soda blasting

[David Bienvenu]

George,
I'm familuar with 2 different processes.

One is with regular sand blast equipment and soda beads used as a media. I have also saw soda beads attached to plastic (Looked like small fly bait). It is used around here to sand blast diesel engines that have been offshore in the oil field.

The second is used with a waterblaster. The soda solution is in a drum, has a hi-pressure injector pump that injects the media into the water stream. I watched this being done to an aluminum hull house boat barge at a local dry dock. It really worked well. The whole rental set up was on a trailer that could be towed with a P/U and rented by the day. They also load as many drums of media as needed on the trailer and you just swap the injector pump.
