The Disadvanges of Traditional Cleaning Methods

The main problems of traditional cleaning methods include: negative impact on the environment and wear on the substrate. The sandblasting system generates a lot of waste and damages the fine surface of the substrate; while cleaning with chemical solvents, it will generate potentially dangerous steam and liquid waste.
The shortcomings of traditional cleaning methods have prompted the application of laser technology in the field of surface cleaning. Because of the many advantages of laser cleaning, it has now become the most effective way to remove unwanted substances on the surface of materials.
Currently, pulsed laser cleaning and decoating systems are widely used in various fields, from removing vulcanized residues on tire molds and engraved surfaces by ablation, to peeling insulation from wires, and removing coatings from delicate surfaces.

Why Laser Can Clean Rust?

The pulsed laser cleaning process depends on the characteristics of the optical pulse generated by the laser source. It is based on the optical physical reaction caused by the interaction between the high-intensity beam, short-pulse laser and the pollution layer. The principle is as follows:

A) The laser beam emitted by the laser source is absorbed by the contaminated layer on the surface to be treated.

B) The absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), which generates shock waves.

C) The shock waves cause the pollutants to fragment and be removed.

D) The light pulse width must be short enough to avoid the heat accumulation that destroys the treated surface.

E) Experiments show that when there are oxides on the metal surface, plasmas are generated on the metal surface.

Plasmas are produced only if the energy density is above a threshold, which depends on the contaminant or oxide layer being removed. This threshold effect is important for effective cleaning without compromising the safety of the substrate. There is a second threshold for the emergence of plasma. If the energy density exceeds this threshold, the substrate material will be destroyed. In order to effectively clean the base material safely, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly between the two thresholds.

Each laser pulse removes a certain thickness of contamination. If the contamination layer is thick, multiple pulses are required for cleaning. The number of pulses required to clean the surface depends on the level of surface contamination. An important result of the two thresholds is the automation of the cleaning. Light pulses with an energy density higher than the first threshold will continue to remove contaminants until they reach the substrate. However, because its energy density is lower than the damage threshold of the substrate material, the substrate will not be damaged.
