Wear resestance powder for coating production
A coating is a covering that is applied to the surface of an object, or substrate. The purpose of applying the coating may be decorative, functional, or both.Coating can be liquid,also can be solid eg:powder coatings.
During coating prodution,wear resistance powder usually are used as additives to improve the wear resistance and hardness of coatings,then increase the durability of the coating.
Today just introduce the wear-resistance powder:
Wear resistance powder we mentioned here,including white fused aluina,brown fused alumina,black silicon carbide ,green silicon carbide and so on,are important industrial material.Because they own high hardness and good wear-resistance,abrasives are used in coating production.
The properties of the wear resistance powder to make they work in coatings:
Black silicon carbide and green silicon carbide mainly made of silicon carbide(SiC) which is about 98%min,white fused alumina and brown fused alumina are Aluminum oxide(Al2O3).All of then own high hardness and wear resistance,only less than diamond.Besides,abrasives also posses high crush strength,Impact resistance,Corrosion resistance etc,making them can work in bad environment long time stably.
Specifically speaking,silicon carbide has higher hardness than fused alumina,the exact data as follows:
Green silicon carbide:9.4
Black silicon carbide:9.15
White fused alumina:9.0
Sometimes if the producers take the coloring into consideration,most of them will tend to use white fused alumina,because white is easy to coloring and also low cost comparativelly.
Exact using cases from our customers:
1.Epoxy floor coating production: white fused alumina JIS180 JIS#220 #240 #280 #320 etc
2.Non-stick Teflon coating: green silicon carbide JIS#400 #600 #800 #1000 #1200 #1500 F600 etc
3.Powder coating: white fused alumina 2000mesh or green silicon carbide 2000mesh
4.Anti-skid coating:green silicon carbide #400 #600 #800 #1000 #1200 etc
5.UV coating:green silicon carbide #400 #600 #800 etc
6.Foundry coating:brown fused alumina #240 #280 #320 #360 #400 #500 #600 #800 #1000 etc
7.Zinc-rich coatings:white fused alumina/green silicon carbide #400 #600 #800 etc
Besides,also have wear resistance,high temperature resistance coatings use black silicon carbide or other abrasives too.
