Titanium standard parts surface oil will affect its normal use, so it will be regularly cleaned, titanium standard parts in the processing of titanium surface will be processed more smooth, conducive to the cleaning of the later, the following is introduced to the surface of titanium standard parts de-oiling methods.
Titanium standard parts surface oil removal there are many ways, such as when the workpiece is too large, local surface treatment, you can use a simple scrub brush to remove oil, scrub brush to remove oil, brush or rag dipped in lime slurry, magnesium oxide, cement, soap solution, tile ash and other decontaminating powders back and forth scrubbing brush, but also can be used to special metal cleaning agent to remove the oil, and sometimes scrub brush once, dipped in degreasing agent and then rubbed, and so on for several times can be completely removed from the oil.
Roller degreasing is a simple shape of small parts, such as standard parts and wood shavings, soap pods and weak alkaline solution together into the drum, sealed with a lid, cleaning and degreasing. In the liquid to launch ultrasonic waves, the instantaneous generation of decompression, followed by the instantaneous generation of compressive force, so repeated action, the instant after the bubble is generated, due to the role of compressive force, the bubble is pressed, the bubble occurs to fly apart and produce shock waves, this shock wave can produce the role of the workpiece surface oil out of the workpiece, the bubble can produce thousands of degrees of height and hundreds of thousands of kilopascals of pressure when the destruction.
Ultrasonic can be used for solvent degreasing, electrolytic degreasing, chemical degreasing and pickling, can greatly improve its efficiency. Its disadvantage is that it propagates in a straight line and is difficult to reach the obscured part, therefore, it is desirable to rotate or turn the workpiece in the tank. In the use of mesh basket degreasing, mesh small, the masking effect on the ultrasonic waves, the intensity of the attenuation of great; mesh large, but also easy to miss the pieces. At this time, it is appropriate to use the bottom of the irradiation method, so that ultrasonic waves through the bottom plate and reach the workpiece on the Q When the temperature is too high, too many bubbles generated, but hinder the propagation of ultrasonic waves.
Suspended particles in the solution by the action of ultrasonic vibration, it will produce coagulation, on the one hand, is conducive to degreasing, but on the other hand, it is easy to make the pollutants again attached to the surface of the workpiece. Therefore, it is best to use continuous filtration equipment with oil-absorbing substances for solution filtration. High concentration of oil removal will affect the propagation of ultrasonic waves and reduce its effect. Therefore, the optimal concentration and ratio should be determined by test.
The above is the way of removing oil from titanium standard parts.
