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.
During this method, the ice pellets are propelled at a high speed towards the surface that is being cleaned. Once the pellets collide with the surface, they sublime thus transferring the energy to the surface. This produces minimal abrasion. During sublimation, a lot of heat from the surface is absorbed that eventually produces shear stress due to heat shock.
The rate of thermal conductivity between the surface and the contaminant is a factor which this method relies on. It makes the process more efficient. The process of converting a substance from a solid state directly to a gaseous state is what happens during sublimation. The sublimation enables the elimination of the contaminant by creating shock waves. The less important wastes are produced by water blasting but not dry ice cleaning.
The pellets used can be acquired in two ways, that is, solid pellets and ice shaved from ice blocks. The used of shaved ice usually generates ice, which reduces its efficiency in comparison to the use of solid pellets. Also, the inconsistent production of ice makes it less effective. Thermal kinetic effect, pellet kinetic energy and thermal shock effect are the major factors which facilitates the process.
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.
The carbon dioxide cleaning is essential for cleaning a variety of surfaces such as food processing equipment. Here, it is used to remove microorganisms such as Salmonella enteretidis, E.coli and listeria from surfaces. When removed properly, this method removes microorganisms completely. Another attribute that makes dry ice cleaning an ideal method is its ability to clean equipment without producing a fire or electrical accident.
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.
Another factor that should be considered is the position of the exhaust vents in the room where dry ice cleaning occurs. Normally the exhaust vents should be placed at the bottom area of the room. This is important since carbon dioxide is denser than air.
