Industrial Activated Precipitated Calcium Carbonate
Industrial Activated Precipitated Calcium Carbonate
The actived calcium carbonate is modified on the basis of common calcium carbonate, so as to achieve the dual purpose of filling and modified in accordance with the material products. These modifications include modification of crystalline morphology, particle size, particle size distribution and surface properties of calcium carbonate. After activation treatment, the molecular structure was changed and the particle size distribution was uniform, showing strong hydrophobicity. To improve its comprehensive performance. It can reduce the cost and improve the hardness, elastic modulus, dimensional stability and thermal stability of the products.

Application：
1.Plastic: In plastic can improve the size of plastic products stability, hardness and steeliness, improve plastic processing properties and products of heat resistance and astigmatism
2.Rubber: As filler in rubber, it can increase volume, reduce cost, improve processing performance and vulcanization performance;
3.Papermaking: In papermaking can be used as paper filler, coated paper white pigment, calcium plastic paper filler etc.;
4.Coating products: As a filler in the coating, can play a skeleton role, so called “physique pigment”; In the oil coating, the filling amount can be up to 10-50%, in the water-based coating filling amount can be up to 10-20%.
