application
1. Modified high strength nylon material: nano silicon carbide powder has good compatibility, good dispersion and good baSiC adhesion in polymer composites. The tensile strength of modified high-strength nylon alloy is increased by more than 150% compared with ordinary PA6, and the wear resistance is increased by more than 3 times. It is mainly used for high polymer parts of armored tracked vehicles, automobile steering parts, textile machinery, mining machinery lining plate, train parts, etc., which can achieve densification under low temperature;
2. Wear resistance of modified special engineering plastics peek: when the content of PEEK is about 5%, the wear resistance of PEEK can be greatly improved (increased by more than 30%);
3. Application of nano silicon carbide in rubber tire: the wear resistance of rubber tire can be increased by 20% - 40% by adding about 2% nano SiC without changing the original rubber formula and without reducing its original performance and quality. In addition, nano SiC is used in Rubber Cots, printers, fixing film and other wear-resistant, heat dissipation, temperature resistant rubber products;
4. Nano silicon carbide composite coating on metal surface: the second mixed particle of nano particles is adopted, and nickel is the base metal. The electrodeposited composite coating with high density and good adhesion is formed on the metal surface. The metal surface has the characteristics of super hard (wear-resistant) and anti-wear (self-lubricating) and high-temperature resistance. The results show that the microhardness of the composite coating is greatly improved, the wear resistance is increased by 2-3 times, the service life is increased by 3-5 times, the adhesion between the coating and the substrate is increased by 40%, and the coating is uniform, smooth and meticulous;
5. Other applications: high performance structural ceramics (such as rocket nozzles, nuclear industry, etc.), absorbing materials, anti-wear lubricating grease, high-performance brake pads, high-hardness wear-resistant powder coatings, composite ceramic reinforcement and toughening, etc.; structural coatings, functional coatings, protective coatings, absorbing materials, stealth materials, etc. in aerospace industry; protective armor for tanks and armored vehicles; ceramic knives Tools, cutting tools, measuring tools, molds; structural ceramics, functional ceramics, engineering ceramics for special purposes; igniters; electric heating elements for electrical industry; far infrared generator.
