With the increasing innovation of ground calcium carbonate (GCC) technology. In many fields, the use of superfine modified GCC instead of precipitated calcium carbonate (PCC) has gradually become a trend.
As we all know, the main advantages of PCC are large specific surface area, large volume, light weight and good filling, but with the continuous improvement of fineness of GCC and the increasingly mature modification process, all kinds of rubber, pipe, calendatory film, nylon plastic and other industries have begun to use more than 2000 mesh superfine GCC instead of PCC. This product is called coated calcium carbonate (CCC)
At present, the settlement volume of CCC can be more than 2.6mL /g, reaching the level of high-quality PCC, and has oil-hydrophobic characteristics. Compared with traditional PCC, CCC has better dispersion and liquidity, and has obvious advantages in whiteness, oil absorption value, price, and stability, and products also have better toughness and gloss
Therefore, in addition to some strict requirements of ultra-light products in the industry, more and more manufacturers began to use ultrafine modified ground calcium carbonate (CCC) instead of light calcium.
