Calcium carbonate
calcium_carbonate   According to the different production method of calcium carbonate, we can divided into heavy calcium carbonate, light calcium carbonate and colloid calcium carbonate and crystal calcium carbonate.
  Heavy calcium carbonate is a white powder is made from superior calcite, the main composition is CaCO3.It is Insoluble in water and ethanol. It is with the characteristic of high lightness, good impurity, Hue softness and stable chemical composition, it is a very popular mineral filler.
  In paint, Heavy calcium carbonate is safer, low Covering power, but the lightness is not more than Light calcium carbonate's. Light calcium carbonate is easy to be bodied, even to a bolck if with the wrong using method. The amount of oil absorption is much higher than Heavy calcium carbonate. The alkalinity of Light calcium carbonate is higher than Heavy calcium carbonate's. The dry covering power of light calcium is much higher than Heavy calcium's, and the color of light calcium is much ligher than heavy calcium's.
  Calcium carbonate has the following usage With the grinding function of Roymond and high pressure grinder:
1. Within 200 meshes, it can be used in feed additive. And the calcium percent can be reach 55.6 degree without Harmful Ingredients.
2. 250-300 meshes, it can be used in plastic,rubber, paint, waterproof material and interior & exterior wall. The lightness can reach 85 degree or more.
3. 350-400 meshes, it can be used in buckle, water pipe, checmicals. The lightness can reach 93 degree or more.
4. 400-600 meshed, it can be used in toothpaste, soap. The lightness can reach 94 degree or more.
5. 800 meshes, it can be used in rubber, plastic, wires, pve. The lightness can reach 94 degree or more.
6. 1250 meshes, it can be used in PVC, PE, Paint, Coating level product, Paper-making, The lightness can reach 95 degree or more.
