Raw Ceramic Material Wollastonite for Glazes

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

Product Description

Applications:

1.Coating grade wollastonite powder has a good reinforcing property, which can not only improve the toughness and durability of the coating, but also keep the coating surface flat and good gloss. And improve the resistance to washing and weathering performance, but also reduce the amount of paint and ink oil absorption and maintain alkaline, with corrosion resistance. High quality bright color coatings can be obtained, and has good coating uniformity and aging resistance. The coating can get better mechanical strength, increase durability, enhance adhesion and corrosion resistance. And good coverage, adhesion.

2.Plastic rubber grade wolverite has a unique needle-like fiber, with good insulation, wear resistance, and high refractive index. Is plastic, rubber products better filling material. Features and properties: Wollastonite powder can improve impact strength, enhance fluidity and improve tensile strength, impact strength, linear tensile and die shrinkage.

3.Friction grade wollastonite powder is a special needle-like structure, and wollastonite has unique physical and mechanical efficiency. Greatly enhance the friction resistance and heat resistance of the finished product. When the product is filled into the inside, the friction flexibility and stability can be improved.

4.Papermaking grade silicon ash powder after special processing technology can still maintain its unique acicular structure, make the powder added silicon is gray of white board paper, increase the whiteness and opacity (surface cover degrees), flatness, smoothness, adaptability, less quantitative difference of horizontal and cardboard wet deformation, improve printing adaptability, and can greatly reduce the other usage of all kinds of materials, Reduce the cost of paper products in general.

5.Building materials grade wollastonite powder is a kind of non-toxic, tasteless, non-radioactive and other advantages gradually replaced the harmful asbestos to human health, become a new material of environmental protection building materials in the new century. After the special processing technology, it can still maintain its unique needle-like structure, so that the impact resistance, bending strength and wear resistance of silicon calcium plate and fire board materials with wollastonite needle-like powder are greatly improved. In the field of building materials, wollastonite will be more widely used!

6.Adding appropriate amount of wollastonite powder to ceramic raw materials can greatly reduce the firing temperature, shorten the firing time, and achieve low temperature and rapid one-time firing. A large amount of fuel saving, significantly reduce the cost of products; At the same time, improve the mechanical properties of the product, reduce the crack and warping of the product, increase the glaze gloss, improve the strength of the embryo body, and then improve the qualified rate of the product.
