  We all know that Shandong rust removal can be cleaned with detergent, but can we understand laser cleaning? Laser is a light source with high brightness, high directivity, high monochrome and high coherence, which is incomparable with ordinary light sources. For the use of laser can clean Shandong rust, the effect of laser cleaning is better. Now let me tell you about the effect of Shandong rust laser cleaning?
  In terms of its cleaning mechanism, laser cleaning can be divided into two categories: one is the use of cleaning substrate (also known as matrix) and surface adhesion (fouling) for a certain wavelength of laser energy, with very different absorption coefficients. Some of the laser energy radiated to the surface of the object is absorbed on the surface of the object to make it heated or vaporized, or to expand instantaneously, so that the vapor on the surface of the object can flow out from the surface of the object to achieve the purpose of cleaning.
  The substrate absorbs very little energy at that wavelength and will not be destroyed. For this kind of laser cleaning, choosing the appropriate wavelength and controlling the laser energy is the key to the final safe and efficient cleaning. The other is the cleaning method under the condition that the laser energy absorption coefficient is different between the substrate and the surface, or the substrate is more sensitive to the acid vapor formed by the coating when heated, or the coating will attack toxic substances when heated.
  This method usually uses high power, high repetition pulse laser to shock the cleaned surface and convert part of the beam into acoustic wave. After the sound wave hits the hard base surface, part of the near back and laser attack incident sound wave micro-explosion, coating is destroyed, pressed into powder, and then destroyed by the vacuum pump, while the underlying substrate will not be destroyed.
  Laser cleaning of Shandong rust has its advantages, cleaning efficiency is higher, and cleaning is very clean, save a lot of trouble than manual cleaning. Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid-solid impact cleaning and high frequency ultrasonic cleaning, laser cleaning has obvious advantages. It has high efficiency, convenience and low cost, less attack on thermal and mechanical loads of substrates, no damage during cleaning, recyclable waste without polluting the environment, safe and reliable, and does not endanger the health of operators. Laser cleaning of rust in Shandong Province will be popularized and applied in the future.
