摘要
结合石膏晶须的结构性能和特点,对石膏晶须溶解抑制改性进行初步研究.分析石膏晶须经改性剂TSNG改性后溶解度的变化,并研究添加改性晶须后纸页白度、相关强度性质及填料留着率的变化情况.实验结果表明:采用改性剂TSNG对石膏晶须改性后可有效降低石膏晶须的溶解度;添加改性石膏晶须的纸页能取得较好的白度,但纸页强度有一定程度的降低.
The dissolving inhibition of gypsum whiskers in water was studied based on the structure and characteristics of gypsum whisker. TSNG was adopted as the inhibitor to reduce the solubility of the whiskers. The changes of the solubility of whiskers,the brightness and the strength of papersheet after filling the modified whiskers,and the retention of the whiskers as fillers were investigated in detail. The experimental results showed that the inhibitor TSNG can reduce the solubility of gypsum whiskers effectively. The papersheets filled with modified gypsum whiskers can keep high brightness,while the strength was reduced to a certain extent.
