CAS 1344-95-2 wollastonite powder 200 mesh, factory direct selling price mineral wollastonite

Wollastonite is a chain metasilicate, which is fibrous and needle-like. Since its special crystal morphology and crystal structure determine its performance, wollastonite has good insulation properties, and at the same time has high whiteness, good dielectric properties and high heat resistance and weather resistance. Because wollastonite is widely used in ceramics, chemical industry, metallurgy, papermaking, plastics, coatings and other fields.Coating grade wollastonite powderWith good reinforcing properties, it can not only improve the toughness and durability of the coating, but also keep the surface of the coating smooth and glossy. Moreover, it improves the scrub resistance and weather resistance, and can also reduce the oil absorption of paints and inks, maintain alkalinity, and have corrosion resistance. High-quality, colorful paints can be obtained with good leveling and anti-aging properties. Coatings allow for better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. It also has good coverage and adhesion.Plastic Rubber Grade WollastoniteIt has unique needle-like fibers, good insulation, wear resistance, and high refractive index. It is a good filling material for plastic and rubber products. Features and properties: Wollastonite powder can increase impact strength, enhance fluidity, improve tensile strength, impact strength, linear stretch and molding shrinkage.Friction grade wollastonite powderIt is a special needle-like structure with unique physical and mechanical properties of wollastonite. Greatly enhance the friction resistance and heat resistance of the finished product. When the product is filled inside, it can improve frictional flexibility and stability.Paper grade wollastonite powderAfter special processing technology, it can still maintain its unique needle-like structure, so that the whiteboard paper added with wollastonite powder can improve its whiteness, opacity (covering degree of the surface layer), flatness, smoothness, adaptability, and Reducing the lateral difference and wet deformation of the quantitative paperboard improves the printing adaptability, and can greatly reduce the use of other various raw materials, reducing the cost of paper products as a whole.Building material grade wollastonite powderIt has the advantages of non-toxic, tasteless, and non-radioactive, and gradually replaces 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, it can maintain the unique needle-like structure, which greatly improves the impact resistance, bending strength and wear resistance of calcium silicate board, fireproof board and other materials added with wollastonite needle powder. In the field of building materials, wollastonite will be more widely used!Ceramic grade wollastonite powderAdding an 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 firing. It saves a lot of fuel and significantly reduces the cost of the product; at the same time, it improves the mechanical properties of the product, reduces the crack and warpage of the product, increases the gloss of the glaze, improves the strength of the embryo body, and thus improves the qualified rate of the product.
