Third, the physical properties: heavy calcium carbonate called TSP is a natural calcium carbonate minerals such as calcite, marble grinding together. Non-toxic, non-irritating, tasteless, good color, high brightness, low interference to other colors, easy to color, low calcium hardness how much money one ton light damage on the processing equipment, chemical stability, is inert fillers, heat decomposition temperature of 800 o C or more, easy to dry, easy to remove moisture, no crystal water, and low prices. ② applications in plastics plastics industry is the largest consumer of heavy calcium carbonate fields, heavy calcium refinement, can significantly improve the mechanical properties and strong bonding strength plastic composite interface. Plastics used in fine heavy calcium, can reduce the manufacturing cost of calcium carbonate, but also improve and change its properties. Calcium carbonate is an inorganic compound calcium carbonate, commonly known as: travertine, limestone, stone, marble and so on. Main components: calcite, is a compound of the formula is CaCO fine calcium carbonate, neutral, substantially insoluble in water, soluble in hydrochloric acid?.
