Definition - What does Sponge Jetting mean?
Sponge jetting is a blast cleaning method that uses miniature sponge particles as an abrasive medium. Like other blast cleaning technologies, sponge jetting cleans the surface of the substrate by removing paint, dirt, grease and other contaminates. Sponge jetting is renowned for its ability to minimize dust. It is, therefore, best suited for environmentally sensitive areas where airborne particles are undesirable.
Corrosionpedia explains Sponge Jetting
While other abrasive cleaning methods like sandblasting are highly effective, they produce copious amounts of dust. Sponge jetting addresses this issue by using miniature sponges to trap any dust that might otherwise escape into the atmosphere.
The sponge particles, which are also impregnated with abrasives, are propelled to the surface using a pressurized feed unit. As the sponge impacts the surface, it flattens to expose the abrasive media that scrubs the surface. When the sponge expands, it creates a vacuum that traps dust and other hazardous materials within the sponge cells. The sponges are then collected and fed through the feed unit for recycling.
