Environmental&Non-destructive,Laser Paint Removal Process
Painting is an important means of protecting metal materials in the industry, and it can protect, decorate, mark and other special effects on objects. Due to the long-term erosion of air, moisture and temperature, the paint is prone to fall off, affecting the appearance, and the ability to prevent metal corrosion will also decrease. It needs to be repainted regularly, and paint removal is the most important process before repainting.
Laser Cleaning
The laser paint removal process is to irradiate the paint part to be cleaned with a laser beam, so that the paint layer on the surface will evaporate or expand and peel off instantaneously, so as to achieve a clean process.Features of Laser Cleaning
1.Non-contact: It is convenient to clean the irregular parts, holes, grooves and other parts that are difficult to reach by traditional cleaning methods.2.Fine Processing: The paint on a certain part of the substrate can be selectively cleaned.
3.Environmental Protection & Pollution-free: There is no need to use chemical reagents; the solid powder layer produced by paint removal can be recycled through the dust collection system.
4.Clean without Damage: It can remove various substrate surface coatings and achieve a high degree of cleanliness. At the same time, the short-term impact will not damage the substrate surface.
5.Low Cost: The pulse laser used in the laser cleaning machine has a long service lifespan, usually up to 100,000 hours, with stable quality and good reliability. There is no consumption of consumables during use, and only the lenses need to be cleaned or replaced regularly in the later period. The maintenance cost is low and almost no maintenance is required.
Application of Laser Paint Removal Technology
Laser paint removal equipment has a wide range of applications, covering aerospace, automobile manufacturing, rail transit, shipbuilding, steel manufacturing, and electronics industries.
Aerospace
In the field of aerospace, aircraft surface paint removal has become an important part of aircraft overhaul. Laser paint removal technology can quickly and effectively remove the surface paint layer of aircraft composite parts, which solves the traditional chemical paint removal methods that are difficult to deal with chemical products and reagents on the substrate causing additional damage and other shortcomings, and greatly shorten the maintenance cycle and reduce maintenance costs.Automobile Manufacturing Field
Selective paint removal is one of many applications for laser cleaning machine. In the automotive industry, it is sometimes necessary to remove the top layer of paint while protecting the primer. Usually, the weathered coating on the top of the vehicle needs to be completely removed before applying new paint. Since the physical and chemical properties of the uppermost paint are different from those of the primer, the power and frequency of the laser can be set to remove only the uppermost paint. The laser has no mechanical, chemical or thermal effect on the primer, so the primer can still remain intact. This ensures the corrosion resistance of the primer.
Rail
During the overhaul and maintenance of rail transit equipment, there are a large number of parts that need to be cleaned. The key components installed or suspended outside the vehicle body, such as axles, gearboxes, brake discs, etc., need to be cleaned of dirt, rust, paint and other dirt. Due to the variety of dirt, different cleaning methods are required, and even the parts are disassembled, and the cleaning process is long. There is also an urgent need for an environmentally friendly and efficient cleaning method.Laser cleaning can not only effectively remove rust, oil stains, paint, and oxide layers on the surface of the material. It can also customize backpack-type, movable and fixed equipment according to customer needs to meet the cleaning needs of different occasions in rail transit.
Shipbuilding
With the rapid growth of the Chinese economy and foreign trade, the number of ships in China has increased substantially, and most of them use sandblasting to remove paint, causing serious pollution to my country's rivers and offshore oceans. Laser cleaning technology solves the shortcomings of traditional shot peening cleaning methods such as large amounts of noise, pollutants and potential hazards to construction personnel, making cleaning more green and environmentally friendly.
