As a new type of surface treatment technology, laser cleaning has received widespread attention in today's increasingly strict environmental protection policies, and the United States and Europe are leading the world in the field of laser cleaning. China is one of the few developers and practitioners of laser cleaning technology in the world, in the fields of laser rust removal, laser paint removal, laser degreasing, etc., and has launched a very cost-effective mature product, which has a certain influence in the world.
In 1964, American scientists inadvertently scanned a piece of paper with a laser, and there were words written in ink on the paper, and the words magically disappeared after laser irradiation, which was the first time that a laser could remove specific substances. In 1971, the American scientist Bedair first proposed the concept of laser cleaning. In 1974, American scientists did a number of experiments on laser cleaning cultural relics, and the results were very good. In 1975, Soviet scientists used a laser to clean the oil floating on the water surface, and the effect was excellent, and the laser cleaning was applied to the practice of large-scale pollutant treatment for the first time. In 1987, American scientist Beklemvshev studied laser removal of tiny particles on the surface of semiconductor materials, and the experiment was successful and applied for a patent. In 1992, a church in the United Kingdom was successfully cleaned using laser cleaning technology, and since then, a number of cultural heritage buildings in Europe have been successfully cleaned. In 1995, Germany used 2,000 watts of CO2 laser paint to remove paint from aircraft, using three machines to perfectly remove the paint layer of an aircraft with a surface area of 1,600 meters in three days. After entering the 21st century, the application scope of laser cleaning technology has been further increased, from the removal of nano-level tiny particles, to the removal of ship and aircraft coatings, from the removal of inorganic matter to organic pollutants, from the cleaning of transparent materials to opaque materials, from plane structure to complex structure, and the research scope of laser cleaning is very wide. Laser cleaning technology has developed into an irreplaceable technology and plays a huge economic benefit in specific fields.
It has been more than half a century since the discovery of laser cleaning in 1964, why has the laser cleaning machine suddenly "flown into the homes of ordinary people" in recent years?In recent years, with the mass production of high-power lasers in China, it has dropped to one-tenth of 10 years ago, and the laser cleaning equipment has dropped significantly, and the cost of laser cleaning has declined, and it has surpassed the traditional cleaning process in some fields. For example, laser rust removal, laser cleaning mold and other fields can better solve problems at a lower cost, which is favored by business owners. And its potential has not been fully tapped, and its maximum power has not been released, how can such a good cleaning method not attract people's attention?
