摘　　要：探讨了甲脒亚磺酸(FAS)用于杨木碱性过氧化氢化机浆(APMP)漂白时, FAS用量、NaOH和FAS用量比、浆浓、漂白温度和时间对漂后纸浆白度的影响,通过实验得出最佳工艺条件:FAS用量0.6%(对绝干浆的质量分数),漂白浓度10%,温度70℃,时间60min,FAS与NaOH用量比为2,得到漂白浆白度为62.3%SBD,白度提高了9.8%SBD。通过对Na2S2O4、H2O2单段漂白的研究,从纸浆白度、强度、废水污染负荷和工艺条件等方面与FAS漂白效果进行了比较,得出FAS是一种较清洁和经济的新型漂白剂。Bleaching of poplar APMP by formamidine sulphinic acid(FAS) is investigated in this paper.The effects of FAS dosage, ratio ofNaOH to FAS, stock compound, bleaching temperature and time on brightness gain,color reduction and pulp strength are studied.The bleachedpulp with brightness 62.3%(SBD) has made on the best technical conditions of the 10% pulp consistency, 60 minutes and 70℃, an FAS solutioncontaining 0.6%(on o.d.pulp) and ratio of NaOH to FAS 2.It has been conclued that FAS is an effective and potential bleacher by a study onsingle-staged bleaching of Na2S2O4 and H2O2.
