| 摘 要： | 研究脂肪酶对激光打印废纸的脱墨作用，优化脂肪酶脱墨的工艺条件，并与中性脱墨与碱法脱墨进行比较．结果表明，激光打印废纸的脂肪酶脱墨优于中性脱墨与碱法脱墨．脂肪酶脱墨的最佳工艺条件是：碎浆浓度10％～12％，碎浆温度55℃，碎浆时间40min，酶用量0．03％，浮选时间8min．在适宜的脱墨条件下可使脱墨浆ISO白度达到93．42％，残余油墨面积为O．01％．

| Abstract: | Lipase deinking of Laser-print wastepaper was investigated in this study. Then deinking process of Laser-print wastepaper with lipase was optimized and deinking efficiency between lipase deinking,neutral deinking and alkaline deinking was compared. Results show that Laser-print wastepaper with lipase deinking is better than that with neutral deinking and alkaline deinking. The optimized deinking conditions are ：pulping consistency 10% - 12%,pulping temperature 55 ℃ ,pulping time 40 min ,enzyme dosage opposite in dry pulp 0.03%,floating time 8 min. By using the optimized conditions,the deinking pulp brightness can reach 93.42%ISO,the residual ink area is 0.01%. |
