Abstract

The invention discloses a high-dispersion nano-calcium carbonate preparation equipment and a preparation method. The equipment includes a reaction kettle, drying equipment, a mud pump and a controller. The preparation method is digested, aged, filtered, carbonized, activated, washed and dried. , improve the dispersion of nano-calcium carbonate, and the preparation equipment is used in conjunction with the preparation method. The preparation equipment and method for highly dispersed nano-calcium carbonate described in the present invention has the advantages of reasonable structure, simple structure, convenient use, etc., and effectively solves the problem of low dispersion of nano-calcium carbonate.

Description

technical field [0001] The invention relates to the technical field of preparing nano-calcium carbonate, in particular to a preparation device and method for highly dispersed nano-calcium carbonate. Background technique [0002] Nano-calcium carbonate is a new type of high-grade functional filling material, which is widely used in industries such as rubber, plastics, papermaking, adhesives, etc. a special function. As far as the current technology is concerned, nano-calcium carbonate generally has problems such as incomplete crystallization, incomplete primary particle development, irregular shape, and wide particle size distribution, which lead to particle coagulation, Agglomeration and other phenomena form secondary particles with larger sizes, and the nano effect is difficult to reflect. Therefore, improving the dispersion of nano-calcium carbonate, reducing the size of secondary particles, and enhancing its compatibility with the application matrix has always been a re...
