【摘要】： 本研究拟开发装饰原纸专用的助留助滤、增强和匀度体系,丰富和发展高填充纸领域的助留助滤理论,并可以给企业一定的技术支持,进一步优化产品质量,降低生产成本。 在实验室规模模拟装饰原纸的生产过程,对单元、双元、多元助留助滤系统的湿部化学行为进行了详细的考察和比较,同时对装饰原纸的匀度、干、湿强度、光学性能和吸收性能等性能指标进行了跟踪检测。实验结果如下： (一)PAE单元系统中,随着PAE用量的加大,纸料的Zeta电位逐渐升高；对于PAE/CPAM和PAE/HCS双元系统,加入CPAM和HCS后,纸料的Zeta电位进一步升高；PAE/APAM双元系统下纸料的Zeta电位随着APAM用量的加大而减小；PAE/CPAM/APAM三元系统中,APAM的加入使纸料的Zeta电位逐渐减小；PAE/CPAM/膨润土微粒系统中,随着膨润土用量的加大,纸料的Zeta电位逐渐减小。 (二)各系统助留助滤效果由好到差依次为：PAE/CPAM/膨润土微粒系统、PAE/CPAM/APAM三元系统、PAE/APAM双元系统、PAE/CPAM双元系统、PAE/HCS双元系统、PAE单元系统和PAE/HCS胶体硅微粒系统。 (三)各系统纸张的干抗张强度由高到低依次为：PAE单元系统、PAE/APAM双元系统、PAE/CPAM/APAM三元系统、PAE/CPAM/膨润土微粒系统和PAE/CPAM双元系统。各系统湿抗张强度由高到低依次为：PAE/CPAM/APAM三元系统、PAE/APAM双元系统、PAE单元系统、PAE/CPAM/膨润土微粒系统和PAE/CPAM双元系统。 (四)各系统纸张的匀度由好到差依次为：PAE单元系统、PAE/CPAM双元系统、PAE/APAM双元系统、PAE/CPAM/APAM三元系统和PAE/CPAM/膨润土微粒系统。 (五)各系统纸张的不透明度和光散射系数由高到低依次为：PAE/CPAM/APAM三元系统、PAE/CPAM/膨润土微粒系统、PAE/APAM双元系统、PAE/CPAM双元系统和PAE单元系统；纸张的光吸收系数由高到低依次为：PAE/CPAM/膨润土微粒系统、PAE/CPAM/APAM三元系统、PAE/APAM双元系统、PAE/CPAM双元系统和PAE单元系统。 (六)各系统纸张的吸液性能由好到差依次为：PAE单元系统、PAE/APAM双元系统、PAE/CPAM/APAM三元系统、PAE/CPAM/膨润土微粒系统和PAE/CPAM双元系统。 综合考虑效果和成本,PAE/APAM双元体系是最佳的选择。
[Abstract]:This study intends to develop a special retention and drainage aid system for decorative base paper, to enrich and develop the retention and drainage aid theory in the field of high filling paper, and to provide certain technical support to enterprises, further optimize product quality and reduce production cost.In laboratory scale simulation of the production process of decorative base paper, the chemical behavior of wet end of unit, double element, multivariate retention and drainage system was investigated and compared in detail. At the same time, the evenness, dryness and wet strength of decorative base paper were also studied and compared.The optical properties and absorption properties were tracked and tested.The results are as follows:(1) the Zeta potential of paper material increases with the increase of PAE content, and for PAE/CPAM and PAE/HCS binary systems, CPAM and HCS are added to the system.The Zeta potential of paper material decreases gradually.(浜，
