What Is Dolomite Powder Commonly Used For


The chemical composition of dolomite is CaMg(CO3)2, the Mohs hardness is 3.5-4, and the specific gravity is 2.8-2.9.

Different fineness dolomite powder can be applied for various fields, specific fineness and usages are as follows:

1. Coarser than 200mesh: It can be used for a variety of feed additives (calcium content should be more than 55.6%, with no harmful ingredients);

2. 250-325mesh: Used for plastic, rubber factory, paint factory, waterproof material plant as raw materials and interior and exterior paint coatings (whiteness should be more than 85 degrees);

3. 350-400mesh: Used for the manufacture of pinch, the water pipes, chemical (whiteness should be above 93 degrees);

4. 400-600mesh: Can be used for toothpaste, soap (whiteness should be more than 94 degrees);

5. 800mesh: Used in rubber, plastics, cables, PVC (whiteness should be more than 94 degrees);

6. 1250mesh: Used for PVC, PE, paint, paper primer, topcoat paper (whiteness should be more than 95 degrees);

In addition, the dolomite powder has characteristics of high purity and high brightness, non-toxic, odorless, fine oil, low hardness, can be used as calcium supplements, the absorption rate can be up to 39%, right after the Calcium citrate malate, it is soluble in gastric acid, it has the most formulations and become the most widely-used calcium supplements; Also, because the dolomite is one kind of calcium carbonate, it is alkaline, often used to improve acidic soil.
