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:Silica powder and calcite powder have big difference
. 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:Does plastic modification add wollastonite to improve tearing properties?
However, the tearing properties of materials are generally applicable to films. If this is the case, I estimate that the tear properties of the film will not be improved by adding mineral fillers
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: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.
Q:World resources of Wollastonite
China is the world's largest producer of wollastonite, the largest consumer of wollastonite and the cheapest country for wollastonite resources. The distribution of resources is clear to everyone. Simple processing, market confusion, cheap exports, and then almost 10 - 20 times the price of imports.
Q:The difference between wollastonite and quartzite
Quartz sand is quartz quartz stone crushing processed. Rock (quartz), also known as silica, is a hard, abrasion resistant and chemically stable silicate mineral. In nature, quartz sandstone, quartzite and quartz quartz exist. Quartz sandstone is a consolidated clastic rock with a quartz content of more than 95%.
Q:Can I use wollastonite mill or vertical mill for wollastonite powder?
This problem is indeed a level, on the principle of grinding, Raymond machine or vertical mill is indeed not suitable for ultra-fine wollastonite crushing, but if the production of 325 purposes of coarse powder, it may also be used.
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.
