What is the laser cleaning method

4 ways to use a laser cleaning machine

There are 4 ways to use a laser cleaning machine. Normaltan China will explain this in detail to you.

First of all, let’s take a look at the principle of laser cleaning. Laser cleaning is the use of laser pulses to irradiate the surface of the workpiece to remove the attachment or surface coating on the surface of the workpiece. The impurities on the surface of the workpiece are evaporated instantly. Through the adjustment of equipment parameters, only impurities on the surface of the workpiece are removed without damage to the workpiece.

Next, NORMALTAN CHINA will introduce 4 ways to use the laser cleaning machine.

  1. Laser direct cleaning

The impurities on the surface of the workpiece generate plasma due to the absorption of the laser beam, thereby generating shock waves to remove the impurities. This is also the most direct method to remove the deposits on the surface of the substrate by laser radiation.

  1. Inert gas purge

To prevent the workpiece from being oxidized during laser cleaning, we can use inert gas.

When the laser irradiates the surface of the workpiece, the impurities are immediately stripped from the surface of the workpiece, and all the impurities on the surface are blown away by the inert gas.

  1. Liquid film cleaning

A liquid film is placed on the surface of the workpiece and impurities are removed by laser radiation. When the liquid film is irradiated by laser light, it will heat up rapidly and vaporize. The dirt on the surface of the substrate will become loose, to achieve the purpose of removing impurities.

  1. Laser + chemical cleaning

The surface impurities are loosely separated by laser, and then the surface is cleaned by non-corrosive chemical methods to achieve the purpose of decontamination. This cleaning method is mainly used for the cleaning of stone cultural relics.

What is the laser cleaning method?Laser cleaning has a positive impact on environmental protection and safety. Laser cleaning has the characteristics of no grinding, non-contact, and no thermal effect, and is more reliable and effective than traditional cleaning methods. The above laser cleaning method is selected according to the material of bonding material.
