Silicon Nitride Ceramic:
Plastic is a polymer compound (macromolecules) that is polymerized by addition polymerization or polycondensation reaction with monomer as raw material. Its resistance to deformation is moderate. It is between fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, and stabilizers. It is composed of additives such as agents, lubricants, and pigments.
The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named for the lipids secreted by plants and animals, such as rosin and shellac. The resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or little additives, such as plexiglass and polystyrene. Plastic raw material is defined as a kind of synthetic or natural high molecular polymer, which can be arbitrarily kneaded into various shapes and finally maintains the same shape. Plastics are important organic synthetic polymer materials and are widely used. However, the "white pollution" caused by waste plastics is becoming more and more serious. If we can understand the composition and classification of plastics in detail, it will not only help us use plastic products scientifically, but also facilitate the classification and recycling of plastics, and effectively control and reduce them. "White pollution". Plastics can be divided into two types: thermosetting and thermoplastic. The former cannot be reshaped and used, and the latter can be reproduced. Thermoplasticity has a relatively large physical elongation, generally between 50% and 500%. The force does not completely change linearly at different elongations.
The different properties of plastics determine its use in life and industry. With the advancement of technology, research on plastic modification has not stopped. It is hoped that in the near future, modified plastics can have a wider range of applications, and can even replace steel and Other Materials and no longer pollute the environment.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
