摘 要: 研究了纤维素酶对APMP浆的酶处理。通过分析发现,纤维素酶处理可以改善APMP的滤水性能、白度性能,并在一定程度上提高浆的强度性能,并在酶用量0.3U/g绝干浆,纸浆浓度1.0%,温度45℃,初始pH值4.5,时间60min的处理条件下,得到最佳的打浆度改善值,且APMP浆白度和强度指标都有提高。 Research of cellulase treating APMP was carried out. It was proved that cellulase treatment could make drainability and brightness better, and it could improve strength to a certain extent. Under the conditions of dosage 0.3u/gBD, concentration 1.0%, pH value 4.5, 45℃, 60min, the result was the best.
