| 摘 要： | 进行了用酸性纤维素酶和中性纤维素酶/淀粉酶与化学处理混合办公废纸的脱墨实验，并优化了酶作用条件。研究表明，用中性纤维素酶/淀粉酶处理的纸浆经浮选后，其纸浆白度比酸性纤维素酶处理和化学处理的浆样分别提高1.9%ISO和1.0%ISO；与化学法相比，用中性纤维素酶/淀粉酶脱墨并用过氧化氢漂白的MOW浆在实验室小长网纸机上抄造的胶印书刊纸白度高、强度好和尘埃度低。实验室研究结果显示了用中性生物酶进行MOW脱墨的优势，为工厂应用该工艺生产高级文化纸提供了可能性。

| Abstract: | Neutral deinking of mixed office wastepaper(MOW) using a combination of neutral cellulase and amylase technology comparied. with an acidic cellulase and conventional chemical technology are conducted, and enzy- matic treatment conditions are optimized It is concluded that the brigtness of deinked pulp treated by neutral cellu- lase/amylase technolgy is 1.9% ISO and 1.0% ISO higher thean those treated by acidic cellulase and conventional chemical method afer floating process respectively. Compared with chemical treatment, printing and writing paper pro duced in 200mm width fourdrinier paper machine with neutral cellulase / amylase; combinations deinked MOW pulp has a higher brightness and physical properties, Iower dirt and ash content. The experimental results indicate the advantage of neutral cellulase/amylase MOW deinking and the feasibility to produce high grade paper in mill scale with the deinking MOW pulp. |
