- 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: What are the surface modification methods and processes of wollastonite?
- Wollastonite is a calcium metasilicate mineral, often white and greyish white, with a glassy luster to a pearly luster. Because of its non-toxic, chemical corrosion resistance, thermal stability and dimensional stability, good mechanical and electrical properties, as well as strengthening and other advantages, it is widely used as reinforced fillers for polymer matrix composites.
- 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: What's the role of wollastonite in ceramic fiber products?
- Wollastonite application in the ceramic industry: it can produce glazed tile, sanitary ware, daily porcelain, fine arts porcelain, power porcelain, high frequency low consumption electric porcelain, chemical ceramics, glaze, pigment, glass, mould, etc.. The main role for wollastonite in ceramic industry are: 1, reduce the sintering temperature of 2.; shorten the firing period; 3. increase of body and burning body temperature; 4. easy molding; 5. reduce blank firing shrinkage; 6. to reduce the moisture expansion of bodies; 7. decrease of glass phase viscosity.
- Q: The difference between silica powder and wollastonite powder
- Due to its special crystal morphology crystalline structure determines the properties of wollastonite, has good insulation, and has high whiteness, good dielectric properties and high heat resistance and weatherability. Because wollastonite is widely used in ceramics, chemical industry, metallurgy, papermaking, plastic, paint and other fields.
- 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: Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?
- This identification method has a variety of jade, can be as light but not dazzling, let the light, the permeability is insufficient, it can be across the glass, if it is true, draw the engraving is not false, but also by the method of distinguishing rubber jade.
- Q: Salt bath and bath salt is what?
- Salt bath and bath salt there is no mineral salt.
- Q: What is the best way to dig a conglomerate?
- The conglomerate is defined by more than 50% particle diameter greater than 2 mm is composed of clastic rock. The degree of rounding better gravel cementation and become conglomerate; with the edges of the corner by gravel, gravel and cement as breccia.
- 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.
