At present, the cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but their application is greatly restricted under the constraints of environmental protection and the requirements of the high-precision market. The laser rust cleaners has obvious advantages in various industries. Laser cleaning has obvious advantages compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning, and high-frequency ultrasonic cleaning. The following describes the cleaning technology uses of the laser cleaning machine.
Laser cleaning technology uses nanosecond or picosecond pulsed lasers to irradiate the surface of the workpiece to be cleaned, so that the surface of the workpiece absorbs the focused laser energy instantly, forming a rapidly expanding plasma (a highly ionized unstable gas), making it The surface oil stains, rust spots, dust residues, coatings, oxide layers or film layers are vaporized or peeled off, so as to efficiently remove surface attachments.
The cleaning technology of the laser cleaning machine is efficient, fast, and low-cost, and the thermal load and mechanical load generated on the substrate are small, and the cleaning is non-damaging; the waste can be recycled and there is no environmental pollution; it is safe and reliable, and does not harm the health of the operator; A variety of coatings with different thicknesses and different compositions; the cleaning process is easy to realize automatic control, and remote control cleaning can be realized.
Typical applications of laser cleaning include: mold cleaning, industrial rust removal, old paint and film removal, pre-welding and post-welding treatment, deesterification of precision parts, decontamination and deoxidation of electronic components, and cultural relics cleaning. Widely used in metallurgy, molds, automobiles, hardware tools, transportation, construction home appliances, machinery and other industries.
In the field of industrial applications, laser cleaning objects are divided into two parts: the substrate and the cleaning object. The substrate mainly includes the surface contamination layer of various metals, semiconductor wafers, ceramics, magnetic materials, plastics, and optical components. The cleaning objects mainly include facing In the industrial field, rust removal, paint removal, oil removal, film/oxidation removal, and resin, glue, dust and slag removal are widely used. Wuhan Ruifeng Optoelectronic Laser is one of the first batch of laser equipment manufacturers, with more than ten years of R&D and production experience, leading peer companies in technology and integration. Since its establishment, the company has always paid attention to the research and development of laser technology and the development needs of customers, and is committed to providing each customer with complete material processing solutions.
Laser cleaning will not only cause damage to the object to be cleaned, but will also not cause pollution to the environment. The cleaning range includes: part combination, surface cleaning before welding, paint removal of metal surface paint (full paint removal, semi-paint removal) Or paint removal on designated parts), derusting of steel surfaces, and cleaning of various industrial products or molds. The application fields include mold industry, automobile manufacturing, shipbuilding, food processing, sewage treatment, rubber tires, petrochemicals, etc. The maturity and popularization of laser cleaning technology has made the world’s surface treatment technology a qualitative leap, made the concept of “green” cleaning deeply rooted in the hearts of the people, and improved the surface treatment and industrial production standards of various industries in China. The continuous improvement of laser cleaning technology will fully help the country 2025 China Manufacturing strategic planning.
The above is the cleaning technology application of laser cleaning machine. As an advanced technology in laser manufacturing, laser cleaning technology has great application potential in industrial development. It is of very important strategic significance to vigorously develop laser cleaning technology.
