With the widespread use of ultrasonic cleaning machines, for example, some workpieces that use ultrasonic cleaning machines to remove oil may not have a significant rust removal effect. How do we detect whether ultrasonic cleaning has cleaned the oil thoroughly? Today we will talk about the methods for testing the effectiveness of oil removal and cleaning after using an ultrasonic cleaning machine to remove oil.


Testing the surface oil removal effect of ultrasonic cleaning machines is actually a test of the degree of surface hydrophilicity. In addition to specialized instruments for scientific experiments and mechanism research, there are several commonly used methods for testing the surface oil removal effect:



1. Surface hydrophilicity observation


It is to immerse the degreased parts in clean water and take them out, observing the water's residence on the surface of the degreased parts. A completely hydrophilic surface will have a uniform water film, and even after excess water flows, the surface remains completely moist. If there are local areas where oil removal is not good, water splashes or oil spots will appear, that is, the water film will have some non moist areas that are basically circular; If the oil removal is not good in most parts, the surface of the parts is basically not hydrophilic, and the water on the surface will quickly drip off after being taken out of clean water without getting wet.


2. Wipe with a white tissue


Firstly, use a clean white tissue to wipe the degreased surface, and then check if there are any oil stains left on the surface of the tissue. If the degreased surface is clean, there are only water stains on the tissue; On surfaces that are not cleaned by degreasing, there will be oil stains on tissues. The extremely thin oil film is transparent and cannot be seen with the naked eye, but after wiping with a tissue, oil stains are collected on the tissue and easily appear.


3. Test with a Dyne pen


We usually use this method to test whether the cleaning oil stains are dry or not, because it is relatively simple and convenient. First, prepare a dyne pen, and then draw a line on the surface of the degreased workpiece. If the degreasing is clean, the ink on the surface of the workpiece will not shrink or scatter, making cleaning visible; If the oil removal is not clean, the lines on the surface of the workpiece will shrink, become blurry, and the color will become lighter.
