Classification of production methods According to the different production methods of calcium carbonate, calcium carbonate can be divided into heavy materials Calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. | ||
Difference between heavy calcium and light calcium: |
Both light and heavy calcium carbonate are commonly used as fillers in coatings and plastics industries. The content of primary grade was 99.1%, and that of secondary grade was 97.9%. The difference between heavy calcium carbonate and light calcium carbonate is as follows: |
1.the main difference is that light calcium is used for filler, welding rod, organic synthesis, etc., heavy calcium is used for the production of anhydrous calcium chloride, cement, etc. 2.Heavy calcium carbonate or heavy calcium carbonate is calcium carbonate because it is prepared by compressing calcite and tends to settle when used in latex paints compared to light calcium carbonate. Light calcium carbonate, also known as precipitated calcium carbonate, is found to be getting smaller, more oil absorbent and more expensive. They are often used as latex paint fillers, with use. 3.heavy calcium is made of crushed ore, light calcium is synthetic, there are a lot of coating. 4.heavy calcium is stable, but relatively light calcium is easy to sink. Light calcium sedimentation is good, but the amount of oil absorption is greater than heavy calcium, the price of calcium is generally expensive, although the stability is not as good as heavy calcium, but there is stability, even if the exterior wall paint, its dosage is also very large! |
