摘　　要：利用烧碱-蒽醌碱法制浆工艺对育种田汉麻芯秆和纤维田汉麻芯秆进行蒸煮,研究用碱量对二者成浆性能的影响。结果表明,当蒸煮温度160℃、保温时间2.5 h时,随着用碱量的增加,2种浆料的粗浆得率和高锰酸钾值逐渐下降,纤维素含量和保水值逐渐提高;当用碱量为20%时,育种田汉麻芯秆浆和纤维田汉麻芯秆浆的粗浆得率分别为48.3%和56.8%,高锰酸钾值分别为11.0和13.9,纸浆得率和性能相对较优。将打浆度均为40°SR的这2种汉麻芯秆浆(纤维长度约1~3 mm)分别与针叶木浆(打浆度40°SR)按一定配比混合抄纸发现,配抄5%汉麻芯秆浆可改善纸张的强度性能,表明汉麻芯秆浆可作为生产箱纸板面层纸或牛皮纸等的替代原料。Caustic soda-anthraquinone alkaline pulping was carried out using core stalks of breeding hemp and fiber-field hemp as raw materials,and effect of alkali amount on the pulping properties was investigated.The results showed that the brown pulp yield and potassium permanganate value gradually decreased while cellulose content and water retention value increased with increasing alkali amount.The brown pulp yields of core stalks of breeding hemp and fiber-field hemp were 48.3%and 56.8%,potassium permanganate values 11.0 and 13.9,respectively,when alkali amount was 20%;both pulp showed decent yield and properties.The two hemp core stalk fibers with length of 1~3 mm moderately improved physical properties of paper when respectively mixed(amount of 5%)with softwood pulp fibers(beating degree=40°SR).Therefore,the as-prepared hemp core stalk pulp can be used as an alternative raw material for producing cardboard top layer or kraft paper,etc.
