Alumina Ceramics:
Stabilizers mainly refer to agents that maintain the stability of polymer plastics, rubber, synthetic fibers, etc., and prevent their decomposition and aging. In order to prevent the synthetic resin from being decomposed and damaged by light and heat during processing and use, and to extend its service life, stabilizers must be added to the plastic. Commonly used are stearate and epoxy resin. The amount of stabilizer is generally 0.3 to 0.5% of the plastic. The colorant can make the plastic have various bright and beautiful colors. Commonly used organic dyes and inorganic pigments as colorants. The natural color of synthetic resin is mostly white translucent or colorless and transparent. Colorants are often used in industrial production to increase the color of plastic products. The function of the lubricant is to prevent the plastic from sticking to the metal mold during molding, and to make the surface of the plastic smooth and beautiful. Commonly used lubricants include stearic acid and its calcium and magnesium salts. Prevent the plastic from being heated and oxidized during heat molding or high-temperature use, which will cause the plastic to turn yellow and crack. In addition to the above additives, flame retardants, foaming agents, antistatic agents, conductive agents, magnetic permeability agents, compatibilizers, etc. can also be added to the plastic. To meet different requirements. Plastics are excellent insulators, so they are easily charged with static electricity. Antistatic agents can impart mild to moderate electrical conductivity to plastics, thereby preventing the accumulation of static charges on the products. Generally refers to plastics with large output, wide use, good formability and low price. There are five types of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). These five types of plastics account for the vast majority of plastic raw materials, and the rest can basically be classified into special plastic varieties, such as: PPS, PPO, PA, PC, POM, etc., they are used in daily life products very little, mainly It is applied in high-end fields such as engineering industry, national defense technology, etc., such as automobile, aerospace, construction, communication and other fields. Plastics are classified according to their plasticity and can be divided into thermoplastics and thermosetting plastics.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
