Technical Parameters

Nano-SiC and ultra-fine silicon carbide powder are prepared by special process method, which has high purity, small particle size distribution range and high specific surface area. Nano-SiC has stable chemical properties, high thermal conductivity (165W/MK) and small thermal expansion coefficient. High hardness, Mohs hardness of 9.5, microhardness of 2840~3320kg/mm2 is the first material wear-resistant additive, its hardness is between corundum and diamond, mechanical strength is higher than corundum; nano-silicon carbide has excellent thermal conductivity It is also a kind of semiconductor, which can resist oxidation at high temperature; nano silicon carbide is wear-resistant, high temperature resistant, corrosion resistant, acid and alkali resistant, widely used in paints and paints to increase wear resistance.

Application field

1 Modified high-strength nylon material: Nano-SiC powder has good compatibility, good dispersibility and good matrix adhesion in polymer composites. The tensile strength of modified high-strength nylon alloy is more than 150% higher than that of ordinary PA6. The wear resistance is improved by more than 3 times. Mainly used for armored track vehicle polymer parts, automotive steering parts, textile machinery, mining machinery linings, train parts and other sintering at lower temperatures to achieve densification;

2 Modified special engineering plastics Polyetheretherketone (PEEK) wear resistance: Nano-silicon carbide after surface treatment of our company can greatly improve and improve the wear resistance of PEEK when the addition amount is about 5% (improve the original 30% or more);

Application of 3 nanometer silicon carbide in rubber tires: adding about 2% of nano silicon carbide can be modified without changing the original rubber formula, and its wear resistance can be improved by 20% without reducing its original performance and quality. -40%. In addition, 40 nanometer silicon carbide is used in rubber rubber rollers, printer fixing films and other rubber products such as wear resistance, heat dissipation and temperature resistance;

4 metal surface nano-SiC composite coating: using nano-scale particles second mixed particles, nickel as matrix metal, forming high density on the metal surface, very good adhesion electrodeposited composite coating, the metal surface is super-hard (wear-resistant ) and anti-wear (self-lubricating) high temperature resistance. The micro-hardness of the composite coating is greatly improved, the wear resistance is improved by 2-3 times, the service life is increased by 3-5 times, the bonding force between the plating layer and the substrate is increased by 40%, the covering ability is strong, the plating layer is uniform, smooth and fine;
