Wollastonite

Q:Does exterior wall coating talcum powder replace wollastonite powder?: Can replace. Generally use talcum powder for exterior wall coating. Wollastonite is seldom used.

Q:How does the result of wollastonite analysis convert the grade of ore-forming stone?: Wollastonite ore is mainly composed of quartz and calcite (SiO2) (CaCO3), wollastonite (CaSiO3), the three major minerals by chemical analysis method to detect SiO2, CaO, so from the chemical analysis results is not apparent

Q:Latex paint, wollastonite powder can replace all heavy calcium carbonate?: Shuangfei powder is actually a "big white", if the brush on the wall, the surface cannot do other processing (putty, paint, etc.) must take this shovel back Shuangfei powder putty, can brush paint, otherwise, in this layer directly Shuangfei powder paint brush will peel a piece off. I have this lesson, I hope you will not be fooled again, repeat my mistakes.

Q:Does plastic modification add wollastonite to improve tearing properties?: The question is a bit vague. For example, PP+20% wollastonite modification, the tensile strength, modulus and other aspects will play a certain degree of improvement, if you say the tearing property is one thing with stretching it, then obviously improved.

Q:What are the specific applications of wollastonite in coatings?: The use of needle like wollastonite, 1 building materials industry: EPS thermal insulation mortar, interface agents, construction steel waterproof, ceramic tile, marble sealant, adhesive polystyrene board, calcium silicate board, powder coating, polymer mortar, anti cracking and impermeable concrete.

Q:Main characteristics of Wollastonite: Wollastonite is a chain metasilicate, and is a kind of fiber like needle. Because of its special crystal morphology, crystalline structure determines its properties. Wollastonite has good insulation, high whiteness, good dielectric properties and high heat resistance and weather resistance. Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on.

Q:What's the role of wollastonite in ceramic fiber products?: Wollastonite is a new type of industrial minerals, with its unique physical and chemical properties of mineralogy, and are widely used in ceramics, paint, rubber, metallurgy, casting, welding, abrasive, glass, mineral wool and other industrial sectors. Wollastonite is an ideal raw material for asbestos substitutes.With the continuous development of science and technology, the application research of wollastonite is more and more thorough. The improvement of the grinding method of wollastonite and the obtaining of ultra fine grade wollastonite powder will continue to develop new application fields of wollastonite.

Q:World resources of Wollastonite: The United States (NYCO, the earliest wollastonite manufacturer in the United States, New York and India have the resources, in the low-end market has extended to the foot of hunting, wollastonite application technology industry), India (Wolkem India Ltd.), Finland (Finland Nordkalk is one of the top five wollastonite manufacturer in the world was bought in 2002 by Finland. The group, Mexico and South Africa (Namaqua) Wollastonite (Pty.) Ltd. with the mineral resources aspect ratio, but the iron is relatively high, Namibia, Spain),

Q:Can wollastonite be certified by REACH?: Wollastonite does not need to be tested, but pre registration and registration are required.

Q:The difference between wollastonite and calcite: Wollastonite is a kind of silicate, because the heat resistance of wollastonite with acicular, fibrous crystal morphology and high whiteness, good dielectric properties and high so it is widely used in ceramics, chemical industry, metallurgy, construction, machinery, electronics, papermaking, automotive and other industries.
