91视频破解版器塗裝前處置工藝非常重要，一般保守工藝是脫脂、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。

Ultrasonic cleaning machine before coating treatment process is very important, the general conservative process is degreasing, water washing, hydrochloric acid rust removal, water washing, neutralization, water washing, surface conditioning, water washing, phosphating, water washing, drying. The 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，時間不長沿著夾縫呈現鏽蝕現象，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.

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，提高產品噴塗質量，防止塗裝件返鏽方麵，已取得良好效果。

Through the research and practice of ultrasonic cleaning machine technology in phosphating treatment in recent years, good results have been achieved in improving product spraying quality and preventing coating parts from rusting.

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，濕熱條件下夾雜物極易造成工件泛黃、生鏽。

In the process of oil removal, rust removal, water washing, surface adjustment and phosphating, it is difficult to discharge the liquid penetrated in the welding seam, and the water washing can not completely remove it. The inclusions are easy to cause yellowing and rust of the workpiece under hot and humid conditions.

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.

超聲波清洗溫度是影響清洗速度的重要因素，適當提高清洗溫度可增加空化能力、縮短清洗時間，但超越一定溫度，由於蒸氣壓力增加反而降低空化作用，因此必需堅持一定的溫度。試驗標明水溶性介質一般在50℃±5效果佳。

The temperature of ultrasonic cleaning is an important factor affecting the cleaning speed. Properly increasing the cleaning temperature can increase the cavitation capacity and shorten the cleaning time. But beyond a certain temperature, the cavitation effect will be reduced due to the increase of vapor pressure, so it is necessary to adhere to a certain temperature. The test shows that the water-soluble medium is generally good at 50 ℃± 5 ℃.
