Product Description
Wollastonite, a single-chain silicate mineral, is mainly composed of Ca3Si3O9. It is a kind of non-toxic, tasteless, non-radioactive and other advantages gradually replace the harmful to human health of asbestos, become the new raw material of environmental protection building materials in the new century.
Application
1, paint and coatings industry: in the paint with wollastonite filler or emulsion, you can get high-quality bright colors of paint, and have the coating and anti-aging properties. White wollastonite is a good raw material for high-quality white paint and soft pastel paint, easy to brush, the surface of a slide, has a high resistance to weathering.
2, rubber and plastics industry: rubber and plastic can be done to strengthen the filler, with the thermosetting and thermoplastic resin and mold resin model, with good thermal shock resistance and enhance stability. Filled in the epoxy resin, before plastication has low water absorption, low dielectric constant and low viscosity, good performance.
3, ceramic industry: ceramic raw materials by adding the right amount of wollastonite, can significantly reduce the firing temperature, shorten the time of firing to achieve a fast low-temperature firing, a large number of fuel savings, significantly reduce product costs. At the same time, improve the mechanical properties of products, reduce product cracks and stripes, improve product yield.
4, other aspects: wollastonite can also be used for steelmaking slag, welding electrode coating, ceramic mold, grinding materials and grinding wheel production, paper filling agent, the production of white cement, manufacturing special electrical ceramics and other rare minerals raw material.
