Dry ice cleaning is a process in which dry ice is used in a combined system with compressed air to clean surfaces.
It is a non abrasive cleaning method, that will not penetrate the surface of the object that it is shot at, but it will still remove surface contaminates. There is no secondary waste as the dry ice will sublimate into CO2 gas.
Dry ice is CO2 in a solid state. It is formed when CO2 liquid is release in a controlled environment. The normal temperature of dry ice is about -80 degrees Celsius.
Dry ice have the physical characteristic that is called sublimation. Sublimation is the process in which a solid change state directly from a solid into a gas as shown in this picture.
During the process, dry ice particles get propelled with high pressure air.The dry ice nozzle is aimed at the surface that needs to be cleaned. The air propelled dry ice pellets hits the surface. Due to the temperature; cold (-80 degrees Celsius) and force (adjustable on the dry ice machine and compressor) at which it hits the surface, contaminants on the surface will crack,the O2 part of the CO2 will cause an explosion, this will rip the contaminants of the surface leaving the surface without any contaminants.
