Dry ice blasting: cleaning without chemicals
Dry ice blasting can be compared to sandblasting, high-pressure water, or steam blasting, but gives better results because it leaves no residue. Dry ice is made up of frozen Carbon Dioxide (CO2) pellets. Dry ice blasting uses a process called sublimation to clean surfaces. Tiny dry ice pellets are accelerated in a pressurised air stream and directed towards the surface that needs to be cleaned. The key to its success is that dry ice penetrates through the waste, cools it, and removes it without damaging the underlying surface.
Dry ice blasting has many advantages:
- Non-abrasive so doesn’t damage the equipment being cleaned
- Non-toxic so can be used in the food industry
- Non conducive so is safe to use on electric motors
- Fast and thorough and can clean very small spaces
- Does not require the use of chemicals so is environmentally friendly
- Requires less downtime
A further advantage of dry ice blasting is that surfaces that have been cleaned by dry ice blasting do not require any further cleaning and are immediately available for use thereby improving productivity, saving time, and reducing costs.
Dry ice blasting can be used to clean surfaces from:
- Oil and Grease
- Stickers and stubborn adhesives
- Soot, char and smoke damage
- Welding splatter
It is effectively used in many industries from the mining sector, car manufacturing, right through to the pharmaceutical industry.
Dry ice blasting is very noisy and the Carbon Dioxide that is released during the blasting can be harmful if the space is not properly ventilated. Hire a professional like Polmax to help you.Tip: dry ice blasting can be effectively used even on graffiti
