product description
wollastonite
Wollastonite is a chain metasilicate, and it is also a fibrous and needle-like one. Due to its special crystal form and crystal structure, wollastonite has the characteristics of 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.

Adding an appropriate amount of wollastonite (medium-low grade) to the ceramic raw material can greatly reduce the firing temperature, shorten the firing time of the product, realize low-temperature rapid one-time firing, save a lot of fuel, and significantly reduce the firing cost. Product Cost. Since wollastonite products do not contain alkali metals, they have good electrical insulation properties, high impact strength and shape stability. This characteristic enables wollastonite to be used in fine ceramics and technical ceramics. Using wollastonite instead of white pigment in the raw material of glaze slurry can increase the luster of the glaze, reduce the viscosity of the glaze slurry and greatly reduce the cost. Wollastonite in ceramic products can prevent cracks, micro-cracks, breakage and enamel defects of porcelain. Wollastonite has linear thermal expansion characteristics, so it can reduce the deflection of the product. Adding 1% wollastonite to the glaze reduces thermal expansion enough to prevent the glaze from cracking when exposed to air. Application range: 1. Coating grade wollastonite powder has a good reinforcing effect, which can not only improve the toughness and durability of the coating, but also maintain the smoothness and good gloss of the coating surface. In addition, washability and wind resistance have been improved. It can also reduce the oil absorption of paints and inks and maintain alkalinity, and has the ability to resist corrosion. It is possible to obtain high-quality paints with high-quality color, good balance and anti-aging properties. Coatings allow for better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. Also has good coverage and adhesion. 2. Plastic rubber grade wollastonite has unique needle-like fibers, good insulation, wear resistance and high discount. It is a good filling material for plastic and rubber products. Features and properties: wollastonite powder can improve impact strength, enhance fluidity, improve tensile strength, impact strength, linear stretch and mold shrinkage. 3. Paper-making grade wollastonite Due to its unique needle-like structure, wollastonite mineral fiber can replace some plant fibers for the paper industry. The price of mineral fiber is much lower than that of bleached wood pulp. Using it to replace part of wood pulp can increase the strength of paper, save resources, reduce costs, and produce obvious economic, environmental and social benefits. Fibrous silicon belly is more suitable for replacing traditional fillers such as newsprint, offset paper, writing paper and other printed cultural papers. Enter the breakthrough point in the field of papermaking. Adding fiber wollastonite to paper will endow paper with some special properties due to its excellent properties such as good dimensional stability, heat resistance, chemical resistance, flame retardancy and electrical insulation. It can be used to produce special paper. And because the modified silica has a special fiber structure, it will not seriously affect the mechanical strength of the paper after being filled with pulp, so it can also be used for some paper types with high mechanical strength. strength requirements. In addition, this will also become the main research direction and development direction of fibrous wollastonite. After special processing technology, it can still maintain its unique needle-like structure, so the white paper with wollastonite powder is added to improve its whiteness, opacity (surface covering), flatness, smoothness, adaptability, reduction sex. Quantify the difference between the horizontal type and the wet deformation of the cardboard, improve the printing adaptability, and greatly reduce the amount of other raw materials, and reduce the cost of paper products in an all-round way. 4. Building material grade wollastonite is non-toxic, tasteless and non-radioactive. It has gradually replaced asbestos, which is harmful to human health, and has become a new raw material for environmentally friendly building materials in the new century. After special processing technology, its unique needle-like structure can be maintained, and the impact, bending strength and wear resistance of materials containing wollastonite powder, such as calcium silicate board and fireproof board, can be greatly improved. In the field of building materials, wollastonite stone will be more widely used.

5. Ceramic grade wollastonite Adding an appropriate amount of wollastonite powder to ceramic raw materials can greatly reduce the firing temperature, shorten the firing time, and achieve a fast firing. A lot of fuel is saved, and the product cost is greatly reduced; at the same time, the mechanical properties of the product are improved, the crack and temperature return of the product are reduced, the gloss of the glaze is increased, and the strength of the embryo body is increased, thereby improving the qualified rate of the product.
