How can titanium rods remove surface oil?

Release time:2023-11-23 16:17:23

There are many methods for removing oil from the surface of titanium rods, such as using a brush to remove oil when the workpiece is too large and needs to be treated with coating or oil-free equipment locally. When using a brush to remove oil, you can use a brush or cloth dipped in metal detergents such as lime slurry, magnesium oxide, cement, soap solution, tile ash, and plant ash. The surface active agent or cleaning powder can be brushed back and forth to completely remove the oil.

The drum degreasing process for titanium rod processing involves placing small parts with simple shapes, such as standard parts, along with wood chips, soap pods, and weakly alkaline solutions, into the drum, sealing it with a lid, and performing rolling and degreasing at a speed of 60-100r/mhi. Ultrasonic cleaning is the use of high-frequency sound waves with a frequency of over 16kHz (beyond the frequency perceived by the human ear) for cleaning and oil removal. When ultrasonic waves are emitted into a liquid, a moment of pressure reduction is generated, followed by a moment of compressive force, and so on repeatedly. When reducing pressure occurs, a vacuum space will appear in the solution, and solution vapors (water vapor, degreaser vapor) and dissolved gases in the solution will enter the air to form bubbles. At the moment after the formation of bubbles, due to the effect of compression, the bubbles are crushed, causing them to scatter and generate shock waves. This shock wave can cause oil stains on the surface of the workpiece to detach from the workpiece. When bubbles break, they can generate high temperatures of thousands of degrees and a force of hundreds of thousands of kilopascals. Ultrasonic cleaning utilizes the destructive effect of shock waves on oil films and the intense stirring effect caused by cavity phenomena. The sound pressure generated by the reflection of ultrasound is also the reason for stirring the solution.

The ultrasonic generator device consists of an oscillator and a oscillator (referred to as a oscillator). There are two types of oscillators: throwing type and external attachment type. When using a human input method, the oscillator should be placed in an effective part of the slot. When the workpiece is small, a higher frequency is used, while when the workpiece is large, the frequency is lowered, usually around 30kHz.

Ultrasonic waves can be used for solvent oil removal, electrolytic oil removal, chemical oil removal, and acid washing, greatly improving their efficiency. Its disadvantage is that it propagates in a straight line, making it difficult to reach the obscured part. Therefore, the workpiece should rotate or flip inside the groove. When using a net basket for oil removal, the mesh size is small, which has a greater shielding effect on Zhao Soundwave and a significant strength attenuation; The mesh is large and prone to missing parts. At this time, it is advisable to use bottom irradiation method, which is to use a 0.1-0.4cm perforated thin plate as the bottom plate, so that ultrasonic waves can pass through the bottom plate and reach the workpiece. When the temperature is too high, too many bubbles are generated, which actually hinders the propagation of ultrasonic waves. For pure water, the optimal washing capacity is achieved at 501. For different compositions of degreasing liquids, experiments should be conducted to find the optimal temperature.
