How does a titanium rod remove oil from the surface

There are many methods of titanium rod surface oil removal, just like when the workpiece is too large, local want to deal with coating or oil free equipment, can be used to brush oil removal. In the use of brush oil removal, it is possible to use a brush or cloth stained with lime slurry, magnesium oxide, cement, soap liquid, tile ash, plant ash these metal detergent, surfactant on the surface or detergent back and forth, so repeated several times in fact, you can get rid of the oil thoroughly.

The drum oil removal of titanium rod processing is to put simple small parts, such as standard parts, wood chips, shitonapple and weak alkaline solution together in the drum, capped and sealed, with 60~100r/mhi speed for rolling oil removal. Ultrasonic cleaning is the use of more than 16kHZ high frequency sound waves of the so-called ultrasonic (more than the frequency of human ear perception) to clean and remove oil. When an ultrasonic wave is fired into a liquid, the pressure is reduced for an instant, followed by a compression force for an instant, and so on and so forth. In the production of decompression, there will be a vacuum space in the solution, solution steam (water vapor, oil removal agent steam) and dissolved in the solution of gas into the human flies in the formation of bubbles. The moment after the bubble is produced, due to the effect of compression force, the bubble is crushed, flying and producing shock wave, which can produce the effect of oil pollution from the workpiece surface. Bubbles can destroy with thousands of degrees of heat and hundreds of thousands of kilopascals. Ultrasonic cleaning is the use of shock wave on the oil film destruction and cavitation phenomenon produced by the intense stirring. The sound pressure caused by the reflection of ultrasonic wave is also the cause of stirring solution.

The ultrasonic generator is composed of an oscillator and a vibrator (vibrator). There are two kinds of vibrators: throwing type and external attached type. When using the throwing type, the oscillator should be placed in the slot in a very effective part. When the workpiece is small, the frequency is higher, and when the workpiece is large, the frequency is lower, usually about 30kHz.

Ultrasonic wave can be used for solvent oil removal, electric oil removal, chemical oil removal and pickling, which can greatly improve its efficiency. Its disadvantage is linear propagation, it is difficult to reach the shaded part, therefore, the workpiece should be rotated or turned in the slot. When the net basket is used for oil removal, the mesh is small, the shielding effect of the zhao sound wave is large, and the intensity attenuation is strong; Large mesh, and easy to miss pieces. At this time, it is appropriate to use the bottom irradiation method, that is, the use of 0.1 ~ 0.4cm non-porous plate as the bottom plate, so that the ultrasonic wave through the bottom plate and reach the workpiece Q temperature is too high, too many bubbles, but hinder the transmission of ultrasonic wave. For pure water, 501 hours to achieve the best washing capacity. For different composition of oil removal fluid, should be tested to find the best temperature.
