Laser cleaning vs blast cleaning

Laser cleaning:

Laser cleaning mainly uses a laser beam to work on the workpiece with rust stains. The high-frequency high-energy laser pulse irradiates the surface of the workpiece, and the coating layer can instantly absorb the focused laser energy, making the surface oily, rust or coating. Instantaneous evaporation or peeling occurs, high-speed and effective cleaning method to remove surface attachments or surface coatings, and laser pulses with short action time will not damage the metal substrate under appropriate parameters.

Sandblasting cleaning:

It mainly uses compressed air as the power to form a high-speed jet beam and then spray it to the surface of the workpiece to be treated at a high speed, so that the surface of the workpiece can be changed.

Both laser cleaning and sandblasting are mainly for the treatment of various types of pollutants such as rust stains on some workpieces, but the efficiency and mode of action of the two are different.

  • Laser rust removal can be carried out directly during processing, while sandblasting machine needs to remove excess material on the surface of the workpiece to achieve better rust removal effect. In contrast, the processing efficiency of laser rust removal is higher than that of sandblasting machine;
  • Secondly, the operation steps of the sandblasting machine are a bit cumbersome, not to mention the low efficiency, and sometimes it may damage the workpiece, not clean it cleanly, cause environmental pollution, etc., and laser rust removal is a kind of green, no damage. Cleaning and low-cost cleaning processing.

Laser rust removal does not require any chemicals, and the waste after rust removal is solid and harmless powder, which can completely solve the problem of environmental pollution caused by chemical rust removal;

Moreover, laser rust removal is a non-contact processing method, and there is no need to worry about damage or deformation of the workpiece.

Furthermore, the initial investment of the laser descaling system is high, but it can be used stably for a long time, with a service life of up to 10 years, low operating cost, high speed, high efficiency, time saving, and a quick return on investment.
In the long run, the cost is lower than the sandblasting method.

In contrast, the overall advantages of laser rust removal are higher than those of sandblasting machines, and the efficiency is also better!
