超声波清洗器利用超声波发生器所发出的交频讯号，通过换能器转换成了交频机械振荡而传播到介质——清洗液中，超声波在清洗液中以疏密相间的形式向被洗物件辐射。产生“空化”现象，即在清洗液中“气泡”形式，产生破裂现象。当“空化”在达到被洗物体表面破裂的 ，产生优于过1000个大气压力的冲击力，致使物体的面、孔、隙中的污垢被分散、破裂及剥落，使物体达到净化清洁。

The ultrasonic cleaner uses the cross frequency signal emitted by the ultrasonic generator, which is converted into cross frequency mechanical oscillation by the transducer and propagated to the medium - cleaning solution. The ultrasonic waves radiate to the object to be washed in a sparse and dense manner in the cleaning solution. The phenomenon of "cavitation" occurs, which refers to the rupture of bubbles in the cleaning solution. When cavitation reaches the surface of the object being washed and ruptures, it generates an impact force far exceeding 1000 atmospheric pressures, causing the dirt in the surface, holes, and gaps of the object to be dispersed, ruptured, and peeled off, achieving purification and cleanliness of the object.

激光清洗技术是指利用高能激光束照射工件表面，使表面的污物、锈斑或涂层发生 蒸发或剥离，高速 地 清洁对象表面附着物或表面涂层，从而达到洁净的工艺过程。它是基于激光与物质相互作用效应的一项新技术，与传统的机械清洗法、化学腐蚀清洗、液体固体冲击清洗、高频超声清洗等传统清洗方法相比，有明显的优点。它快捷、成本低，对基片产生的热负荷和机械负荷小，清洗为非 ;废物可回收，无环境污染物 可靠，不损害操作人员健康证可以 各种不同厚度、不同成份的涂层次清洁过程易于实现自动化控制，实现远距离遥控清洗等。

Laser cleaning technology refers to the process of using high-energy laser beams to irradiate the surface of a workpiece, causing the evaporation or peeling of dirt, rust, or coatings on the surface, and rapidly cleaning the surface attachments or coatings of the object, thereby achieving a clean process. It is a new technology based on the interaction effect between laser and matter, which has significant advantages compared to traditional cleaning methods such as mechanical cleaning, chemical corrosion cleaning, liquid solid impact cleaning, and high-frequency ultrasonic cleaning. It is fast, low-cost, and has low thermal and mechanical loads on the substrate, making cleaning non essential; Waste can be recycled, there are no environmental pollutants, it is reliable, and it does not damage the health certificate of operators. The cleaning process can be easily automated with different thicknesses and compositions of coating layers, and remote control cleaning can be achieved.

激光清洗和超声波清洗的区别在于激光清洗操作很方便，一般手持清洗即可，不需要明显介质直接可以对物体表面进行清洗，对于大面积清洗和精密零部件清洗效果都很好，工作温度在-5℃~50℃皆可而超声波需要添加清洗剂，超声波的功率密度越高，空化效果越强，速度越快，清洗效果越好，但对于精密的表面光洁度甚高的物件，采用长时间的高功率密度清洗会对物件表面产生空化、腐蚀，采用50°C~70°C的工作温度。

The difference between laser cleaning and ultrasonic cleaning is that laser cleaning is very convenient to operate. Generally, handheld cleaning is sufficient, and no medium is needed to directly clean the surface of the object. It has good cleaning effects for large-area cleaning and precision component cleaning. The working temperature can be between -5 ℃~50 ℃, while ultrasonic cleaning requires the addition of cleaning agents. The higher the power density of ultrasonic cleaning, the stronger the cavitation effect, the faster the speed, and the better the cleaning effect. However, for precision objects with high surface smoothness, long-term high-power density cleaning will cause cavitation and corrosion on the surface of the object. Using a working temperature of 50 ° C~70 ° C is recommended.

激光清洗有可以与被清洗物不接触的优势。超声波清洗的方法是近距离清洗，对清洗物体表面 械作用力，容易 物体表面。而激光清洗是一种非接触加工，可方便地实现远距离操作。

Laser cleaning has the advantage of not coming into contact with the object being cleaned. The method of ultrasonic cleaning is close range cleaning, which applies mechanical force to the surface of the cleaned object, making it easier to clean the surface of the object. Laser cleaning is a non-contact process that can be easily operated remotely.
