摘　　要：将含有Fe_3O_4或r-Fe_2O_3粉末的黄原酸纤维素钠(粘胶)分散于高速搅拌下的油中,在80～100℃脱水成形,可得粒径<150μm的磁性树脂。研究并论述了磁粉、油类、表面活性剂和搅拌速度等因素对树脂粒径及其分布的影响。The magnetic resin with the particle size of smaller than 150 μm was prepared by stirring an oil suspension of the viscose (sodium cellulose xanthate) containing fine r-Fe2O3 or Fe3O4 at high speed, followed by dehydration and granulation at 80-100℃.The effects of the factors such as magnetic powder, oils, surfactants and the stirring speed on the particle size and distribution of the resin were investigated and discussed.
