The characteristics of wollastonite:
Wollastonite is a chain silicate is a fibrous, needle. Due to its special crystal structure, the crystal structure determines its properties, and the silica fume has good insulating property, high whiteness, good dielectric property and high heat resistance and weather resistance. Because the silica fume is widely used in ceramics, chemical industry, metallurgy, paper making, plastic, paint and other fields..
Effect of wollastonite:
With a good reinforcing coating grade wollastonite can improve the toughness and durability of the coating, and can keep the coating with smooth surface and good gloss. And improve the anti wash and anti weathering performance, but also can reduce the amount of paint and ink oil absorption and maintain basic, with anti corrosion ability. Can get high quality color bright paint, and has a good average coating properties and anti-aging properties. The coating can obtain better mechanical strength, increase durability, enhance adhesion and corrosion resistance. Good coverage and adhesion.
Plastic rubber grade wollastonite has unique acicular fiber, has good insulation, wear resistance, and high refractive rate. Plastic, rubber products, better filling materials. Characteristics and performance: wollastonite powder can improve the impact strength, enhance liquidity and improve the tensile strength, impact strength, linear stretching and contraction rate.
The friction wollastonite powder is a kind of special needle structure, physical and mechanical performance of wollastonite unique. The friction resistance and heat resistance of the finished product are greatly enhanced. When the product is filled to the inside, it can improve the friction flexibility and stability and so on.
