Widely used advanced dry ice cleaning machine for factory cleaning/dry ice clean equipment
Dry ice is solid carbon dioxide at room temperature and 6079.8 kPa pressure, the carbon dioxide becomes colorless liquid condensate, then quickly evaporated at low pressure, it condenses into a block of compacted snow and ice-like solid substance, the temperature was minus 78.5 ℃. This is the dry ice. After it is heated without liquid and direct gasification.
Cleaning with dry ice! This new development is quickly expanding around the world. One system uses small rice size pellets of dry ice shooting them out of a jet nozzle with compressed air. It works somewhat like sandblasting or high-pressure water or steam blasting, with superior results. The frigid temperature of the dry ice -109.3°F or -78.5°C "blasting" against the material to be removed, causes it to shrink and lose adhesion from its sub surface. Additionally when some of of dry ice penetrates through the material to be removed, it comes in contact with the underlying surface. The warmer sub surface causes the dry ice to convert back into carbon dioxide gas. The gas has 800 times greater volume and expands behind the material speeding up its removal. Paint, oil, grease, asphalt, tar, decals, soot, dirt, ink, resins, and adhesives are some of the materials removed by this procedure. Only the removed material must be disposed of, as the dry ice sublimes into the atmosphere.
Dry ice blasting is a cleaning process with three very distinct values. 1). the dry ice (cleaning agent) dissipates upon contact leaving no secondary contamination or discard. 2). It is non-conductive (can be used on "live" electrical components as well as running machinery). 3). It is non-abrasive (cleans circuit boards and most other electrical components).
Ice cleaning is applied to the tire industry, rubber casting, automotive, aerospace, machinery manufacturing, mold industry, printing equipment, oil and chemical industry, breaking the traditional time-consuming wash, cut and other shortcomings, efficient, energy-saving and clean, environmentally friendly online new cleaning mode.
