Wollastonite,powder

The crystals of wollastonite fluoresce when irradiated with ultraviolet light, and also phosphorescent. used in ceramics, coatings, plastics, rubber and other industries.
Wollastonite powder has needle-like, fibrous crystal form and high whiteness and unique physical and chemical properties, and is used in ceramics, paints, coatings, plastics, rubber, chemicals, papermaking, welding rods, metallurgical protective slag and as a substitute for asbestos.
In the plastics industry, wollastonite powder not only plays a filling role, but also replaces asbestos and glass fibers for reinforcing materials. At present, it has been applied in various plastics such as epoxy, phenolic, thermosetting polyester, polyolefin and so on. Wollastonite powder is used in a large number of plastics for deep processing products. It is used as a plastic filler, used to improve tensile strength and flexural strength, reducing costs.
In the rubber industry, natural wollastonite powder has a special needle structure, white, non-toxic, after ultra-fine crushing, surface modification is the ideal filler for rubber, not only can reduce the production cost of rubber products, but also can improve the mechanical properties of rubber, giving rubber itself a special function that it does not have.
In the coating industry, wollastonite powder as a paint, coating filler, can improve the physical and chemical properties of the product, durability weather resistance, reduce the gloss of the paint, enhance the expansion of the paint, reduce cracks, but also can reduce the amount of oil absorption, enhance the ability to resist corrosion. Wollastonite has a bright color and high reflectivity, which is suitable for the production of high-quality white paint and clear and transparent colored paint. Needle-shaped wollastonite powder has good flat light, high color coverage and uniform distribution, and has the characteristics of ultraviolet resistance. It is used in interior wall coatings, exterior coatings, special coatings and latex paints. The particle size is ultra-fine, the whiteness and PH value are higher, the better the paint color and applicability, and the paint alkaline can be used as an anti-corrosion coating for metal equipment such as steel.
In the paper industry, wollastonite powder can be used as a filler and plant fiber composite into papermaking composite fibers instead of some plant fibers. Reduce the amount of wood pulp, reduce costs, improve paper performance, improve the smoothness of paper products, opacity, improve the uniformity of paper products, drop static electricity of paper, paper shrinkage rate is less, printability is good, and can reduce pollution emissions in the pulping process of plant fibers.
