Superfine ground calcium carbonate is a domestic new product, new process, and new technology. Its varieties are YT90 paste, YT90 paste, YT60 paste and so on. At present, it is mainly used in the coated paper and board industry. Its technology is the national patent technology of the China Pulp and Paper Industry Research Institute. Its products are characterized by high whiteness, fine particle size, reasonable particle size distribution, and low viscosity. Its performance lies in: (1) effectively improving the whiteness, gloss and gloss of the coated paper and paperboard; (2) increasing the solid content of the paint; (3) improving the flowability and rheology of the paint; and reducing the generation of scratches during coating; 4 Saving and whitening
