1, dry ice cleaning, is a method used to clean the dirt.
2, dry ice cleaning (dry ice blast cleaning), also known as cold spray, is to compressed air as the power and carrier, dry ice particles as the accelerated particles, through a special jet cleaning machine sprayed to the surface of the object to be cleaned, the use of high-speed movement of solid dry ice particles of the momentum change (Δmv), sublimation, melting, and other energy conversions, so that the surface of the object to be cleaned. Dirt, oil, residual impurities, etc. on the surface of the object to be cleaned are rapidly frozen, and thus condensed, embrittled, stripped, and at the same time removed with the airflow. It will not cause any harm to the surface of the object to be cleaned, especially the metal surface, and will not affect the finish of the metal surface.
