介绍了一种新型常温喷淋磷化液。喷淋温度15—35℃,喷淋时间3分钟,磷化膜厚度和重量分别达到2μm和1.7g/m~2以上。磷化膜结晶致密,外观呈均匀一致的灰色。详细陈述磷化工艺流程和工艺条件,给出性能试验结果。常温喷淋磷化液用于黑色金属涂漆前预处理,可明显提高漆膜附着力和整件耐蚀性,适用于合金钢和普通碳钢制品的磷化、涂漆生产线。
Introduced a new type of spray phosphating solution at room temperature. Spray temperature 15-35 ℃, spray time 3 minutes, the phosphate film thickness and weight reached 2μm and 1.7g / m ~ 2 or more. Phosphate film dense, uniform appearance of the gray. Detailed description of the phosphating process and process conditions, performance test results are given. Spray phosphating at room temperature for the pretreatment of ferrous metal paint can significantly improve the paint film adhesion and corrosion resistance of the whole, for the alloy steel and ordinary carbon steel products phosphating paint production line.
