Abstract:
An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO 2  composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO 2  and 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), CO 2  particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO 2  particles 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 CO 2  particle-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.

Claim (Index 10):
A nozzle electrode apparatus for producing an electrostatic field comprising:\n a. an elongated body with a nozzle tip with a center through hole, and arising from the center through hole are at least three axisymmetric through ports; b. said at least three through ports forming three landing guides for positioning an adjustable expansion tube assembly; c. the adjustable expansion tube assembly comprises a first capillary within a second capillary; d. the first and the second capillaries are adjustable in position within the through ported center hole; and e. whereby CO2 particles are flowed through the adjustable expansion tube assembly to create an electrostatic charge, which is shunted to the three landing guides to electrostatically charge the nozzle electrode.
