采用等离子体手段,在自行研制的等离子体反应装置上,对常压下气-液两相混合介质进行活化和电离制备纳米磁性润滑油,通过控制脉冲等离子体的放电参数,优化五羰基铁的热解温度,使纳米磁性润滑油反应流程缩短至2个小时左右;制备的纳米磁性润滑油流动性好,纳米磁性颗粒均在10nm左右,饱和磁化强度接近800G(未浓缩)。实验研究表明,等离子体手段能够实现向反应系统提供气-液分子断键复合重新组合所需要的活化能,是加快合成纳米磁性润滑油的一种有效的新方法。
By means of plasma, nanometer magnetic lubricating oil is prepared by activating and ionizing the gas-liquid two-phase mixed medium under normal pressure on a self-developed plasma reaction device. The discharge parameters of the pulsed plasma are controlled to optimize the iron pentacarbonyl The pyrolysis temperature shortens the reaction process of nano-magnetic oil to about 2 hours. The prepared nano-magnetic lubricant has good fluidity, the nano-magnetic particles are about 10 nm and the saturation magnetization is close to 800G (not concentrated). Experimental results show that the plasma method can provide the reaction system with the necessary activation energy to recombine gas-liquid molecular bonds, which is an effective new method to accelerate the synthesis of magnetic nano-oil.
