1. Product introduction

Wollastonite belongs to triclinic, crystal usually extends along Y-axis and becomes board shape, bacilliform or acicular. Pure wollastonite appears to be white, ivory-white light gray, light green or pink colour. Its appearance has vitreous luster.

Our company can manufacture many kinds of fine wollastonite powder, it is all manufactured by high quality raw materials. It has many good characteristics, such as granularity equality, homogeneous, high purity, endless catenulate, acicular crystallize, high whiteness, low ferrous, minimum S, P, low oil-absorption and etc.

Q:Conglomerate can not be exploited to destroy: Limestone (Limestone), commonly known as limestone, is a major component of calcite. Limestone is a sedimentary rock. Sometimes contain dolomite, clay mineral and detrital minerals, gray, gray, gray and black, yellow, red, brown red color, hardness is generally small, and the violent reaction of dilute hydrochloric acid. The structure is complex, with two kinds of clastic structure and grain structure. The clastic structure is mainly composed of particles, crystalline matrix and bright crystalline cement. Also known as debris particles, mainly in clastic, bioclastic and oolitic, micritic matrix is composed of calcium carbonate fines or crystal particle mortar, mostly less than 0.05 mm, microspar cements are chemical precipitates filling in porous rock particles in between, is larger in diameter than the calcite crystal particles of 0.01 mm the grain structure is; crystal particles by chemical and biological chemical deposition of.

Q:Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?: Yes, but they are not called jade articles, but they are called finished products, and the processing is usually pressed directly

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:Chemical TSP and wollastonite filled nylon do contrast to the good toughness: Chemical TSP and wollastonite filled nylon do contrast to the good toughness

Q:What are the specific applications of wollastonite in coatings?: The use of needle like wollastonite, 1 building materials industry: EPS thermal insulation mortar, interface agents, construction steel waterproof, ceramic tile, marble sealant, adhesive polystyrene board, calcium silicate board, powder coating, polymer mortar, anti cracking and impermeable concrete.

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:The difference between wollastonite and calcite: Wollastonite is a kind of silicate, because the heat resistance of wollastonite with acicular, fibrous crystal morphology and high whiteness, good dielectric properties and high so it is widely used in ceramics, chemical industry, metallurgy, construction, machinery, electronics, papermaking, automotive and other industries.

Q:Use of Wollastonite: Wollastonite has a wide range of uses, including construction, ceramics, coatings, paint, rubber and plastics industries.

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:What is the difference between wollastonite powder and calcium carbonate?: Calcium carbonate is a kind of inorganic compounds, commonly known as CaCO: limestone, limestone, limestone, marble etc.. Main ingredients: calcite, is a kind of compound, chemical formula is CaCO, neutral, basically insoluble in water, soluble in hydrochloric acid. It is common on the earth substances exist in aragonite, calcite, chalk, limestone, marble, Shi Huihua rock, also is the main component of animal bones or shell.
