文摘内容
Peroxide bleaching is an essential unit operation toproduce value-added mechanical pulp-based papergrade. In this paper, we presented the results fromperoxide bleaching of low-freeness TMP for theproduction of SC paper. Two aspects wereaddressed; the effect of pulp strength and theformation of anionic trashes. The strength properties,such as tensile, burst and zero-span tensile, areimproved after the peroxide bleaching process. Theamount of anionic trashes formed is almostproportional to the hydrogen peroxide charge。
