玉米秸秆皮穰分离后,秸皮采用烧碱-蒽醌法制浆,秸穰经过化学改性后与秸皮浆混合抄纸,大大改善了浆的性能,抗张指数、耐破指数、撕裂指数及耐折度都得到了显著改善。并对改性秸穰的作用机理做了简述。此外,玉米秸穰与浆料混合抄纸,一定程度上可以节约浆纤维,降低生产成本。
After the separation of corn stalk, the stalk was made by caustic soda-anthraquinone pulping method. The stalk was chemically modified and mixed with straw paper, which greatly improved the performance of pulp, tensile index, burst index, tearing Index and folding resistance have been significantly improved. The mechanism of modified straw was briefly described. In addition, corn straw and pulp mixed papermaking, to a certain extent, can save pulp fiber, reduce production costs.
