Background technique

Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, and calcite. It is a compound. Calcium carbonate is an important building material and has a wide range of industrial uses. Light calcium carbonate can be used as a leavening agent, flour Treatment agent, anticaking agent, acidity regulator, nutrient enhancer, curing agent, etc. Calcium carbonate can also be used as feed nutrient enhancer, rubber filler, analytical reagent, white color of plastic, paper, rubber, paint, ink, etc. Filling agent, raw materials for making face powder, pressed powder, gouache, rouge, etc., has a wide range of uses, and calcium carbonate raw materials need preliminary processing before use.
