If you would like\u00a0delicate removal of surface coatings and do not want\u00a0any damage to the base material,\u00a0fiber\u2002laser\u2002cleaning\u2002machine<\/a>\u00a0would be\u00a0the perfect choice.\u00a0Laser cleaning can be applied to various materials including metals, composites, plastic, rubber\u00a0and stones. Coatings such as paint, varnish and rust can be cleaned with ease.\u00a0Laser paint removal<\/a>,\u00a0to be sure can\u00a0help update and reuse the material with paint you no longer needed.<\/p>

The traditional\u00a0methods for paint removal involves the use of chemical reagent\u00a0or abrasive media blasting. These methods are quite\u00a0time consuming, leaving damage\u00a0on the base material\u00a0and cause\u00a0extra\u00a0costs such as purchasing and safe disposal of the chemical solvents.\u00a0These\u00a0issues bring us a better solution –\u00a0laser cleaning equipment! How do we use it\u00a0for paint removal?\u00a0\u00a0To understand this, we\u00a0must first understand the cleaning mechanism of\u00a0laser cleaning equipment<\/a>.<\/p>

The cleaning process of\u00a0laser cleaning equipment<\/a>\u00a0depends on the light pulse generated by the laser, which is based on the optical physical reaction caused by the interaction between the high intensity beam, the short pulse laser and the polluted\u00a0layer.\u00a0Laser cleaning equipment plays\u00a0a crucial\u00a0role in many industries, such as automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, building external wall cleaning, protection of cultural relics, circuit board cleaning, precision parts processing and manufacturing and LCD cleaning. For example, laser cleaning systems have long been used in the aviation industry. The surfaces of the aircraft have to be repainted after a certain period of time, but the old paint has to be completely removed before the repaint. The traditional mechanical\u00a0paint removal<\/a>\u2002method would do damage to the metal surface of aircraft, which brings hidden danger to the safety of flight. With multiple\u00a0laser cleaning equipment\u2002<\/a>working simultaneously, the paint layer can be completely removed from the surface of an A320 Airplane in two days without damaging the metal surface.<\/p>

The paint applied to the surface of the metal acts as a special layer\u00a0to\u00a0protect the metal from corrosion and oxidation.\u00a0In order to carry out effective cleaning on the premise of ensuring the safety of the substrate material, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly\u00a0controlled.<\/p>

Each laser pulse removes a layer of pollution of a certain thickness.\u00a0\u00a0If the fouling layer is thick, multiple pulses are required for cleaning.\u00a0\u00a0The number of pulses required to clean the surface depends on the degree of surface contamination.\u00a0\u00a0An important result of the two thresholds is the self-control of cleaning.\u00a0\u00a0Light pulses whose energy density is higher than the first threshold will remove contaminants until they reach the substrate.\u00a0\u00a0However, because its energy density is below the destruction threshold of the substrate material, the substrate is not damaged.<\/p>

Based on the above\u00a0theories, when the\u00a0laser cleaning equipment\u2002<\/a>is used for paint removal\u00a0on the metal surface, the threshold value should be controlled appropriately. To achieve good quality,\u00a0laser paint removal<\/a>\u00a0needs\u00a02-3 steps. Firstly, a main pass using long pulse duration\u00a0and high pulse energy removes the majority of the paint layer. For the second pass, the remaining paint coating can be removed by short pulses and high scanning speeds without damaging the substrate. If necessary,\u00a0second pass can always be repeated. Finally an optional third pass to improve surface quality.<\/p>
