Cleaning using Dry Ice Blasting!
Are
your machines covered with layers of dirt, oil, glue and grease?
Sounds like a big job to clean but it's not!
Have
you ever considered cleaning your machines and equipment with
Dry Ice Blasting?
How
Dry Ice Blasting Works (CO2 cleaning or cryogenic cleaning)
Dry
ice blasting uses compressed air to accelerate solid carbon dioxide
(CO2) dry ice pellets to literally strip industrial equipment
surfaces of a multitude of residues, including ink, glue, paint,
food, rubber, mold release agents, dirt, grease, oil, and numerous
other contaminants.
Dry
ice blasting is similar in principle to sand blasting. Instead
of sand, dry ice blasting uses high-density dry ice pellets,
which are propelled onto a surface using compressed air.
Unlike
sand blasting, dry ice blasting is non-abrasive. When dry
ice pellets hit a surface, such as a metal part contaminated with
oil and grime, the dry ice pellets immediately sublimate [change
in form from solid to gas].
The
rapid expansion of the solid dry ice into gas causes a tiny "explosion"
which loosens the contaminant, in this case, the oil and grime.
The extremely cold temperature of -109 degrees Fahrenheit of the
dry ice causes the bond of the contaminant to the metal part to
weaken. This loosens the contaminant, freezes it in the process,
and causes it to release from the metal part.
Dry
ice blast cleaning leaves no residue and leaves no toxic waste
as solvents can. It lets you skip clean-up problems
associated with other cleaning methods. Dry ice blasting also
meets EPA, USDA, and FDA guidelines.
