影响废纸浆中大胶黏物测定结果的因素及思考

Factors of Affecting the Measurement of Macro Sticky in Recycled Fiber

造纸工业对二次纤维回用量的依赖一直呈增加趋势,胶黏物(stickies)障碍问题也日趋严重,由于二次纤维和原生纤维常常混用,胶黏物又和树脂混合在一起,增加了生产过程中在设备、织物上的沉积物的复杂性和抄造障碍的严重性,因此如何消除和控制这一障碍就变得尤为重要。本文以废纸制浆生产的二次纤维为研究对象,分离其中的大胶黏物,并结合仪器分析的方法对影响测定浆料中的大胶黏物含量的一些影响因素进行了分析,提出了在实际测试中需要注意的方面。

Recycled fiber plays more and more important role in the paper industry nowadays. Sticky problem together with it becomes a complicated headache also. It has been a serious and sensitive issue for continuous production and quality control. How to determine the actual sticky amount in pulp reliably is a very important precondition controlling this problem. This article demonstrates several influencing factor during the measurement of marco sticky in pulp. Results shows that the bone dry sample amount used for measurement, the disintegration rotation and different coated pick-up paper affect the sticky amount greatly.
