Wollastonite is chemically a Calcium MetaSilicate (CaSiO3),Wollastonite with dense shaped ceramic structure can improve the mechanical strength, reduce the wet expansion coefficient, improve the bodys strength and molding quality, and reduce the sintering temperature so that rapid sintering in low temperatures, the purpose of energy saving and efficiency can be achieved. In the glaze making industry, wollastonite can improve the whiteness and fluidity of glaze, and reduce the defects of products. Wollastonite can be used to produce all kinds of electroceramics, architectural porcelain/ceramics, daily-use ceramics and brake pads, etc. Nearly half of the world's annual output amount of wollastonite is used in ceramics as the largest production field.Wollastonite in China is mainly used in glazed bricks and ceramic bodies, copying more than 50% of the total consumption amount of wollastonite.
Description: Wollastonite has bright color and high reflectivity, which could be suitable for the production of high-quality white paints and clear transparent paints.wollastonite is a good additive with higher fraction of color coverage and homogeneous distribution. Based on its UV resistance, it is widely used in interior wall paints, exterior wall paints, special paint (especially fireproof paint) and latex paints. Wollastonite powder which can partly replace titanium dioxide to produce paint coating can not only improve the color of products, improve the gloss of the paint, enhance the anti-tensile ability of the paint, reduce the crack, but also can reduce the oil absorption and enhance the anti-corrosion ability. The finer particle size, higher whiteness and pH value can greatly improve the color and coating property of the paints, which can be helpful to produce anticorrosive coating for metal equipment such as steel pieces. Wollastonite can also be used as the filler of paint coating to improve the physical and chemical properties, durability and weather resistance and reduce the fracture and aging of the paint. The quality requirements of wollastonite in paint coatings are: SiO2 49%min, CaO 45%min, Fe2O3 0.2%, 325 mesh, mineral powder oil absorption amount is 20-25g/100g, water soluble matter 0.5%, water extraction pH value is 7-9, whiteness 90%.
Applications: Specific wollastonite powder can be used to be the substitute for lithopone, part of titanium dioxide, white carbon black, light calcium and clay in different finished rubber products. The application results show that wollastonite can improve the covering ability of white colorant and play a role in whitening.It can replace a large quantity of titanium dioxide, clay and lithopone in the adhesives with light colors, which can strengthen the qualities of the products and reduce the cost.The combination of wollastonite and coupling agents can improve the properties of rubber compounds and expand its application range. Our advantages: 1.lower Fe content 2.Lower loss on ignition (LOI) 3.Fewer surface defects 4.Improved shrinkage control 5.Higher impact strength 6.Faster drying times 7.higher whiteness
