TAED-activated Peroxides Bleaching of a Chinese Fir CTMP

摘要：

A CTMP pulps made from Chinese fir(Cunninghamia lanceolata)was bleached by hydrogen peroxide,sodium perborate or sodium percarbonate process with TAED as the activator.The TAED-activated peroxide bleaching could be performed at a temperature lower than that of conventional peroxide bleaching.Under the optimized conditions(6％H2O2 or equivalent),the CTMP with an initial brightness of 43.8％ ISO could be brightened to 73.1％ ISO,70.9％ ISO and 69.8％ ISO,respectively,by the H2O2-TAED,perborate-TAED and percarbonate-TAED processes.After bleaching,the tensile,tear and burst indices of the CTMP pulp increased by 48-74％,19-32％,and 37-54％,respectively.The bleached pulp also had higher brightness stability than the unbleached pulp,in terms of post-color number(P.C.).
