Wet Abrasive Blasting
Also called vapormatting, wet abrasive blasting involves using a wet process to take extremely fine or coarse materials and using hot water and soap to allow for degreasing and blasting. The idea is to eliminate dust and/or things like hazardous material or waste and to do so without danger. Examples include removing asbestos or radioactive components. Things that might need wet abrasive blasting include kitchen cabinets and commercial dishwashing machines.
Bead blasting, also called glass blasting, is "the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface." This process is used to clean calcium out of pools, for example, and is designed to remove entangled fungus and brighten the color. The process of bead blasting is also used to remove paint.
Automated blasting refers to the automation of abrasive blasting.
Dry Ice Blasting
Dry ice blasting is the process of pressurizing air and dry ice; the material is meant to be cleaned without ruining the properties of it. The dry ice modifies to leave no after-residue for clean up.
Hydro blasting, as you guessed it, is the utility of using highly pressurized water to remove things such as buildup or old paint.
As the name suggests, a wheel is used to blast and propel the abrasive against the object being changed. No gas or liquid is used in wheel blasting.
This blasting process uses small nozzles to run a stream of abrasive to a small and very specific area, position or part on a larger part or area.
