White carbon black / nano calcium carbonate composite slurry coating wet ultrafine calcium carbonate is a new technology of functional ultrafine calcium carbonate powder processing, which breaks through the technical bottleneck of surface modification of wet ultrafine calcium carbonate by composite nano slurry, solves the common problem of material defects brought by sharp edges and smooth cleavage surface in wet grinding process of calcium carbonate, and realizes wet carbon The specific surface area of calcium acid increased, the oil absorption value decreased, and the dispersion was better. This technology is the first one in China and won the second prize of "Jiangxi excellent new product" and other awards. After industrial promotion, the market prospect is very broad.
