纸浆卡伯值测定方法的研究进展

The Research Progress of Kappa Number Testing Method

传统化学法测定卡伯值步骤复杂、时间长、误差较大,很多研究者都在探索新的测定方法。本文介绍和评价了近年来出现的几种直接和间接的纸浆卡伯值分析法,重点介绍了新开发的卡伯值快速测定法。

Kappa number of pulp is an important property to pulping and bleaching. The manual titration-based kappa number testing method is complicated and time-consuming, and easy to introduce human error in the testing. The purpose of this paper is to introduce and evaluate several advanced instrumental methods recently developed for pulp kappa number testing. It will be helpful to better understand these new kappa number testing techniques.
