Below we have put together a number of videos which illustrate the practical applications of dry ice blasting.
ENVIRONMENTAL – CHEWING-GUM REMOVAL
The video shows the removal of chewing gum from floors. In this case, the floor is in marble, which is not damaged in any way. The dry ice used has a diameter of 3 mm and is applied at a working pressure of 3 bar.
CONSTRUCTION – RECOVERY OF A HARDWOOD CEILING
Renovation to restore period buildings to their former beauty is currently a matter of great interest. There is a constant search for non-aggressive equipment and methods which allow the restoration of old buildings ruined by the passing of time to their former glory. Dry ice blasting carried out with DRY GUN and MOBIL UNIT is undoubtedly one of these. It is in fact possible to clean surfaces, returning them to their original splendour, without the use of sand, abrasives in general, water, detergents and/or solvents, thus avoiding aggressive methods and without producing environmentally-harmful residues. The films below show the recovery of a wooden ceiling, with the removal of the old paintwork, returning the wood to its original splendour and exalting the natural grain. The videos show the various stages of the operation carried out with our DRY GUN 02 system and the use of specially-produced 1.7 mm dry ice, which is the most suitable size for the treatment of wood.
FOUNDING – REMOVAL OF RELEASING AGENTS
The video shows the removal of releasing agents from a mould in an aluminium foundry. Dry ice blasting is carried out with our DRY GUN 01 system and with the small P06 gun which permits operations even in tight spaces. Ice consumption is 45 kg/hour at a pressure of 4 bar.
INDUSTRIAL – REMOVAL OF LABELS
The three videos show the removal of labels and glue residue. Dry ice blasting cleans without abrasion, without damaging the surface and without polluting, avoiding all forms of chemical aggression.
INDUSTRIAL – REMOVAL OF RESIDUE FROM GLUE ROLLERS
The video shows the dry ice blasting of an industrial system for the spreading of a dry adhesive. The blasting system used is the MOBIL UNIT 02 which has an hourly consumption of 70 kg of dry ice and a working pressure of 10 atm.
INDUSTRIAL – PAINT REMOVAL
The video shows how a printing plant covered in various layers of paint can be dry ice blasted without damaging the support. Dry ice blasting is carried out with the DRY GUN 02 at a pressure of 6 atm, and an ice consumption of approximately 40 kg/hour
The two videos show the removal of releasing agents from upper moulds for various types of shoe. The speed and quality of the removal process are clear. The ice used is of a diameter of 3 mm, with a working pressure of 4 bar.
The videos demonstrate the effectiveness of dry ice blasting on a system for the production of paper for newspapers. Cleaning is carried out on rollers inside the system, on the conveyor belts and on the roller in the final section of the system. Dirt is removed with dry ice blasting, which avoids the use of water, detergents or solvents, as well as any kind of brush, scraper or abrasive.
The video shows the dry ice blasting of a number of sections of a continuous painting oven for iron pipes. The use of dry ice blasting has completely substituted manual cleaning, significantly reducing the time necessary for maintenance.
The first video shows the removal of antifouling paint from a fibreglass hull. The operation is rapid and does not affect the gelcoat. The quantity of dry ice used is 40 kg/hour at a pressure of 6 atm. The second video shows the removal of lime scale and various incrustations from a propeller. The quantity of ice used is 45 kg/hour at a pressure of 7.5 atm. The third video shows the precision removal of deteriorated fibreglass. Removal is carried out solely on the areas where water has penetrated into the layers of fibreglass. The quantity of ice used is 75 kg/hour at a pressure of 10 atm.
PET PRE-FORM PRODUCTION INDUSTRY
The 3 videos demonstrate how the removal of residue takes place easily, completely and efficiently, even in the hardest to reach areas, without having to intervene either mechanically or chemically.
The video shows the removal of releasing agent from a rotomould. The removal of the releasing agent, which following numerous mouldings is partially blended with plastic, takes place solely with dry ice, without the use of abrasives, and offers the possibility of operating directly inside the machine without damaging the support and without polluting, avoiding all forms of chemical aggression.
The video shows the effects of dry ice on denim. The fact that it is no longer possible to use sandblasting for the finishing of completed items has led to the use of dry ice, which – with the use of specially-studied machinery and nozzles – provides excellent results at reasonable prices.
The video shows the production of dry ice. Liquid CO2 is compressed and extruded via a mould, forming pellets of a diameter of either 1,7 mm, 2.2 mm, 3 mm, 4 mm or 5 mm.
