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. In addition, however, a wide range of other cleaning methods that involve the use of hazardous chemicals, solvents, etc., can with 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 direct 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.
Fast and Effective Cleaning:
Dry ice blasting systems have extremely high cleaning speeds, and even normally inaccessible parts can be rapidly cleaned using the wide range of nozzles available. Blasting material residues do not become trapped in every nook and cranny, and no detergent or blasting material is left on chains and drives.
Dry ice blasting is ideal for cleaning machinery, electrical installations, electro-mechanical equipment, surfaces and moulds.
Reduced Equipment Wear and Tear:
Dry ice blasting is non-abrasive. Surfaces are therefore treated very gently, and wear and tear resulting from the use of steel brushes, scrapers and the like is avoided.
Reduced Downtime:
A machine can often be cleaned by dry ice blasting while in operation, thus eliminating the need for dismantling and subsequent re-assembly. This is of considerable economic importance as downtime can be eliminated or drastically reduced.
No Waste Disposal Costs:
Costs connected with the disposal of hazardous chemicals or solvents are saved because dry ice vaporises on contact with the surface being treated. Only the dislodged coating material must be removed from beneath the treated object.
