It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
The Thang Long joint operation company, which owns 40% of the shares of PetroVietnam and holds 60% of the shares of Talisman Energy of Canada, said that it was named after Hai Su Den (Black Sea Lion). The results of the oil testing conducted by offshore oil fields showed that the daily crude oil flow of the oil field reached 15,000 barrels.
The “Tuoi Tre†reported that the newly discovered Hai Su Den offshore oil field is located in Block No. 15-2/01, about 60 kilometers from the coast of the Ba Ria Vung Tau Province, a petroleum center in southern Vietnam.
