Dry ice blasting is widely used around the world because it is an environmentally friendly cleaning technology;

The principle of dry ice blasting machine:

  1. The temperature of the dry ice is -78.5 degrees Celsius. It is pressurized by compressed air and hits the surface of the object to be cleaned, instantly freezing the dirt on the surface.
  2. After the frozen dirt expands with heat and contracts with cold, a transverse shear force is formed, and cracks appear on the surface of the frozen dirt.
  3. The subsequent dry ice enters the object to be cleaned through the cracks, and at the same time, the dry ice begins to expand by 500 times to undergo a sublimation reaction.
