摘　　要：研究了纤维素酶对非接触印刷纸脱墨的影响。结果表明，在脱墨过程中加入纤维素酶可以提高脱墨效果，所得脱墨浆白度高，残留油墨少，滤水性能好。如果非离子表面活性剂和酶制剂同时使用，效果更佳，可以实现在中性条件下脱墨。The effects of cellulase on deinking of nonimpact printed papers were investigated in this paper.It has been found that enzyme can enhance the deinking efficiency.The enzymedeinked pulps have higher brightness,lower dirt content and better drainage property.If nonionic surfactant is used along with the neutral enzyme,the neutral deinking process,which was believed can reduce environmental pollution,can be realized.In the meantime,mechanism of enzymeenhanced deinking was discussed.
