China Sio2 Cao Wollastonite

Introduction:
Wollastonite
Wollastonite(calcium metasilicate,or CaSiO3) it's a naturally occuring white mineral which acts as an acicular reinforcing fillerIndustrial Equipment & Components .
1) Replace asbestos to be apply for friction material field
2) Replace glass fibre
3) Apply for plate and frame of filter press
3) Widely applied in ceramic, Electrical Control System paint,as electrode coating, plastic,insulating material, paper and ect.
Application:
Wollastonite is a kind of natural minerals, its formula is CaSiO3 (Calcium-metasilicate). based on its properties of high whiteness, natural brilliant acicular particle shape, besides of there properties, our wollastonite are processed with advanced technics and eqFastener & Fitting uipments, with high aspect ratio, good reinforcement and sealing property, more and more, it replaces asbestos, fiber talc, glass fiber, used in high polymer engineering plastics, special plastics, friction materials, etc sides. Also the wCustomized Service for Electronics ollastonite are widely used for Ceramic-body, metallurgy, Painting, Welding and Glaze etc application.

Usage
--At present, it's mainly applied to aint, plastics, rubber, electricChemical Equipment & Machinery welding, glass, electron industry, metallurgy and paper making, Frictionmaterial, Construction,ceramic industry, and secondly used as metallurgy protecting slag and paint.
--Further, it can be used as electrode coating, mountain cork substitute, abradant binding agent, compound of glass and stuffing of rubber, plastic, insulating material and paper.
--Some wollastonite can be used as finishing material of building or compound of white cement
