White wollastonite for ceramic industrial wollastonite powder
Product Description
The chemical formula is CaSiO3
Wollastonite powder has needle shape, high whiteness and unique physical and chemical properties.Widely used in ceramics, paints, coatings, plastics, rubber, chemicals, papermaking, welding electrodes, metallurgical mold flux, and as a substitute for asbestos.Adding an appropriate amount of wollastonite powder to the ceramic raw materials can greatly reduce the firing temperature, shorten the firing time, realize rapid firing at low temperature, save a lot of fuel, reduce product cost, reduce cracks and warpage, increase luster, 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, ultra-fine grinding, and 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 industry, Wollastonite powder is used as a filler for paints and coatings, which can improve the physical and chemical properties, durability and weather resistance of products, reduce the gloss of paints, enhance the expansion capacity of coatings, reduce cracks, and can also reduce oil absorption, Enhance anticorrosion ability.
The acicular wollastonite powder has good flatness, high color coverage, uniform distribution and UV resistance. Widely used in interior wall coatings, exterior wall coatings, special coatings and latex paints.
4. Inpaper industry, Wollastonite powder can be used as filler to be compounded with plant fiber to form composite fiber for papermaking, replacing part of plant fiber. Reduce the amount of wood pulp, reduce costs, improve the performance of paper products, increase the smoothness and opacity of paper products, improve the uniformity of paper products, eliminate paper static, reduce paper shrinkage, good printability, reduce plant pollution emissions in fibers during the pulping process.
