Heavy calcium carbonate

Heavy calcium carbonate (calcium carbonate), referred to as calcium carbonate, is made from natural carbonate minerals such as calcite, marble and limestone. It is a common powdery inorganic filler with high chemical purity, high inertia, no chemical reaction, good thermal stability, no decomposition below 400 C, high whiteness, low oil absorption rate, low refraction rate, soft and dry, no crystalline water, low hardness, low wear value, innoxious, odorless, good dispersity and so on. The ordinary heavy calcium powder, ultra-fine calcium carbonate, wet grinding superfine calcium carbonate and ultrafine surface modified heavy calcium carbonate can be provided according to the requirements.
The application of heavy calcium carbonate:
"Heavy calcium" is calcite powder, the abbreviation of "heavy calcium carbonate". The main ingredient is heavy calcium carbonate, and heavy calcium carbonate is also referred to as "heavy calcium". It is usually used as a filler. It is usually used as a filler. It is widely used in artificial floor tiles, rubber, plastics, paper, paint, paint, ink, cable, construction supplies, food, medicine, textile, and textile. Feed, toothpaste and other daily chemical industry, as filler to increase the volume of products, reduce production costs. In the series of heavy calcium carbonate products, it is the best made by natural calcite as raw material. Its calcium content is very high (more than 99%), and the content of harmful metal compounds is very small, so it is also used in food, medicine, cosmetics, toothpaste, feed and other industries. Filling the heavy calcium carbonate products in plastic products can play a framework role in the stability of the plastic products, can improve the hardness and heat resistance of the products, and improve the surface gloss and surface smoothness of the products. Because calcium carbonate has more than 90% whiteness, it can also replace expensive white pigment to play a certain whitening effect.
The use of heavy calcium carbonate:
1. Adding 30% specially treated calcium carbonate to the plastic products can make the notch impact strength of the product reach 10%~120%, and the thermoplastic, elastic body and toughness can reach the same level of the modified products.
2. Adding calcium carbonate and talcum powder into the PE film can make the film have a good barrier to infrared radiation and improve the service life of the film.
3. The automobile parts made of superfine calcium carbonate filled with modified plastic products can meet the standard requirements of Volkswagen VW44045.
4, filled plastic, rubber blend material has high toughness, high rigidity, easy processing and other characteristics. When making motorcycle components, it is similar to ABS in processing and performance.
