APMP酶促打浆节能研究

A study on energy-saving of enzyme-aided refining on APMP

研究了纤维素酶、木聚糖酶处理对速生杨APMP浆的影响。探讨了酶用量、pH值、温度、时间等因素对浆能耗、成浆强度性能和光学性能的影响。结果表明:经过酶处理,浆料的纤维结构变得更疏松,使纤维快速润胀,强化纤维间结合力,显著降低打浆能耗,并有效改善机械浆强度性能和光学性能。通过对比实验发现,纤维素酶在降低打浆能耗、改善物理强度方面较理想,在改善白度性能方面,木聚糖酶效果要优于纤维素酶。

The effect of cellulase and xylanase treatment on fast-growing poplar wood APMP was studied. The effects of the factors influencing the pulp energy consumption, pulp physical strength properties and optical properties such as enzyme dosage, pH, temperature and time were studied. The results show that the fiber structure gets looser, the fiber swells fast, the interfibre bonding force gets stronger, the energy consumption decreases remarkably and the physical properties and optical properties of the MP were improved effectively. It was found that cellulase was better in physical properties improvement and energy consumption reduction and xylanase was better in raising the brightness properties.
