摘要
对旧报纸碎浆过程中产生的溶解与胶体物质(DCS)对纸浆光学性能、物理强度性能和滤水性能的影响进行了探讨。结果表明,增加DCS含量可降低纸浆白度,当DCS含量为100%时,纸浆白度下降了5.3%ISO。随着体系中DCS含量增加,纸浆的抗张强度、撕裂强度、耐破指数均有所降低。此外,DCS含量的增加亦可降低CPAM作用效果。
The influences of dissolved and colloidal substances released during repalping of ONP on the optical, physical and drainage properties of the pulp were investigated in the paper. The results indicated that increasing the content of DCS would result in the decrease of brightness, and as the content of DCS reached 100%, the brightness of the pulp decreased about 5.3% ISO. With the increasing of DCS, the tensile strength, tear index and burst index of pulp decreased in different degrees. On the other hand, the content of DCS in the system increased could decrease the effect of CPAM on drainage improvement.
