Ultrasonic cleaning of plastics
The effect of ultrasonic cleaning is related to the elastic modulus of the material. According to the difference of energy absorption intensity of high-frequency mechanical vibration, the extent of foreign matter stripping is different for different materials. The elastic modulus of plastic is much smaller than that of metal, and it also has strong absorption of ultrasonic wave.
Plastic is very different from stainless steel due to its soft texture and poor corrosion resistance. It can no longer be cleaned in corrosive liquid. In fact, we should understand that the absorption of high-frequency mechanical vibration energy by different materials is very different, and the plastic strength is far less than that of metal materials. So, in the face of ultrasonic cleaning, can we resist the effect of ultrasonic?
Actually, it is possible. After testing by professional engineers in the factory, ordinary plastics can indeed be cleaned by ultrasonic. The optimal cleaning temperature of the cleaning solution is about 50. Especially in cold weather, if the temperature of the cleaning solution we put in is low, the cavitation effect and cleaning effect will be very poor.
Therefore, when we use the full-automatic ultrasonic cleaning machine for cleaning, we should learn to control the ultrasonic cleaning temperature according to different materials. If it is not well controlled, it will cause irreversible damage to the workpiece.
Ultrasonic cleaning silica gel
Because silica gel is solidified by absorbing moisture in the air, the surface is easy to absorb and penetrate various organic substances. Organic substances inevitably deteriorate, blacken and moldy in a humid and dark environment. In addition, there may be dust and impurities on the surface of silica gel, which will affect the appearance and quality. Silica gel must be cleaned.
Use the ultrasonic cleaning machine to clean, and the ultrasonic cleaning machine can effectively clean the mildew, dust, impurities, etc. on the silica gel. The principle of ultrasonic cleaning is not difficult to understand. Ultrasonic is a physical cleaning method (cavitation).
The transducer is converted into high-frequency mechanical oscillation and propagated to the medium. The forward radiation of the ultrasonic wave in the cleaning solution can produce tens of thousands of tiny bubbles. However, it produces cavitation, which constantly forms small "explosions" on the surface of the cleaned object, causing the dirt on the surface and cracks of the object to peel off rapidly, so as to achieve the purpose of cleaning and purifying the surface of the object, Of course, choosing the appropriate cleaning agent can achieve excellent cleaning effect.
The full-automatic ultrasonic cleaning machine has good cleaning effect, fast cleaning speed and high efficiency. It can greatly reduce the labor intensity of cleaning staff, especially for large quantities of silica gel at this stage. The ultrasonic cleaning method is especially suitable for silica gel, which not only improves the work efficiency, but also fully guarantees and effects the cleanliness of silica gel, gives full play to the utilization rate of ultrasonic cleaning machine, and maximizes the benefits of the workshop.
