Precipitated calcium carbonate and calcium carbonate to distinguish the difference with the method?

Chemically precipitated calcium carbonate and calcium carbonate to be the product of the main process is: calcined limestone, lime digestion, clean milk of lime, lime carbonation, dehydration, dry screening. The density of the calcium carbonate proportion of calcium carbonate to light. White is usually high, the whiteness of national standards is more than 90. Settlement volume higher than 2.5 in general. Fine particle size can do more, such as ultra-fine calcium, the calcium micro-, nano calcium.

Calcium carbonate is used to be the physical approach and calcium carbonate products, typically used for high-purity limestone (such as: calcite, chalk, etc.) to carry out grinding, the density of calcium carbonate than the light to heavy, general whiteness Lower. Settlement low volume. Size is more difficult to do fine (but now flow through the sieve can be very small, but not to nanometer).

Hint:If there is any inconsistency or conflict between the English and Chinese versions, the Chinese version shall prevail for all purposes.
