Shive content of mechanical pulp (Somerville fractionator) 机械浆的碎片含量(萨默维尔分馏塔)
发布日期: 2015-03-30
这种确定碎片的方法没有尝试对不需要的材料进行详细分类,但是 如果需要,该方法的任何用户都应该能够进行细化。尺寸界限的划分 可接受的来自不良材料的机械浆是任意的;该方法旨在尽可能确保不合格品中不包含任何有用材料,且不存在任何不良材料 接受纸浆。根据该方法检查的亚硫酸盐纸浆的结果约为0.05%希维斯 表明纸浆的拒收部分中含有少量细长纤维。因此,该方法可以是 用于含有机械碎浆的机械浆。
This method for shive determination makes no attempt to classify the undesirable material in detail, but such a refinement should be within the reach of any user of the method if desired. The dimensional limits dividing acceptable mechanical pulp from objectionable material are arbitrary; this method has been designed to ensure as far as possible that no useful material is included in the rejects and that no objectionable material remains in the accepted pulp. Sulfite pulps, examined according to this method, give results in the order of 0.05% shives, an indication that few long fine fibers are included in the rejected portion of the pulp. Accordingly, the method may be used for mechanical pulp containing some machine broke.
