Application Examples of Anhydrous Calcium Carbonate_Industrial Additives

Background and overview of application examples of anhydrous calcium carbonate

Anhydrous calcium carbonate is a white crystalline powder, soluble in dilute acid and almost insoluble in water. Calcium carbonate is a commonly used inorganic filler. It is widely used in plastics, rubber, coatings and other fields because of its wide source and low price.

Application Examples of Anhydrous Calcium Carbonate Application 1.

CN201910927731.3 discloses a solid multiple self-emulsifying carrier and a preparation method thereof, which includes the following raw materials in proportions by weight: 4-6 grams of ascorbic acid, 2-4 grams of astaxanthin, 40-50 grams of water, Polyglyceryl ricinoleate 10-14 grams, hydrogenated castor oil 14-18 grams, coconut oil 30-32 grams, anhydrous calcium carbonate 90-100 grams. Most of the heavy metals and other harmful substances in the water can be removed through deionized water, making it harmless to humans when used. The addition of liquid lipid coconut oil has strong activity, allowing the emulsion to be effectively increased after adding a variety of substances. The activity allows the active ingredients to be absorbed quickly. By adding the modified polymer emulsifier polyglyceryl ricinoleate and the non-ionic emulsifier hydrogenated castor oil and stirring evenly, the solid can be quickly emulsified effectively, and anhydrous calcium carbonate is added to enable the aluminum magnesium carbonate material to be shaped and become It should be thick enough so that it does not adhere to the surface of the skin when applied.

CN201610595886.8 provides a brown vat dye and a preparation method thereof. The raw material components include the following: 7-11 parts of 1,5-dichloroanthraquinone, 6-8 parts of 1-aminoanthraquinone, and 2 copper powder -3 parts, anhydrous calcium carbonate 6-9 parts, urea 11-14 parts, sodium fluoride 7-12 parts, anhydrous sodium acetate 5-9 parts, aluminum trichloride 3-7 parts. The method adopts a shrinkage reaction first, and then performs a closed-loop reaction. During the reaction, the utilization efficiency of raw materials is greatly improved, the waste of raw materials and emission pollution are avoided, and the various processes are connected with each other, effectively shortening the production cycle. Makes the raw materials mixed more evenly. The raw materials of each component are easy to obtain, greatly reducing the preparation ingredients, and can be further promoted and applied in actual industrial production.
