纸张在纸机上的成形以及各种分离过程(如白水盘中纤维的回收)均建立在含纸浆和助剂的悬浮液过滤的基础上。过滤性能通过脱水效率来表征,而脱水效率取决于纸浆悬浮液成分的性能。比表面积高的细小颗粒会堵塞滤饼、降低脱水效率。木材原料(单根纤维、原始细小纤维以及二次细小纤? The formation of the paper on the paper machine and various separation processes (such as the recovery of the fibers in the white water tray) are based on the filtration of the suspension containing pulp and auxiliaries. The filtration performance is characterized by the efficiency of the dehydration, which depends on the properties of the pulp suspension composition. Fine particles with high specific surface area will clog filter cake and reduce the efficiency of dehydration. Wood raw materials (single fiber, the original fines and secondary finer?
