摘要
对杂交狼尾草的化学成分、纤维形态及制浆造纸的可行性进行了研究试验。结果表明:杂交狼尾草的综纤维素含量为79.75%,明显高于麦草,Klason木素含量为17.72%,木素及其他化学成分均比麦草低。纤维长度和长宽比均高于麦草和三倍体毛白杨,壁腔比明显低于麦草但略高于三倍体毛白杨。采用硫酸盐法制浆,其浆张裂断长为7.64km,撕裂指数为6.23mN·m2/g。采用亚铵法制浆,配入50%的国产OCC抄纸,成纸后的各项物理指标均达到了瓦楞原纸的标准要求。
The chemical composition, fibre morphology and feasibility of pulping and papermaking of hybridized Chinese pennisetum was studied in a research trial. The results show that the holocellulose content of hybridized Chinese pennisetum is 79.75%,apparently higher than that of wheat straw and the Klasson lignin content is 17.72%, with the lignin and other chemical composition lower than those of wheat straw. The fibre length and length-width ratio are higher than those of wheat straw and triploid populus tomentosa, and the thecal opening ratio is remarkably lower than that of wheat straw but slightly higher that that of triploid populus tomentosa. For the pulp made with Kraft process, the breaking length of the pulp is 7.64km and the tearing index is 6.23mN· m^2/g. With the ammonium sulfite process pulping, after 50% of homemade OCC being mixed for papermaking, all the physical indices of the finished paper reached the standard requirements for the corrugated medium.
