Metals are widely used in the industrial field, and various metal materials can be seen almost everywhere in our lives, but metal will inevitably rust when placed in the air for a long time. Metal derusting has also become a major problem that must be faced in the use of metal. Traditional metal rust removal methods include:
1. Manual rust removal method: Use scrapers, hand hammers, steel brushes, grinding wheels and other tools to knock, shovel, grind, scrape, etc. to remove rust.
Disadvantages: The rust removal efficiency is low, the operating environment is harsh, and the labor intensity is high. Generally, only loose rust and expired old coatings can be removed, and all oxide scales cannot be removed.
2. Mechanical rust removal method: Use portable electric grinding wheels, electric brushes, pneumatic brushes, rust removal guns, etc. to effectively remove rust and its dirt by impact and friction. The most widely used methods are jetting and shot blasting.
Disadvantages: heavy environmental pollution.
3. Chemical treatment method: The acid solution is used to chemically react with the rust (oxide) on the metal surface to be cleaned, so that it is dissolved in the acid solution. In addition, the hydrogen generated by the action of the acid and the metal causes the oxide skin to fall off mechanically.
Disadvantages: The chemical immersion method needs to immerse the workpiece in the solution, so this method cannot be used for rust removal of some large structures and equipment; it may corrode the metal material matrix.
Compared with the traditional rust removal method, laser cleaning has high processing efficiency and good effect, so that it does not hurt the substrate, so it has suddenly become the darling of metal rust removal.
The laser cleaning equipment launched by Shengtong Intelligent Laser is a new generation of high-tech products for surface cleaning. It has the advantages of easy control, easy automation integration, no chemical reagents, surface cleaning, high cleaning cleanliness, high precision, high efficiency, environmental protection, and safety. Reliable and almost no damage to the surface of the substrate, it can solve many problems that cannot be solved by traditional cleaning.
Lightweight design, integrated integration, easy to carry to any work area manually, to achieve target selection and positioning cleaning; non-contact cleaning work, no damage to the substrate, no pollution, no follow-up processing.
