Haimeng study Industrial Co., Ltd. 99% of the domestic food-grade calcium carbonate

The amount of detail Haimeng study Industrial Co., the manufacturer of high-quality, calcium carbonate phone manufacturers, calcium carbonate, CAS number, the latest offer Shanghai calcium carbonate, calcium carbonate, calcium carbonate prices, calcium carbonate manufacturers latest offer, calcium carbonate , calcium formula, the molecular weight of calcium carbonate. English: Calcium carbonate Common names limestone, calcite, marble, chalk, aragonite, white marble. Formula CaCO3. The molecular weight of 100.09. A melting point of 825 ° C. The main components of CaO accounted for 56.03%, Co2 accounting for 43.97. Density 2.93g / cm3. Mohs hardness 3. Decomposition temperature of 898 ° C melting point when the pressure is 10.4MPaJF, a melting point of 1339 ° C state: white powder. Odorless and tasteless. Stability in the air, easy to absorb odors. Dissolved in acetic acid, hydrochloric acid and so on. Insoluble in sulfuric acid, almost insoluble in water and ethanol. In water containing salt or ferric oxide is dissolved. Properties: In case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid happen bubble boiling, and dissolved. Decomposed into calcium oxide and carbon dioxide when heated at 101.325 kPa to 900 ℃. Purpose: Within 1,200 Head: can be used for a variety of feed additive calcium amounted to 55.6 over 2,250 non-harmful ingredients mesh to 300 mesh: used plastic factory, rubber factory, paint factory, waterproof material plant materials and interior and exterior paint. Whiteness above 85 degrees. 3,350 mesh to 400 mesh: for the manufacture pinch, the water pipes, chemical. Whiteness above 93 degrees. 4,400 mesh to 600 mesh: paste can be used for toothpaste, soap. Whiteness above 94 degrees 5,800 Head: used in rubber, plastics, cables, pvc whiteness above 94 degrees 6,1250 head: pvc, PE, paint, paint-grade products, paper primer, paper coating, white degree above 95 degrees. With high purity and high brightness, non-toxic, odorless, fine oil, low hardness 7. The calcium carbonate can be used as calcium supplements: calcium is one of the highest absorption rate of up to 39% soluble in stomach acid, it has become the largest forms, the most widely used of calcium supplements. 8. alkaline calcium carbonate, commonly used in the improvement of acid soils Haimeng study Industrial Co., integrity management, welcomed the new and old customers call to discuss!
