Sodium bicarbonate has become a popular choice for air blasting when contaminant removal is necessary yet it is critical that the surface of the substrate not be etched or abraded.
Sodium bicarbonate blasting can be accomplished in either open air blasting or in a blast cabinet. The equipment required for sodium bicarbonate blasting is engineered specifically for this blast media. Sodium bicarbonate, or baking soda, absorbs moisture so it is critical that the air supply be clean dry air. The blast pot and dust collectors used in these applications are designed specifically to deliver a consistent and adjustable stream of sodium bicarb.
Sodium bicarbonate is a one pass media, meaning it cannot be recycled. This is due to the fact that it is so soft that it is pulverized on its’ first impact and becomes dust after hitting the surface to be cleaned. You can also blast parts that have a film of oil, grease or moisture with sodium bicarb.
