Types of Blasting
1. Abrasive blasting
?vombines a pressurized stream of air with an abrasive, which is propelled onto the surface of steel to remove paint, rust, and contaminants.
?Abrasive blasting can also be used on concrete to remove discoloration and other marks, and on brick and masonry to clean it.
?Dry abrasives used in surface prep include sand, sand substitutes, coal slag, steel grit and garnet.
?Dry abrasives are sometimes combined with a sponge media to reduce dust at the site of the blast, and sponge is recyclable.
2. Vacuum blasting systems
?capture and collect the blast media;
3. Water blasting
?uses water with abrasive, reducing dust;
4. Bristle blasting
?Aand-held power tool that removes contaminants and creates a surface profile using wire belts , typically used for small areas.
5. Shot blasting
?typically used on concrete to remove existing coatings, and dirt;
6. High pressure water blasting
?water only, at high pressure to clean surfaces and create a profile.
