1.電解清洗是利用電解作用將金屬表面的污垢去除的清洗方法。電解是在電流作用下物質(zhì)發(fā)生化學(xué)分解的過程。在電解過程中，金屬表面的污垢開始脫落，在超聲波的沖擊下加速了剝離。在在金屬表面沾有的硫化物、瓦斯氣、樹脂碎末、動植物油、礦物油、石蠟、積炭、氧化層，用電解的方法把這些污垢去除叫電解脫脂。1. electrolytic cleaning is a cleaning method that uses electrolysis to remove the dirt on the metal surface. electrolysis is the process of chemical decomposition of substances under the action of electric current. in the electrolysis process, the dirt on the metal surface began to fall off, which accelerated the peeling under the impact of ultrasonic. removal of sulfide, gas, resin chips, animal and vegetable oils, mineral oils, paraffins, carbon deposits and oxide layers on metal surfaces by electrolysis is called electrolytic degreasing.
2.當(dāng)電流通過含有特殊配方的電解質(zhì)的水溶液時(shí)，在電解槽的正極附近產(chǎn)生氧氣，負(fù)極產(chǎn)生氫氣。把要清洗的金屬部件放入電解槽的正極，在電解過程中，在金屬表面會有細(xì)小的氫氣產(chǎn)生，這些小氣泡促使污垢從金屬表面剝離
2. when the current passes through the aqueous solution containing electrolyte with special formula, oxygen is generated near the positive pole of the electrolytic cell and hydrogen is generated at the negative pole. put the metal parts to be cleaned into the positive pole of the electrolytic cell. during electrolysis, small hydrogen will be generated on the metal surface, and these small bubbles will promote the dirt to peel off from the metal surface
3.超聲波清洗是利用40khz的高頻電源，使換能器由電能轉(zhuǎn)換機(jī)械能的過程。在這過程中換能器向清洗槽溶液傳遞巨大的能量，在液體中產(chǎn)生正壓和負(fù)壓區(qū)，形成數(shù)以萬計(jì)的空穴氣泡，在不斷的形成爆炸，沖擊被清洗金屬物表面，使金屬表面的污垢快速脫離。
3. ultrasonic cleaning is a process that uses 40khz high-frequency power supply to convert the transducer from electrical energy to mechanical energy. in this process, the transducer transfers huge energy to the cleaning tank solution, generating positive and negative pressure areas in the liquid, forming tens of thousands of hole bubbles, and constantly forming explosions, impacting the surface of the metal to be cleaned, so that the dirt on the metal surface can be quickly separated.
4.循環(huán)系統(tǒng)是由耐腐蝕的磁力泵、過濾器組成自循環(huán)，讓清洗脫落的污垢迅速被過濾棉芯隔離，減少液面漂浮物。同時(shí)可加速溶液的電解，凈化溶液的利用率。
4. the circulating system is a self circulating system composed of corrosion-resistant magnetic pump and filter, so that the dirt falling from cleaning can be quickly isolated by the filter cotton core to reduce the floating objects on the liquid surface. at the same time, it can accelerate the electrolysis of solution and purify the utilization rate of solution.
5.超聲波清洗機(jī)應(yīng)用在涂裝處理的技術(shù)超聲波清洗機(jī)器涂裝前處置工藝非常重要，一般保守工藝是脫脂、水洗、鹽酸除銹、水洗、中和、水洗、表調(diào)、水洗、磷化、水洗、烘干。此工藝弊端是對結(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。
5. the technology of ultrasonic cleaning machine applied in coating treatment the disposal process of ultrasonic cleaning machine before coating is very important. generally, the conservative processes are degreasing, water washing, hydrochloric acid rust removal, water washing, neutralization, water washing, surface conditioning, water washing, phosphating, water washing and drying. the biggest disadvantage of this process is that it is difficult to clean the residual acid after pickling and derusting for parts with complex structure, especially after the welding assembly is phosphatized, the residual liquid contained in the seam affects the processing of the next process.
6.工件噴涂后，時(shí)間不長沿著夾縫呈現(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。經(jīng)過近幾年對超聲波清洗機(jī)技術(shù)在磷化處理中的研究實(shí)踐，提高產(chǎn)品噴涂質(zhì)量，防止涂裝件返銹方面，已取得良好效果。超聲波清洗機(jī)漂洗工件在除油、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，且水洗不能清除干凈，濕熱條件下夾雜物極易造成工件泛黃、生銹。
6. after the workpiece is sprayed, it will rust along the seam for a short time, and the coating surface will be damaged. it seriously affects the appearance and internal quality of the product. such as motorcycle wheel, fuel tank, frame, anti-theft door, etc. in recent years, through the research and practice of ultrasonic cleaning machine technology in phosphating treatment, good results have been achieved in improving product spraying quality and preventing coating parts from rusting. it is difficult to discharge the liquid that permeates in the welding seam during the processes of degreasing, rust removal, water washing, surface conditioning, phosphating, etc. of the workpiece rinsed by the ultrasonic cleaning machine, and the water washing can not completely remove it, and the inclusions are very easy to cause yellowing and rusting of the workpiece under hot and humid conditions.
7.如果這些殘液在烘干過程中不能干固，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。.超聲波清洗機(jī)工藝參數(shù)超聲波清洗溫度是影響清洗速度的重要因素，適當(dāng)提高清洗溫度可增加空化能力、縮短清洗時(shí)間，但超越一定溫度，由于蒸氣壓力增加反而降低空化作用，因此必需堅(jiān)持一定的溫度。試驗(yàn)標(biāo)明水溶性介質(zhì)一般在50℃ 5。
7. if these residues cannot be completely dried in the drying process, then when the powder is sprayed and dried at high temperature, the residues will seep out of the weld due to thermal expansion, affecting the combination of the paint and the metal surface, causing the adhesion of the coating to decline or even detach process parameters of ultrasonic cleaning machine ultrasonic cleaning temperature is an important factor affecting the cleaning speed. properly increasing the cleaning temperature can increase the cavitation capacity and shorten the cleaning time, but exceeding a certain temperature will reduce the cavitation effect due to the increase of steam pressure. therefore, a certain temperature must be maintained. the test shows that the water soluble medium is generally the best at 50 ℃ 5.
