Blasting (cleaning) with dry ice is considerably more friendly not only to the materials, but also to the environment. Last but not least, it can be used flexibly, starting from the cleaning of painted surfaces with a coating, in the same way as in the case of traditional sandblasting, except without destruction of the surface. Another alternative use is the cleaning of fatty and heavily contaminated surfaces, even in places with very poor reachability. The great advantage is the sublimation of the cleaning media immediately after fulfilling its function.
Phase 1 – Kinetic – when the dry ice particles drifting in a pressurized air stream impact on the surface at the speed of sound. This breaks and removes the contaminants from the surface being cleaned.
Phase 2 – Thermal – the low temperature of the particles of dry ice (-79 °C) causes the cooling of the contaminant so that it becomes brittle and easily detachable from the surface being cleaned.
Phase 3 – Sublimation – the dry ice particles penetrate the contaminant and instantly sublimate (there is a change of physical state from solid state into gas). This leads to a 541-fold increase in the volume and an explosive effect that separates dirt from the surface being cleaned.
