Glass, timber, brick, metal, paint and other surfaces can be cleaned using dry ice blasting.
The process of dry ice blasting is similar to sand or soda-blasting services. By accelerating the dry-ice media towards the soot effected surface, a controlled pressurised stream is used. As it is applied towards the surface, contaminate is dislodged from the affected area which cleans the surface back to its pre-damaged condition.
How it Works
When using dry ice, the temperature is around minus 80 degrees Celsius. Due to the differences in the temperature between the dry ice used, the normal atmospheric temperatures and the difference in temperature in the surface being blasted, a thermal shock occurs, which causes the breakdown of the bond of the contaminant to the surface being cleaned, forcing it to dislodge.
Upon coming into contacting with the surface, and dislodging the material, the dry ice completely evaporates – ice is soft enough so that it will not damage the surface.
Dry Ice Advantages
Dry ice is non-conductive, non-flammable and non-abrasive and uses water or chemicals. It is Eco-friendly and has no secondary contaminants that can harm, like grit and solvents used in other cleaning methods.
After the cleaning performance, the ice evaporates and melts away. This means there is no additional clean-up work to remove the ice and excess water.
Types of Use
It is a portable system and is suitable in an indoor as well as an outdoor setting.
You can use it for soot or smoke damage or for mould re-mediation jobs to complete.
Ice is soft, so it will not damage the carrier surface; this means that any surface; like timber, glass, tile, plastic, steel, and other surfaces, can all be cleaned with this dry ice method of blast cleaning.
