造纸纤维和细小纤维的湿部化学特性

Special topical lectures on paper chemicals and wet and chemistry Chapter5:the wet and chemistry performance of fiber and fines

纤维和细小纤维在造纸湿部过程中发生的各种化学的、胶体的、表面的作用,直接影响化学添加剂的效能和纸机的操作。本文从纤维和细小纤维的结构和化学组成入手,主要论述了纤维和细小纤维的湿部化学特性,并重点探讨了打浆度、pH值和铝盐对纤维素纤维动电特性的影响。

As known to all the chemical and colloidal surface reaction between fiber and fines directlyinfluence the effect of chemical additives and runnability of paper machine The wet and chemistry perfor-mance of fiber and fines was discussed in this paper.The structure and chemical constitution,and the influ-ence of beating degree,pH value and alum on their electrokinetic characteristics were discussed in detail.
