摘　　要：利用天然纳米硅酸盐黏土矿物的独特层状结构与晶体表面特性制备出具有纳米三维孔道结构的新型硅铝矿物吸附剂,并对所得纳米多孔材料的性能进行相应的表征及废变压器油吸附再生应用研究,通过吸附再生条件考察确定了最佳吸附条件。对吸附前后变压器油理化性能及电气性能分析结果表明,利用上述吸附剂吸附处理废变压器油后变压器油性能明显改善,耐压性、体积电阻率、界面张力、介质损耗因素、酸值等指标完全符合国家标准,可以实现废变压器油的高效吸附及再生,显著降低了成本,并避免了环境污染及资源浪费。A new type of silicon aluminum mineral adsorbent with three-dimensional pore nanostructures was prepared by using the unique layered structure and crystal surface characteristics of natural nanometer silicate clay minerals.Then the properties of the nano-porous materials were characterized and the regeneration treatment application in waste transformer oil adsorption was studied.The optimum adsorption conditions were determined by investigating the regeneration conditions,and the physical,chemical and electrical properties of transformer oil before and after adsorption were also studied.The results indicated that the performance of regenerated transformer oil was improved obviously after the waste transformer oil was adsorbed and treated by the high efficiency adsorbent.The indexes such as the resistance to voltage,volume resistivity,interfacial tension,dissipation factor and the acid number were in full compliance with the national standard,which can realize efficient adsorption and regeneration of waste transformer oil,and significantly reduce the cost and avoid environmental pollution and resource waste.
