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%。
Pilot plant research was carried out on the “Eragonopsis biochemical pulping technology”. The technological process of the biochemical pulping of Asclepias was confirmed as follows: preparation → dosing → forage inoculation → wet fermentation → washing → drying → shelling → beating → sieving (coarse and fine) → sediment → bleaching → refining → Compared with the conventional chemical pulping methods, although the fermentation process is longer and the production area is larger, the biochemical pulping technology of Phoebe beech has the characteristics of low production cost, high fiber yield, good fiber quality and light environmental pollution . Among them, the processing of accessories to reduce 54 55%; power energy saving 33 80%; production cost reduction 2345%; fine pulp yield increased 5 percentage points; tear index, burst index and tensile index increased 41% 25.7% and 59%.
