Enameled wire is a main type of winding wire, composed of two parts: conductor and insulating layer. The bare wire is annealed and softened, and then painted and baked many times. But it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by raw material quality, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires vary, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.
The principle of laser cleaning is to use high-frequency and high-energy laser pulses to illuminate the surface of the workpiece, and the coating layer can instantly absorb the focused laser energy, causing oil stains, rust spots or coatings on the surface to be instantly peeled off, effectively removing surface adhesions or surface coatings at high speed. The cleaning method of the coating, while the short-acting laser pulse, under the appropriate parameters, will not harm the metal substrate.
After the first laser cleaning irradiation, the first layer of adhesive on the surface of the enameled wire is cleaned, revealing a layer of black part. After the second cleaning, the laser cleaning removes the black part, revealing the true color of the enameled wire. After cleaning, the cleaning effect can be clearly seen, and the laser cleaning does not cause damage to the material of the enameled wire.
Laser cleaning has the following advantages:
1. Green cleaning: without the use of any chemicals, the cleaned waste is solid and harmless powder, which can completely solve the problem of environmental pollution caused by chemical cleaning.
2. Non-destructive cleaning: non-abrasive, non-contact, and no damage to the substrate during cleaning.
3. Low-cost cleaning: The equipment consumes very little power during operation.
4. Precision and precision cleaning: It is possible to perform precision and precision cleaning on designated areas.
5. Automated cleaning: It can be equipped with automated equipment to achieve automated cleaning.
With the increasing awareness of environmental protection and safety, laser cleaning is widely used due to its non-grinding, non-contact, non-thermal effect and suitability for objects of various materials. At the same time, laser cleaning can solve problems that cannot be solved by traditional cleaning methods.
