2. In the plastics industry, wollastonite powder not only plays a filling role, but can also partially replace asbestos and glass fiber for reinforcing materials.
3. Wollastonite can replace titanium dioxide, clay and lithopone in large quantities in light-colored rubber, play a certain reinforcing role, and improve the covering ability of white colorants. Play a whitening effect. After wollastonite is organically modified, not only its surface is lipophilic, but also because the treatment agent sodium oleate molecule has double bonds, it can participate in vulcanization, enhance cross-linking, and greatly improve the reinforcing effect.
4. In the coating industry, wollastonite powder is used as a filler for paints and coatings, which can improve the physical and chemical properties of the product, durability and weather resistance, 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.
The acicular wollastonite powder has good flatness, high color coverage and uniform distribution, and has anti-ultraviolet characteristics. It is widely used in interior wall coatings, exterior wall coatings, special coatings and latex paints.
5. In the paper industry, wollastonite powder can be used as a filler and plant fiber to compound into a paper-making composite fiber to replace part of the 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 electricity, reduce paper shrinkage, good printability, and reduce plants Pollution emissions during the fiber pulping process.
