1. Used in plastic production
Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylic butadiene-styrene copolymer (ABS) and other resins. Adding calcium carbonate has a certain effect on improving certain properties of plastic products to expand their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) The product can have certain special properties;
(7) Reduce the cost of plastic products
1. Light calcium carbonate can be used as leavening agent, flour treatment agent, anticaking agent, acidity regulator, nutrition enhancer, curing agent, etc.
2. Used as a feed nutrition enhancer.
3. Calcium carbonate whisker is one of the earliest used and most used fillers in rubber industry and plastic industry. In the rubber industry, it is widely used in hoses, rubber sheets, rubber cloth, rubber shoes and medical products, and is a good filler for reducing product costs.
4. Calcium carbonate whisker is one of the earliest used and most used fillers in rubber industry and plastic industry. In the rubber industry, it is widely used in hoses, rubber sheets, rubber cloth, rubber shoes and medical products, and is a good filler for reducing product costs. In the plastics industry, it is mainly used for soft polyvinyl chloride composites, plastisols and glass fiber reinforced polyester composites, such as wire sheaths, artificial leather and other extruded and rolled products. The general dosage is about 20 parts. There are also a large number of applications in calcium plastic materials, such as rigid PVC pipes and plates. In addition, this product is also widely used in papermaking, coating, ink industry and daily chemical products.
5. Compared with general granular calcium carbonate, calcium carbonate whiskers show significant strengthening and toughening effects. Calcium carbonate whiskers can be used to reinforce plastics and rubber. For example, it can be used as a reinforcing modifier for polyamide, polycarbonate, thermoplastic polyester, ABS, PP and other resins, while reducing costs, it can also improve the bending strength, dimensional stability, and thermal stability of the product. Used as high-grade paper filler in the paper industry, this paper can be used as a flame-retardant paper for interior decoration and other aspects. Calcium carbonate whisker is non-toxic and is an ideal substitute for asbestos. It can be used as a friction material instead of asbestos to manufacture friction materials such as automobile brake pads.
6. It is a rubber filler, which can make the rubber bright in color, high elongation, high tensile strength and good wear resistance. It is also used as a filler in industries such as artificial leather, wires, polyvinyl chloride, coatings, inks and papermaking. When used in the production of microporous rubber, it can be foamed uniformly.
7. Used as an analytical reagent, such as a reference reagent. Sample flux and volatile additives in emission spectrum analysis. It is also used as silicon single crystal slicing glue, thick film capacitor material, optical glass and raw material for pharmaceutical industry.
