Current Status of Laser Cleaning Industry
Nowadays, rust is an inevitable existence of some metal products. In order to make the product beautiful and continue to use, it has to be derusted. As people begin to pay more and more attention to the cleaning industry, more and more people have begun to use laser rust cleaning machines to clean up rust and other stains. Laser cleaning There are various cleaning methods in the traditional cleaning industry, most of which use chemical agents and mechanical methods for cleaning. Laser rust cleaning machine can not only be used to clean organic pollutants, but also inorganic substances, including metal rust, metal particles, dust, etc.
The principle of The rust laser removal machine is to irradiate the surface of the workpiece with high-frequency and high-energy laser pulses. The coating layer can instantly absorb the focused laser energy, so that the oil stains, rust spots or coating on the surface can be evaporated or peeled off instantly, and the surface attachment can be effectively removed at a high speed. The cleaning method of the surface coating or the surface coating, and the laser pulse with a short action time will not damage the metal substrate under the appropriate parameters. Because the laser cleans the workpiece without contact, it is very safe to clean the precision workpiece or its fine parts, and its accuracy can be ensured. Therefore, laser cleaning has unique advantages in the cleaning industry.
Advantages and Disadvantages of Traditional Metal Derusting Methods
Metals are widely used in the industrial field, and all kinds of metal materials can be seen almost everywhere in our lives. However, if metal is left in the air for a long time, it will inevitably rust. Derusting of metals has become a major problem that must be faced in the use of metals. Traditional metal rust removal methods include:
1. Manual rust removal method: Use scraper, hand hammer, steel brush, grinding wheel and other tools to knock, shovel, grind, scrape, etc. to remove rust.
Disadvantages: low rust removal efficiency, harsh operating environment, high labor intensity, generally can only remove loose rust and ineffective old coatings, but cannot remove all oxide scales.
2. Mechanical rust removal method: Use portable electric grinding wheels, electric brushes, pneumatic brushes, rust removal guns, etc. to effectively remove rust and dirt by impact and friction. Two methods, spraying and shot blasting, are widely used.
Disadvantages: environmental pollution is heavy.
3. Chemical treatment method: Use acid liquid to chemically react with the rust (oxide) on the surface of the metal to be cleaned to dissolve it in the acid liquid. In addition, the hydrogen generated by the action of acid and metal makes the oxide scale mechanically fall off.
Disadvantages: The chemical immersion method requires the workpiece to be immersed in the solution. Therefore, this method cannot be used for the rust removal of some large structures and equipment; it may corrode the metal material matrix.
