Dana-Ridge has introduced Vaqua mercury model high volume, low pressure wet blasting system.
If there is a problem of descaling, degreasing, decarbonising, de-rusting, general component cleaning, surface preparation prior to painting, coating, plating or bonding or the need for a final quality finish.
The user may require radioactive decontamination; fine deburring or peening to increase component life by stress relieving. The Vaqua Mercury wet blasting machine can solve these problems without component damage and without harming the environment.
The present method is probably the use of one or more of the following;
- Strong effluent forming environmentally hazardous chemical(s)
- Laborious handwork
- Dusty damaging shot or sand blasting
The principle of the system is the bombardment of high volume, low pressure, recirculating flow of 25% to 30% solid particles in water.
The chosen solid media does the work, but there is always a cushion of water between the component surface and media particles. This prevents impregnation, damage and the excessive breakdown of media.
The advantages of Vaqua processing are:
- Complete control of blast processing, mild to aggressive, sateen to matte finish and everything in between
- Versatility - a wide range of finishes with one size and type of media. Although a variety of different media types can be used in the machine i.e.
- Glass bead, aluminium oxide, plastic, sodium bicarbonate and others to suit the particular processing application
- Simultaneous removal of oil, grease, burnt on carbon, paint, scale, soil material or surface contaminant. No pre-cleaning needed
- Environmentally friendly - No toxic or harmful chemicals used and no atmospheric pollution generated
- Complete elimination of dust, does not need dry air
- No component erosion or impregnation, critical measurements maintained
- Good economics, low media consumption, low maintenance costs and low power consumption vs. speed of processing
