纸浆、纸和纸板 纤维组成分析 第6部分:纤维粗度测定

[中文适用范围]： 指定确定纤维粗度（这是表征纸浆的纤维特性）的方法：将已知质量的纤维均匀分布在已知区域上，计算沿显微镜载玻片上已知长度的线的纤维交叉数量。 重量系数可以根据纤维粗度来计算。 该方法适用于纤维相对完整的纸浆，如化学浆、半化学浆。 不适用于机械和半机械纸浆或高度打浆的化学或半化学纸浆。 [外文原描述]： Specifies a method for determining fibre coarseness (which is a fibre property characterizing pulp): distribution of a known mass of fibres evenly over a known area, counting the number of fibre crossings along a line of known length on a microscope slide. The weight factor can be calculated from the fibre coarseness. The method is applicable to pulps with relatively intact fibres, such as chemical and semichemical pulps. Does not apply to mechanical and semimechanical pulps or highly beaten chemical or semichemical pulps.
