| 摘 要： | 研究了Na+、Ca2+和Al3+及其和阳离子聚合物对杨木化学热磨机械浆(CTMP)中溶解与胶体物质(DCS)的稳定性影响.结果表明,金属离子使DCS的稳定性下降,而且价数越高,DCS失稳需要的用量越少.其中Al3+对DCS稳定性的影响还受到体系pH值和Al3+浓度的影响.一定含量的金属离子能促进阳离子聚合物对DCS的失稳作用.

| Abstract: | The effect of Na+,Ca2+,Al3+ and cationic polymers on the stability of dissolved and colloidal substances(DCS) released from aspen chemithermomechanical pulp(CTMP) was investigated.The results showed the existence of metal ions led to the decrease of stability of DCS.The higher of the valence,the less of the dosage which led to the destability of DCS.In addition,the concentration of Al3+ and the pH also affected the destabilizing ability of Al3+ on DCS.Metal ions could promote the destabilizing ability of ca... |
