Dry ice blasting or carbon dioxide cleaning refer to the process of using dry ice to clean a surface. In this technique, solid ice or carbon dioxide is accelerated in an air stream and then directed to the surface that is to be cleaned. Dry ice blasting acts in the same way as other methods such as sand, soda, and plastic bead blasting. The main advantage of carbon dioxide cleaning is that it does not leave any chemical residue behind, making it an environmentally friendly method. This is the process that dry ice blasting services engage in.
When using this technique, high-speed ice pellets are propelled towards the surface to be cleaned. Upon collision with the surface, the pellets transfer their energy to the surface by subliming. The result of this action is production of minimal abrasion. When the pellets sublime they absorb a huge amount of energy form the surface hence producing shear stress from the resulting heat shock.
The effectiveness of this process depends largely on the rate of thermal conductivity between the substrate and the contaminant. Normally, sublimation involves the conversion of the ice form solid to gas. This conversion creates shock waves that facilitate the removal of the contaminant. Dry ice cleaning is advantageous as it does not produce any secondary wastes like media or water blasting.
There are two forms in which one can use this method. These include the solid pellet form and shaving the ice from a block. The shaved ice block method is not reliable as is it produces ice, which is less effective as compared to the solid pellets. There are three primary factors that facilitate the process of dry ice blasting. They include thermal shock effect, thermal kinetic effect, and pellet kinetic energy.
Basically, this method is an improved version of abrasive blasting. The major difference between the two is how they are handled. Abrasive blasting machines and dry ice blasting machines are handled very differently. Dry ice unlike other media is utilized at its temperature of sublimation. As a result, there is the risk of building up a dry ice bomb in the pressurization system.
A variety of surfaces like food processing equipment can be done using this abrasive method. The carbon dioxide cleaning method is capable of eradicating contaminants which form on surfaces. It can removed microorganisms such as listeria, E. Coli, and salmonella enterids among others. The ability of dry ice to clean some equipment without the production of fire or any other accident makes it to be the best option.
Proper ventilation is recommended while using the machine. Carbon dioxide is toxic and can cause death if good measures are not taken. Carbon dioxide normally accumulates in the body and reduces the efficiency with which the body absorbs oxygen. When oxygen deficiency prolongs, biological processes in the body are affected and this can lead to serious health problems.
The position of the exhaust vents in a room where the cleaning is occurring must also be considered. The best position of these vents is the bottom of the room. This is the idea for these apparatus considering that air is lighter than carbon dioxide.
