摘 要: 根据工厂实际情况,采用Pa-H-P漂白流程,主要研究了亚硫酸镁盐法竹子/蔗渣浆的过氧乙酸(Pa)漂白对白度的影响。 According to the paper mill practice,the peracetic acid bleaching(i.e.Pa) of magnesium-based sulfite bamboo/bagasse pulp was studied.The experiment result indicates that the optimal conditions are as follows: temperature 80℃,time 60min,the dosage of Pa and sodium pyrophosphate are 2.0%,0.1%respectively.Under these optimized conditions,the final brightness of the Pa-H-P bleached pulp is up to 80%.
