In recent years, as people’s awareness of environmental protection has increased, it has brought huge challenges to the development of the cleaning industry worldwide. Various cleaning technologies that are conducive to environmental protection have emerged, and laser cleaning technology is one of them. The so-called laser cleaning technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece to cause the dirt, rust, or coating on the surface to evaporate or peel off instantly, and effectively remove the adhesion or surface coating on the surface of the cleaning object at high speed, so as to achieve a clean process. It is a new technology based on the interaction effect of laser and substance. It is different from the traditional mechanical cleaning method, chemical cleaning method, and ultrasonic cleaning method (wet cleaning process). It does not require any CFC organic solvents that destroy the ozone layer and is pollution-free. , No noise, harmless to the human body and environment, it is a kind of “green” cleaning technology. 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. It is efficient, fast, and low-cost. The thermal and mechanical loads on the substrate are small, and the cleaning is non-damaging; the waste is recyclable, without environmental pollution; it is safe and reliable and does not harm the operator’s health; it can remove a variety of different thicknesses and differences. The coating of the components; the cleaning process is easy to realize automatic control, and realize remote control cleaning, and so on.
Laser cleaning is an emerging industrial cleaning solution. Compared with traditional cleaning solutions, laser cleaning is more environmentally friendly and has a wider range of applications. It can be used to clean the oil, oxide, and rust layers on the surface of industrial equipment or processed industrial parts and airport runways. Rubber birthmark cleaning can also be used to clean the paint weld marks on the deck surface. In addition, because laser cleaning has little damage to the basic layer of the object, it has gradually become the mainstream solution for cleaning metalware, porcelain, and other cultural relics in cultural preservation work.
The principle and method of laser cleaning The laser is characterized by high directivity, monochromaticity, high coherence, and high brightness. Through the focus of the lens and the Q switch, the energy can be concentrated into a small space and time range. In the laser cleaning process, the following characteristics of the laser are mainly used: 1. The laser can achieve a high concentration of energy in time and space, and the focused laser beam can generate thousands of degrees or even tens of thousands of degrees near the focal point. High temperature causes the dirt to evaporate, gasify or decompose instantaneously. 2. The divergence angle of the laser beam is small, and the directivity is good. The laser beam can be gathered into spots of different diameters through the focusing system. Under the same conditions of laser energy, control laser beam spots with different diameters. 3. The energy density of the laser can be adjusted to make the dirt expand by heat. When the expansion force of the dirt is greater than the adsorption force of the dirt to the substrate, the dirt will be separated from the surface of the object. Our laser cleaning machine is an advanced product in the laser system. We use a very stable and durable fiber laser light source without the need for lamp replacement. This new type of Q-switched laser (also known as ultra-pulse laser) provides an excellent tool for mold cleaning, pre-processing of parts joining and removal of cladding layers, and other applications that require power and accuracy. The perfect laser design also provides easy solutions for various applications in the industry. Our machines provide a high-efficiency, stable, and almost maintenance-free operating system in terms of structure and design. The self-cooling laser light source not only produces no pollutants, no consumables but is also easy to set up and operate. The system is easy to move and is designed for mold cleaning on the vulcanizer. The system can also clean any form of mold or parts of active molds, such as active blocks or side plates, off-line. The mold to be cleaned can be at any temperature. The vulcanizing machine can start vulcanization immediately after mold washing is completed. In some cases, it is necessary to disassemble and lift the lower half of the two mold halves for cleaning in the vulcanizer.
