Wide application of calcium carbonate in major fields
Wide application of calcium carbonate in major fields
1. Plastic industry
As a key filler in the plastic industry, calcium carbonate has the following functions:
Reduce costs: With its low price, it effectively reduces the production cost of plastic products.
Improve performance: Improve the dimensional stability, heat resistance and rigidity of plastic products.
Widely used: Applicable to the production of plastic products such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP).
2. Papermaking industry
In the papermaking industry, calcium carbonate plays an indispensable role:
Improve paper quality: Improve the whiteness, opacity, smoothness and printability of paper.
Reduce costs: As a filler, it can effectively reduce the amount of pulp used, thereby reducing production costs.
Environmental advantages: Non-toxic and harmless, in line with environmental standards, to help the green development of the papermaking industry.
3. Paint industry
The role of calcium carbonate in the paint industry is mainly reflected in the following aspects:
Filling and skeleton function: Reduce the amount of resin and reduce costs.
Improve construction performance: Improve the leveling, hiding power and storage stability of the paint.
Environmentally friendly coatings: As an environmentally friendly material, it is highly consistent with the green development trend of the industry.
4. Rubber industry
In rubber products, calcium carbonate is mainly used as a filler and reinforcing agent:
Reduce costs: Increase the volume of rubber products and significantly reduce production costs.
Improve performance: Improve the wear resistance, tear strength and tensile strength of rubber products.
Widely used: Suitable for the production of various rubber products such as tires, hoses, tapes, seals, etc.
5. Other fields
Calcium carbonate also shows wide application value in other industries:
Building materials industry: As an important raw material for cement and concrete, it improves the strength and durability of building materials.
Food industry: Food-grade calcium carbonate can be used as a calcium supplement and is widely used in food and health products.
Pharmaceutical industry: As a pharmaceutical excipient, it is used in the preparation of tablets and capsules.
Environmental protection field: It plays an important role in environmental protection projects such as flue gas desulfurization and sewage treatment.
