How do titanium rods remove oil from the surface

There are many ways to remove oil from the surface of titanium rods, just like when the workpiece is too large, the local want to deal with plating or oil-free equipment, it can be used to remove oil by brushing. When using a brush to remove oil, it is possible to use a brush or cloth stained with lime slurry, magnesium oxide, cement, soap, tile ash, wood ash these metal detergents, the surface of the active agent or detergent powder and then scrub back and forth, so repeated several times in fact, you can completely remove the oil.

The drum oil removal of titanium rod processing is to put small parts with simple shapes, such as standard parts and wood chips, saponin and weak alkaline solution in the drum together, seal it, and roll oil removal at 60~100r/mhi speed. Ultrasonic cleaning is the use of high frequency sound waves above 16kHZ of the so-called ultrasonic wave (more than the human ear perceived frequency) for cleaning oil removal. When the ultrasonic wave is emitted into the liquid, the pressure reduction is generated at a certain moment, and the compression force is generated at the next moment, and so on. When the decompression effect is produced, a vacuum space will appear in the solution, and the solution steam (water vapor, degreaser steam) and the dissolved gas in the solution will enter the jet and form bubbles. At the moment after the bubble is produced, due to the action of compression force, the bubble is crushed, and the shock wave is generated, which can produce the effect of oil on the surface of the workpiece from the workpiece. When the bubble is destroyed, it can produce thousands of degrees of high temperature and hundreds of thousands of kilopascals of calendar force. Ultrasonic cleaning is the use of shock wave on the destruction of the oil film and cavitation phenomenon caused by the fierce stirring effect. The sound pressure generated by the reflection of the ultrasonic wave is also the cause of the agitation solution.

The ultrasonic generating device consists of an oscillator and a vibrator (called a vibrator). There are two types of vibrators: the throwing type and the external type. When using the drop type, the oscillator should be placed in the slot very effective parts. When the workpiece is small, a higher frequency is used, and when the workpiece is large, the frequency is low, generally about 30kHz.

Ultrasonic can be used for solvent degreasing, electric degreasing, chemical degreasing and pickling, which can greatly improve its efficiency. Its disadvantage is that it is transmitted in a straight line and it is difficult to reach the sheltered part, so the workpiece should be rotated or flipped in the slot. When the net basket is used for oil removal, the mesh is small, the shielding effect of Zhao sonic wave is large, and the intensity attenuation is severe. Large mesh, and easy to miss parts. At this time, it is appropriate to use the bottom irradiation method, that is, the use of 0.1 ~ 0.4cm non-porous board as the bottom plate, so that the ultrasonic wave passes through the bottom plate to reach the Q temperature on the workpiece is too high, too many bubbles are generated, but hinder the propagation of ultrasonic waves. For pure water, the best washing capacity is achieved at 501. For different components of the oil removal fluid, should be tested to find the best temperature.
