一、引言磁带、磁盘是由γ-Fe_2O_3磁粉分散在粘合剂溶液中经涂布(或甩涂)后制成。无论是为了提高其记录密度,或是改善磁粉与粘合剂的粘附强度,都必须研究和了解磁粉与粘合剂各组分之间的相互作用。问题的实质在于磁粉对磁浆体系中各组分
I. INTRODUCTION Magnetic tapes and magnetic disks are made of γ-Fe 2 O 3 magnetic particles dispersed in a binder solution and coated (or painted). Whether it is to increase its recording density or to improve the adhesion of magnetic powders to adhesives, the interaction between the components of the magnetic powder and the adhesive must be investigated and understood. The essence of the problem lies in the magnetic powder on the components of the magnetic slurry system
