Alternative to dry ice cleaning: the laser


LaserComercial 19/08/2021

Dry ice blasting is also known as cryogenic blasting. It is a deep cleaning technique used in some industries. It consists of using grains of dry ice ice (CO2 in solid state) to make them impact against a material with contaminants and dirt in order to clean thoroughly and effectively. It is a popular method, but now there is an alternative that has many advantages over dry ice cleaning: laser cleaningThe truth is that with dry ice the material is damaged since the temperature of the ice is very different from that of the surface, for this reason some users would consider another method.

Why is laser cleaning better? We are going to know how works this innovative technique.

Pros and cons of dry ice

Dry ice cleaning is quite an expensive process. Blasting material is expensive and a lot of energy is consumed during the process. It is true that it does not leave other residues after the process since the ice evaporates and does not accumulate in the environment. It is also a very versatile process and usually effective on different surfaces. On the other hand, dry ice must be stored properly and not for long, it must be kept at very specific temperatures. Dry ice is an imprecise process with more complex operability than lasers. It should also be taken into account that it is a process that the user must protect the body very wella protective suit, helmet, goggles and hearing protection are essential to work with dry ice.

Why choose laser over dry ice blasting

And what does laser cleaning offer us? To start with, laser cleaning laser cleaning evaporates dirt and impurities from a material through a process known as ablation. This type of laser machine can clean different types of dirt indoors and outdoors. It is a very versatile and configurable equipment; we can adapt the laser energy to each case. It is a non-contact and clean process, this makes it suitable for many more types of sectors, such as food.

Laser cleaning Laser cleaning does not require great protections. The user works with a comfortable laser gun that allows easy handling of the laser on the surface to be cleaned. It is very important to protect your eyes from laser light with suitable glasses, but it does not require a full suit. Laser cleaning also it offers us a great precision pointoffers us a high degree of precision, if required, we could even clean paint layer by layer.

A very interesting aspect of laser cleaning is the non-contact cleaning: the part and the substrate that we clean remains intact,, without any affectation.

At the moment of When choosing our appropriate laser cleaning equipment our appropriate laser cleaning equipment we must take into account the different models that exist. Laser cleaning machines have a fiber laser and the different models are classified according to their power. These machines can go from 100W to 1500W, and this will mark their effectiveness depending on the type and amount of dirt.

Laser cleaning is very suitable for materials such as:

  • Metals
  • Stone
  • Ceramics

The laser can clean:

  • Oxide
  • Paint
  • Oils
  • Grease
  • Food dirt
  • Resins
  • Spots
  • Coatings
