Alumina Zirconia electrical Ceramic Plunger shaft insulator
Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
Improve the scratch resistance and durability of UV-curable coatings. These UV-curable coatings are used in a variety of areas that require high abrasion resistance, such as plastic floor nano-alumina XZ-L690 in a white fluffy powder state, and the crystal form is γ-Al2O3. The particle size is 20 nm; the specific surface area is ≥160 m 2 /g. Uniform particle size distribution, high purity, excellent dispersion, high specific surface area, high temperature inertness, high activity, active alumina; porosity; high hardness, good dimensional stability, strong surface acidity and certain The surface is alkaline and is widely used as a new green chemical material such as a catalyst and a catalyst carrier. It can be widely used in the reinforcement and toughening of various plastics, rubber, ceramics, refractory materials, etc., especially to improve the compactness, smoothness, thermal fatigue, fracture toughness, creep resistance and polymer materials of ceramics. Wear resistance is particularly significant. Excellent dispersion, in solvent water; solvent ethanol, propanol, propylene glycol, isopropanol, ethylene glycol monobutyl ether, acetone, methyl ethyl ketone, benzene, xylene, without adding dispersing agent, stirring and stirring can be sufficient Disperse evenly. It is excellent for use in epoxy resins, plastics, etc.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
