Active calcium carbonate

Active calcium carbonate is used as a high grade filling agent, which is widely used in rubber, plastic, plastic steel doors and windows, PVC cable materials, advanced coatings, pipes, tires, sole, polyethylene blowing film, sealant strips, fiberglass products, cable wrapper, paper making, building materials, ink, daily chemical industry, textile, feed, food and food. Additives and other industries.
1, in plastics, the stability, hardness and steel content of plastic products can be improved, the processability of plastics and the heat resistance and astigmatism of products can be improved.
2. Filling agent in rubber can increase volume, reduce cost, improve processability and vulcanizing property.
3. In paper making, it can be used as filler for paper, white pigment for coated paper, filler for calcium plastic paper and so on.
4. As a filler in the paint, it can play a skeleton role, so it is called "physical pigment"; in oil coatings, the filling amount can reach 10-50%, and the filling amount in water-based coatings can reach 10-20%.
Activated calcium carbonate is used as base material, and multifunctional surface active agent and compound high efficiency processing aid are applied to modify the surface of inorganic powder. The modified calcium carbonate powder has a special cladding structure on the surface, which can significantly improve the dispersion and affinity in polyolefin and other polymer matrix, and can produce interfacial action with the polymer matrix, thus improving the impact strength of the products. It is a kind of excellent incremental filling additive. The amount of filling is generally 30-100%, and some products even more than 100.
[use]
1, 200 mesh: it can be used for all kinds of feed additives with calcium content above 55.6 and no harmful ingredients.
2, 250 mesh to 300 mesh: used as raw materials for plastic factories, rubber factories, paint factories, waterproofing materials factories, and interior and exterior walls. The whiteness is above 85 degrees.
3, 350 mesh to 400 mesh: used for manufacturing buckles, water pipes, chemical industry. The whiteness is above 93 degrees.
4, 400 mesh to 600 mesh: can be used for toothpaste paste, soap. The whiteness is above 94 degrees.
5, 800 mesh: for rubber, plastic, cable, PVC whiteness is above 94 degrees.
6, 1250 mesh: PVC, PE, paint, coating grade, papermaking base coating, papermaking surface coating, whiteness is above 95 degrees. It has high purity, high whiteness, non-toxic, odorless, low oil quality and low hardness.
[process and process]
Comminution method: the finished product is crushed, graded and separated by using Raymond mill or other high pressure mill, which contains more than 90% CaCO3 of white stone.
Packing: packing in plastic bags with net weight of 50 kilograms per bag. The precautions for storage and transportation are stored in the dry storeroom. To prevent bags from breaking in transportation. It is not allowed to mix with liquid acids.
