废纸浆湿部体系电导率的演变规律及其成因分析
Evolution and cause analysis of electrical conductivity in wet-end system of recycled pulp
摘要
Abstract
The conductivity of white water in the recycled paper making system is the key fac-tor affecting the efficiency of wet-end additives and the main technical difficulty in wet-end control of recycled paper recycling.This article explores the factors affecting the conductivity of white water in recycled paper pulp by simulating the closed cycle of white water during the papermaking process.The experimental results indicate that the closed cycle of the white wa-ter system in recycled pulp papermaking will lead to a significant increase in the conductivity of the white water.The accumulation of inorganic salts is one of the reasons for the increase in conductivity of white water,but when inorganic salts accumulate to dynamic equilibrium,the increase in conductivity caused by inorganic salts does not exceed 5%of the initial con-ductivity.Under the closed cycle of white water,the organic electrolyte formed by starch deg-radation and deterioration is the main cause of the continuous increase in the conductivity of white water in recycled pulp.Low temperature and fungicide treatment can effectively sup-press the increase in the conductivity of circulating white water.关键词
