湿部化学品的发展状况

General Outline of Wet - end Chemicals Development

随着现代造纸工业中高速纸机、双网成形、封闭白水系统、废纸利用和中性造纸等新技术的发展,造纸湿部化学领域的研究与应用取得了令人瞩目的进展。该文系统地论述了湿部化学的基本原理和湿部化学品的发展状况。

The chemistry of the wet-end is changing in response to modern papermaking, i. e, fast machines, twin-wire forming, closed white water system, recycled fibre and the move to neutral or alkaline sizing system. This paper describes the fundamentals of the wet-end chemistry and the development of wet chemicals used in the paper-making.
