Q: What are the specific applications of wollastonite in coatings?: The use of needle like wollastonite 7, paint industry, excellent wollastonite powder coating used to paint some products, and some titanium dioxide instead of lithopone import P820 as a filler, can improve the coating leveling. And can greatly reduce the cost of paint;The use of needle like wollastonite 8, metallurgy and refractory industries, wollastonite unique physical characteristics - high melting point, making wollastonite become the most promising foreign experts in refractory materials;The use of needle like wollastonite 9, welding rod industry, wollastonite used in coating electrode, accelerate the melting rate, with energy saving, anti porosity, accelerated coating melting speed and so on;

Q: Can I use wollastonite mill or vertical mill for wollastonite powder?: Vertical mill is Raymond mill, the use of high manganese steel grinding roller grinding ring, will not destroy the structure of Wollastonite

Q: What is the difference between wollastonite powder and calcium carbonate?: Calcium carbonate is a kind of inorganic compounds, commonly known as CaCO: limestone, limestone, limestone, marble etc.. Main ingredients: calcite, is a kind of compound, chemical formula is CaCO, neutral, basically insoluble in water, soluble in hydrochloric acid. It is common on the earth substances exist in aragonite, calcite, chalk, limestone, marble, Shi Huihua rock, also is the main component of animal bones or shell.

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: The function of wollastonite powder: Wollastonite chemical composition close to the theoretical value, high purity, fine acicular structure, with low loss, harmful components (MnO, Fe203) content is low, the indicators better than similar domestic ore.

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: What's the use of wollastonite powder in coatings?How do you use it?: Coating wollastonite powder has a good reinforcing effect, which can improve the coating toughness and durability, and can keep the paint surface smooth and good gloss. But also improve the washing resistance and weathering resistance performance, but also can reduce the amount of oil paint and ink and alkali, has corrosion resistance. High quality color bright paint is obtained, and has good levelling property and aging resistance. The coatings can get better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. There is good coverage rate and adhesion.

Q: The difference between silica powder and wollastonite powder: Quartz sand is quartz quartz stone crushing processing. Quartz stone (quartz rock) also known as silica, silicate minerals is a hard texture, abrasion resistance, stable chemical properties. There are mainly quartz sandstone, quartzite and quartz in nature. Quartz sandstone is the consolidation of clastic rock, clastic quartz content more than 95%.Summarize yourself

Q: Use of Wollastonite: Wollastonite common powder and wollastonite needle powder are of different value. In addition to figuring out the main elements and the burning loss, the wollastonite in you can also see the particle shape in the powder state.

Q: Addition of needle like wollastonite in engineering plastics: Wollastonite is added to engineering plastics, which is called calcium plastic in the industry, because slaked lime is calcium hydroxide and lime is calcium carbonate. In order to increase the strength of the plastics, the calcined wollastonite is added.
