摘　　要：采用漆酶-组氨酸的组合方式处理OCC浆,并先后在实验室和纸厂研究此生物处理方式对瓦楞原纸性能的影响。实验室小试研究结果表明,当漆酶和组氨酸的用量分别为0.90 U/g和1.0%(对绝干浆)时,成纸的干湿环压指数分别提高了22.9%和30.3%。中试结果也表明,漆酶和组氨酸用量分别为0.225 U/g和0.10%时,成纸干湿环压指数分别提高14.9%和26.4%,纵横向抗张指数分别提高8.0%和10.7%,耐破指数提高16.4%。同时生物处理在促进纤维分丝帚化方面也有明显效果,经处理的纤维保水值上升了40个百分点,纤维平均孔径和比表面积分别提高了1.1%和5.1%,并且浆料中羧基含量也提高了35.4%。In this paper,the influence of laccase-histidine on OCC fiber proterties was studied both in laboratory and mill.The laboratory results showed that when the amounts of laccase and histidine were 0.90 U/g and 1.0% respectively.The dry and wet ring crush index of papersheet increased by 22.9% and 30.3% compared with the control sample.Furthermore,the pilot test results also showed that when the amounts of laccase and histidine were 0.225 U/g and 0.10%（on oven dried pulp）,the dry and wet ring crush index of papersheet increased by 14.9% and 26.4%,the longitudinal and cross tensile index increased by 8.0% and 10.7%,and brusting index increased by 16.4%,correspondingly.Besides,fibrillation was greatly developed and water retention value（WRV） increased by 37.5%.At the same time,the average pore size of fiber wall,specific surface area and carboxy group content increased by 1.1%,5.1% and 35.4% respectively.
