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.
When using this method, dry ice pellets are propelled on the surface at a high velocity. There is minimum abrasion happening to the surface when the pellets come in contact with it ta high speed. In comparison to other blasting materials such as sand, dry ice pellets are quite soft. Sublimation of the pellets happens upon impact when heat is generated.
Shear stress occurs when a lot of heat is absorbed during sublimation process. The application of stress improves the level of cleaning. There is less heat on the top than the underlying surface. This causes easily flaking in the film of dirt on top. This therefore leaves the surface clean. The surface needs to have good thermal conductivity in order to get effective results.
The procedures used in dry ice blasting are mainly single-hose and two-hose blasting. The two-horse method involves the use of different hose pipes to deliver the compressed air and the dry ice pellets. They are sucked by the use of the scheme effect. On the other hand the single-hose blasting entails the use of only one hose pipe in the delivery of the compressed air and the pellets. This type is more efficient as compared to the two-hose procedure.
The single-hose systems provide more aggressive cleaning hence they can clean up heavier dirt layers and faster cleaning. They can also use longer hose compared to the two hose without a drop in the pressure at any point. Single-hose has a feature that enables them to make use of a quickly cycling air lock. This helps in prevention of potential dangers associated with the blasting.
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.
When performing this process, it is vital for one to consider safety. Whenever the process occurs in a place that is poorly ventilated, carbon dioxide concentration can become life threatening. Chocking and death can result. Proper ventilation is required together with proper gear to prevent noise.
