ABSTRACT:
The invention relates to a spray system for a multi-ingredient ablative material wherein a nozzle A is utilized for suppressing overspray. The nozzle includes a cylindrical inlet (12) which converges at (12a) to a restricted throat (13). A curved juncture (15) between cylidrical inlet (12) and convergent portion (12c) having a predetermined radius of curvature affords unrestricted and uninterrupted flow of the ablative material. A divergent bell-shaped chamber (14) and adjustable nozzle exit B is utilized which provides a highly effective spray pattern in suppressing overspray to an acceptable level and producing a homogeneous jet of material that adheres well to the substrate.
