Ultrasonic cleaners are already very common in industrial applications, and they are ideal for cleaning and descaling workpieces. However, in order to play a better role, in the process of using ultrasonic descaling, you need to pay attention to the following three major matters.

1. Pay attention to the details of ultrasonic rust removal
When using ultrasonic cleaning equipment to remove oil and rust, pay attention to the corresponding proportion of phosphoric acid and other solutions for the corresponding deployment, through a series of functions can be within a few minutes to quickly clean up the oil stains. And insoluble phosphate film is formed on the surface. The manufacturer introduced that if it is not rinsed with water, the hydrochloric acid film also has corrosion resistance in the air. Because the hydrochloric acid film acts as a crystal nucleus during phosphating to improve the adhesion and corrosion resistance of the powder, it is often used.

Second, pay attention to ultrasonic rinsing
Ultrasonic rinsing utilizes the characteristics of "no holes" and "cavitation" of ultrasonic waves, so it can remove some very difficult dirt that used to be big, such as some dead corners or dirt in the slit, etc., so as to achieve subsequent processing Quality requirements. The manufacturer emphasizes that this method is a good solution to the residual liquid or dirt in the welding gap of related equipment. The ordinary method is difficult to write clearly, but as long as the rinsing process using ultrasonic cleaning can accomplish this requirement and purpose, it can be Very good to avoid the aging of the workpiece rust or yellowing.

Third, pay attention to adjust the ultrasonic cleaning process parameters
Studies have shown that ultrasonic cleaning has a direct relationship with the effect of rust removal and rinsing, but indirectly depends on the intensity of the ultrasound. Normally, the water-soluble medium can produce cavitation when the ultrasonic power per unit area reaches a certain level. Within a certain range, as long as you try to increase the ultrasonic intensity, the effect can be significantly improved, so the manufacturer reminds that cleaning is generally within a certain range of power density. At the same time, we must also pay attention to adjust the vibration frequency and temperature.

In short, ultrasonic cleaning technology used in pre-coating treatment can play a very good effect. The manufacturer emphasized that the addition of ultrasonic rinsing has solved many troublesome problems, thus greatly improving the phosphating quality of the workpiece, so it is also very helpful for the qual
