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.
