Product Description
Wollastonite
Introduction:
Wollastonite is a kind of multi-purpose industrial mineral, which plays an important role in modern industry because of its unique physical and chemical properties.In the ceramic production process, the appropriate addition of wollastonite can effectively reduce the temperature required for firing, shorten the firing cycle, and achieve rapid firing at a lower temperature, thus reducing energy consumption. This addition can also enhance the mechanical strength of ceramic products, reduce the problem of cracks and deformation caused by the firing process, while improving the smoothness and brightness of the glaze, enhance the overall fastness of the body, and these combined effects help significantly improve the qualified rate of the finished product. In addition, the inclusion of wollastonite helps to prevent cracks, small cracks, damage and enamel defects that may occur during the use of porcelain, ensuring the quality and durability of ceramic products.
Applications:
1, Ceramic Industry: ceramic raw materials by adding the right amount of wollastonite, can significantly reduce the firing temperature, shorten the time of firing to achieve a fast low-temperature firing, a large number of fuel savings, significantly reduce product costs. At the same time, improve the mechanical properties of products, reduce product cracks and stripes, improve product yield.
2, Painting and Coating Industry: in the paint with wollastonite filler or emulsion, you can get high-quality bright colors of paint, and have the coating and anti-aging properties. White wollastonite is a good raw material for high-quality white paint and soft pastel paint, easy to brush, the surface of a slide, has a high resistance to weathering.
3, Rubber and Plastics Industry: rubber and plastic can be done to strengthen the filler, with the thermosetting and thermoplastic resin and mold resin model, with good thermal shock resistance and enhance stability. Filled in the epoxy resin, before plastication has low water absorption, low dielectric constant and low viscosity, good performance.
4, Other Aspects: wollastonite can also be used for steelmaking slag, welding electrode coating, ceramic mold, grinding materials and grinding wheel production, paper filling agent, the production of white cement, manufacturing special electrical ceramics and other rare minerals raw material.
