Kuivajääpuhallusta

Kuivajääpuhallus, also known as dry ice blasting, is a cleaning method that utilizes frozen carbon dioxide pellets as the abrasive medium. The process involves propelling these pellets at high speed using compressed air. When the dry ice pellets strike the surface to be cleaned, they undergo a rapid sublimation, transitioning directly from a solid to a gas. This sublimation process creates a small expansion of volume and a significant drop in temperature on the surface, which helps to dislodge contaminants. The primary cleaning action comes from the kinetic energy of the pellets and the thermal shock caused by the extreme cold. Unlike traditional abrasive blasting methods, dry ice blasting is non-abrasive to most surfaces and leaves no secondary waste product, as the carbon dioxide simply evaporates into the atmosphere. This makes it an environmentally friendly option. It is effective at removing a variety of substances including grease, oil, paint, carbon deposits, and mold. Common applications include industrial cleaning of machinery, food processing equipment, molds, and historical artifact restoration. The equipment used typically consists of a dry ice blasting machine, a compressor, and a hose with a nozzle.
