In granular dry ice cleaning medium, by compressed air to dry ice particles in high speed spray to the cleaning surfaces, make clean the dirt on the surface of the frozen to embrittlement and burst, dry ice particles by osmosis knock-on effect between dirt and base material, then sublimation, instantaneous volume increases 800 times, forcing the dirt away from the base material, achieve the purpose of cleaning.
Controlled temperature auxiliary gas, object surface no condensation.
Removal of foreign particles at micro and nano levels.
Micro-nano particles dry ice, small damage.
No waste water, waste liquid generated.
No additional drying process, low power consumption.
Suitable for complex shapes.
Dry ice particles diameter: 0.5 1000 microns is adjustable.
Optional online detection, graphical cleaning and other functions.
