TSP Industrial Grade

Coarse whiting, calcite powder, is short for heavy calcium carbonate, is made of natural carbonate minerals such as calcite, marble, chopped lime stone mill. Is a common inorganic filler powder with high chemical purity, large inertia, chemical reaction, good thermal stability, does not decompose under 400 ℃, high whiteness, low oil absorption rate, low refractive index, soft, dry and without water of crystallization, low hardness abrasion value of small, non-toxic, tasteless, odourless, good dispersion, etc. According to the need for different particle size requirements of ordinary coarse whiting powder, superfine heavy calcium carbonate, wet grinding superfine heavy calcium carbonate, ultra-fine surface modification of calcium carbonate.

Heavy calcium Carbonate GCC (Grinding Calcite Carbonate) in Calcite, chalk, marble ore as raw material, such as the mechanical crushing method in the production of calcium Carbonate powder. According to the particle size (D97, mm) can be divided into coarse powder and fine heavy calcium carbonate powder (D97 > 10 mm) and superfine heavy calcium carbonate (D97 10 mm or less); According to whether the surface modification can be divided into heavy calcium carbonate (hereinafter referred to as coarse whiting) and the activity of heavy calcium carbonate (hereinafter referred to as active coarse whiting); Also active calcium carbonate can be subdivided into active coarse whiting powder and super XiHuoXing coarse whiting powder.

application

Calcium carbonate has been widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, paint, paint, printing ink, sealing wax, putty, putty, blanket packaging, medicine, food, such as chewing gum, chocolate, feed, its functions are: to increase volume, reduce cost, improve the processing performance, such as adjusting the viscosity and rheological properties, vulcanization properties), improve the dimensional stability, reinforcing or half reinforcement, improve printing performance, improve the physical properties (such as heat resistance, light resistance, abrasion resistance, flame retardancy, whiteness, glossiness), etc.

The application of coating industry

In the paint and plastic industry, "coarse whiting is calcite powder," is short for "heavy calcium carbonate, active ingredient is heavy calcium carbonate, heavy calcium carbonate is also referred to as" coarse whiting ", usually used as a filler, widely used in artificial floor tile, rubber, plastic, papermaking, coating, paint, printing ink, cable, construction supplies, food, medicine, daily chemical industry such as textile, feed, toothpaste, as a filling agent rise to increase the volume of products, reduce the production cost.

The application of chemical fertilizer industry

In the chemical fertilizer industry, also referred to as "heavy calcium superphosphate (zhong)" "coarse whiting" (TSP), chemical formula: Ca (H2PO4) 2. And referred to as "universal" calcium superphosphate of main component is calcium dihydrogen phosphate and plaster, chemical formula: Ca (H2PO4) 2 and CaSO4.

Alias: coarse whiting; Triple superphosphate: three material calcium superphosphate

English name: Triple superphosphate (TSP)

Physical and chemical properties: appearance are pale or dark brown, is a high concentration and acidic phosphate fertilizer, mostly water soluble, and a small amount of calcium sulphate, iron phosphate, aluminum phosphate, magnesium phosphate is a free phosphoric acid and water, etc.

Agrochemical properties: coarse whiting excluding ferric sulfate, aluminium sulfate, almost all is composed of a calcium phosphate, does not occur in the soil degradation of phosphate. In the alkaline soil and crops like sulfur, coarse whiting effect than calcium. The rest of the similar to general calcium.
