探讨硫酸钙晶须对纸张强度的增强效果。结果表明,硫酸钙晶须对纸张具有一定的增强作用,当硫酸钙晶须加入量低于10%时,纸页各项强度均有一定程度下降,当加入量高于10%时,纸页各项强度随加入量的增加而升高,硫酸钙晶须加入量为25%时,纸页各项强度达到最大值,继续加入硫酸钙晶须,纸页强度则逐渐下降;纸浆打浆度为50~55°SR时,硫酸钙晶须用于纸张增强的效果最佳。
The effect of calcium sulfate whisker on paper strength is discussed. The results show that the calcium sulfate whiskers have a certain enhancement effect on the paper. When the amount of calcium sulfate whisker is less than 10%, the paper strength decreases to some extent. When the addition amount is more than 10%, the paper sheet The strength increases with the increase of the amount of calcium sulfate whiskers added amount of 25%, the maximum strength of the paper sheet, continue to join the calcium sulfate whiskers, paper strength is gradually decreased; pulp beating degree At 50-55 ° SR, calcium sulfate whiskers are most effective for paper reinforcement.
