Description

Introduction: 

Light calcium carbonate is also called precipitated calcium carbonate and its chemical formula is CaCO3. Light calcium carbonate is non-toxic, odorless, non-irritating and usually white. Because its settling volume (2.**2.8mL/g) is larger than that of heavy calcium carbonate produced by mechanical.
method (1.**1.9mL/g), it is called light calcium carbonate. It can be used in rubber industry, plastic industry, paint industry, water-based paint industry, paper industry, cable industry and other industries.

 

Also called precipitated calcium carbonate, or light calcium for short, is prepared by calcining limestone and other raw materials to generate lime (the main component is calcium oxide) and carbon dioxide, adding water to digest the lime to generate lime milk (the main component is calcium hydroxide), then introducing carbon dioxide to carbonize the lime milk to generate calcium carbonate precipitate, and finally dehydrating, drying and pulverizing. Or the calcium carbonate precipitate is generated by double decomposition reaction of sodium carbonate and calcium chloride, and then is dehydrated, dried and crushed. Light calcium carbonate is called light calcium carbonate because its settling volume (2.**2.8mL/g) is larger than that of heavy calcium carbonate (1.**1.9mL/g).
