【摘要】 探讨了杨木碱性过氧化物机械浆(APMP)在制浆过程中产生的溶解与胶体物质(DCS)对纸浆光学性能、强度性能、滤水和纤维留着性能的影响。结果表明,随着APMP中DCS含量的增加,纸浆的白度、不透明度和光散射系数均有所下降,纸浆的物理强度也随之降低。此外,DCS的存在减弱了阳离子聚丙烯酰胺的作用效果,因而导致纸浆滤水和留着性能的下降。更多还原

【Abstract】 The influences of dissolved and colloidal substances in aspen alkaline peroxide mechanical pulp (APMP) on the optical,physical,retention and drainage properties of the pulp were investigated. The results indicated that,with the increasing of dissolved and colloidal substances (DCS) concentration,the properties of the pulp such as brightness,opacity,scattering coefficient and physical strength decreased. On the other hand,the presence of DCS in the system increased weakened the efficiency of cationic poly acrylamide (CPAM),and led to the decrease of retention and drainage.更多还原
