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?: There are issues related to REACH consulting Huace Mario, or leave your contact information, Huace swico is a listed company in the REACH industry background, is the absolute leader.

Q: Excuse me, why is paste tile with stone powder, paste wall tiles with river sand?: Put tiles on the ground, does not appear to be falling, and floor tiles, is to put the thickness of 5 cm above the powder and cement mixture of flat ground, large amount of material, on the ground, it is easy to compaction, cement and powder with cohesive force as long as appropriate, can satisfy the requirement of use, floor tiles posted above in the leveling layer, floor tiles will put bricks before the water wet, and then glued only cement paste, is affixed to the above, it is ensured that the combination of brick and cement, stone powder mixture firmness.

Q: The difference between silica powder and wollastonite powder: Wollastonite is a chain metasilicate, and is a kind of fiber like needle shaped

Q: The difference between wollastonite and calcite: Calcite powder is commonly used in powdered inorganic filler with high chemical purity, inert, easy chemical reaction, good thermal stability, high whiteness, low oil absorption, soft, dry, no crystal water, low hardness, abrasion value, non-toxic, tasteless, odorless, dispersion, etc.. Widely used in plastics, rubber, paper making, coating, feed, medicine, daily chemicals, glass, ceramics and other fields.

Q: What is the difference between wollastonite powder and talc powder?: The main component of talc is talc, hydrated magnesium silicate, and the formula is Mg3[Si4O10] (OH) 2. This product is magnesium silicate mineral, talc group talc, the main component is magnesium silicate hydrate, after grinding, treated with hydrochloric acid, washed, dried. Talc lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good gloss, strong adsorption capacity, excellent physical and chemical properties, for the purpose of cosmetic grade (1) (HZ): used for various skin powder, cosmetic powder, talcum powder etc..

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: 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: 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).

Q: Does plastic modification add wollastonite to improve tearing properties?: The question is a bit vague. For example, PP+20% wollastonite modification, the tensile strength, modulus and other aspects will play a certain degree of improvement, if you say the tearing property is one thing with stretching it, then obviously improved.
