Q: Can titanium, barium sulfate, calcium carbonate, wollastonite powder and talcum powder be transported by ordinary vehicles?: The dust of the road: now anti-dust masks must implement the GB2626-2006 standard. Dust masks are divided into three grades: KN100, KN95 and KN90. Among them, KN100 can reach nearly 100% (99.97% of above) dust protection effect. For large particles, the KN95 grade can be used. The protection effect depends on 2 aspects. One is the filtration efficiency of filter cotton. The two is the leakage rate of the mask and face.

Q: What are the specific applications of wollastonite in coatings?: The use of needle like wollastonite 6, insulation, insulation materials, glass products and polymer composite materials, etc., can improve the product strength, hardness, and heat resistance, bending resistance, corrosion resistance.

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 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: Can wollastonite be certified by REACH?: In addition, you need to know whether you are talking about whether the wollastonite is a natural substance or not. If it is a natural mineral, there is no need to deal with REACH. It can be exempted.

Q: What's the use of wollastonite powder in coatings?How do you use it?: Also found in certain deep metamorphic rocks: used as raw materials or fillers for paper making, ceramics, cement, rubber, plastics, gas filtration materials and heat insulation materials, metallurgical fluxes, etc.

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: Main characteristics of Wollastonite: The chemical formula of wollastonite is CaSiO3, the structural formula is Ca3[Si3O9], and the theoretical chemical components are CaO 48.25% and SiO2 51.75%. In nature, pure wollastonite is rare, and in its formation, Ca is sometimes replaced by Fe, Mn, Ti, Sr plasma, and is isomorphous, with a small amount of Al and trace amounts of K and Na.

Q: Latex paint, wollastonite powder can replace all heavy calcium carbonate?: Shuangfei powder is also called the "big white", the main component is calcium carbonate, also referred to as "tsp". Is widely used in ceramics, rubber, plastics, paper, paint, paint, ink, cable, food, medicine, textile, feed, toothpaste and other daily chemical industry as a filler to increase the volume of products, reduce the production cost.

Q: Salt bath and bath salt is what?: Mineral salt is a salt, which contains many minerals, these minerals beneficial to human health, easy to absorb, containing silicate (SiO4) generic minerals (including silicon containing salt, other such as partial Portland, wollastonite CaSiO3 case). Can be regarded as a combination of SiO2 with other oxides (mostly metal oxides).
