Abstract
An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous COcomposite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between COand additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), COparticles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged COparticles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical COparticle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.
