1·Zinc dross is the most important factor impairing the surface quality of the hot dip galvanized steel sheets.
锌液中的锌渣是影响热镀锌钢板表面质量的重要因素。
2·Experiment manifests that the leaching rates of zinc dross are elaborately enhanced and the leaching time of zinc oxide finished ore is shortened by means of ultrasonic strengthening.
试验表明利用超声波强化浸出锌浮渣可大大提高了锌浮渣的浸出率，缩短了浸出时间。
3·The recovery of hot galvanizing dross was paid more attention along with the decreasing of original raw zinc resource.
随着锌矿原生资源的日益减少，锌渣的回收问题越来越受到人们的重视。
