Application direction
1. Modified high strength nylon material: my company's nano SiC powder in polymer composite materials good compatibility, good dispersion, and basic good bonding, modified high strength nylon alloy tensile strength than ordinary PA6 increased by more than 150%, wear resistance increased by more than 3 times. It is mainly used for polymer parts of armored tracked vehicles, automobile steering parts, textile machinery, mining machinery lining, train parts, etc., which can be densified by sintering at low temperatures;
2. Modified special engineering plastic polyether ether ketone (PEEK) wear resistance: our company after surface treatment of nano silicon carbide, when the addition amount is about 5%, can greatly improve and improve the wear resistance of PEEK (increase the original 30% or more);
3. The application of nano silicon carbide in rubber tires: adding about 2% nano silicon carbide is modified without changing the original rubber formula, and its wear resistance can be increased by 20%-40% without reducing its original performance and quality. In addition, 20 nanometer silicon carbide is used in rubber roller, printer fixing film and other wear resistant, heat dissipation, temperature resistance and other rubber products;
4. Metal surface nano SiC composite coating: The use of nano particles second mixed particles, nickel as the matrix metal, the formation of high density on the metal surface, the binding force is very good electrodeposition composite coating, the metal surface has the characteristics of super hard (wear) and anti-wear (self-lubrication) high temperature resistance. The microhardness of the composite coating is greatly increased, the wear resistance is increased by 2-3 times, the service life is increased by 3-5 times, the binding force between the coating and the substrate is increased by 40%, the covering ability is strong, the coating is uniform, smooth and meticulous;
5. Other applications: high-performance structural ceramics (such as rocket nozzles, nuclear industry, etc.), wave absorbing materials, anti-wear lubrication grease, high-performance brake pads, high-hardness wear-resistant powder coatings, composite ceramics strengthening and toughening, etc.; Structural coatings, functional coatings, protective coatings, wave absorbing materials, stealth materials, etc., in the field of aerospace industry; Protective armour for tanks and armoured vehicles; Can be used for ceramic cutting tools, cutting tools, measuring tools, molds; Can be used for special purpose structural ceramics, functional ceramics, engineering ceramics; Igniter; Electric heating elements for electrical industry, far infrared generator.
