今天91视频下载安装來講講91视频破解版在磷化處理與塗裝處理的應用，經過近幾年對91视频破解版技術在磷化處理中的研究實踐，在提高產品噴塗質量和防止塗裝件返鏽方麵，已取得良好效果。

Today we are going to talk about the application of ultrasonic cleaning machine in phosphating treatment and coating treatment. Through the research and practice of ultrasonic cleaning machine technology in phosphating treatment in recent years, we have achieved good results in improving product spraying quality and preventing coating parts from rusting.

一般傳統工藝是脫脂、水洗、鹽酸除鏽、水洗、中和、水洗、表調、水洗、磷化、水洗、烘幹。此工藝很大弊端是對結構複雜零件酸洗除鏽後的殘酸很難衝洗幹淨，尤其是焊接組合件磷化後，其夾縫內含有的殘液影響後道工序的加工。

The general traditional process is degreasing, water washing, hydrochloric acid derusting, water washing, neutralization, water washing, surface conditioning, water washing, phosphating, water washing and drying. The major disadvantage of this process is that it is difficult to clean the residual acid after pickling and derusting the parts with complex structure, especially after phosphating the welding assembly, the residual liquid contained in the crevice affects the processing of the next process.

工件噴塗後，時間不長沿著夾縫出現鏽蝕現象，波壞塗層表麵。嚴重影響產品外觀和內在質量。如摩托車車輪、油箱、車架、防盜門等。

After spraying, the workpiece will rust along the crack for a short time, and the coating surface will be damaged. Seriously affect the appearance and internal quality of products. Such as motorcycle wheels, fuel tank, frame, security door, etc.

91视频破解版漂洗是工件在除油、除鏽、水洗、表調、磷化等工藝中滲透在焊接夾縫內的液體很難排出，且水洗不能完全清除幹淨，在濕熱條件下夾雜物極易造成工件泛黃、生鏽。

Ultrasonic cleaning machine rinsing is the process of removing oil, rust, water washing, surface adjustment, phosphating, etc. it is difficult to discharge the liquid in the welding seam, and the water washing can not completely remove it. Under hot and humid conditions, inclusions are easy to cause yellowing and rust of the workpiece.

如果這些殘液在烘幹過程中不能完全幹固，隨後粉末噴塗以高溫烘幹時，殘液由於熱膨脹的作用將滲出焊縫，影響塗料與金屬表麵的結合，造成塗層的附著力下降甚至脫離。

If the residual liquid can not be completely dried in the drying process, then when the powder spraying is dried at high temperature, the residual liquid will seep out of the weld due to the effect of thermal expansion, which will affect the combination of the coating and the metal surface, resulting in the decrease or even detachment of the coating adhesion.
