China's industry has developed greatly, and the metal processing of aluminum alloy is a leap. However, in the manufacturing process of aluminum alloy workpiece, aluminum chips and other dirt will inevitably be left on the surface of the workpiece. If the surface of aluminum alloy is not cleaned, the processing work in the future will be very difficult. Therefore, the cleaning of aluminum alloy workpiece has become an urgent problem to be solved. At present, ultrasonic cleaning machine is widely used in industrial field. Ultrasonic cleaning of workpieces is loved by many industries because of its convenience and high efficiency. In this way, the aluminum alloy workpiece can be cleaned by ultrasonic cleaning machine.

铝被广泛应用于航空、汽车、电子等机械制造行业，但铝件的清洗比较困难。这时，需要用超声波清洗机来清洗铝件。超声清洗技术的工作原理是超声换能器产生的高频振荡通过高频机械振荡传递到介质清洗液中，当声压达到一定值时，微小气泡迅速爆炸，然后突然闭合。微小气泡闭合时产生的冲击波冲击表面污渍，破坏不溶性污垢，使其分散在清洗液中，从而达到清洗工件表面的目的

Aluminum is widely used in aviation, automobile, electronics and other machinery manufacturing industries, but it is difficult to clean aluminum parts. At this time, the aluminum parts need to be cleaned by ultrasonic cleaning machine. The working principle of ultrasonic cleaning technology is that the high-frequency oscillation generated by ultrasonic transducer is transmitted to the medium cleaning solution through high-frequency mechanical oscillation. When the sound pressure reaches a certain value, the small bubbles explode rapidly and then close suddenly. The shock wave generated when the tiny bubble is closed impacts the surface stain, destroys the insoluble dirt and disperses it in the cleaning solution, so as to achieve the purpose of cleaning the workpiece surface

其中超声波具有穿透力强、效率高、清洗率高等特点，对表面复杂、小孔、盲孔、形状特殊的铝合金工件的超声波清洗更为有效。超声波清洗机能去除污垢而不损伤铝，清洗后的铝合金工件更加光滑光亮，是其他清洗方法无法比拟的，因此在行业中占有重要地位，也是一种非常实用的铝合金工件清洗方法。根据以上说明，铝合金工件可以用超声波清洗机清洗。

Among them, ultrasonic has the characteristics of strong penetration, high efficiency and high cleaning rate. It is more effective for ultrasonic cleaning of aluminum alloy workpieces with complex surface, small holes, blind holes and special shapes. Ultrasonic cleaning can remove dirt without damaging aluminum. The cleaned aluminum alloy workpiece is smoother and brighter than other cleaning methods. Therefore, it plays an important role in the industry and is also a very practical cleaning method for aluminum alloy workpiece. According to the above instructions, aluminum alloy workpieces can be cleaned by ultrasonic cleaning machine.

水基清洗剂是以表面活性剂为主要活性组分，与其它添加剂组成的混合体系。表面活性剂对清洗过程有很大影响，如：① 表面活性剂能破坏金属表面与污垢的相互作用键；② 可润湿的金属表面，使清洗液能包裹污垢颗粒；③ 它能将动植物油乳化成小液滴并分散在溶液中；④ 可溶性固体污垢颗粒；⑤ 能分散各种污垢，防止再沉积。表面活性剂作为清洗剂可以破坏污垢颗粒与金属表面的相互作用，但这些表面活性剂的润湿、渗透、乳化、分散和剥离能力并不理想。因此，在水基清洗剂的配方中经常使用几种不同的表面活性剂

Water based cleaning agent is a mixed system with surfactant as the main active component and other additives. Surfactants have a great influence on the cleaning process, such as: ① surfactants can destroy the interaction bond between metal surface and dirt; ② The dirt liquid can wet the surface of metal particles; ③ It can emulsify animal and vegetable oil into small droplets and disperse them in solution; ④ Soluble solid dirt particles; ⑤ It can disperse all kinds of dirt and prevent re deposition. Surfactants as cleaning agents can destroy the interaction between dirt particles and metal surface, but the wettability, penetration, emulsification, dispersion and stripping ability of these surfactants are not ideal. Therefore, several different surfactants are often used in the formulation of water-based cleaning agents
