Laser Cleaning - Laser Beauty in Industry

Laser cleaning is an efficient and green new cleaning technology. Compared with chemical cleaning, laser cleaning does not require chemicals and cleaning solutions; compared with mechanical cleaning, laser cleaning, no contact, no stress, very little damage to the substrate, so there are many areas of application with great prospects.
Ship cleaning
Ship cleaning is mainly divided into two parts: production cleaning and maintenance cleaning.
Production cleaning refers to the production of ships when the steel plate and other materials for cleaning, in the past this process is usually used in the traditional sandblasting treatment, and with the increasingly stringent environmental regulations, sandblasting cleaning brought about by the dust problem can not be ignored, our country, including a number of countries are prohibited in the open environment to use the dry air sandblasting rust removal technology. The use of laser cleaning can effectively avoid this problem.
Maintenance and cleaning refers to the maintenance and rust and paint removal work on the old ship after traveling for a period of time. Equipment such as seawater filter covers, motor seals, deck structures, etc., are prone to various kinds of rust, salt stains and biological contamination after long-term immersion, and laser cleaning will be able to solve these problems on a large scale and with high efficiency in the future, reducing the time that the ship is stranded in the harbor.
In 2021, the ship cleaning industry market has reached about 6.8 billion U.S. dollars. Although the current laser cleaning equipment used in the marine industry, but also faces the double challenge of power and price, but recently, Ruike laser and other companies are continuing to invest in the ship laser cleaning industry, to promote the innovation of laser cleaning equipment.
Rail cleaning
Railroad is an important national infrastructure, but also the artery of the national economy, high-speed rail has become one of the representatives of "Made in China". Seamless railroad rails are exposed to the outdoors all year round, under the wind and sun, there are inevitably rust and dirt, forming a safety hazard.
For seamless rail cleaning, need to be as short as possible, as efficient as possible, so as not to affect the normal operation of the railroad; the need to move convenient enough to be able to stretch thousands of kilometers on the railroad use; need to have a universal, can be used in different natural environments, climatic conditions. The traditional manual grinding wheel grinding, inefficient at the same time may also damage the rail, and laser cleaning is to meet the above needs.
Laser rail cleaning equipment runs fast, up to 60 miles per hour in UK railroad experiments. The efficiency is further improved by the use of integrated cleaning and welding equipment and digital systems, which can clean organic and inorganic substances and other different dirt, suitable for different cleaning scenarios.
For various reasons, the laser wants to completely replace the traditional way in rail cleaning, there is still a long way to go. Taking Xiangming Laser as an example, the shipment of the integrated cleaning and welding equipment launched by it has reached 50 to 60 units in 2021, and entered into mass production, which will help high-speed rail cleaning to be further upgraded in an intelligent way.
Battery cleaning
In the field of new energy, the requirements for laser cleaning are more precise. Nowadays, laser cleaning has been heavily utilized in the three power battery production processes of pole piece manufacturing, electric core manufacturing and battery assembly.
When welding power batteries, the overall structural strength needs to be ensured, and it is necessary to clean up the liquid leakage and oxidized layer residues near the liquid injection holes. Through the precision treatment of laser cleaning, the effects of liquid leakage and oxidized layer can be reduced to a considerable extent without affecting the structure of the battery.
Similarly, in the manufacture of pole pieces, coatings and dirt near the pole lugs need to be cleaned off first to ensure the stability of the fluid collector. The pole piece material is relatively fragile, the use of mechanical or chemical cleaning will lead to the structure of the pole piece affected, and it is difficult to ensure the effectiveness of the coating cleaning. The use of laser cleaning can improve the battery energy density, while maintaining battery stability and optimizing the overall charging and discharging performance.
In the battery assembly, the battery pack tray weld, the battery pack cover electrophoresis paint, protective bottom plate, etc. also need to clean. The use of laser cleaning of these structures, on the one hand, can reduce environmental pollution, on the other hand, can protect the line, to prevent power battery quality problems.
