对于那些装配有像夹网成形以及复合成形器一类用于生产彩色印刷纸的现代纸机,当以1000m/min车速运行的时候,纸浆将会受到非常强的流体剪切力的作用,使得传统的一元及二元聚合物助留体系很难达到满意的留着效果。为了使灰分较高的纸页在保持更高留着率的基础上增加脱水效率,推动 For modern machines equipped with color printing papers, such as web forming and compound forming, the pulp will be subjected to very strong fluid shear forces when operated at a speed of 1000 m / min such that The traditional one yuan and binary polymer retention system is difficult to achieve satisfactory retention effect. In order to make the higher ash content of the paper to maintain a higher retention rate based on the increase in dehydration efficiency, promote
