White Powder


Precipitated calcium carbonate is amorphous powder, tasteless, odorless, slightly hygroscopic, stable in dry air, acid decomposition.

Ground calcium carbonate is white powder, odorless and tasteless, stabilize in the air, almost insoluble water.

It can be used as a loosening agent, starter and nutritional calcium supplement in food processing.


Function Application


The difference between ground and precipitate calcium carbonate is as follows:

1. The main difference is that light calcium is used for fillers, welding electrodes, organic synthesis, etc. Heavy calcium is used for the production of anhydrous calcium chloride, cement, etc.

2. Ground calcium carbonate or heavy calcium carbonate is calcium carbonate, which is cheap because it is prepared by compressing calcite, and tends to settle when used in emulsioni paint compared with light calcium carbonate.Lightweight calcium carbonate, also known as precipitated calcium carbonate, was found to be progressively smaller in size, larger in oil absorption and higher in price.They are commonly used in latex paint fillers, with the use.

3.Heavy calcium is made by crushing ore, while light calcium is made by artificial synthesis.There is a large amount of coating.

4. Heavy calcium is stable, but relatively light calcium sinks easily.

Light calcium is better in the settlement, but the oil absorption is greater than heavy calcium, the price is generally more expensive than heavy calcium, although the stability is not as good as heavy calcium, but still have stability, even if the external wall
paint, its dosage is also very large!
