浅谈影响纸面石膏板不粘纸的因素及解决方法

Cause and solution to the poor mucosity of facing paper to plasterboard

从纸和板两个方面探讨了纸面石膏板不粘纸的原因,分析了影响石膏板粘结的各种因素。研究发现:护面纸吸水性过高或过低、透气度过低以及强度过低都会对纸面石膏板的粘结产生不利影响;提高石膏粉品位、均化程度和细度,减少有害离子含量有利于纸面石膏板的粘结;合理添加水和外加剂有利于石膏板的粘结。

The paper analyzes the reason and solution on poor mucosity of facing paper to plasterboard.The study educes that the water absorption,low air permeability and low strength of the facing paper will be adverse to the mucosity of plasterboard;Improving the quality of gypsum powder,reducing the harmful ion content,and adding water and admixtures will both be favorable for the mucosity.
