The Present and Future of Laser Rust Removal

Table of Contents

Today’s manufacturing industry is developing rapidly, and the application scale of various mechanical and electronic products has greatly increased. However, these devices require some maintenance before assembly and after a period of operation, including cleaning some metal materials or parts, including rust removal and paint removal. Traditional rust removal and paint removal processes, such as mechanical friction rust removal, chemical corrosion cleaning rust removal, strong impact cleaning rust removal, high-frequency ultrasonic cleaning rust removal, etc., are time-consuming, cannot be automated, and often have harmful effects on the environment .

 Also, there is no reliable way to measure cleaning effectiveness. In contrast, laser rust removal has no pollution, no consumables, low cost, high efficiency, no contact, no stress, no damage, good controllability, and rust and laser rust removal tools can be selected for precise cleaning, and can clean dangerous areas that are difficult to reach, etc. Advantages, laser rust remover tool is considered to be the most reliable and effective solution to cleaning problems in the future.

The mechanism of action of laser rust removal

The laser rust removal with narrow pulse width and high power density to act on the surface of the object to be cleaned. Under the combined action of rapid optical vibration, vaporization, decomposition and plasma stripping, the dirt is separated from the substrate to achieve surface cleaning. At present, there are three typical laser cleaning methods: laser ablation cleaning, liquid film assisted laser cleaning and laser shock wave cleaning. Among the above three methods, the laser ablation cleaning method has simple operating conditions and is the most widely used. Selecting the appropriate laser type and adopting optimized process parameters can remove various coatings, paints, particles or dirt. Although the other two methods also have their own advantages, their application is still in the research stage and there is no large-scale promotion.

Laser rust removal tools is generally composed of a laser, a beam transmission shaping unit, an automatic control operating system, a cleaning quality inspection and protection unit, and a displacement platform.

Application fields of laser rust remover tool

Laser rust remover tool research started in the mid-1980s, but did not really enter industrial production until the early 1990s. laser rust removal tools has been well applied in mold cleaning, material surface treatment, paint removal and rust removal of large equipment and precision machinery, etc. . In addition, European countries generally retain a large number of historical relics and ancient buildings. Many churches, castles, universities, museums, sculptures, etc. have hundreds or even thousands of years of history. Europeans attach great importance to the protection and restoration of these “antiques”. Since the mid-1990s laser rust removal technology has already begun to be used in the restoration and decontamination of cultural relics.
