Medical titanium rod There are many other degreasing methods on the surface. For example, when the workpiece is too large, local surface treatment (such as coating, etc.) or there is no degreasing equipment, a simple brush can also be used for degreasing. When wiping and degreasing, use a brush or rag to dip lime slurry, magnesium oxide, cement, soap solution, tile ash, plant ash, sodium carbonate and metal cleaner Wipe the surfactant and detergent back and forth to remove the oil. Sometimes, after wiping once, wipe it again with the degreasing fluid, so that the oil can be removed several times.

The drum degreasing for medical titanium rod processing is to place small parts with simple shape, such as standard parts, together with wood chips, soap pods and weak alkaline solutions into the drum, cover and seal them, and roll to degrease at a speed of 60~100r/mhi. Ultrasonic cleaning is to use the so-called ultrasonic wave (exceeding the frequency perceived by the human ear) with high frequency sound waves above 16kHz for cleaning and degreasing. When the ultrasonic wave is emitted into the liquid, the pressure will be reduced at a certain moment, and then the compression force will be generated at the next moment, and so on. When decompression occurs, there will be a vacuum space in the solution, and the solution vapor (water vapor, degreasing agent vapor) and dissolved gas in the solution will flow into the solution and form bubbles. At the moment after the bubble is generated, due to the compression force, the bubble is crushed, and the shock wave is generated due to the flying. This shock wave can cause the oil stain on the surface of the workpiece to separate from the workpiece. When bubbles are destroyed, they can produce thousands of degrees of high temperature and hundreds of thousands of kilopascals of pressure. Ultrasonic cleaning is to use the destruction of shock wave on oil film and the intense stirring effect of cavity phenomenon. The sound pressure generated by the reflection of ultrasonic wave is also the reason for stirring the solution.
