龙须草生物化学制浆的中试研究

Pilot Trial of Bio-Chemical Puling of Eulaliopsis Binata

对“龙须草生物化学制浆技术”进行了中试研究。确定了龙须草生物化学制浆的工艺流程为 :备料→配液→草料接种→湿润发酵→洗涤→轧干→脱壳→打浆→筛浆 (粗、细 )→沉渣→漂白→磨浆→制板 ;与常规化学制浆方法相比 ,龙须草生物化学制浆技术虽然发酵周期较长 ,生产场地较大 ,但具有生产成本低、纤维产量高、纤维品质好和环境污染轻等特点。其中 ,工艺辅料减少 54 55 % ;动力能耗节省33 80 % ;生产成本降低 2 3 45 % ;细浆得率提高 5个百分点 ;撕裂指数、耐破指数和抗张指数分别提高 41 %、2 5 7%和 5 9%。

This article described the pilot trial of bio-chemical pulping of Eulaliopsis Binata.The process was :material preparation→bacteria solution preparation→inoculation→fermentation→washing→squeezing→shell-releasing→beating→pulp→screening→residue depositing→bleaching→refining→pulp board making.Compared with traditional chemical process,the new one required a longer period for fermentation and more workshop,but it was of advantages such as low cost,high output and fiber quantity,low pollution and etc.The auxiliary reagent demand,energy consumption and cost was reduced by 54.55%,33.80%and 23.45% respectively.The tear index,burst index and the tensile index was increased by 41%,25.7% and 5.9% respectively.The screened pulp yield could be increased by 5 percentages.
