超聲波清洗機(jī)涂裝前的處理工藝非常重要,一般保守的工藝有脫脂、水洗、鹽酸除銹、水洗、中和、水洗、表面調(diào)理、水洗、磷化、水洗、烘干。這種工藝的缺點(diǎn)是結(jié)構(gòu)復(fù)雜的零件酸洗除銹后殘酸難以清除,特別是焊接總成磷化后,縫隙中的殘液影響下道工序的加工。噴涂后,工件會(huì)在短時(shí)間內(nèi)沿著裂紋生銹,涂層表面會(huì)受到損傷。嚴(yán)重影響產(chǎn)品的外觀(guān)和內(nèi)在質(zhì)量。如摩托車(chē)車(chē)輪、油箱、車(chē)架、防盜門(mén)等
The treatment process before coating of ultrasonic cleaning machine is very important. Generally conservative processes include degreasing, water washing, hydrochloric acid derusting, water washing, neutralization, water washing, surface conditioning, water washing, phosphating, water washing and drying. The disadvantage of this process is that it is difficult to remove the residual acid after pickling and derusting of parts with complex structure, especially after phosphating of welding assembly, the residual liquid in the gap affects the processing of the next process. After spraying, the workpiece will rust along the crack in a short time, and the coating surface will be damaged. Seriously affect the appearance and internal quality of products. Such as motorcycle wheel, fuel tank, frame, anti-theft door, etc
通過(guò)近年來(lái)超聲波清洗機(jī)技術(shù)在磷化處理中的研究與實(shí)踐,在提高產(chǎn)品噴涂質(zhì)量、防止涂裝件生銹方面取得了良好效果
Through the research and practice of ultrasonic cleaner technology in phosphating treatment in recent years, good results have been achieved in improving product spraying quality and preventing coating parts from rusting
工件在脫脂、除銹、水洗、表面調(diào)整、磷化等工序中,滲入焊縫的液體難以排出,而且水洗不能完全去除夾雜物,在濕熱條件下容易造成工件發(fā)黃生銹。如果在干燥過(guò)程中殘液不能完全干燥,那么在高溫下噴涂和干燥粉末時(shí),由于熱膨脹的影響,殘液會(huì)從焊縫中滲出,影響涂層與金屬表面的結(jié)合,導(dǎo)致涂層附著力降低甚至脫落。
During degreasing, derusting, water washing, surface adjustment, phosphating and other processes of the workpiece, the liquid penetrating into the weld is difficult to discharge, and the water washing can not completely remove the inclusions, which is easy to cause the workpiece to turn yellow and rust under hot and humid conditions. If the residual liquid cannot be completely dried during the drying process, when spraying and drying powder at high temperature, the residual liquid will seep out from the weld due to the influence of thermal expansion, affecting the combination between the coating and the metal surface, resulting in reduced adhesion or even falling off of the coating.
超聲波清洗機(jī)的工藝參數(shù)
Process parameters of ultrasonic cleaning machine
超聲波清洗溫度是影響清洗速度的重要因素。適當(dāng)提高清洗溫度可以提高汽蝕能力,縮短清洗時(shí)間,但超過(guò)一定溫度后,汽蝕效應(yīng)會(huì)因蒸汽壓力的升高而減小,因此一定保持一定的溫度。試驗(yàn)表明,水溶性介質(zhì)一般為50℃±5是好的。
Ultrasonic cleaning temperature is an important factor affecting the cleaning speed. Properly increasing the cleaning temperature can improve the cavitation capacity and shorten the cleaning time, but after exceeding a certain temperature, the cavitation effect will be reduced due to the increase of steam pressure, so a certain temperature must be maintained. The test shows that the water-soluble medium is generally 50 ℃ ± 5.
