What is Abrasive Blasting?
Abrasive blasting, Sandblasting, bead blasting, shot blasting… are they all the same? The quick response is yes! For decades the term “sandblasting” was used by everyone, as it was the most used choice of material when blasting. However, today with advancements in blasting technologies and increased awareness of health risks, sand is NOT recommended.
The simple idea to explain abrasive blasting, is when a combination of high pressure compressed air and a fine or crushed abrasive material is forced out of a powered nozzle. The forceful contact of the abrasive particles effectively remove rust, paint, dirt and other types of corrosion. There are many abrasive material options that are suitable based on certain requirements, constraints and the type of substrates.
What is the Right Abrasive Material to Use?
This will depend on the project and results required. When evaluating each type of abrasive material the following come in to play:
