Abstract

The invention belongs to the pulp and paper making field and particularly relates to a method for rapidly assessing the waste paper pulp adhesive substance control effect. The method for rapidly assessing the waste paper pulp adhesive substance control effect is characterized in that after the waste paper pulp is filtered and intercepted, the content of the intercepted substance, the cation demand, the turbidity and the chemical oxygen demand (COD) of waste paper pulp filtrate can be measured at the same time. The invention is suitable for selecting waste paper pulp adhesive substance control agent / system and assessing the effect thereof and has the advantages of easy operation, rapid measurement speed, and the like.

Description

technical field

[0001] The invention belongs to the pulp and paper industry, in particular to a rapid evaluation method for the control effect of waste paper pulp stickies. Background technique

[0002] Sticky matter control is a major difficulty in the process of waste paper recycling. Stickies refer to the viscous, soft and hydrophobic organic substances that appear in the process of waste paper recycling, mainly derived from tapes and label adhesives, hot melt adhesives, etc. Glue, wax, ink binder, latex, wet-strength resin and other polymers, the accumulation of which will have a great adverse effect on the continuous operation of the paper machine and paper quality, while adding other functional papermaking additives and process properties Consumption of papermaking aids. Solving the problem of the deposition of waste paper pulp stickies is an important direction of current wet-end chemical research. At present, there are many methods such as physical treatment, chem...
