胶体滴定技术与湿部化学过程的控制

全面地阐述了胶体滴定技术的原理;测定纸料中可溶性电解质的阴离子需求量或阳离子需求量的方法和步骤,以及影响胶体滴定结果的诸多因素。胶体滴定比值(CTR)反映了体系中阳离子电荷需求量和阴离子电荷需求量之比,它与造纸湿部过程中的留着率、白水浓度、电导率等有着密切的关系,因此,胶体滴定比值可以表征造纸系统的状态,可以作为控制造纸湿部化学过程的手段

Colloidal Titration Technology and Control of Wet End Chemistry Process

This paper expounds thoroughly the principle of colloidal titration technology, measuring methods and steps of cation or anion demands for soluble electrolyte and effect factors. CTR, which reflexes the demand ratio for positive and negative electric charge,is closely connected with retention, whitewater consistency and electrical conductivity. So CTR can show the state of papermaking system and be a method to control wet end chemistry process.
