| 摘要:本研究以玉米秸秆为原料，通过机械除杂分选、亚硫酸钾法制浆及制浆废液资源化利用，制备了草料、纸浆和黄腐酸肥料，并对纸浆所抄纸张的性能及黄腐酸的结构进行了表征。结果表明，草料（叶与髓）和制浆原料（秸秆硬皮）分别占绝干净料的56%和44%；秸秆硬皮半化学浆得率为60.5%，在纸张定量(125±7) g/m²时，其抗张指数和环压指数分别为38.8 N·m/g和16.4 N·m/g，整体纸张性能优于化学机械浆。半化学法制浆副产物黄腐酸肥料得率为50.0%，其中黄腐酸含量为41%，黄腐酸摩尔质量呈约150和1 600 g/mol的双峰分布。基于1 t绝干净料，可获得草料560 kg、绝干纸浆266.2 kg和黄腐酸肥料220 kg。 |
| Abstract:This study used corn stover as the raw material and produced forage， pulp， and fulvic acid fertilizer through mechanical impurity removal and fractionation， potassium sulfite pulping， and resource recovery of pulping spent liquor. The papermaking properties of the pulp and the structural of the fulvic acid were further characterized. The results showed that forage (leaves and pith) and pulping feedstock (stalk rind) accounted for 56% and 44% of the oven-dry cleaned material， respectively. The semi-chemical pulp produced from corn stalk rind had a pulp yield of 60.5%. At a basis weight of (125±7) g/m²， its tensile index and ring crush index reached 38.8 N·m/g and 16.4 N·m/g， respectively. Its overall papermaking performance was superior to that of the chemi-mechanical pulp. The yield of fulvic acid fertilizer obtained as a by-product of semi-chemical pulping was 50.0%， with a fulvic acid content of 41%. The fulvic acid exhibited a bimodal molar mass distribution， with peaks at approximately 150 and 1 600 g/mol. Based on 1 t of oven-dry cleaned material， 560 kg of forage， 266.2 kg of oven-dry pulp， and 220 kg of fulvic acid fertilizer could be obtained. |
