三、聚醚在铝合金淬火件上的应用试验铝合金与钢一样,当淬火时零件会发生变形,特别是厚度小的鈑金件,淬火变形甚大,能否消除或减少淬火变形,省去校形工作,对提高劳动生产率,减轻劳动强度,降低生产成本,具有很大意义。由于聚醚水溶液具有逆溶性,淬火时能在零件表面生成隔离膜,使冷却趋于均匀。同时又可用浓度来控制冷却速度的大小。所以对减小铝合金鈑金件的淬火变形亦当有效。
Third, the application of polyether on the quenching of aluminum alloy test Aluminum alloy and steel, when the parts will be deformed when quenching, especially the small thickness of sheet metal parts, quenching deformation is large, can eliminate or reduce the quenching deformation, eliminating the need for school Shape work, to improve labor productivity, reduce labor intensity, reduce production costs, is of great significance. As polyether aqueous solution has reverse solubility, quenching can generate isolation film on the part surface, so that the cooling tends to be uniform. At the same time can be used to control the concentration of cooling rate of the size. So to reduce the deformation of the quenched aluminum sheet metal parts should also be effective.
