Wollastonite with acicular, fibrous crystal morphology and higher whiteness and unique physical and chemical properties, widely used in ceramics, paint, coatings, plastics, rubber, chemical industry, papermaking, welding electrodes, metallurgical protective slag as well as asbestos substitute.
In the plastics industry in wollastonite powder not only to fill the role and can also replace asbestos and glass fiber for reinforcing material. At present, it has been in the epoxy, phenolic, thermosetting polyester, polyolefin and other plastics to obtain the application. Wollastonite deep-processing products is widely used in plastics. It is used as a plastic filler, mainly used to improve the tensile strength and flexural strength, reduce costs.
In the rubber industry, natural wollastonite powder with needle like structure, white, non-toxic, after superfine grinding and surface modification is ideal filler of rubber can not only reduce the cost of production of rubber products and improve the mechanical properties of rubber, give the rubber itself not some special functions.
In the paint industry, wollastonite powder paint, paint filler, can improve the physical and chemical properties of products, weatherability and lasting, reduce gloss paint, coating to enhance the ability of expansion, to reduce the cracks, but also can reduce the amount of oil, to enhance the ability of anti corruption. Wollastonite, bright color, high reflectivity, suitable for the production of high quality white paint and transparent colored paint. Acicular wollastonite powder Plano good color, high coverage and uniform distribution, with anti UV properties. Widely used in interior wall coatings, exterior wall coatings, special coatings and emulsion coatings. Ultrafine grain size, the higher the degree of whiteness, the higher the pH value, paint color and coating of the better, and the paint can be used to make steel and other metal equipment for corrosion protection.
In the paper industry, wollastonite as filler and plant fiber composite paper composite fiber to replace part of plant fiber. Reduce the amount of wood pulp, reduce costs, improve the performance of paper products, improve the smoothness of paper products, opacity, improve paper products of uniform, eliminate paper electrostatic, paper product shrinkage rate less, printability and reduce pollution emissions in the process of plant fiber pulping.
