电镀中，预处置惩罚的用意为了往除工件外貌存有污物及杂质，使之成为适宜电镀的活性外貌。电镀品质不良原由较多是预处置惩罚欠好。而预处置惩罚欠好，大多未应用超音波清洗设备。
In electroplating, the purpose of pre-treatment is to remove dirt and impurities from the surface of the workpiece, making it an active surface suitable for electroplating. There are many reasons for poor electroplating quality, which are due to poor pre-treatment. However, the preprocessing is not good enough, and most of them have not applied ultrasonic cleaning equipment.
电镀前处置惩罚时会须要依据工件的具体情况，选用适合的要领进行合理清洗。金属基材一般分为冲压件和压铸件。冲压件上边的油渍为一般冲压油，因其密度很是高所以比力随便清洗。一般可用酸洗、电解等。而锌、铝、铜等压铸件属较难清洗的因压铸件中添加了种种元素，此外在成形、拉涨、压延、切削、抛光的历程中另有须要运用种种油品，如机油、抛光油等。
During the pre-treatment of electroplating, it is necessary to select suitable methods for reasonable cleaning based on the specific situation of the workpiece. Metal substrates are generally divided into stamped parts and die castings. The oil stains on the top of the stamped parts are ordinary stamping oil, which is relatively easy to clean due to its high density. Generally, acid washing, electrolysis, etc. can be used. Zinc, aluminum, copper and other die castings are difficult to clean due to the addition of various elements in the die castings. In addition, it is necessary to use various oil products such as engine oil and polishing oil in the processes of forming, stretching, rolling, cutting, and polishing.
有关超声波清洗机而言，机油能够轻松往除。但抛光油分成黄油白油、绿油等，这比力难以往除。因此，有须要选择适合的超声清洗设备及清洗液。
Regarding ultrasonic cleaning machines, oil can be easily removed. But the polishing oil is divided into butter, white oil, green oil, etc., which is difficult to remove. Therefore, it is necessary to choose suitable ultrasonic cleaning equipment and cleaning solution.
超声频率一般为20-100KHZ之间。一般工件的预处置惩罚，一般接纳低频、中功率的超声清洗设备，如频率25-28KHZ，功率1W/cm。由于低频比高频在介质中随便发生空蚀，有关外形浅易、并不十分细致的工件，超声波清洗性能切合要求。特征是噪声较大价钱自制。对一些细致度较高的工件，现使用的一般均为高频40-68KHZ大功率的超声清洗机。因此类清洗机关于间隙、间隙、深孔、埋孔等外貌形繁杂的工件清洗效果较好。可是超声清洗的效果只是有溶液到达的地刚刚气起到清洗效果。也是说要制止深孔、埋孔含有气体，而且要留意杂质下落、油渍上漂和处置惩罚清洗不到位的状况。
The ultrasound frequency is generally between 20-100KHZ. The pre-treatment of general workpieces generally uses low-frequency and medium power ultrasonic cleaning equipment, such as 25-28KHZ frequency and 1W/cm power. Due to the random occurrence of cavitation in the medium at low frequencies compared to high frequencies, ultrasonic cleaning can meet the requirements for workpieces with simple and not very detailed shapes. The characteristic is high noise and low price. For some workpieces with high precision, the commonly used ones are high-frequency 40-68KHZ high-power ultrasonic cleaning machines. Therefore, this type of cleaning machine has a better cleaning effect on workpieces with complex surface shapes such as gaps, gaps, deep holes, and buried holes. But the effect of ultrasonic cleaning can only be achieved where the solution reaches. It also means to avoid deep holes and buried holes containing gas, and to pay attention to the situation of impurities falling, oil stains floating, and inadequate treatment and cleaning.
