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;
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. |
