通过比较酸洗、碱处理中和、高温煅烧处理等表面处理工艺对磨料工业电弧炉法熔炼制备电熔刚玉型氧化铝填料的影响,分析了不同表面处理方法对氧化铝填料粉体水洗电导率、pH值等性能的影响及对其环氧浇注料流变性能、固化物力学性能的影响.结果表明:酸洗后通过碱处理或煅烧处理均能有效调节环氧浇注的可使用时间及改善环氧浇注固化物的力学性能.
The effects of surface treatment processes such as acid pickling, alkali neutralization, and high-temperature calcination on the fused corundum produced in electric arc furnace for abrasive industry were compared, the effect of different surface treatment methods on the physical and chemical properties such as conductivity and pH value of corundum solution, and the effect of different corundums on the rheological properties and mechanical properties of epoxy casting materials were analyzed. The results show that the corundum neutralized by alkali or treated by calcination after acid pickling could adjust the usable time of epoxy casting material and improve the mechanical properties of the cured epoxy resin.
