Calcium carbonate: an all-purpose material_Industrial additives

Calcium carbonate (CaCO₃): an inorganic compound, commonly known as: gray stone, limestone, stone powder, marble, etc. Calcium carbonate is neutral, basically insoluble in water, and soluble in hydrochloric acid. It is one of the common substances on earth.

Calcium carbonate: an all-purpose and versatile material. The role of calcium carbonate in industrial production

Calcium carbonate: an all-purpose material for the rubber industry

Calcium carbonate is one of the earliest and largest fillers used in the rubber industry. Calcium carbonate is filled in large amounts in rubber, which can increase the volume of the product, thus saving expensive natural rubber and reducing costs. Calcium carbonate is filled in Rubber can obtain higher tensile strength, wear resistance, and tear strength than pure rubber vulcanize, and has a significant reinforcing effect in natural rubber and synthetic rubber, and the consistency can be adjusted at the same time. Plastic industry: Calcium carbonate can play a skeleton role in plastic products, which plays a great role in the dimensional stability of plastic products. It can improve the hardness of the products, and can also improve the surface gloss and surface smoothness of the products. Adding calcium carbonate to general plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is above 90%, it can also replace expensive white pigments and play a certain whitening effect.

Calcium carbonate: an all-purpose material for the paint industry

Calcium carbonate is used in a large amount in the paint industry and is an indispensable skeleton. It is used in thick paints at more than 30%, and in phenolic enamel paints 4-7% is more than 39% in phenolic fine pattern wrinkle paints.

Calcium carbonate: an all-purpose material for the water-based coating industry

In the water-based coating industry, it has a wider range of uses. It can make the coating non-settling, easy to disperse, and have good gloss. The dosage in water-based coatings is 20-60%.

In addition, calcium carbonate plays an important role in the paper industry to ensure the strength, whiteness and low cost of paper. It can play a certain insulation role in the cable industry.

Calcium carbonate: an all-purpose and versatile material. The role of calcium carbonate in cosmetics

Adding nano-scale calcium carbonate to cosmetics can make the products delicate and smooth, improving the performance and quality of the products. Use it as an additive to make setting powder, which can eliminate the brightness of foundation powder, protect the adhesion of the skin, and has moderate oil absorption and anti-sweat effects. It can also be used as talcum powder, which does not irritate the skin, has uniform color and a certain covering power. The current development trend of cosmetics at home and abroad is therapeutic, functional and natural. Nanoscale calcium carbonate meets food and pharmaceutical grade standards. It meets the special requirements of cosmetics and is expected to be fully used in more and more high-end cosmetics.

Calcium carbonate: an all-purpose and versatile material. The role of calcium carbonate in food

Biological calcium carbonate is a high-quality calcium source refined from oyster shells and other biological raw materials. It contains high calcium content. Its calcium content is 3 times that of calcium lactate and 4 times that of calcium gluconate. It is easy to absorb and has no peculiar smell. , high biological potency and small side effects; it can be widely used in food, medicine, health care products and other industries. In addition to being a nutritional fortifier, it can also be used as an alkaline agent, dough conditioner or anti-caking agent. Widely used in food, medicine, health food, etc.

Uses of edible calcium carbonate: used as leavening agent in food processing, nutritional fortifier, flour improver, anti-caking agent, fermentation agent, pH value regulator, etc.; Bromopyridine is used as neutralizing agent in the pharmaceutical industry. It is used as filter aid, buffering agent and anti-caking agent as well as filler and calcium source; in daily chemical factory products, due to its high purity and fine particles, it can be used as filler and abrasive in high-end toothpaste, cosmetics production, etc.

Calcium carbonate is used as an alkaline agent in food processing; nutritional supplement; dough conditioner; curing agent; yeast food; anti-caking agent; loosening agent; leavening agent; gum additives and modifiers; white Pigments (food surface colorants)

Bismuth subcarbonate

Adding amount of calcium carbonate: According to national standards, the recommended dosage is one thousandth to three thousandths.
