According to the relevant expert research, you can use the hairy glass sheet method, aluminum foil test method and ultrasonic energy bottle test method to detect the cleaning effect of the workpiece.
Aluminum foil test method
When using the aluminum foil test method to detect the cleaning effect of ultrasonic cleaning machine, it was found that the 10μm aluminum foil paper was severely damaged during the test, and the cleaning effect could not be judged. Other thickness of aluminum foil test pass rate difference is relatively small. Through monitoring experiments found that more than 20μm thickness of aluminum foil paper as a testing tool, the cleaning effect is more obvious and more convenient to detect.
Frosted glass sheet detection method and ultrasonic energy bottle detection method
In the use of frosted glass sheet or ultrasonic energy bottle to detect the cleaning effect of ultrasonic cleaning machine, it was found that the size of the item being tested does not affect the detection effect, but the placement position will have a certain impact. To ensure the accuracy of the detection, it is necessary to design different test groups according to the cleaning time, cleaning temperature and cleaning frequency, and the number of trials per group to meet the relevant requirements.
When people use three methods at the same time to monitor the cleaning effect of ultrasonic cleaning machine, found that the aluminum foil test method and ultrasonic energy bottle test method of detection pass rate is significantly lower than the gross glass method, and monitoring results are more accurate. It can be seen that the aluminum foil test method and ultrasonic energy bottle test method is more suitable for monitoring the cleaning effect of ultrasonic cleaning machine. If the conditions do not allow, people will choose the hair glass method, the hair glass piece placed vertically in the four corners of the cleaning machine position to make the detection more accurate.
