Clean Better With Cold - See How
Dry ice Blasting. Clean better with cold.
Get deep, cleaning with cold, using dry ice blasting.
Dry ice blasting uses small pieces of dry ice the size of rice that “explode” against the contaminant, causing it to shrink and lose its adhesion. Dry ice is very cold -109°F or -78°C.
The dry ice pieces shoot out of a jet nozzle with compressed air. The nozzle’s unique shape can cause the particles to accelerate faster than the speed of sound before hitting the surface to be cleaned. (see energies-12-04787 for analysis)
Other systems shave a dry ice block for softer blast cleaning material.
The dry ice is softer than sand or glass beads, so it does not spoil the substrata. It works like sandblasting or high-pressure water or steam blasting, but with different results – often better.
The combination of kinetic, thermal, and sublimation energy produces unparalleled results. The super cold temperature of the dry ice blasting against the material to be removed causes it to shrink and lose adhesion from its subsurface. Additionally, some dry ice penetrates through the contaminated material and contacts the warmer original surface, causing the dry ice to turn into a gas, expanding under the harmful material and speeding its removal.
Rust, paint, oil, grease, asphalt, tar, decals, soot, dirt, ink, resins, jet exhaust tars, and adhesives are materials removed by this procedure. Only the removed material must be disposed of, as the dry ice sublimes into the atmosphere.
Dry ice blasting does not create secondary waste or chemical residues and is
