Abstract
A slurry blasting process employing a liquid carrier medium such as water contains a dispersed water-soluble particulate abrasive to enhance blast cleaning efficiency. Slurry blasting is performed at liquid pressures below 500 psi with an air to slurry mass ratio of generally at least about 0.05. The slurry can be recovered and continuously reused.
Claims23
A process for blast cleaning comprising:
- subjecting a work surface to a blast stream comprising a slurry of a carrier liquid and a particulate abrasive material, and a pressurized air stream to atomize the slurry, the process further comprising maintaining an air to slurry mass ratio of generally at least about 0.05.
