| Abstract: | Polyacrylate composite latex was prepared in enamel kettle by emulsion polymerization.The heat needed in the reaction process was calculated according to the heat balance.The heating effect of steam heating and hot water heating was compared,and the influence of the two heating methods on the particle size of the emulsion and the fouling state of the enamel kettle were also compared.The results showed that compared with hot water heating,steam heating needed shorter heating time,the particle size of the emulsion was smaller,and the fouling of enamel kettle was reduced. |
