以废纸为原料生产挂面纸板会给造纸厂带来许多问题。如果不进行适当控制,就会引起产品质量下降,并影响纸机正常运行。为解决废纸造纸带来的诸多问题,科研工作者进行了广泛的研究并开发出了许多新技术方法,如纤维分级、磨浆前用酶处理回收纤维、表面施胶和Condebelt干燥等。近来 Using waste paper as raw material to produce linerboard brings many problems to the paper mill. If not properly controlled, it will cause product quality decline, and affect the normal operation of the paper machine. To solve many problems caused by waste papermaking, researchers carried out extensive research and developed many new techniques and methods, such as fiber grading, enzyme treatment of recycled fibers prior to refining, surface sizing, and Condebelt drying. recently
