Heavy calcium powder is the trade name of limestone as a mineral raw
material. Limestone is widely used in the history of human civilization because
of its wide distribution and easy access in nature. As an important building
material, it has a long history of mining. In modern industry, limestone is the
main raw material for the manufacture of cement, lime and calcium carbide. It is
an indispensable flux limestone in the metallurgical industry. The high-quality
limestone is widely used after ultra-fine grinding. Used in the manufacture of
paper, rubber, paint, paint, medicine, cosmetics, feed, sealing, bonding,
polishing and other products. According to incomplete statistics, the ratio of
limestone and building stone consumed by cement production, lime production,
metallurgical flux, and superfine calcium carbonate consumption limestone is
1:3. Limestone is a non-renewable resource. With the continuous advancement of
science and technology and the development of nanotechnology, the application of
limestone will be further broadened.
Heavy calcium powder is an important building material. The white and pure
calcium carbonate rock is called white marble, which can be used directly as a
decorative stone pillar or handicraft; the calcium carbonate which has a
beautiful pattern due to impurities is called marble, which is used to make the
veneer or the ground of the outer wall and inner wall of the building; The
densely packed calcium carbonate rock (limestone) can also be used directly for
building houses, but the main use of limestone is to produce cement.
