今天我們來(lái)講講超聲波清洗機(jī)在磷化處理與涂裝處理的應(yīng)用,經(jīng)過(guò)近幾年對(duì)超聲波清洗機(jī)技術(shù)在磷化處理中的研究實(shí)踐,在提高產(chǎn)品噴涂質(zhì)量和防止涂裝件返銹方面,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(tǒng)工藝是脫脂、水洗、鹽酸除銹、水洗、中和、水洗、表調(diào)、水洗、磷化、水洗、烘干。此工藝很大弊端是對(duì)結(jié)構(gòu)復(fù)雜零件酸洗除銹后的殘酸很難沖洗干凈,尤其是焊接組合件磷化后,其夾縫內(nèi)含有的殘液影響后道工序的加工。
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.
工件噴涂后,時(shí)間不長(zhǎng)沿著夾縫出現(xiàn)銹蝕現(xiàn)象,波壞涂層表面。嚴(yán)重影響產(chǎn)品外觀和內(nèi)在質(zhì)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.

超聲波清洗機(jī)漂洗是工件在除油、除銹、水洗、表調(diào)、磷化等工藝中滲透在焊接夾縫內(nèi)的液體很難排出,且水洗不能完全清除干凈,在濕熱條件下夾雜物極易造成工件泛黃、生銹。
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.
如果這些殘液在烘干過(guò)程中不能完全干固,隨后粉末噴涂以高溫烘干時(shí),殘液由于熱膨脹的作用將滲出焊縫,影響涂料與金屬表面的結(jié)合,造成涂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.
