THE DRY ICE BLASTER TECHNOLOGY

 
 

 

How it works

The dry ice blasting uses small pellets of dry ice sprayed through a jet nozzle with compressed air to remove paints, oil, grease, dirt,ink, adhesives and other materials you want to remove. The frigid temperature of the dry ice against the dirty surface causes adhesion to shrink and loosen from the surface. On immediate impact, the dry ice evaporates into environmentally safe and innocuous CO2 gas.

The kinetic energy ( E = ˝ mv 2)

The energy associated to the mass and to the speed is transferred to the surface to be cleaned / coating removal. This is the fundamental way to work either with this dry ice method or with sand / water etc.

Thermal differential

When the dry ice pellets cold touch the surface, a small thermic difference occurs between the coating material, the contaminant and the substrate. This provokes cracks and the detaching facilitating the removal process.

Micro – Explosion

When the dry ice touches the surface and it transforms into innocuous CO2 gas, , this tends to invade the cracks and the pores penetrating into the coating / contaminant.Then it warms up and it expands rapidly and it makes the coating / contaminant detaching from the substrate, favouring still further the coating removal or the cleaning process.

Sublimation

With an inferior pressure at 5.2 bar, the solid CO2 transforms directly in gaseous state without turning into the Liquid state. But if the blasting pressure is superior at 5.2 bar ( 5.2 x 14.7 = 76.44 psi ),the CO2 in the sublimation state will show some characteristics of the Liquid CO2 while the same reaches its "triple point". Has been proved that the Liquid CO2 is a strong organic solvent so it is reasonable to suppose that this solvent action can be present when the blasting pressure is superior at 5.2 bar.

 

 

BENEFITS OF DRY ICE BLASTING PROCESS

Decreased downtime

Dry ice blasting does not require equipment to be uninstalled or disassembled to clean it. Downtime can now be measured in minutes with the dry ice blaster, not hours or days like with other cleaning methods. This is a –saving cleaning process that uses dry ice pellets and compressed air.

Safe for all equipment

Dry ice is soft enough not to pit the equipment, but is strong enough to clean it. The dry ice pellets evaporate into gas on impact so there is no residue or grit that can cause future damage to the equipment.

Sanitary and clean

Dry ice evaporates on impact leaving no mess to be cleaned up.Only the material being removed must be disposed of.

Environmentally-Friendly

The dry ice pellets evaporate as an environmentally-friendly gas and leaves no harmful wastes.

Dry ice blasting is:

- non-abrasive

- non-flammable

- nonconductive

It does not produce CO2 or add CO2 to the atmosphere and therefore does not contribute to the greenhouse effect.Dry ice blasting is truly, and completely, environmentally friendly!

How Dry Ice Blasting works?

Dry ice blasting uses small pellets of dry ice sprayed through a jet nozzle with compressed air to remove paint, oil, grease, asphalt, tar, decals, soot, dir, ink, resins,adhesives and other materials you want to remove. Instead of using hard abrasive media to grind on a surface (and damage it), dry ice blasting uses soft dry ice,accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable item off the underlying substrate. On the immediate impact, the dry ice evaporates into environmentally safe CO2 gas. Dry ice blasting minimizes waste,saves time and saves money. Enjoy the benefits of a time - saving cleaning process that uses dry ice pellets and compressed air.
