BS ISO 302:2015规定了纸浆卡伯值的测定方法。这个 卡伯值是木素含量或纸浆可漂性的指标。本国际标准适用于中国境内的各种化学浆和半化学浆 卡伯值在1到100之间。对于卡伯值超过100的纸浆，使用氯消耗法 描述脱木素程度的程序（ISO 3260）。为了达到最大的精度和准确度，必须调整样本大小，以便 高锰酸盐的消耗量在添加量的20%到60%之间。 注:卡伯值和木质素含量之间没有一般明确的关系 果肉。这种关系因木材种类和脱木素程序而异。所有化合物 被高锰酸钾氧化，不仅木质素，还会增加高锰酸钾的消耗，从而增加卡伯值 数字[8] 如果要用卡伯值来推导纸浆木质素含量的指数，则需要特定的关系 必须针对每种纸浆类型进行开发。交叉引用:ISO 638ISO 7213ISO 3260ISO/TR 24498购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 302:2015 specifies a method for the determination of the Kappa number of pulp. The Kappa number is an indication of the lignin content or bleachability of pulp.This International Standard is applicable to all kinds of chemical pulps and semi-chemical pulps within the Kappa number range 1 to 100. For pulps with a Kappa number exceeding 100, use the chlorineconsumption procedure (ISO 3260) to describe the degree of delignification.To achieve the greatest precision and accuracy, the sample size has to be adjusted so that the consumption of permanganate falls between 20 % and 60 % of the amount added.NOTE There is no general and unambiguous relationship between the Kappa number and the lignin content of pulp. The relationship varies according to the wood species and delignification procedure. All compounds oxidized by KMnO4, not only lignin, will increase the consumption of KMnO4, and thereby increase the Kappa number.[8] If the Kappa number is to be used to derive an index of pulp lignin content, specific relationships will have to be developed for each pulp type.Cross References:ISO 638ISO 7213ISO 3260ISO/TR 24498All current amendments available at time of purchase are included with the purchase of this document.
