We supply high purity of Nano Silicon carbide powder.Adjust proportion alloy products according to customer's requirements

Main characteristics

Ultrafine nano silicon carbide, silicon carbide powder by variable current laser ion beam, chemical vapor deposition by variable current, high voltage discharge, can fully overcome the shortcoming of dc electric arc (inadequate response, high product impurities, poor stability of products). High purity, small particle size distribution, high specific surface area; Nano silicon carbide has stable chemical performance, high coefficient of thermal conductivity (165 w/M.K), small thermal expansion coefficient, high hardness, mohs hardness up to 9.5, the microhardness of 2840 ~ 3320 kg/was the first material abrasion resistant additives, its hardness is between fused alumina and diamond, mechanical strength is higher than fused alumina; Nano silicon carbide has excellent thermal conductivity, is also a sort of semiconductor, can at high temperature oxidation resistance; Nano silicon carbide wear-resisting, high temperature resistance, corrosion resistance, resistance to acid and alkali solvent, widely used in paint, paint, increase the wear resistance.

Apllication

1 modified high strength nylon material: nanometer SiC powders in polymer composite material compatibility is good, good dispersibility, and combined with good matrix, and the modified nylon alloy high strength tensile strength by more than 150% higher than that of ordinary PA6, wear-resisting performance increased by more than three times. Mainly for the armored tracked vehicle polymer parts, automotive steering parts, textile machinery, mining machinery lining board, the train parts under the low temperature sintering densification is reached;

2 modified special engineering plastics polyether ether ketone (PEEK) wear-resisting performance: after processing the surface of the nano silicon carbide, when adding quantity is approximately 5%, can greatly improve and raise the wearability of PEEK (increased by more than 30%);

3 of the application of nano silicon carbide in rubber tyre: adding 2% or so of the nano silicon carbide without changing collagen modified formula, and without reducing its performance and quality under the premise of its wear resistance can be increased by 20% - 40%. In addition, the application of nano silicon carbide in rubber roller, the printer fuser film, such as wear resistance, heat, heat resistance and other rubber products;

4 nanometer SiC composite coating metal surface: the nano-scale particles second hybrid particles, nickel as the matrix metal, the metal surface to form high density, bonding strength very good composite electrodeposition, the metal surface with a hard (wear) and antifriction (self-lubricating) high temperature resistant characteristics. Greatly improve the composite coating microhardness, wear resistance increase 2-3 times, improve the service life of 3-5 times, the adhesion strength of the coating and substrate increased by 40%, covering ability strong, uniform coating, smooth and delicate;

5 other applications: high performance structure ceramics (such as rocket nozzle, the nuclear industry, etc.), absorbing material, wear-resistant lubricating grease, high-performance brake pads, high hardness, wear resistance of powder coatings, composite ceramic enhanced toughening, etc.; In the field of aerospace industry structure, functional coating, protective coating, coating absorbing materials, stealth materials, etc.; Tanks and armoured vehicles protective armor; For ceramic cutting tool, cutting tool and measuring tool and die; As a special use structural ceramics, functional ceramics, engineering ceramics; Ignition; Electrical industrial electric heating elements, far infrared generator.
