摘要
以过氯乙烯氯化液为原料，研究了氯化液喷雾脱挥工艺，取得了良好的效果。试验条件下，氯化液中的氯苯脱除率达到98．7％以上，热水中氯苯质肇浓度小于25mg／L，是现有工艺的6％～15％；喷雾脱挥形成的树脂颗粒的Sauter平均粒径（SMD）为70～150μm，粒径的累积体积分布符合Rosin-Rammler分布。对得到的过氯乙烯树脂进行质量检测，结果表明，树脂质量部达到了产品要求的质量标准。
The devolatilization process with chlorination liquid of chlorinated polyvinyl chloride as raw material by the atomization technology was studied, and good results were obtained. Under experimental conditions, the removing ratio of chlorobenzene from chlorination liquid could exceed 98.7 %, the concentration of chlorobenzene in the hot water could be less than 25 mg/L, which was 6% - 15% of chlorobenzene content achieved in the present process; the Sauter mean diameter （SMD）of the resin particle obtained was between 70 - 150 μm, the particle size distribution agreed with Rosin-Rammler distribution. The quality of the resin was tested, the results showed that the produced resins could measure up to the quality standard of the product.
