White wollastonite industrial grade wollastonite powder for ceramics
Product Description
The chemical formula is CaSiO3
Wollastonite powder is needle-shaped, with high whiteness and unique physical and chemical properties.Widely used in ceramics, paints, coatings, plastics, rubber, chemicals, papermaking, welding electrodes, metallurgical mold slag, asbestos substitutes, etc.Adding an appropriate amount of wollastonite powder to the ceramic raw material can greatly reduce the firing temperature, shorten the firing time, realize low-temperature fast firing, save a lot of fuel, reduce product costs, reduce cracks and warping, increase gloss, and improve embryo physical strength

application
1. inplastic industry, Wollastonite powder not only plays a filling role, but also can partially replace asbestos and glass fiber as reinforcing materials.
2. inrubber industry, natural wollastonite powder has a special needle-like structure, white, non-toxic, ultrafine pulverization, surface modification is an ideal filler for rubber, which can not only reduce the production cost of rubber products, but also improve the mechanical properties of rubber
3. inPaint industryWollastonite powder is used as a filler in paints and coatings, which can improve the physical and chemical properties, durability and weather resistance of the product, reduce the gloss of the paint, enhance the expansion ability of the coating, reduce cracks, and can also reduce oil absorption and enhance anti-corrosion ability.
Acicular wollastonite powder has good flatness, high color coverage, uniform distribution, and anti-ultraviolet properties. Widely used in interior wall paint, exterior wall paint, special paint and latex paint.
4. inpaper industry, Wollastonite powder can be used as a filler to be combined with plant fibers to form paper-making composite fibers, replacing some plant fibers. Reduce the amount of wood pulp, reduce the cost, improve the performance of paper products, increase the smoothness and opacity of paper products, improve the uniformity of paper products, eliminate paper static electricity, reduce paper shrinkage, good printing suitability, and reduce plant pollution emissions in the fiber system in the pulping process.
