Product information:
For ceramics industry, appropriate Wollastonite in ceramic raw materials can achieve fast single firing inow temperature by reducing the sintering temperature and shortening the sinteringtime, which saves plenty of fuel and decreases production cost significantly. SinceWollastonite product is free of alkaline metal, it possesses high electrical insulation,high impact resistance and shape stability. With these properties, Wollastonitecan be applied in precision ceramics and craft ceramics. Filled in glaze material toimprove glaze luster and reduces the glaze mud viscosity as the replacement of whitepigment, which lowers the cost drastically. Filled in ceramics products to preventceramic from micro crack, damage and glaze defects. Furthermore, it can reduce thedeflection owning to its linear thermal expansion.
For Coating and paint, first rate Wollastonite as filler canbe applied in coating and paint to replace partly lithopone or titanium pigment &imported P820. The particle shape of Wollastonite serve as great suspending agentin the paint. lts soft & dispersed sediments can be used as reinforcing agent of cleantype coating. Due to low oil absorption capacity, high filling and lower consumptionof bonded materials, the cost of the paints is greatly decreased. With the advantageof slightly alkaline, fine spraying performance, surface uniform distribution,Wollastonite connect the acid medium pigment together, thus extremely suitable foipolyvinylacetate paint and steel coating by way of improving the corrosion resistanceWollastonite also serve as additive in waterborne coating, polyvinyl formal, primer,intermediate coating, oily coating, road marking paint, sound-deadening paint, fire-proof dope, etc. Wollastonite to replace asbestos in the use of self-cleaning paint, tobe applied as reinforcement agent in the use of asphalt paint.
