【摘要】 探讨了自制的阳离子有机微粒(CPMP)对漂白阔叶木浆、漂白麦草浆和脱墨废纸浆助留助滤作用的影响。结果表明:各种纸料的一次留着率上升随着CPMP用量的增加而上升,随着转速的增加而减少;CPMP对剪切力和pH值大小不太敏感;CPMP对阔叶木浆的助留助滤效果最好,麦草浆次之,对脱墨废纸浆效果最差。更多还原

【Abstract】 The application as retention and drainage aids on bleached hardwood pulp, bleached wheat straw pulp and deinked wastepaper pulp were studied with a novel cationic polymeric microparticles(CPMP) prepared in lab. The results show the retention and drainage of these pulps improve with the increase of dosage of CPMP, whereas decrease with the increase of stirring speed. The effect of tearing force and pH value on the retention and drainage of CPMP was weak. The effect of CPMP on the retention and draiage of hardwood pulp was better than that of wheat straw pulp, and that of deinked pulp was worst.更多还原
