face can be made good as desired by performing plastic surgery.
No that is soft plastic (celluloid). This type of plastic invented by John Wesley Hyatt. The material is a mixture of cellulose nitrate and camphor dissolved in alcohol, and then generate pastik called celluloid. Celluloid is highly flammable. Because it is less resistant to heat, in a variety of industrial plastic goods is replaced principle of food preservation by another type of plastic that we often encounter now is bakelite.
This heat-resistant plastic that was first discovered by Leo Hendrik Baekeland, a chemist Belgian Americans. Baekeland was born in Ghent, Belgium, on 14 November 1863. Bakelite, which its name is taken from the name of Baekeland's actually not the first finding principle of food preservation because previously he had discovered called principle of food preservation Velox photographic paper.
Baekeland an intelligent student. He likes ngulik, tamper with, try everything. During school he has always been a champion so that at age 16 he had graduated from high school (high school). Because of his intelligence anyway, he got a scholarship to go to college at the University of Ghent. For three years he was in college and at the age of 19 years he had become a scholar. In 1884, or at the age of 21 years he has received a doctoral degree maxima cum laude with honors. Later he taught at the university principle of food preservation until 1889.
Baekeland enjoys principle of food preservation traveling and photographing. He frequently travels to foreign countries such as France and Britain to. In 1889, he received a scholarship to study in the United States for three years. Actual principle of food preservation scholarship for three years instead he decided to settle in the United States until he was changing citizenship. Because the hobby is like shooting, then he got a job in photography company. At that time, to print images on paper film negatives should use sunlight. Baekeland thought it would inconvenience. Especially if you have to print at night or when the weather is rainy and no sun. In a short time he managed to create so-called Velox photographic paper. With this paper, without any sunlight and the film can be processed as a substitute for sunlight principle of food preservation is by using light. To support its findings, the
