Dry-ice cleaning is a form of abrasive blasting, in which compressed air is used to blast dry-ice pellets on the target surface to remove contaminant.
Upon impact on the surface of the cleaning target such as a mold or die, the dry-ice pellets almost immediately sublimate (or gasify), leaving no blast media or solvent, which is usually left by other blast cleaning methods. It is a clean system without the need for recovery or aftertreatment of residue.
The dry-ice pellets used in this cleaning method are quite soft, producing minimal abrasion on the target surface. The impact of high-speed pellets crushes dirt or contaminant on the target surface.
The -79℃ dry-ice pellets almost instantly change from a solid to a gas upon impact on the target surface. The sublimation process expands the volume of dry ice almost explosively by 750 times, peeling dirt or contaminant off the target surface.
Soft dry-ice pellets produce minimal abrasion and clean the surface of base material.
Dry-ice pellets almost immediately sublimate upon impact on the surface of the base material, leaving no residue blast media. The costs for waste disposal or recovery after cleaning are eliminated.
