Laser Cleaning Machine Advantages
Jun 14, 2018

Metals are widely used in the industrial field. Almost all kinds of metal materials appear in our lives. However, if metals are placed in the air for a long time, they will inevitably rust.

The loss caused by metal corrosion is extremely significant. According to statistics of the American Metal Society, the global economic losses caused by metal corrosion account for 4% of the total value of production, and the metal scrapped due to corrosion accounts for 30% of the total output; China’s annual corrosion caused by metal corrosion The economic loss amounted to more than 3,000 billion.

Metal rust removal has also become a major problem that must be faced in the application of metals. Traditional metal rust removal methods include:

1, manual rust removal method

Use squeegee, hand hammer, steel brush, grinding wheel and other tools to knock, shovel, grind, scrape, etc. to remove rust.

Disadvantages: Low efficiency of rust removal, harsh operating environment, and high labor intensity. Generally, only loose rust and spent old coatings can be removed, and all oxide scales cannot be removed.

2. Mechanical rust removal method

The use of portable electric grinding wheel, electric brush, pneumatic brush, derusting gun, etc. use impact and friction to effectively remove rust and dirt. The most widely used are two methods of injection and shot blasting.

Disadvantages: Heavier environmental pollution.

3, chemical treatment

The chemical reaction occurs between the acid and the rust (oxide) on the surface of the metal to be cleaned, so that it is dissolved in the acid. In addition, the hydrogen generated by the acid and the metal causes the scale to mechanically fall off.

Disadvantages: chemical soaking method to immerse the work piece in the solution, so for some large-scale structure, equipment, rust removal, this method cannot be used; may be corrosion metal matrix.

Compared with the traditional rust removal method, the laser cleaning process has high efficiency and good effect, so that it does not damage the substrate, and thus it suddenly becomes the darling of metal rust removal.

The working principle of laser rust removal technology is also very simple. When the laser is applied to the iron chips, it will vaporize instantly. After the plasma is formed, the rust-removed part will be exposed to laser light because of the high reflectivity of the lower metal. It will not be damaged anymore, so this kind of laser rust removal method is efficient and safe, and even the corners of the parts, such as letters and bolts, can be perfectly cleaned.

The laser cleaning machine launched by MRJ-laser laser is a new generation of surface cleaning high-tech products. It is easy to operate, easy to integrate automatically, does not require chemical reagents, can fit curved surface cleaning, high cleanliness, high precision, high efficiency, environmental protection and safety. Reliable, almost no damage to the substrate surface, can solve a variety of problems that traditional cleaning cannot solve.
