After a period of use, the metal without rust prevention treatment will produce oxidation due to the relationship between air and water. And the rust on the metal will affect its use effect and shorten its service life. Now the mainstream method of industrial derusting is to use industrial ultrasonic cleaning machine to remove rust. What is the principle of ultrasonic cleaning machine?
Rust removal principle of ultrasonic cleaning machine:
First of all, we have to know that rust spots and oxide scales are substances attached to the surface of the object. There is a gap between them and the surface of the object, and they can fall off. However, due to strong adhesion and hidden location, the effect of general derusting methods is limited. The derusting function of the ultrasonic cleaning machine is mainly to convert electric energy into mechanical kinetic energy through the transducer, radiate ultrasonic waves into the liquid in the tank through the cleaning tank. And then conduct high-frequency impact on the surface of the object through the cavitation generated by the liquid medium. This impact will basically not cause damage to the body. Under the continuous impact of high-frequency, Dirt (such as rust) on the surface of the object completely fell off with the help of cleaning agent. Under this impact, ultrasonic cleaning can not only remove rust, but also make the surface of the object look new.
Scope of application of ultrasonic cleaning machine for rust removal:
Industrial industry: degreasing and derusting of various parts, cleaning of measuring instruments, degreasing and derusting of auto parts and engines, removal of antirust grease, degreasing, derusting and rust prevention of various parts of locomotive, etc.
Surface treatment: surface activation treatment of metal materials, removal of polishing paste, rust and oil removal before electroplating, etc.
Other industries: photosensitive material manufacturing, papermaking, liquid defoaming in some food fields (removing dissolved air).
Usage of ultrasonic cleaning machine for rust removal:
1. Plug in the power supply, check whether the display is normal, confirm that the machine is powered on, the power indicator light is on, and the display screen of the display panel is on;
2. Add cleaning fluid into the inner tank of the machine, and put the cleaning blue containing items into the inner tank of the machine;
3. Set the cleaning time and press start;
4. If heating is used, press the temperature switch to turn on the heating after setting the temperature;
5. After cleaning, turn off the power and unplug the power cord of the machine, dispose of the cleaning fluid in the tank of the machine, wipe it clean, and put it away.
Precautions for the use of ultrasonic cleaning machine for rust removal:
Before connecting the power supply, please make sure whether the voltage is within the rated range. Do not modify the product!
Before use, ensure that the ground wire is reliably connected to prevent static electricity.
It is recommended to suspend the machine for a period of time (usually more than 3 minutes) after working for one hour before starting the machine.
Please do not use in the environment with too high or too low temperature.
Please do not use in the environment with strong vibration or impact.
Please do not use in the presence of corrosive gas or dust.
Please do not use it in the environment with water, oil and chemicals splashing.
Please do not use this machine in an environment with flammable and explosive gases.
It is forbidden to start the machine when there is no cleaning fluid in the cleaning tank.
Start the heating function, and the liquid in the cleaning tank shall not be less than 2/3 of the height of the tank in the cleaning tank; Without turning on the heating function, the liquid in the cleaning tank shall not be less than 1/2 of the high-precision section in the cleaning plant.
When using flammable and volatile liquids (such as alcohol, board washing water, etc.) for cleaning. It is strictly prohibited to heat up!
Ultrasonic cleaning machine and cleaning agent are used together, and the cleaning effect is better!
