摘要：
通过对我厂两个循环冷却水场近几年来低浓度预膜、不预膜及在生产运行中期预膜（补膜）实践过程的分析，探讨了以提高预膜质量来延长生产周期的可行性。
Abstract:
Based on our two cooling water circulation field in recent years, low concentration of preparing membrane, not film and in the middle of the production run pre membrane (for film) the analysis of the practice process, in order to improve the quality of preparing membrane is discussed to prolong the feasibility of the production cycle.
