摘要
对比研究了含-SO3Na基团和不含-SO3Na基团的聚氨酯磁带胶的沉降高度及电镜照片, 结果均证明含-SO3Na基团的聚氨酯磁带胶对磁粉的分散性有显著提高.
The electronic microscope photographs of magnetic tapes using polyurethane(PU) with and without SO3Na groups as binder,and the sedimentary heights of magnetic powder in the PU binder were studied.The dispersion effect of magnetic powder in PU binder with-SO3Na groups was much better than that without-SO3Na groups.
