Calcium carbonate powder Usage and Synthesis.

1）Tyre: light calcium carbonate and nano calcium carbonate are often used to partially replace low-structure carbon black and silica in the outer rubber (more than 70%) and inner rubber of power car tyres, and in the car tyre carcass cord fabric rubber, airtight ply rubber, inner liner rubber and inner tube rubber to reduce the production cost.

In addition, nano-calcium carbonate and ultra-fine active zinc oxide and replace ordinary zinc oxide can improve the tensile strength, elongation, flexural properties and fatigue resistance of car tyre tread rubber.

(2) Hose and tape: light calcium carbonate and nano-calcium carbonate for hose and tape, one is to play the role of white reinforcing filler, and the second is to improve the dispersion of the rubber. Calcium carbonate in the hose can be used for ordinary hoses, coloured hoses, hydraulic hoses and short-fibre reinforced hoses, etc., in the tape can be used for conveyor belts, transmission belts and timing belts.

(3) rubber shoes: calcium carbonate can adapt to different colour requirements, can improve the rubber mixing and extrusion performance, in the rubber shoes are widely used, often with carbon black, silica, titanium dioxide and clay and used in rubber shoes, uppers, soles and heels and other parts.

(4) wire and cable: calcium carbonate is generally used with carbon black, silica, clay and talc, etc. and used as mining wire and cable, marine wire and cable, high-voltage wire and cable sheathing and electrical wire and cable rubber reinforcement filler.

In the chlorinated rubber, such as CR, chlorinated polyethylene rubber (CM) and chlorinated cis-butadiene rubber as the main material of the wire and cable rubber, calcium carbonate in addition to the role of reinforcing filler, but also to reduce the acidity of the rubber and absorb hydrogen chloride produced during the processing of rubber, thus avoiding the rubber to appear delayed vulcanisation and the role of the phenomenon of the return to the original, and at the same time, to improve the performance of the rubber extrusion.

Uses and functions of Calcium carbonate.

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 neutralising agent for industrial wastewater, acid making agent for gastric and duodenal ulcer disease, antidote for acidosis, sulphur dioxide eliminating agent for sulphur 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 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, rubber moulding products, and other cosmetic products. It can be used as filler of wire insulation layer, rubber moulding products and asphalt linoleum.

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

Uses of Calcium carbonate.

Product method of Bulk Calcium carbonate.

Crushing method will be white stone (natural limestone) first in the jaw crusher coarse crushing, so that the block size of 40 - 60mm, and then lifting machine to Raymond crusher for crushing. The blower will blow the crushed semi-finished products to the cyclone classifier for grading. Coarse products return to the crusher for reprocessing. Qualified products are separated by cyclone separator to get products.
