產品噴涂前處置工藝非常重要，一般的保守工藝使用酸液對工件進行處理，對環境污染較重，工作環境較差，同時，弊端是結構復雜零件酸洗除銹后的殘酸很難沖洗干凈。工件噴涂后，時間不長，沿著夾縫呈現銹蝕現象，破壞涂層外表，嚴重影響產品外觀和內在質量。超聲波清洗技術應用到涂裝前處理后，不只能使物體外表和縫隙中的污垢迅速剝落，而且涂裝件噴涂層牢固不會返銹。

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.

超聲波清洗在各行各業都可用到以上的幾種僅是具有代表性的行業應用，還有許多新的行業和領域都可以使用超聲波清洗機，期待著廣大使用單位和生產廠家共同開發探索。

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.

超聲波測厚及應用

Ultrasonic thickness measurement and its application

工業領域中超聲波測厚是一門成熟的高新技術，優點是檢測平安、可靠及精度高，而且它可以巡回在運行狀態進行檢測。超聲測厚儀按工作原理分：有共振法、干涉法及脈沖反射法等。

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.

幾種，由于脈沖反射法并不涉及共振機理，與被測物表面的光潔度關系不密切，所以超聲波脈沖法測厚儀是受用戶歡迎的一種儀表。

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.
