What Affects the Rust Removal Efficiency of Laser Rust Removal Machines?

The rust removal efficiency of a laser rust removal machine mainly depends on its power and the thickness of the rust layer. For example, a 100-watt to 1000-watt laser rust removal machine can remove rust at a rate of 3 to 18 square meters per hour for a rust layer thickness of 50 micrometers; for a rust layer thickness of 100 micrometers, the efficiency is 2 to 9 square meters per hour; and for a rust layer thicker than 100 micrometers, the efficiency is 1 to 5 square meters per hour. Additionally, a 2000-watt laser rust removal machine can achieve an efficiency of about 32 square meters per hour, while a 1500-watt machine has an efficiency of about 25 square meters per hour. In practical operations, a 200-watt laser can achieve a rust removal efficiency of 6 to 10 square meters per hour.

Other Factors Affecting the Efficiency of Laser Rust Removal Machines

1. Material Characteristics:

Rust layers are loose and brittle, easily absorbing laser energy and heating rapidly, causing the oxide layer to crack, peel, or vaporize, resulting in faster rust removal. The composition and structure of the rust layer directly affect the laser's absorption rate, and more severe rusted areas often require more time to clean.

Paint layers are dense and have high adhesion, requiring more energy and time to decompose, resulting in lower paint removal efficiency. Different coating materials (such as paint, resin, etc.) have different absorption rates for laser, affecting the removal speed.

2. Interaction Between Laser and Material:

Rust layers can efficiently absorb laser energy, quickly removing rust. During interaction with the rust layer, the laser generates thermal and photochemical effects, rapidly causing the rust layer to vaporize or peel off.

Paint layers need to be penetrated and heated, resulting in lower paint removal efficiency, especially for thick coatings and multi-layer structures. Thick coatings often require multiple laser scans to be completely removed, increasing the complexity and time of the work.

3. Equipment Parameters:

The larger the fiber core diameter, the higher the rust removal efficiency. For example, the rust removal efficiency of a 100-micron fiber laser is about twice that of a 50-micron fiber laser. Increasing the fiber core diameter allows for a wider distribution of laser energy, covering a larger area and improving rust removal efficiency.

The higher the power of the continuous laser, the higher the efficiency. For example, 1000-watt, 1500-watt, 2000-watt, and even 3000-watt lasers have higher efficiency when processing materials such as metal steel structures and plates. High-power lasers can provide stronger energy output, quickly removing thick rust layers and hard coatings.

In summary, the rust removal efficiency of a laser rust removal machine is influenced by various factors, including equipment power, rust layer thickness, material characteristics, and equipment parameters. When selecting and using a laser rust removal machine, it is essential to consider these factors comprehensively to achieve the best rust removal effect and work efficiency.
