摘要
研究CPAM/CMC两种聚电解质层间自组装对废旧瓦楞纸(OCC)浆强度性能的影响,对层间自组装过程中浆料的Zeta电位变化进行了测试,并借助扫描电镜(SEM)和傅里叶红外光谱(FT-IR)对吸附聚电解质的OCC纤维表面进行了分析。结果表明,CPAM/CMC自组装对纸页的增强效果较好,裂断长、耐折度及环压指数分别提高了82.82%、550.00%、92.88%,浆料滤水时间减少,滤水性能明显改善。浆料Zeta电位随聚电解质自组装层数的增加而不断变化,表明纤维表面自组装过程源于阳离子和阴离子聚电解质的静电作用力。SEM、FT-IR表征显示,纤维表面确实吸附有聚电解质复合物。
The influence of CPAM/CMC layer-by-layer self-assembly on OCC fibre physical strength and surface properties was discussed, and the zeta potential of self-assemblied fiber was characterized, and the surface properties of fiber samples were characterized by SEM and FTIR techniques. It was shown that the physical strength and draining property of recycled fiber were improved 82.82%, 550.00%, 92.88% and 48.00% with the increase of CPAM/CMC self-assemblied layers. It was (ound that fiber Zeta potential was changed with the layers of polyelectrolyte. According to the results of SEM and FTIR, it was inferred that polyelectrolyte was absorbed onto the fiber surface.
