摘要
对红麻皮低温ＮａＯＨ—ＡＱ浆常规多段漂白（ＣＥＨ）及少氯短序漂白（ＥｐＨＰ、ＨＡＰ）工艺进行了对比研究。采用ＣＥＨ漂白，总用氯量８％，可漂至８４．４％的白度；采用ＥｐＨＰ漂白，用氯量４％，总Ｈ２Ｏ２用量１．３％，可漂至８５．３％的白度，漂白得率较高，污染负荷较低，漂白浆的各项物理指标均接近漂白木浆的水平，比ＣＥＨ漂白具有明显的优越性。
Minimum chlorine multi-stage bleaching(EpHP and HAP) of LTS-AQ pulp from kenaf bast was studied. The kenaf bast pulp can be bleached to 85. 3% SBD brightness by using EpHP bleaching sequence with a chlorine charge of 4%. total H2O2 charge of 1.3% and NaOH 3%. Pulps bleached with EpHP sequence compared with conventional CEH sequence, EpHP gave a pulp of higher quality, and the bleaching effluents were less pollutive.
