【摘要】 用加入稳定剂的酯类润滑油作为载液,利用化学共沉淀法制备粒径在10nm的Fe3O4作为磁粉,利用表面活性剂在适当的温度条件下高速搅拌得到酯基磁性流体。并对稳定剂的用量及其所起的作用进行了研究。更多还原

【Abstract】 The preparation of synthetic ester based ferrofluids were discused in this paper,which use the synthetic esters combining with some kinds of stable reagents as their carries,use the Fe3O4 nanoparticles(average particle diameter is 10nm) prepared by a chemical co-deposition as magnetic particles,and modified by a kind of composite surfactant,blended in a high speed and a fitable temperature.The effect and dosage of the stable reagents were discussed at the same time.更多还原
