WHAT IS DRY ICE BLASTING?
Dry ice blasting is a revolutionary blasting method that uses
small, compact dry ice pellets as the blasting material. The
dry ice pellets are accelerated in a jet of compressed air similar
to that used in traditional blasting methods.
Dry ice blasting is designed to replace high-pressure hosing
and other traditional blasting methods that use materials such
as sand, glass and plastic as abrasive agents. However, additionally
a wide range of other cleaning methods that involve the use
of hazardous chemicals, solvents, etc., can with great advantage
be replaced by dry ice blasting.
The unique feature of dry ice as a blasting material is that
it vaporises on contact with the surface to be cleaned. Treated
surfaces are therefore left dry and clean, without residues
of detergents or blasting materials. As the process is completely
dry and non-conductive, dry ice blasting can be used where other
methods are unsuitable. For example, electric motors and equipment
with electric, pneumatic or hydraulic components can be cleaned
directly using dry ice blasting.
The system produces no waste products. Only the coating that
has been removed remains to be disposed of, and this can usually
be swept or vacuumed from the floor beneath the treated object.
Dry ice blasting is ideal for removing coatings such as adhesives,
varnish, oil, grease, coal dust, soot, mould release agents
and bitumen - to name but a few of the materials we remove daily
using the process. Dry ice blasting will often allow a company's
production equipment to be cleaned while in operation without
the need for dismantling and costly downtime.
Dry ice blasting is non-abrasive, and surfaces are therefore
treated gently. The system can thus be used on easily-damaged
surfaces like nickel, chromium and soft aluminium.
The process is dry, and no waste materials are produced. This
means that cleaning can be carried out even during short production
shutdowns.
