Desulfurized heavy calcium powder

Heavy calcium carbonate belongs to trigonal crystals, often appearing as complex trigonal and rhombohedral crystals. The aggregates are plate-like or fibrous, dense blocky, granular (marble), earthy (chalk), porous, bell like, oolitic, bean like, nodular, grape like, and crystal group like. Colorless or white, sometimes colored by elements such as iron, manganese, copper, etc. Stained in light yellow, light red, purple, and brown.
Heavy calcium carbonate can be used as a filler for polymer based composite materials such as plastics, rubber, adhesives, etc. Its application characteristics or advantages are that the volume of heavy calcium carbonate filling materials is small and the density is high under the same filling amount; Due to its small specific surface area and oil absorption value, it is easier to mix with resin; However, the types and contents of impurities in different raw materials vary, resulting in unstable color of the PRODUCTS. Heavy calcium carbonate is divided into heavy calcium carbonate for paper industry, heavy calcium carbonate for plastic industry, heavy calcium carbonate for coating industry, and heavy calcium carbonate for rubber industry.
