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 1):
An apparatus for producing an electrostatically charged and homogeneous CO2 composite spray containing an additive for use on a substrate surface comprising:\n a. multiple nozzle electrodes positioned axis symmetrically about an additive injection nozzle; b. said nozzle electrodes comprising 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; c. said at least three through ports forming three landing guides for centering and positioning an adjustable expansion tube assembly; d. the adjustable expansion tube assembly comprises a first capillary within a second capillary; e. the first and the second capillaries are adjustable within the center through hole; f. the additive injection nozzle comprising a through ported and grounded additive injection nozzle body containing an additive delivery tube, and the grounded additive injection nozzle body flows air to form an air-additive aerosol; 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 electrodes, and the CO2 particles then mix with air to form air-CO2 aerosol; the electrostatically charged nozzle electrodes and the air-CO2 aerosol passively charge the air-additive aerosol; the air-additive aerosol and the air-CO2 aerosol combine away from the nozzles to form the electrostatically charged air-additive-CO2 aerosol, which is projected at the substrate surface, whereby the CO2 particles and the additive interact to form the electrostatically charged and homogeneous CO2 composite spray containing an additive mixture in the space between the nozzles and the substrate surface; and the electrostatically charged and homogeneous CO2 composite spray containing an additive is projected at the substrate surface.
