摘要:

将微波辐射代替传统水浴加热应用于H2O2麦草浆漂白工艺中。研究了微波辐射时间、辐射功率、H2O2用量和NaOH用量等因素对纸浆漂白效果的影响。通过与传统水浴加热漂白对比发现,达到相应白度时微波辐射漂白时间大大缩短;微波辐射漂白纸浆粘度没有过多下降;微波辐射漂白废水中的残余过氧化物只有水浴漂白的10%。正交实验结果表明H2O2用量的影响最大,其次是微波辐射时间和NaOH用量,影响最小的是微波输出功率。最佳实验条件为微波辐射功率240?W、辐射时间25?min、H2O2用量5%和NaOH用量4%时纸浆白度约为59%ISO,纸浆粘度大于620?mL·g-1,纸浆硬度约为390。

Abstract:

The results of bleaching wheat straw pulp were analyzed using the method of microwave radiation. The results showed that bleaching time, surplus peroxide and the pulp viscosity were lessened compared to bleached pulp of microwave radiation with water bath experiment. The influence of peroxide dosage on bleaching pulp is the most obvious, and the next is irradiation time and NaOH, and irradiation power is the least by orthogonal experiments of four factors. The most optimum conditions are, irradiation power 240W, reaction time 25min, H2O2 5%, and NaOH 4%. The pulp brightness is about 59%, pulp viscosity is more than 620?mL·g-1, and K value is 390.

Key words: microwave irradiation; wheat straw pulp; bleaching
