Wollastonite crystals fluoresce under ultraviolet radiation, and some also phosphorescent. It is mainly used in ceramics,
coatings, plastics, rubber and other industries.
Wollastonite powder has needle-like and fibrous crystal morphology, high whiteness and unique physical and chemical properties,
and is widely used in ceramics, paints, coatings, plastics, rubber, chemical industry, paper making, welding electrodes,
metallurgical protection slag and as asbestos substitutes. In the plastic industry, wollastonite powder not only plays a filling
role, but also partially replaces asbestos and glass fiber for reinforcing materials. At present, it has been applied in epoxy,
phenolic, thermosetting polyester, polyolefin and other plastics. Wollastonite powder is widely used in plastic products. As a plastic filler, it is mainly used to improve tensile strength and flexural strength and reduce costs. In the rubber industry,
natural wollastonite powder has a special needle-like structure, white and non-toxic. It is an ideal filler for rubber after
ultrafine crushing and surface modification. It can not only reduce the production cost of rubber products, but also improve the mechanical properties of rubber and endow rubber with special functions it does not have.
In the coating industry, wollastonite powder can be used as the filler of paint and coating, which can improve the physical and chemical properties of products, durability and weather resistance, reduce the gloss of paint, enhance the expansion ability of paint, reduce cracks, and also reduce the oil absorption and enhance the corrosion resistance. Wollastonite has bright color and high reflectivity, and is suitable for producing high-quality white paint and clear and transparent colored paint. The needle-like
wollastonite powder has good smoothness, high color coverage and uniform distribution, and has anti-ultraviolet characteristics.
It is widely used in interior wall coating, exterior wall coating, special coating and emulsion paint. The finer the particle
size, the higher the whiteness and PH value, the better the color and coating property of the paint, and the alkaline paint can be used as the anti-corrosion coating for steel and other metal equipment. In the paper industry, wollastonite powder can be used as filler and plant fiber to form paper composite fiber instead of some plant fiber. Reduce the amount of wood pulp, reduce the cost, improve the performance of the paper, improve the smoothness and opacity of the paper, improve the evenness of the paper, eliminate the static electricity of the paper, reduce the shrinkage of the paper, have good printability, and reduce the pollution emissions in the process of plant fiber pulping
