对比研究了常温脱脂剂及低温磷化工艺与原加温型工艺的处理效果。对卡车货箱电泳涂装生产的前处理工艺进行了常温化改造。在保证产品质量不降低的前提下,涂装前处理中预脱脂及脱脂槽液使用温度由50~55℃降低至25~30℃,磷化槽液温度由40~45℃降低至25~30℃。 Comparative study of the room temperature degreasing agent and the low temperature phosphating process and the original heating process effect. The pretreatment process of electrophoretic coating production for truck cargo box was modified at normal temperature. Under the precondition that the product quality is not reduced, the pre-degreasing and degreasing bath temperature before coating is reduced from 50-55 ℃ to 25-30 ℃, the temperature of the phosphating bath is reduced from 40-45 ℃ to 25-30 ℃.
