hand held concrete wiping equipment

Improved Technology

coating removal tool that includes a 12.7-cm (5-in.) diamond grinding wheel and vacuum port for dust extraction, suitable for flat (or slightly curved) walls and floors. The unit is designed with aerodynamic internal and external air intakes, to be used with a vacuum filtration unit vacuum port) for dust-free operations. The LD 1509 FR is rated at 11 amps / 10,000 rpm and weighs only 6 lbs. Depth of grinding is related to stay time and number of passes at any given location.
Baseline Technology
The baseline demonstration was conducted on October 7, 1997 through November 3, 1997, on the interior C Reactor Sample Rooms A and B. Both sample rooms required 1.5 to 3 mm (1/16 in. - 1/8 in.) concrete removal from floors and walls (and for small areas to 6 mm (1/4 in.)). The floors of both sample rooms were painted with lead-based paint. The baseline hand-held decontamination tools demonstrated were a pneumatic scaler and single-piston scabbler, connected to a HEPA vacuum filtration system.

The scaler is designed to remove concrete surfaces between 1.5 to 3 mm (1/16 in. and 1/8 in.) depths. It contains a flapper device used to strike concrete surfaces. This tool is also useful in hard-to-reach horizontal areas, such as under equipment. The scaler has a port for connecting to vacuum filtration system. The other pneumatic baseline tool demonstrated was a scabbler designed to remove concrete surfaces between 3 to 6 mm (1/8 in. to 1/4 in.) depths. A single-piston scabbler can reach medium-congested areas and next to walls/floor intersections. The scabbler uses vacuum exhaust for low-dust operations (suction at striking point).
