Calcium metasilicate

Details:

Friction Material Wollastonite can be applied to brake pads, linings, clutch, valve, pulleys,ect. Benefits of using wollastonite in a friction formulation include improved friction stability, reduction or elimination of cracking, greatly enhance the rub-resistance and heat-resistance of the ultimated product, improved physical and mechanical properties. It is also a partial/full replacement for other fiber materials that can reduce the production cost and improve the value of the products. 2、Construction With the advantages of nonpoisonous, tasteless, nonradiation,etc, wollastonite become to replace the similar building materials which are harmful to humans. Added acicular powder wollastonite, the mechanical property of the calcium silicate board、fire-resistant board and other construction materials are all obviously improved such as impact resistance, flexural stength, wear-resistant strength, ect. It can also be used in other constuction areas, for example: white cement and architecture putty, ect. 3、Paints and Coatings Due to its high cohesion, add wollastonite in coatings can make the paint film have no cracks, improve the machanical strength and weatherability of coatings,ect. After composite of physics &chemistry, the wollastonite has lower oil-absorption, higher dispersion, better flwability, strong UV stability and anti-aging ability, and also improve the property of paint film such as wearability, scattering power, hiding power and antiseptic property. Metallurgical It has stable chemical property and low loss on ignition after physics & chemistry composited, also its component ratio is within the basicity range which metallurgical fluxes needed. It can reduce slag type, simplify production process, make the metallurgical fluxes have good thermal stability, to the effect of thermal insulation, isolate air, lubricate ingot blank and impove the heat transfer property. Our wollastonite have low contents of Al2O3、S、P, low melting point and low viscosity, so it can enhance the property of absorbing Al2O3 and other impurities.Also, According to the special requirements of customers, we can produce slag-adjustment materials in different alkalinity. Welding In the electrode coating, with the advantage of energy-saving,
