1. The light calcium carbonate can be used as a leavening agent, flour treatment agent and anticaking agent, acidity regulator, nutrition enhancer, curing agent, etc. Regulations in China can be used in all kinds of food to add softener and gum rubber base, according to the GMP. Can also be used in flour improver, maximum amount is 0.03%; Powder from 18 to 7.5 g/kg; Soy, 4 ~ 20 g/kg of flour, Soft drinks 0.4 ~ 3.4 g/kg; Lotus root starch 6 ~ 8 g/kg; Ready-to-eat breakfast cereal products 2 ~ 7 g/kg. The FDA (184.1192, 2000) do not restrictive provisions, in accordance with the GMP. When using this product as a leavening agent more used together with other varieties, with sodium bicarbonate, alum, etc by raising agent, when they are heated slowly release carbon dioxide, uniform, fine food of bulk body, can improve the quality of the pastry, bread, biscuits. In addition to strengthen the effect of calcium, calcium carbonate particles the smaller easily absorbed. In Japan, light calcium carbonate used as leavening agent, the dosage was 1% in common food.2. Used as feed nutrition enhancer.3. The calcium carbonate whisker was used in the rubber industry and plastic industry, the earliest one of the largest filling agent dosage. In the rubber industry, widely used in rubber hose, rubber sheet, tape, rubber shoes and medical products, good packing is to reduce product cost. In the plastics industry, mainly used for soft PVC compound, plastisol and glass fiber reinforced polyester composites, etc., such as wire skin, artificial leather, and other pressure out of rolled products, general dosage for the 20 or so. Also has a large number of application in plastic materials, such as hard PVC pipe, plate, etc. In addition, this product is widely used in papermaking, coating, printing ink industry, daily chemical products.4. Compared with general granular calcium carbonate, calcium carbonate whisker showed remarkable enhancement, toughening effect. Calcium carbonate whisker reinforced plastic, rubber. As used in polyamide, thermoplastic polyester, polycarbonate, ABS, PP resin, such as enhanced modifier, while reducing costs, also can improve the bending strength of the product, dimensional stability and thermal stability. In papermaking industry as a high-grade paper packing, this paper can be used as a flame retardant paper used for interior decoration, etc. Calcium carbonate whisker non-toxic, is an ideal substitute, asbestos can be used as a friction material instead of asbestos, and manufacturing car brake friction materials, etc.5. Of the filling material of rubber, can make the rubber color luster, high elongation, tensile strength, wear-resisting performance is good. Also used for artificial leather, wire, PVC, paint, ink and paper and other industrial packing. When used in the production of microporous rubber, can make its foam evenly.6. Used for plastic, paper, rubber, paint, printing ink, such as white filler, as one of the most widely used filler. Its price is low, sources, relative density is small, besides has the incremental effect, still can improve the processing performance and product performance. In the manufacture of adhesive, can be used as a sealant epoxy glue, nylon, neoprene sealant of filling agent, etc. In some soft polyvinyl chloride (PVC), a heat stable effect, can reduce the dosage of heat stabilizer. Used for PVC paste can be used as a viscosity regulator. For wire wrapping, artificial leather, etc can improve the color stability of the products. In daily chemical industry raw materials such as a manufacturing dentifrices. Medicine, used for gastric and duodenal ulcer disease antacids and acidosis antidote. Agriculture used as cows feed additives and antibacterial agent. In the industrial waste gas treatment used to remove sulfur emissions of SO2. In the water treatment for industrial waste water neutralization agent and flocculant. Felt used for sticking prevention in production. Used to eliminate the acidity in wine brewing, but also used for manufacturing a match, pencil, crayon, insulation materials, welding electrode and so on packing.7. Used in the manufacture of powder, powder, liquid powder, rouge, such as raw material, the powder class cosmetics used as fragrance mixture, abrasive is mainly used in toothpaste, toothpaste with hard abrasive.
