In-depth analysis of the principle of dry ice cleaning

Dry ice blast cleaning, also known as cold spray, uses compressed air as the power and carrier, and dry ice particles as the accelerated particles. It is sprayed onto the surface of the object to be cleaned through a special spray cleaning machine. The momentum change, sublimation, melting and other energy conversion of the high-speed moving solid dry ice particles are used to quickly freeze the dirt, oil, residual impurities, etc. on the surface of the object to be cleaned, so that they condense, become brittle, and are peeled off, and are removed with the airflow at the same time. It will not cause any damage to the surface of the object to be cleaned, especially the metal surface, nor will it affect the finish of the metal surface.
