Method for recovering nanometer ceramic particles in magnesium-based composite material
The invention discloses a method for recovering nanometer ceramic particles in a magnesium-based composite material, and relates to the field of nanomaterial manufacturing. The invention aims to solve the problem that after nanometer ceramic particle reinforced magnesium-based composite materials loses efficacy, high-content reinforcements in the nanometer ceramic particle reinforced magnesium-based composite material cannot be reutilized and a large amount of resources are wasted. The method comprises the following steps: heating and melting a failed magnesium-based composite material containing nanometer ceramic particles; mixing and grinding sodium chloride, potassium chloride and calcium fluoride, adding the obtained mixture into a magnesium alloy melt, conducting stirring, then performing standing, and carrying out water cooling on a crucible containing a metal melt and molten salt; finally, soaking a cast ingot in an aqueous solution for a period of time so as to obtain turbid liquid containing the nanometer ceramic particles; and washing the turbid liquid multiple times to realize the recovery of the nanometer ceramic particles. The method is a simple and efficient reinforcement recycling technology. The method has huge economic benefits for recycling the nanometer ceramic particles with high additional value. The method is applied to the field of material recovery.
一种镁基复合材料中纳米陶瓷颗粒的回收方法，它涉及纳米材料制造领域。本发明要解决由于纳米陶瓷颗粒增强镁基复合材料在失效后，其内部高含量的增强体不能二次利用，造成大量资源浪费的问题。本发明将失效的含有纳米陶瓷颗粒的镁基复合材料加热熔化；将氯化钠和氯化钾，氟化钙混合研磨，将其添加到镁合金熔体并搅拌，然后静置，将含有金属熔体和熔盐的坩埚水冷。最后将铸锭浸泡在水溶液中一段时间，得到含有纳米陶瓷颗粒的悬浊液。将悬浊液多次洗涤后实现纳米陶瓷颗粒的回收。本发明是一种简单高效的增强体回收利用技术。对高附加值的纳米陶瓷颗粒的回收利用有巨大的经济效益。本发明应用于材料回收领域。
