Some explanations of lightweight Calcium Carbonate
Calcium Carbonate is an inorganic compound, common name: limestone, calcite, marble, chalk, aragonite, white marble, etc. Relative molecular weight is 100.09, density: 2.93/m3, melting point: 825°C, it is the main component of limestone and calcite, and its properties are white crystal or powder. It often exists in nature in three crystal forms: calcite, aragonite and vaterite. . Since the development of Calcium Carbonate industry, the ore reserves are abundant, widely distributed, and affordable; powder products are non-irritating, non-toxic and tasteless, with good color and high whiteness, so they are widely used.
Light calcium is Calcium Carbonate prepared by chemical method, which can be roughly divided into two synthesis methods, carbon dioxide gas reaction method and soluble salt reaction method. The chemical composition of light calcium is the same as that of heavy calcium, and its biggest feature is that it can obtain particles of various sizes and shapes according to different carbonation conditions.
As a filler and reinforcing agent, lightweight Calcium Carbonate can not only increase the volume and reduce the cost, but more importantly, it can improve the processing performance of the matrix, and can also play the role of reinforcement, tensile resistance, wear resistance, tear resistance, and gloss improvement. .
