calcium carbonate Application:

Rubber industry

Calcium carbonate is one of the earliest and largest bulk fillers used in the rubber industry. Calcium carbonate is filled in rubber in large quantities, which can increase the volume of the product, thereby saving expensive natural rubber and reducing costs. Calcium carbonate can be obtained by filling rubber. It has higher tensile strength, tear strength, and stronger reinforcing effect in natural rubber and synthetic rubber than pure rubber sulfide, and can adjust the consistency.

Plastic industry

Calcium carbonate can play a skeleton role in plastic products, has a great effect on the dimensional stability of plastic products, can improve the hardness of the products, and can also improve the surface gloss and surface flatness of the products. The addition of calcium carbonate to general plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is above 90%, it can also replace the expensive white pigment to achieve a certain whitening effect.

Paint industry

Calcium carbonate is a large amount in the paint industry, and it is an indispensable skeleton. The amount of the calcium carbonate is more than 30% in the thick paint, and the phenolic enamel paint is more than 39% of the phenolic fine pattern wrinkle paint.

Waterborne coating industry

In the waterborne coating industry, the application is more widely used, and the coating can be made without sedimentation, easy to disperse, and has good gloss. The amount of the waterborne coating is 20-60%.

Heavy (Ground) Calcium Carbonate is widely used as filler and improver.
Purity: 98%min.
Appearance: white powder.

Heavy calcium carbonate, also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 2000 mesh or above, depending on your requirement.

Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.

Calcium carbonate Application:

1)Rubber:

it can reduce the amount of expensive natural rubber,increase its volume ,reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate

2)Chemical manufacturing materials 

it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and easy to process. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc.

3)Painting& coating: 

it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are used in water-based pain

4)Plastic: 

it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products.

5)Paperpulp material: 

it can fully make use of its high whiteness, affinity to water and shock intensity, low cost widely using .

6) Coal-fired power and planted sulfurization

7)Feed,pharmaceutical industry

 making calcium additives, replace the original shell powder to reduce costs.
