1. Polymer polymer is also called plastic; plastic used as mechanical engineering data is called engineering plastic. It is based on synthetic resin; it is also rich in various plasticizers, stabilizers, antioxidants and antistatic agents. , organic materials for flame retardants, curing agents, reinforcing materials and fillers.
2. Carbon Graphite Information Graphite is a type of non-metal material composed of carbon. It is one of the three isomers of carbon; it is a hexagonal system; each layer is composed of a hexagonal ring; the layers are parallel to the layer; Ordered stacked crystal structure. Graphite is divided into natural graphite and artificial graphite according to the origin. Artificial graphite is made of carbonaceous data by high temperature graphitization above 2500 ° C. Carbon graphite is generally good in conductivity, heat resistance, wear resistance, Self-smoothness, high temperature stability; strong chemical resistance; high thermal conductivity than polymer; small coefficient of linear expansion. Collision factor and wear rate with chrome surface at atmospheric and room temperature are very low. When the humidity is very low, the smoothness will be lost. The wear-resistant coating can improve the wear resistance of carbon graphite. Graphite can be used not only as a solid smoothing agent; but also in resin, metal, ceramics, etc.; Sexuality; can also be directly used as a sub-data for conflicts; such as making bearings for papermaking, wood processing, textiles, food, etc.; high-temperature sliding bearings; seals; piston rings; scrapers, etc. "Represents the symbol M; has four series: carbon graphite materials, electrical materials graphite, resin, carbon graphite composite materials and metal materials.
3. Ceramic material ceramics are inorganic non-metallic natural minerals or artificial compounds; they are destroyed, formed and sintered at high temperature; non-metallic materials composed of many inorganic non-metallic small crystals and glass phases. Inorganic non-metallic natural mineral deposits; For example, clay, feldspar, quartz, etc. are made of traditional ceramics. The artificial ceramics are made of special materials. The ceramics used in mechanical engineering are usually alumina, magnesia, zirconia, lead oxide, Artificial ceramics such as titanium oxide, silicon carbide, boron carbide, silicon nitride, boron nitride, etc. are special ceramics made of materials. The functions of ceramics are largely determined by their microstructure; including grain size and dispersion; glass The composition and content of the phase; the nature, content and dispersion of the impurities. The microstructure is determined by the material, composition and manufacturing process. The properties of the ceramic are high hardness and compressive strength, high temperature resistance, wear resistance, oxidation resistance, Good corrosion resistance, brittleness, impact resistance and no ductility. Ceramics are a new type of bearing material without smooth bearings; especially SiC and Si3N4; their strength , heat resistance and corrosion resistance are very good; conflict function is also very good.
