This is a method of abrasive blasting that utilizes carbon dioxide to clean a surface. Dry ice is a form of carbon dioxide that is solidified. The process is accelerated in a pressurized air stream using a pump that is directed in to a surface that needs cleaning. It is a safe and environmentally friendly method since it does not contain any chemicals that can be harmful to the persons doing the process. Today, many businesses offer Dry Ice Blasting Services.
This method involves propelling the dry ice pellets at extremely high velocity on to a surface. When the pellets hit the surface they produce minimum abrasion to surfaces. This is because the dry ice pellets are quite soft compared to other blasting materials like sand. The impact causes the generation of heat that result to the sublimation process.
Sublimation is very important as through this, a lot of heat is absorbed and results in shear stress. Shear stress also helps in the cleaning of the surface. This is because there will be more underlying heat than that on the surface, making the dirt to be easily removed. Therefore, this process is best suited for surfaces that are good heat conductors.
There are several methods used namely the two-hose and single-hose dry ice blasting. In the two hose method compressed air and the dry ice pellets are delivered from different hoses. They are both sucked out using the venture effect. In the single-hose method, the air and the dry ice are delivered using a single-hose. The two hose system is less effective compared to the single-hose.
The single-hose procedure is suitable for cleaning heavy layers of dirt as it is faster and more belligerent. Here the hose to be used can be longer as compared to the two-hose type without the incidences of decrease in pressure. This procedure is unique as it has a quick cycling air lock. The air lock is vital in the prevention of risks that come with the blasting process.
Decontaminating of surfaces and cleaning of food processing equipment can be done using this method. Microorganisms found on decontaminated surfaces that are undetectable through simple conventional methods can be detected by using dry ice method. Fire related hazards cannot be caused when cleaning the surface hence the method is said to be safe. Different kinds of solvent-based cleaning products can use this method. Aero industries use this method to clean surfaces. One of the reasons this method is preferred is because it does not leave residues.
Dry ice blasting uses a combination of forces that enables a surface to be cleaned without any damage. It does not leave any residue since it utilizes the sublimation principle hence no harmful secondary waste is left behind.
Safety is important when carrying out the procedure. The carbon dioxide in the dry ice can easily displace the oxygen in the air if the procedure is done in a place with poor ventilation. This can lead to choking and finally death. Hence the room should be properly ventilated. One should also wear proper gear to protect themselves from noise.
