Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous.
Active light calcium carbonate
The surface-modified activated calcium carbonate has a reinforcing effect in rubber, and its reinforcing property is comparable to that of white carbon black. It is often used as a reinforcing agent for white, light and colored rubber products. It is easy to disperse in the rubber, but the heat generation is large, and the vulcanization rate will be accelerated after activation. It is used in the manufacture of tire cushioning rubber, inner tube, bicycle inner and outer tires, transmission belt covering rubber, rubber hose, rubber cloth products and rubber shoes. It is suitable for natural rubber, SBS and latex. It has obvious reinforcing effect in SBS and good coloring performance.
Calcium carbonate is one of the earliest and largest fillers used in the rubber industry. Calcium carbonate is filled in rubber in large quantities, which can increase the volume of the product, thereby saving expensive natural rubber and reducing costs. Calcium carbonate can be obtained by filling rubber. Pure rubber sulphide has higher tensile strength, tear strength, and a significant reinforcing effect in natural rubber and synthetic rubber, while adjusting the consistency.
Calcium carbonate can play a skeleton role in plastic products, has a great effect on the dimensional stability of plastic products, can improve the hardness of the products, and can also improve the surface gloss and surface flatness of the products. The addition of calcium carbonate to general plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is above 90%, it can also replace the expensive white pigment to play a certain whitening effect.
Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers.Ceramic tile adhesives typically contain 70% to 80% limestone. Decorating crack fillers contain similar levels of marble or dolomite. It is also mixed with putty in setting stained glass windows, and as a resist to prevent glass from sticking to kiln shelves when firing glazes and paints at high temperature.
