| 摘 要： | 利用碱性物质与H2O2在适当加热条件下能够发生剧烈反应并释放热能的原理,研究了NaOH和KOH两种制浆工艺对黑液性质和纸浆性能的影响。通过考察碱用量、H2O2用量、投料间隔时间及蒸煮时间对黑液的COD、色度及纸浆的高锰酸钾值、白度和得浆率等的影响,确定了草浆造纸清洁制浆最佳工艺条件。结果表明,NaOH制浆的最佳工艺条件为：NaOH用量11%（所述药品为100%含量,用量指占稻草原料质量的比例,下同）、H2O2用量18%、投料间隔1 h、蒸煮时间2.5 h;KOH制浆的最佳工艺条件为：KOH用量10%、H2O2用量18%、投料间隔30 min、蒸煮时间2 h。对比两种工艺所得纸浆及其产生黑液的性质,表明KOH清洁制浆效果明显优于NaOH。

| Abstract: | Based on the theory that alkaline substances can vigorously react with H2O2 and give off considerable heat,effects of NaOH and KOH pulping processes on black liquid properties and pulp properties were investigated.Influence factors such as alkali dosage,H2O2 dosage,feeding time interval and total cooking time were studied against properties of black liquor(COD,color) and pulp(potassium permanganate value,pulp brightness and pulp productivity),and the optimal clean pulping process for papermaking was determi... |
