| 摘 要： | 不同总铝浓度和碱化度的聚合氯化铝在助留助滤方面没有明显差别。聚合氯化铝与两性淀粉或阳离子聚丙烯酰胺协同作用,能显提高漂白麦草浆纸料的一次留着率及其滤水性,并且在中、碱性条件下可达到较好的留着效果。此外,搅拌速度和接触时间对漂白麦草浆的一次留着率有不同程度的影响。

| Abstract: | There is no significant difference in efficiency as retention and drainage aids among the polyaluminum chlorides(PAC) of different total aluminum concentration and basicity. PAC can greatly improve the first pass retention(FPR) and drainage of the stock cooperating with amphoteric starch or cationic polyacrylamide(CPAM) and will have a better effect on retention along with the use of amphoteric starch or CPAM in neutral and alkaline pH. The retention is also affected by agitating speed and reaction time in varying degrees. |
