- NaOH-AQ pulp of low Kappa number 低硬度NaOH-AQ浆
- Compared to the conventional kraft(CK) process, EMCC cooking increased pulping selectivity,producing brownstocks with a lower Kappa number and a higher pulp viscosity. 深化脱木素连续蒸煮提高了蒸煮选择性,制得卡伯值较低、粘度较高的纸浆。

- Kappa number is an important quality index of pulp, and it is determined by the quantity of lignin in pulp. 卡伯值是纸浆质量的重要指标,而纸浆中的木素含量决定了纸浆的卡伯值。
- A newmethod for the measurement of the kappa number of Kraft pulp with reflecting spectrum is presented. 提出了采用反射光谱测量纸浆卡伯值的新方法。
- The factors affecting oxygen delignification of fast-growing eucalyptus kraft pulp with kappa number 17. 对卡伯值为17.;1的速生桉木硫酸盐浆进行了氧脱木素各影响因素的研究。
