Carbonate Calcium Usage and Function.

Calcium carbonate is a substance widely used in various fields. In architectural coatings, calcium carbonate is used in large quantities in water-based coatings because it is white, hydrophilic, inexpensive, and enhances the deposition and penetration of primers on the surface of the substrate.

In the medical field, calcium carbonate is used as a drug carrier and additive to improve the stability and efficacy of drugs and reduce adverse reactions, as well as for the treatment of hyperacidity and the prevention of stones.

In the field of environmental protection, calcium carbonate is used as an adsorbent and precipitant to remove harmful substances in water, reduce the hardness of water and improve water quality, and it can also be used in the fields of waste gas treatment and soil remediation.

In addition, calcium carbonate is widely used in ceramics, glass, rubber, medicine, pigment, paint and other fields.

Uses of Carbonate Calcium.

It can be used as filler in rubber, plastic, paper making, coating and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production.

It can also be used as neutralizer of industrial wastewater, acidifier for gastric and duodenal ulcer disease, antidote for acidosis, sulfur dioxide eliminator in sulfur dioxide-containing exhaust gas, feed additive for dairy cows and anti-sticking agent for linoleum. It can also be used as raw materials for tooth powder, toothpaste and other cosmetics.

It can be used as filler in rubber, plastic, paper making, putty, primer, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production.

It can also be used as neutralizer of industrial wastewater, acidifier for gastric and duodenal ulcer disease, antidote for acidosis, sulfur dioxide eliminator in sulfur dioxide-containing exhaust gas, feed additive for dairy cattle and anti-sticking agent for linoleum. It can also be used as raw materials for tooth powder, toothpaste and other cosmetics.

According to the different fineness of crushing, it is industrially divided into four different specifications: single-fly, double-fly, triple-fly and quadruple-fly, which are respectively used in various industrial sectors.

Single fly powder is used for the production of anhydrous calcium chloride, is an auxiliary raw material for the production of sodium dichromate, is also the main raw material for the production of glass and cement, in addition, it is also used for construction materials and poultry feed, etc.; double fly powder is the raw material for the production of anhydrous calcium chloride and glass, etc., it is also the white filler for rubber and paint, and is also used for construction materials, etc.; three fly powder can be used as a filler for plastics, paints and varnishes; four fly powder can be used as a filler for the insulating layer of wires, a filler for rubber molding products, and a filler for the insulation layer of rubber. It can be used as filler of wire insulation layer, rubber molding products and asphalt felt.

Used in rubber, it can effectively improve the compression strength, abrasion resistance and extrusion strength of rubber products; used in plastic products, it can make the surface of the products smooth and clean, and replace part of the PVC resin dosage; used in papermaking, it can improve the gloss, whiteness and opacity of the coated paper, and improve the suitability of the paper for printing, and it is widely used in matte paper, charcoal-free rewritable paper, coated paper with paper dosage and white cardboard, and so on.

Characteristic of Carbonate Calcium.

Product method of Bulk Carbonate Calcium Powder.

Carbonization method will be selected limestone crushed to 50 ~ 150mm, smokeless (white) coal particle size of 38 ~ 50mm. coal and limestone in the ratio of 1:8 ~ 1:11 into the furnace, calcined at 900 ~ 1100 ° C, so that the limestone decomposed into quicklime and carbon dioxide at high temperatures. With 3～5 times water, it is dissolved by digestion at 90℃ for 1.5～2.0h to get lime milk with a concentration of 10～18°Bé, which is filtered and removed for carbonization.

Carbon dioxide is sent to the carbonization tower after washing and purification, the concentration of 30% ~ 40%, carbonization temperature of 60 ~ 70 ℃, carbonization pressure of 0.078Mpa, carbonization endpoint control pH value of 7. Calcium carbonate slurry by centrifugal dewatering (moisture content of 32% ~ 42%). Drying (water content of 0.3% or less), then cooling, crushing, sieving, to produce light calcium carbonate finished products.
