摘　　要：以大型文化纸机实际白水作为研究对象,研究短循环白水中溶解胶体物(Dissolved and Colloidal Substance,即DCS)的控制。单一的聚合氯化铝(PAC)对白水中DCS含量控制没有明显效果;少量聚胺(PA)配合PAC能对白水中DCS含量具有明显控制效果,使纸料系统的保留和纸张品质得到改善,同时使纸机具有良好的运行状况。The control of dissolved colloidal substance （DCS） in white water from the fine paper machine was investigated. The results showed that single poly-aluminum chloride （PAC） had no obvious effect on the control of DCS amount in white water. A small amount of polyamine （PA） with PAC had a significant effect on the control of DCS amount in white water. It improved the retention of the system and the quality of the paper. Meantime, it made the paper machine had a good working condition.
