Calcium carbonate is divided into light calcium carbonate, heavy calcium carbonate and colloidal calcium carbonate.

1. Light calcium carbonate: amorphous powder, tasteless and odorless. It is slightly hygroscopic, stable in dry air, and decomposes in case of acid. The particle size of light calcium carbonate is about 5 μ m。

Heavy calcium carbonate: white powder, odorless and tasteless. Stable in air, almost insoluble in water, slightly soluble in water containing ammonium salt or ferric oxide. Dissolve by effervescence in the presence of dilute acetic acid, dilute, etc., heat to release carbon dioxide and generate calcium oxide. Its activity is greater than that of ordinary calcium carbonate, and it has reinforcement.

2. Calcium carbonate whisker belongs to aragonite structure, white powder. Acicular or fibrous single crystals. It is a fibrous material with good dispersion and uniform size. The length diameter ratio of whiskers is 20~30, and the melting point is 759 ℃. High strength, good heat insulation and good compatibility with resin.

3. Calcium carbonate has three isomers: calcite, aragonite and vaterite. Natural limestone is almost entirely calcite. The colorless crystalline powder prepared by chemical method is almost insoluble in water.

Purpose:

1. Light calcium carbonate can be used as a leavening agent in pastry, bread, biscuits and other foods, and the dosage in general food is 1%. It is widely used, and can also be used as flour treatment agent, anti caking agent, acidity regulator, nutrition enhancer, curing agent, etc.

2. It is used as feed nutrition fortifier.

3. Calcium carbonate whisker is one of the earliest and used amount in rubber industry and plastic industry. In addition, the product is also widely used in paper making, paint, ink industry and daily chemical products.

4. It is a hard abrasive used for toothpaste as a friction agent.

Within 200 meshes: It can be used for various feed additives with calcium content above 55.6, without harmful ingredients.

250 mesh to 300 mesh: used as raw materials for plastic plants, rubber plants, paint plants, waterproof material plants and internal and external wall painting. The whiteness is above 85 degrees.

350 mesh to 400 mesh: used for manufacturing gusset plate, downpipe and chemical industry. The whiteness is above 93 degrees.

400 mesh to 600 mesh: it can be used for toothpaste paste and soap. The whiteness is above 94 degrees

800 mesh: used for rubber, plastic, cable, pvc with whiteness above 94 degrees

1250 mesh: PVC, PE, paint, coating grade product, paper-making primer, paper-making surface coating, whiteness above 95 degrees. It has high purity, high whiteness, non-toxic, odorless, low fine oil quality and low hardness.
