产品喷涂前处置工艺非常重要，一般的保守工艺使用酸液对工件进行处理，对环境污染较重，工作环境较差，同时，弊端是结构复杂零件酸洗除锈后的残酸很难冲洗干净。工件喷涂后，时间不长，沿着夹缝呈现锈蚀现象，破坏涂层外表，严重影响产品外观和内在质量。超声波清洗技术应用到涂装前处理后，不只能使物体外表和缝隙中的污垢迅速剥落，而且涂装件喷涂层牢固不会返锈。

The treatment process before spraying is very important. The general conservative process uses acid solution to treat the workpiece, which causes serious environmental pollution and poor working environment. At the same time, the disadvantage is that the residual acid after pickling and derusting of parts with complex structure is difficult to clean. After spraying for a short time, the workpiece will rust along the cracks, which will damage the surface of the coating and seriously affect the appearance and internal quality of the product. After the ultrasonic cleaning technology is applied to the pretreatment of coating, not only can the dirt on the surface and crevice of the object be peeled off rapidly, but also the spraying layer of the coated parts is firm and will not return to rust.

超声波清洗在各行各业都可用到以上的几种仅是具有代表性的行业应用，还有许多新的行业和领域都可以使用超声波清洗机，期待着广大使用单位和生产厂家共同开发探索。

Ultrasonic cleaning can be used in all walks of life. The above several are only representative industry applications. There are many new industries and fields that can use ultrasonic cleaning machine. We are looking forward to the joint development and exploration of the majority of users and manufacturers.

超声波测厚及应用

Ultrasonic thickness measurement and its application

工业领域中超声波测厚是一门成熟的高新技术，优点是检测平安、可靠及精度高，而且它可以巡回在运行状态进行检测。超声测厚仪按工作原理分：有共振法、干涉法及脉冲反射法等。

Ultrasonic thickness measurement is a mature high-tech in the industrial field. It has the advantages of safe, reliable and high-precision detection, and it can be carried out in the running state. According to the working principle, ultrasonic thickness gauge can be divided into resonance method, interference method and pulse reflection method.

几种，由于脉冲反射法并不涉及共振机理，与被测物表面的光洁度关系不密切，所以超声波脉冲法测厚仪是受用户欢迎的一种仪表。

Because the pulse reflection method does not involve resonance mechanism and is not closely related to the surface finish of the object to be measured, the ultrasonic pulse thickness gauge is a popular instrument for users.
