What is Abrasive Blasting and how can it help your business?
Abrasive blasting or commonly known as “Sandblasting” is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface coatings.
Dry abrasive blasting commonly known as ” Dry sandblasting” or “Dry Blast” is the operation of forcibly propelling a stream of dry abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface coatings. Dry abrasives are commonly garnet based.
Wet abrasive blasting commonly known as ” Wet abrasive sandblasting”, or “Slurry Blasting” or “wet slurry blasting” is the operation of forcibly propelling a stream of wet abrasive material , a “slurry” mix, commonly garnet based with the addition of low amounts of water, against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface coatings.
Common features include: the ability to use extremely fine or coarse abrasive media, the ability to use environmentally beneficial minimal quantities of water, and the elimination of dust. Hazardous material or waste can be removed without danger – e.g. removal of lead paint or asbestos coverings, or other contaminants from structures, leading to effective decontamination.
What’s is the benefit of Wet Abrasive blasting?
Surface removal speeds can be as fast as conventional dry sand blasting when using the equivalent size and type of media. However the presence of water between the media and the substrate being processed creates a lubricating cushion that can protect both the media and the surface from excess damage. This has the dual advantage of lowering media breakdown rates and preventing impregnation of foreign materials into the surface.
- Hence surfaces after wet blasting are extremely clean, there is no embedded secondary contamination from the media or from previous blasting processes, and there is no static cling of dust to the blasted surface. Subsequent coating or bonding operations are always better after wet blasting than dry blasting because of the cleanliness levels achieved.
The benefits of Wet Abrasive blasting:
- minimal dust, as the water reduces dust levels
- minimal water usage, as the water is used as a minimal abrasive coating , not as the abrasive itself
- surfaces are left clean – ready for application of coatings
The SRS System differences- A variable Low pressure Wet abrasive blasting system with low abrasive and low water consumption
The SRS Wet Abrasive blasting system is a variable input low pressure wet abrasive blasting system with low abrasive consumption and low water consumption. Our technology :
- Mobile units – multiple Trailer based Compressor Units from 172 CFM to 185 CFM
- Variable pressure from 25 psi to 110 psi dependant on the surface and substrate requirements
- Variable media – 5 different grades of media / blasting aggregate used dependant on the surface and substrate requirements
- Variable water to achieve optimal results
The extra benefits of the SRS Low pressure Wet Abrasive blasting system:
- Low compressor pressure , variable from 25 psi to 110 psi allow greater control of blast
- Low water consumption, approximately 14 litres/ hour , reduces water damage to surrounding site
- Low particulate (abrasive) usage, reduces abrasive materials costs and clean up time
Remember the surfaces cleaned by the SRS System are immediately ready for protective coating application, there is no downtime, no waiting for the surfaces to be cleaned; protective coating application can start immediately.
Protective coating application, now PCCP Accredited Class 3,4
SRS is an Accredited Industrial Paint Applicator (PCCP Class 3,4). Where you require protective coating application, our teams are trained and experienced in the application of protective coatings in industrial situ. We apply industrial protective coatings to the manufacturer’s specification to ensure warranty requirements are met.
