The paint on the surface of titanium screws is the biggest problem, which will affect normal use. Therefore, regular cleaning will be carried out. When titanium nuts are processed, the titanium surface will be more smooth, which is conducive to later cleaning. Next, we will introduce the methods for removing oil from the surface of titanium standard parts.
There are many methods to remove the oil stain on the surface of titanium alloy gasket. For example, when the workpiece is too large and the local surface is treated, a simple brush can be used to remove the oil. When removing the oil, use a brush or rag to dip lime slurry, magnesium oxide, soap solution, tile plaster and other detergent to brush back and forth, or use a special metal cleaner to remove the oil. Sometimes, after brushing once, rub again with the degreaser, so that the oil can be completely removed several times.
Drum degreasing is to put small parts with simple shape, such as standard parts, together with wood chips, soap pods and weak alkaline solution into the drum, cover and seal them for cleaning and degreasing. When the ultrasonic wave is emitted into the liquid, the pressure is reduced instantaneously, and then the compression force is generated instantaneously. This repeated action will cause the bubble to be crushed due to the compression force at the moment after the bubble is generated, and the shock wave will be generated due to the scattering. This shock wave can cause the oil stain on the surface of the workpiece to leave the workpiece. When the bubble is damaged, thousands of degrees of height and hundreds of thousands of kilopascals of pressure can be generated.
Ultrasonic can be used for solvent degreasing, electrolytic degreasing, chemical degreasing and pickling, which can greatly improve its efficiency. Its disadvantage is that it travels in a straight line and is difficult to reach the shielded part, so the workpiece should rotate or turn over in the groove. When the basket is used for oil removal, the mesh is small, and the shielding effect on ultrasonic wave is large and the intensity is attenuated severely; Large mesh, easy to leak parts. At this time, it is better to use the bottom irradiation method to let the ultrasonic wave pass through the bottom plate and reach the workpiece. When thousands of temperatures are too high, too many bubbles will be generated, which will hinder the transmission of ultrasonic wave.
The suspended particles in the solution vibrate under the action of ultrasonic wave, which will produce agglutination. On the one hand, it is conducive to degreasing, but on the other hand, it is easy for pollutants to attach to the workpiece surface again. Therefore, it is better to use continuous filtration equipment with oil absorbing substances for solution filtration. High degreasing concentration will affect the transmission of ultrasonic wave and reduce its effect. Therefore, the best concentration and ratio shall be determined through experiments.
The above is the way to degrease titanium standard parts, and titanium can only be used normally if you know the cleaning method.
