The role of diatomaceous earth and calcium carbonate

Calcium Carbonate Role: Calcium carbonate can be used as a filler in rubber, plastics , paper, coatings and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a neutralizer of industrial wastewater, an acidifier for gastric and duodenal ulcer disease, an antidote for acidosis, an SO eliminator in SO-containing exhaust gases, a feed filler for dairy cattle, and an anti-adhesive agent for linoleum. It can also be used as raw material for tooth powder, toothpaste and other cosmetics.

Diatomaceous earth role: Diatomaceous earth has a wide range of roles, and can effectively adsorb formaldehyde, but also benzene and ammonia and other harmful gases have a strong adsorption. It can absorb or release water automatically according to the humidity in the air, and has the effect of regulating air humidity. Diatomaceous earth will automatically release negative oxygen ions, which can remove odors in the air and have the effect of purifying the air. In the soil can play a moisturizing, loosening soil, prolonging the efficacy of medicine and fertilizer time, to help crops grow.

Characteristics of Diatomaceous Earth and Calcium Carbonate:

Diatomaceous earth paint additive products, with large porosity, strong absorption, chemical stability, wear-resistant, heat-resistant and so on, can provide coatings with excellent surface properties, capacitation, thickening, as well as improve adhesion. Due to its large pore volume, it can shorten the drying time of the coating film. It also reduces the amount of resin used and lowers costs. This product is considered to be an efficient matting powder product for coatings with good cost performance, and has been widely used in water-based diatomaceous earth as a designated supply by many large international coating manufacturers.

Calcium carbonate is columnar or rhombic in shape, with a density of 2.93g/cm3, a melting point of 1339℃ (decomposed at 825-896.6℃), and a melting point of 1289℃ at 10.7MPa. It is insoluble in alcohol, soluble in chlorinated diatomaceous earth, and soluble in chlorinated diatomaceous earth. Hard to dissolve in alcohol, soluble in ammonium chloride solution, almost insoluble in water.
