Calcium powder commonly known as limestone, stone powder, the main component is calcium carbonate, is weakly alkaline, insoluble in water, soluble in acid.
Functions: increase product volume, reduce cost, improve processing properties (such as adjusting viscosity, rheological properties, vulcanization properties), improve dimensional stability, reinforcing or semi-reinforcing, improve printing performance, improve physical properties (such as heat resistance, extinction, wear resistance, flame retardant, whiteness, gloss), etc.
Widely used in paper, plastic, plastic film, chemical fiber, rubber, adhesive, sealant, daily chemical, cosmetics, building materials, coatings, paint, ink, putty, sealing wax, putty, felt layer packaging, medicine, food (such as chewing gum, chocolate), feed,etc.
Rubber:
Calcium powder is one of the most widely used fillers in the rubber industry. Calcium powder filled in a large number of rubber, can increase the volume of its products, and save expensive natural rubber, thus greatly reducing the cost. When calcium powder is filled into rubber, higher tensile strength, tear strength and wear resistance can be obtained than that of pure rubber sulfide.
Plastic:
In plastic products can play a skeleton role, has a great effect on the stability of the size of plastic products, but also can improve the hardness of products, and improve the surface luster and surface smoothness of products. Calcium carbonate, which has a whiteness of 90 or more, can also replace expensive white pigments.
Paper:
Calcium powder plays an important role in paper industry, can ensure the strength and whiteness of paper, and the cost is low.
In addition, calcium powder is also used in calcium supplements. It can promote the calcification of bone marrow and teeth, maintain the normal excitability of nerves and muscles, and reduce capillary permeability. It is used to prevent and treat chronic diseases caused by calcium deficiency.
