Wide range of applications of heavy calcium carbonate: from filler to environmental protection industry
Heavy calcium carbonate(heavy calcium carbonate for short) is a colorless, odorless white powder that is almost insoluble in water and alcohol solvents. When it encounters dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it will bubble and dissolve; when heated to 898°C, it begins to decompose into calcium oxide and carbon dioxide. Heavy calcium carbonate is mainly produced by grinding natural carbonate minerals such as calcite, marble and limestone. As a commonly used powdery inorganic filler, it has many significant advantages, such as high chemical purity, strong inertness, and resistance to chemical reactions. , good thermal stability (does not decompose below 400°C), high whiteness, low oil absorption, low refractive index, soft, dry, no crystal water, low hardness, low wear, non-toxic, tasteless, odorless and dispersible Good to wait.
Heavy calcium carbonate is widely used in many industries. As a filler, it can increase product volume and reduce production costs. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, building materials, food, medicine, textiles, feed, toothpaste, etc. As a filler, heavy calcium can not only improve the physical properties of the product, but also significantly reduce production costs. For example, in rubber products, heavy calcium can increase the volume of rubber, improve its processability, play a semi-reinforcing or reinforcing role, and adjust the hardness of rubber.
