Wollastonite Powder-Grade B Ceramics Grad


Q:The difference between silica powder and wollastonite powder
Wollastonite is a chain metasilicate, and is a kind of fiber like needle shaped
Q:Can titanium, barium sulfate, calcium carbonate, wollastonite powder and talcum powder be transported by ordinary vehicles?
Therefore, masks must be divided into size, size, masks and facial leakage rate varies from person to person.The dust of the road: scientific selection of certified GB2626-2006 standard anti-dust masks, contribute to the prevention of lung injury.1, choose double mask type. Disposable respirators are not suitable for long-term or occupational protection due to high leak rate.2, select the KN100 level. High dust environment, low protection rate will lead to physical damage.3, choose silicone mask, the service life is relatively long, soft and comfortable. Wear for a long time, it is not easy to cause allergic reactions. A mask with a high hardness can easily cause a facial impression.4, mask size, this is extremely important. It is not recommended to buy so-called universal models of masks that are prone to leakage.5, mask covered with nose and mouth, covering the mouth and nose and jaw 2 kinds, it is recommended to use the latter, relatively comfortable.6, it is recommended to choose breathing smooth mask. Some masks use double filter cotton + double filter surface design, relatively smooth breathing, and long service life.
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:What is the difference between wollastonite powder and talc powder?
The main component of wollastonite is calcium silicate, Ca3 (Si3O9), appearance: wollastonite white gray, red, flaky microstrip, radial or fibrous aggregates, three triclinic, shiny glass, pearl luster cleavage mask. Mainly used in ceramics, coatings, plastics, rubber and other industries.
Q:What is the difference between wollastonite powder and calcium carbonate?
Wollastonite is calcium silicate and calcium carbonate is carbonate.
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:The function of wollastonite powder
Wollastonite after finishing has the characteristics of high aspect ratio (10:1-15:1), high whiteness and so on. Has been widely used in plastics, rubber, coatings, ceramics, friction materials, insulation materials, building materials and other industries.
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: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: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;
