API-Calcium carbonate has passed the national GMP certification. As a medicinal active ingredient, it can be widely used in calcium supplement tablets or made into high-density calcium tablets; It can also be used as a filler for tablet preparations, so as to increase the nutritional components in nutritional supplements tablets; After calcium carbonate granulation, it is more convenient for the stamping of calcium supplement preparation.
The content of calcium carbonate in Xinji, Hubei Province is high, the content of impurities is low, and the contents of Pb, as and Hg are very low. Some indicators meet and exceed the requirements of Chinese Pharmacopoeia (CP2010), American Pharmacopoeia (USP), European Pharmacopoeia (EP) and British Pharmacopoeia (BP). Some indicators can also be adjusted according to customer requirements, especially particle size distribution and tightness density.
It can be used as a filler in rubber, plastic, papermaking, putty, primer, coating and ink industries. It is widely used in the production of organic synthesis, metallurgy, glass and asbestos. It can also be used as a neutralizer for industrial waste water, an antacid for gastric and duodenal ulcers, an antidote for acidosis, a detoxifier for sulfur dioxide in exhaust gas containing sulfur dioxide, a feed additive for dairy cows, and an anti-sticking agent for linoleum.
