1. Electrolytic cleaning is a cleaning method to remove the dirt on the metal surface by electrolysis. Electrolysis is a process of chemical decomposition of substances under the action of electric current. In the process of electrolysis, the dirt on the metal surface began to fall off, which accelerated the peeling under the impact of ultrasonic wave. The removal of sulfide, gas gas, broken resin, animal and vegetable oil, mineral oil, paraffin, carbon deposit and oxide layer on the metal surface by electrolytic method is called electrolytic degreasing.

2.当电流通过含有特殊配方的电解质的水溶液时，在电解槽的正极附近产生氧气，负极产生氢气。把要清洗的金属部件放入电解槽的正极，在电解过程中，在金属表面会有细小的氢气产生，这些小气泡促使污垢从金属表面剥离

2. When the current passes through the aqueous solution containing electrolyte with special formula, oxygen is generated near the positive electrode of the electrolytic cell and hydrogen is generated at the negative electrode. Put the metal parts to be cleaned into the positive pole of the electrolytic cell. In the electrolytic process, fine hydrogen will be generated on the metal surface. These small bubbles promote the dirt to peel off from the metal surface

3.超声波清洗是利用40KHZ的高频电源，使换能器由电能转换机械能的过程。在这过程中换能器向清洗槽溶液传递巨大的能量，在液体中产生正压和负压区，形成数以万计的空穴气泡，在不断的形成爆炸，冲击被清洗金属物表面，使金属表面的污垢快速脱离。

3. Ultrasonic cleaning is the process of converting the transducer from electrical energy to mechanical energy by using 40KHz high-frequency power supply. In this process, the transducer transmits huge energy to the solution of the cleaning tank, generates positive pressure and negative pressure areas in the liquid, forms tens of thousands of hole bubbles, and constantly forms an explosion, impacts the surface of the cleaned metal object, and quickly separates the dirt on the metal surface.

4.循环系统是由耐腐蚀的磁力泵、过滤器组成自循环，让清洗脱落的污垢迅速被过滤棉芯隔离，减少液面漂浮物。同时可加速溶液的电解，净化溶液的利用率。

4. The circulating system is composed of corrosion-resistant magnetic pump and filter, which can circulate automatically, so that the dirt falling off after cleaning can be quickly isolated by the filter cotton core and reduce the floating objects on the liquid surface. At the same time, it can accelerate the electrolysis of the solution and purify the utilization rate of the solution.

5.超声波清洗机应用在涂装处理的技术超声波清洗机器涂装前处置工艺非常重要，一般保守工艺是脱脂、水洗、盐酸除锈、水洗、中和、水洗、表调、水洗、磷化、水洗、烘干。此工艺大弊端是对结构复杂零件酸洗除锈后的残酸很难冲洗干净，尤其是焊接组合件磷化后，其夹缝内含有的残液影响后道工序的加工。

5. The application of ultrasonic cleaning machine in coating treatment technology. The treatment process of ultrasonic cleaning machine before coating is very important. The general conservative processes are degreasing, water washing, hydrochloric acid derusting, 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 wash the residual acid after pickling and derusting the parts with complex structure, especially after phosphating the welding assembly, the residual liquid contained in the gap affects the processing of the next process.

6.工件喷涂后，时间不长沿着夹缝呈现锈蚀现象，波坏涂层表面。严重影响产品外观和内在质量。如摩托车车轮、油箱、车架、防盗门等。经过近几年对超声波清洗机技术在磷化处理中的研究实践，提高产品喷涂质量，防止涂装件返锈方面，已取得良好效果。超声波清洗机漂洗工件在除油、除锈、水洗、表调、磷化等工艺中渗透在焊接夹缝内的液体很难排出，且水洗不能完全干净，湿热条件下夹杂物极易造成工件泛黄、生锈。

6. After the workpiece is sprayed for a short time, the corrosion phenomenon appears along the crevice, damaging the coating surface. Seriously affect the appearance and internal quality of products. Such as motorcycle wheel, fuel tank, frame, anti-theft door, etc. 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. In the processes of degreasing, derusting, water washing, surface conditioning, phosphating and so on, the liquid penetrating into the welding seam of the workpiece rinsed by the ultrasonic cleaning machine is difficult to discharge, and the water washing can not completely remove it. Under wet and hot conditions, the inclusions are very easy to cause yellowing and rust of the workpiece.

7.如果这些残液在烘干过程中不能完全干固，随后粉末喷涂以高温烘干时，残液由于热膨胀的作用将渗出焊缝，影响涂料与金属表面的结合，造成涂层的附着力下降甚脱离。.超声波清洗机工艺参数超声波清洗温度是影响清洗速度的重要因素，适当提高清洗温度可增加空化能力、缩短清洗时间，但超越一定温度，由于蒸气压力增加反而降低空化作用，因此必需坚持一定的温度。试验标明水溶性介质一般在50℃ 5效果佳。

7. If these residual liquids cannot be completely dry and solid in the drying process, and then when the powder is sprayed and dried at high temperature, the residual liquid will seep out of the weld due to the effect of thermal expansion, affecting the combination of the coating and the metal surface, resulting in the decrease or even separation of the adhesion of the coating Ultrasonic cleaning machine process parameters ultrasonic cleaning temperature is an important factor affecting the cleaning speed. Appropriately increasing the cleaning temperature can increase the cavitation capacity and shorten the cleaning time. However, if it exceeds a certain temperature, the cavitation will be reduced due to the increase of steam pressure. Therefore, it is necessary to adhere to a certain temperature. The test shows that the effect of water-soluble medium is the best at 50 ℃ 5.
