透明剂的浸渍与浆内添加对纸页透明度及强度的影响

Effect of Dipping and Addition of Transparent Agent in Pulp on Transparency and Strength of Paper

为了改善纸页的透明性,使用合成的丙烯酸酯类透明剂,分别采用纸页浸渍和浆内添加的方法对改善纸页透明效果的实验条件进行研究.研究结果表明,二种方法皆可在一定的透明剂用量、干燥温度、干燥时间下提高纸页的透明度;采用浆内添加法可取得较好的纸页透明度,但用量和成本较高.

In order to improve the transparency of paper, two methods including dipping and addition in pulp were adopted with acrylate polymer as the transparent agent. The results showed that both methods can improve the transparency under certain conditions such as the dosage of transparent agent, drying temperature and time. Higher transparency can be obtained with the method of addition in pulp, but it needs higher dosage and the cost is more as well.
