Architecture paint grade Wollastonite powder

Description:

Wollastonite is a kind of chain metasilicate, which is generally fibrous and needle-shaped. Because of its special crystal morphology and crystal structure, wollastonite has good insulation, high whiteness, good dielectric properties and high heat and weather resistance. Because wollastonite is widely used in ceramics, chemical industry, metallurgy, papermaking, plastics, coatings and other fields.

Wollastonite is a multifunctional industrial mineral raw material with needle-like and fibrous crystal morphology, high whiteness and unique physical and chemical properties. The following are the main uses of wollastonite:

Application:

• Building materials industry:

wollastonite powder can be used to produce calcium silicate board, cement fiberboard and fire-proof sound insulation board. Because wollastonite fiber has the advantages of non-toxic, tasteless and non-radioactive, it reduces environmental pollution and production cost. Improve impact resistance, bending strength and wear resistance; Good corrosion resistance, sound insulation, heat insulation, waterproof, insulation and other characteristics.

• Paint and coating industry:

Wollastonite powder as a filler for paints and coatings can improve the physical and chemical properties, durability and weatherability of products, reduce the gloss of paints, enhance the expansion ability of coatings, reduce cracks, and also reduce oil absorption and enhance corrosion resistance. Needle-shaped wollastonite powder has good smoothness, high color coverage and uniform distribution, and has the characteristics of ultraviolet resistance.

• Ceramic industry:

Adding appropriate amount of wollastonite powder into ceramic raw materials can greatly reduce the sintering temperature, shorten the sintering time and realize rapid one-time sintering at low temperature. In addition, wollastonite can also improve the mechanical properties of products, reduce cracks and warpage of products, increase glaze luster and improve the strength of embryos.




Wollastonite has important applications in many industries because of its excellent physical and chemical properties.
