CO2 Cleaning

Jamko specializes in cleaning solutions that other blasting service companies simply cannot. We utilize innovative cleaning solutions utilizing dry ice blasting systems -- a completely environmentally safe and non-abrasive method for industrial cleaning, stripping, preparing surfaces for re-coating, sanitizing, and decontaminating using a high density dry ice pellet.

Although it is often compared to bead blasting, sand blasting, or soda blasting, dry ice cleans differently. Traditional abrasive blasting methods clean by abrading the substrate or removing a portion of the surface being cleaned. Dry ice, on the other hand, cleans by breaking through contamination and lifting it off while usually leaving the surface unaffected.

Process

Step #1 - Energy Transfer - With dry ice blasting, dry ice pellets are propelled out of the blasting gun at supersonic speed and impact the surface. The energy transfer knocks off the contaminant without abrasion. The force of this impact is the primary means of cleaning.

Step #2 - Micro-Thermal Shock - The cold temperature during dry ice blasting of the dry ice pellets hitting the contaminant creates a micro-thermal shock (caused by the dry ice temperature of -79º C) between the surface contaminant and the substrate. Cracking and delaminating of the contaminant occurs furthering the elimination process.

Step #3 - Gas Pressure - The final phase of dry ice blasting has the dry ice pellet explode on impact, and as the pellet warms it converts to a harmless CO2 gas which expands rapidly underneath the contaminant surface. This forces off the contaminant from behind. The contaminant is then relocated, typically falling to the ground. Since the dry ice evaporates, only the contaminant is left for disposal.
