Jiaozuo nanometer light calcium base

Jiaozuo City, Henan Province is located at the foot of the Taihang Mountains, it is a natural resource of limestone, so the calcium carbonate industry has been booming here. Calcium carbonate react with all the acid occurs to form water and the corresponding calcium salt (such as calcium chloride CaCl2), and release carbon dioxide; at room temperature (25 ℃), the concentration of calcium carbonate accumulated in water 8. 7 × 1029, solubility of 0.0014, pH of the aqueous solution of calcium carbonate is 9.5 ~ 10.2, pH value of air-saturated aqueous solution of calcium carbonate of 8.0 to 8.6. Calcium carbonate toxic, odorless, non-irritating, usually white, the relative density of 2.7 to 2.9. Depending on the shape of calcium carbonate, precipitated calcium carbonate grain shape, and can be divided into spindle-shaped light calcium carbonate, cubic, needle-shaped, chain-shaped, spherical, rectangular and cylindrical sheet-shaped calcium carbonate, these different crystalline forms Calcium carbonate can be obtained by controlling the reaction conditions. PCC its original average particle diameter (d) is divided into: calcium carbonate particles (5μm), micronized calcium carbonate (1 ~ 5μm), fine calcium carbonate (0.1 ~ 1μm), ultra-fine calcium carbonate (0.02 ~ 0.1μm ), ultra-fine calcium carbonate (0.02μm). Limestone and other raw materials segment is burned to generate lime (calcium oxide as the main component) and carbon dioxide, along with water generated digest lime lime (mainly composed of calcium hydroxide), and then pass into carbon dioxide carbonation lime to produce calcium carbonate precipitation, the final dewatering, drying and grinding the system, or first with sodium carbonate and calcium chloride to form calcium carbonate precipitation metathesis reaction, then dehydrated, dried and pulverized and prepared. The chemical formula of calcium carbonate CaCO3. Light calcium carbonate sedimentation volume: 2.5ml / g or more, and a specific surface area of ??about 5m2 / g. PCC fine particles, the surface is rough, large surface area, so the higher the oil absorption value of about 60 ~ 90ml / 100g. Jiaozuo main production base of light calcium carbonate, ultra-fine calcium, nano calcium, calcium activity, calcium powder. Tel Guo Rui 15139125271 0391-7789262
