摘 要: 本文研究了湿地松KP浆的完全无氯(TCF)漂白。结果表明,OpXP(X-活化处理)漂序可把纸浆漂至75%(SBD)以上的白度,OXPXP漂序白度可达到90%(SBD)。该工艺的关键是选用了X木素活化剂,经活化的纸浆可漂性大大提高,1%H2O2漂白白度增值可达30%(SBD)以上。 Totally-chlorine-free(TCF) bleaching of slash pine kraft pulp was investigated. The pulp can be bleached to over 75%(SBD) by using OpXP(X-activation treatment) sequence and 90%(SBD) by OXPXP sequence.The key of this technology was the employment of a lignin activating agent. The bleachability of the activated pulp was improved greatly and brightness gain could be as much as 30%(SBD) with 1% H2O2.
