Abstract
This method is based on interm ittent carbonization method for preparation of nanometer calcium carbonate. It adopts piezoelectric ultrasonic assisted synthesis method, aims to realize industrialized production of high quality nanometer calcium carbonate, settles synthetic reaction tank structure and the design of synthetic gear system of nanometer calcium carbonate under ultrasound irradiation, and discusses the relationship between the influence factors and nano calcium carbonate particle size under ultrasonic irradiation process. The graph indicates the relationship between the heat transfer of reaction system , mass transfer effect and the particle size. The results show that the main factors affecting the particle size are initial tem perature of slurry, Ca (OH )2 slurry em ulsion concentration, and flow rate of CO2. In a homemade device, the high quality nano calcium carbonate products of 10 ~ 30 nm are produced, and this provides another method for the production of nanometer calcium carbonate powder.关键词
