Product Description
describe
Wollastonite powder is needle-shaped, with high whiteness and unique physical and chemical properties
characteristic. Widely used in ceramics, paints, coatings, plastics, rubber, chemicals, paper, welding electrodes,
Metallurgical mold slag, and as a substitute for asbestos, etc. Adding an appropriate amount of wollastonite powder to ceramic raw materials 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 the quality of the embryo. strength;
The chemical formula is CaSiO3

application
1. In the plastic industry, wollastonite powder not only plays a filling role, but also partially replaces asbestos and glass fiber as reinforcing materials.
2. In the rubber industry, natural wollastonite powder has a special needle-like structure, white, non-toxic, ultra-fine crushing, and surface modification is an ideal filler for rubber, which can not only reduce the production cost of rubber products, but also improve the quality of rubber. mechanical properties
3. In the paint industry, wollastonite powder is used as a filler in paints and paints, 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 reduce oil absorption. Quantity, enhance anti-corrosion ability.
Acicular wollastonite powder has good flatness, high color coverage, uniform distribution, and anti-ultraviolet
feature. Widely used in interior wall paint, exterior wall paint, special paint and latex paint.
4. In the paper industry, wollastonite powder can be used as a filler to combine with plant fibers to form paper composite fibers to replace part of 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.
