The difference between heavy and light calcium
Both calcium carbonate light and calcium carbonate heavy are commonly used as fillers in the coating and plastics industry. The content of the first grade is 99.1% and that of the second grade is 97.9%. The difference between heavy and light 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!
