摘 要: 在新闻纸纸料系统中 ,树脂是机械浆 (包括磨石磨木浆和热磨机械浆 )的有害组分之一 ,树脂障碍也是新闻纸厂必须面对的一个重要问题。随着新闻纸厂白水封闭程度的日益提高 ,树脂积累的问题也得到了普遍的关注。此外脱墨浆的采用也会引入一部分对系统不利的物质。本研究采用了一种机械分散方法制得了呈胶体态的树脂成分 (CRC ,ColloidalResinComponent)模拟物 ,并在试验基础上分析和探讨了CRC对新闻纸成纸的抗张强度、撕裂度。 Resin is the main component of wood extract, which is harmful to the paper quality especially in newsprint. In the case of mill whitewater closure, the problems become more noticeable. In this work, the CRC (colloid resin component) model compound was made by individually dispersing the oleic acid and glyceride with a mechanic method, and the effects in newsprint physical proprieties and mechanism were discussed
