The dry ice blasting machine utilizes compressed air to spray dry ice at high speed onto the surface of the object to be cleaned. Through the impact, temperature differential, and sublimation properties of dry ice, it reduces the adhesion between contaminants and the substrate, thereby achieving the cleaning effect. Dry ice cleaning machines are primarily categorized into three types based on the form of dry ice:
- Dry ice pellet blasting machine, uses high-density dry ice pellets of 3mm as raw material. The dry ice pellets feature strong impact force and high efficiency, suitable for cleaning industrial molds, engine carbon deposits, castings, and large equipment, making them ideal for large-area, rough cleaning applications.
- Dry ice block cleaning machine, also known as dry ice snowflake cleaning machine, uses single 5kg block dry ice as raw material. The dry ice block is cut by blade rotary cutting to form dry ice snowflakes. The impact force of dry ice snowflakes is softer than that of dry ice particles, making them suitable for cleaning precision equipment.
- Liquid CO2 cleaning machine, uses liquid carbon dioxide as raw material, forms micrometer sized dry ice microcrystals at the nozzle, with a softer impact force than dry ice snowflakes. It is mainly used for cleaning precision components such as semiconductors, circuit boards, optical lenses, etc.
Among them, the granular dry ice blasting machine is the most widely used, which is divided into strong, standard, small and mini dry ice cleaning machines. Users should choose the correct dry ice cleaning machine according to their actual working conditions. If there are any questions about the selection, they can check with the professional dry ice cleaning machine supplier Sichuan Aosituo Technology.
