Main features: Nano-silicon carbide and
ultra-fine silicon carbide powder are prepared by special process methods, with
high purity, small particle size distribution and high specific surface area.
Nano-SiC has stable chemical properties, high thermal conductivity (165W/MK)
and thermal expansion coefficient. Small, 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, or a
semiconductor, can resist oxidation at high temperature; nano-silicon carbide
wear-resistant, high temperature resistance, corrosion resistance, acid and
alkali resistant solvents, 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);
3. Application of 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;
5. other applications: high-performance
structural ceramics (such as rocket nozzles, nuclear industry, etc.), absorbing
materials, anti-wear grease, high-performance brake pads, high hardness
wear-resistant powder coating, composite ceramic reinforcement and toughening;
aerospace industry Structural coatings, functional coatings, protective
coatings, absorbing materials, stealth materials, etc.; protective armor for
tanks and armored vehicles; can be used as ceramic knives, cutting tools,
measuring tools, molds; structural ceramics, functional ceramics for special
purposes, Engineering ceramics; igniters; electric heating elements for the
electrical industry, far-infrared generators.
