摘要:
A method and apparatus is disclosed for kinetic spray coating of substrate surfaces by impingement of air or gas entrained powders of small particles in a range up to at least 106 microns accelerated to supersonic velocity in a spray nozzle. Preferably powders of metals, alloys, polymers and mixtures thereof or with semiconductors or ceramics are entrained in unheated air and passed through an injection tube into a larger flow of heated air for mixing and acceleration through a supersonic nozzle for coating of an article by impingement of the yieldable particles. A preferred apparatus includes a high pressure air supply carrying entrained particles exceeding 50 microns through an injection tube into heated air in a mixing chamber for mixing and acceleration in the nozzle. The mixing chamber is supplied with high pressure heated air through a main air passage having an area ratio relative to the injection tube of at least 80/1.

Disclosed is a nozzle for cold spray and a cold spray apparatus using the same. The nozzle for cold spray includes a hollow-type nozzle section. The nozzle section includes a convergence inlet section (2) in which the cross-sectional area is converging, a throat area (5) connected to the convergence end point of the inlet section (2), and an outlet section (6) connected to the end point of the throat area (5). The nozzle for cold spray is provided with a spray tube (20) located inside the convergence inlet section (2), the spray tube (20) having a spray hole (12) formed at its end point in such a way as to be placed at the throat area (5) or the outlet section (6) beyond the throat area (5). The speed of the powder flow at the outlet end point of the outlet section (6) reaches 300 - 1,200 m/s.

The presently disclosed subject matter is directed to a system for depositing a chemical of one or more components onto a medium. The system includes a spray assembly for depositing the chemical, a medium for collecting the one or more components forming the chemical, and an enclosure for housing the medium and the spray assembly. The spray assembly includes a capillary for receiving and ejecting a fluid containing the one or more components, a nozzle for receiving and ejecting a gas towards both the medium and the fluid when the fluid is ejected from the capillary, and a spray heater for heating the capillary and the gas. The enclosure includes a translatable drawer for supporting and translating the medium. The system further includes a medium heater for heating the medium.

An apparatus for thermal stabilization according to predetermined parameters that is designed for and can be coupled to atomization devices for air spray-painting systems, of the type comprising a body (1) made of a thermally conductive material provided with at least one outlet (2) for a flow of atomized paint, and provided inside with an atomization circuit (4) comprising a first duct (5) for delivery of a pressurized atomization fluid and a second duct (6) for supplying an amount of paint to be atomized, the apparatus comprising: a conductive body (9) in thermal contact with said body (1) of the atomization device; adjustable means (24, 25, 26, 27, 28) for heat conditioning of the conductive body; and sensors (11) for detecting the temperature of the heat-exchanger body in order to enable or disable said heat-conditioning means in response to a difference between the detected temperature (Tr) and a desired temperature (Tv) of the conductive body (9).
摘要:
An apparatus and system for spraying a skin treatment solution includes air outlets for delivering heated air to improve the efficacy and comfort of the spraying experience. The system may include a base unit that is operable to control an air source and a heating unit that is associated with a hand held skin treatment sprayer. The air source is coupled to a nozzle of the hand held skin treatment sprayer by an air conduit, and the heating unit is disposed within that air conduit. Air flowing through the air conduit is heated by the heating unit. This heated air may be applied while spray is emitted from the nozzle to increase the spray cloud temperature, or may be applied before or after the spray application, with the spray turned off, to warm or dry the skin.

A spray nozzle system for skin treatments includes separate air outlets moving over the skin surface to deliver one or more streams of supplemental air for the purpose of warming or drying the skin surface to improve efficacy and comfort of the spraying experience. The drying air from the auxiliary ports may be applied while spray is emitted from the nozzle to increase the spray cloud temperature, or may be applied before or after the spray application, with the spray turned off, to warm or dry the skin. A heating source is provided to warm the air directed through one or more heated air ports. In the case of air-atomizing nozzles, the heated air is delivered through low pressure ports separately from the air emitted through the nozzle's higher pressure atomizing and pattern shaping orifices to minimize the expansion cooling effect inherent with the spray nozzle ports. In another implementation, the airflow is redirected from the nozzle jets to one or more of the supplemental ports using a control valve which proportions the amount of airflow directed to the main atomizer air jets, the pattern shaping air jets and the supplemental air for drying the skin.
