研究了碱性过氧化氢预处理热磨机械浆(TMP)浆渣的效果。结果表明,当总碱为5.2%时,碱性过氧化氢预处理使磨浆的单位能耗降低了20%,并符合所要求的游离度,还提高了纸张的紧度和抗张强度;预处理的不利方面是光散射系数和纸浆得率有所下降。
The effect of alkaline hydrogen peroxide pretreatment on hot pulping of mechanical pulp (TMP) was studied. The results showed that when the total alkali was 5.2%, the pretreatment with alkaline hydrogen peroxide reduced the unit energy consumption of the refining by 20% and satisfied the required freeness and also increased the paper tightness and tensile strength. Disadvantages of pretreatment are the decrease of light scattering coefficient and pulp yield.
