Working Principle When CO2 pellets come into contact with an object, dry ice at cold temperature of -109.3F or -78.5C will explodes on the material surface, from solid to gas in an instant, through the use of kinetic impact, thermal dynamics and gas expansion, CO2 breaks the bond between the contaminant and the substrate, causing the dirt to contract and lose surface adhesion, which makes it a non-abrasive cleaning method.
Using a high pressure spray gun to eject tiny carbon dioxide particles at high speeds compared to other substances used in media cleaning (sand, plastic, etc.), the CO2 particles are relatively soft and the carbon dioxide does not damage the surface even at high speeds and high impact forces.
In this way, it can more environmentally friendly remove the desposit, paint, grease, decal, dirt, oil, ink, resin, and adhesives etc.
