废纸脱墨过程中纤维特性的变化分析

Change of Recycled Fiber Characteristics in Deinking Process

以广州造纸有限公司的生产线为例,观察分析了新闻纸用废纸脱墨过程中,二次纤维表观形态的变化过程以及胶体化学特性。

Secondary fiber characteristic is an important factor affecting both paper quality and fiber recycling system. It is also related to fiber physical properties and its colloidal chemistry. This article analyses the characteristic change of secondary fiber in the waste paper treating processes of an industrial fiber line, and the Zeta potential, conductivity, fiber morphology and fiber length distribution were investigated in the whole recycling process.
