Dry ice blasting is a cleaning method that uses dry ice, which is solid carbon dioxide (CO2), as the blasting medium. It involves propelling small pellets of dry ice at high speeds to remove unwanted contaminants from various surfaces. The process works by using compressed air to accelerate the pellets of dry ice, creating a powerful blasting effect. When the dry ice particles come into contact with the surface being cleaned, they rapidly convert from a solid to a gas in a process called sublimation.
This causes the contaminants on the surface to be dislodged and removed. Dry ice blasting is a non-abrasive and non-conductive method, making it suitable for use on a wide range of materials and surfaces, including metal, plastic, wood, and even electrical equipment. It is commonly used for cleaning applications in industries such as automotive, manufacturing, food processing, and fire restoration. Some benefits of dry ice blasting include its ability to clean without leaving residue, its non-toxic nature, and its environmental friendliness. Since dry ice sublimates into the atmosphere, it does not produce any secondary waste, making it a more sustainable cleaning option compared to traditional methods that use chemicals or solvents.
