method of manufacturing a material for calcium carbonate, finely concassee overall type guard and pcc, products thus obtained and their uses

摘要

The invention relates to a method for preparing a calcium carbonate material comprising GCC ("crushed calcium carbonate") and PCC ("pre calcium carbonate").Particle fraction less than 1 $g ($m)(in thousands of dollars)(in thousands of dollars)Or 95%Synthesis of SCCPs and SCCPs into a special area of 25 m2 / g in a cost-effective manner, possibly with at least another membrane material. The invention also relates to a calcium carbonate material as a combination of a water suspension and a drying product. The invention also relates to the use of these products in any department using film materials, especially in the papermaking, paint and plastic industries.
