Abstract
A blast nozzle for accelerating a stream of abrasive particles to a surface for the cleaning thereof has a nozzle body formed of a non-electrically conductive material and is provided with an encapsulating coat to prevent breakage of the nozzle body. To prevent the accumulation of static electric charge during the blast cleaning operation, the exterior surface of the blast nozzle core is covered with an electrically conductive layer disposed between the nozzle body and the encapsulating coat, the nozzle further including an electrically conductive grounding pathway contacting the electrically conductive layer and passing through the encapsulating coat so that the electrically conductive layer can be bonded to ground to provide a pathway for removing the accumulated static charge and prevent periodic sparking.
