Magnetic material ultrasonic cleaning machine is a device specially used for cleaning magnetic materials (such as permanent magnets, soft magnetic materials, magnetic powder cores, etc.). Combined with ultrasonic cleaning technology and magnetic material characteristics design, it can efficiently remove surface oil stains, particles, oxide layers and other pollutants. The following is a detailed introduction to the device:

1. Operating principle

Ultrasonic cavitation effect: High-frequency ultrasound (usually 20-40kHz) produces tiny bubbles in the cleaning solution. When the bubbles burst, they release an impact force and peel off the pollutants on the surface of the material.

Adaptability of magnetic materials: According to the characteristics of magnetic materials (such as brittleness, fear of corrosion, etc.), adjust the ultrasonic power, frequency and cleaning solution composition to avoid damaging the material performance.

2. Equipment composition

Ultrasonic generator: provides high-frequency electrical signals and drives the transducer.

Transductor: Convert electrical energy into mechanical vibration to produce ultrasonic waves.

Cleaning tank: usually made of stainless steel, which is corrosion-resistant and easy to drain.

Heating system (optional): Heat the cleaning solution (generally 40-60℃) to enhance the cleaning effect.

Filtration circulation system: filter the impurities in the cleaning solution and extend the service life.

3. Selection of cleaning liquid

Water-based cleaning agent: suitable for most magnetic materials, environmentally friendly and low cost, rust inhibitor can be added.

Organic solvents (such as alcohol): used to remove stubborn oils, but attention should be paid to flammability and material compatibility.

Acidic/alkaline solution: For the oxidized layer or specific pollutants, the concentration and time should be strictly controlled to avoid corrosion.

4. Applicable types of magnetic materials

Permanent magnetic materials: neodymium iron boron (NdFeB), samarium cobalt (SmCo), ferrite, etc.

Soft magnetic materials: silicon steel, iron-nickel alloy (Pomo alloy), amorphous nanocrystals, etc.

Others: magnetic powder core, magnetic film, magnetic encoder, etc.

5. Advantage

Efficient cleaning: It can clean pollutants in complex shapes, pores and gaps.

Non-contact: Avoid physical friction to damage the surface of the material.

Automation integration: can be combined with conveyor belts and robotic arms to achieve batch processing.

6. Notes

Ultrasonic parameters: Excessive power may cause microcracks in magnetic materials (especially neodymium iron boron).

Drying and anti-rust: After cleaning, it needs to be dried quickly, and some materials need to be protected by vacuum or inert gas.

Environmental protection and safety: Organic solvents need to be equipped with explosion-proof measures, and waste liquids need to be treated in compliance.

7. Application scenarios

Electronics industry: magnetic head, sensor, speaker magnetic steel.

Energy field: motor rotor, wind power permanent magnet.

8. Buying s estions

Select the frequency and power according to the characteristics of the material (size, magnetic strength, brittleness).

Priority is given to equipment with temperature control, filtration system and anti-rust functions.

Customized requirements (such as inert gas protection) need to be communicated with suppliers.
