Q:What's the use of wollastonite powder in coatings?How do you use it?
Ca3 Si3O9. Three triclinic. Usually flaky, radial or fibrous aggregates. White grayish. Glass luster, pearl luster. Cleavage surface hardness of 4? 0. parallel cleavage {100}, {001} parallel medium, two groups of angle is 74 degree. The cleavage surface density of 2? 78 ~ 91 g / cm 3. is mainly produced in contact metamorphic intrusive rocks and limestone belt as the main mineral component of skarn.
Q:Latex paint, wollastonite powder can replace all heavy calcium carbonate?
The main ingredient in putty is double fly powder, and also acts as filling agent. (the proportion of fly powder in water resistant putty is 70~75%).
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: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:Does exterior wall coating talcum powder replace wollastonite powder?
Talc in the paint can play a skeleton supporting role. The talc powder is in flake structure, the intermolecular attraction is great, and the adhesion of the coating is better.
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:Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?
Yes, this approach is imitation jade, general imitation Gao Pinyu, but is the use of stone powder and jade powder with glue condensation, compression, surface, and then polished can be
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:Excuse me, why is paste tile with stone powder, paste wall tiles with river sand?
The stone powder is generally much cheaper than river sand, and the amount of floor tile is large, and the stone powder is much more economical and convenient to draw materials.Note: cement paste is usually used as cement wall, not cement mortar. Only when the wall surface is poor, cement mortar can be used when leveling layer is used.
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.
