Disclosed is a fumigation vaporizer capable of quickly vaporizing a fumigant, which is widely used in agriculture or quarantine to control insects or weeds, thereby safely and effectively carrying out fumigation, as compared to a conventional process. The fumigation vaporizer includes a housing, a fumigant supply pipe, a heater, a non-explosive gas supply member, a gas supply pipe, a vessel-type heater, a gas discharge pipe, and a controller. The housing is provided with a heating hollow portion at the lower portion of the inner cavity, in which the non-explosive gas heated and supplied by the vessel-type heater heats a bottom surface of the inner cavity while passing through the heating hollow portion. A bottom surface of the heating hollow portion is provided with an inlet port through which the non-explosive gas passes, and a top surface of the heating hollow portion opposite to the inlet portion is provided with an outlet port through which the non-explosive gas passing the heating hollow portion is supplied to the gas discharge pipe installed to the inner cavity.

An adjustable atomizer nozzle assembly includes an assembly body; first and second side nozzle components, including compressed air tubes, liquid tubes, liquid heater, air heater, atomizer nozzles, which are mounted with an impingement angle to create a combined aerosol stream with reduced droplet size. An adjustable atomizer nozzle system includes a nozzle assembly; a mast assembly; a self-coiling line assembly, including a compressed air line, a pressurized liquid line, and a power line; a pressure tank; a compressor; a power supply; a mounting base; and wheels. A nozzle assembly can include one atomizer nozzle with a liquid heater. A method of use includes providing an adjustable atomizer nozzle system, configuring impingement for spraying, spraying a room, configuring impingement for fogging, and fogging the room.

Disclosed are a laser assisted cold spray repair device and process method for aviation-grade aluminum alloy structural parts. In the present disclosure, a laser device, a high-pressure gas source, a powder feeder, a water cooling system, a reflector, an integrated spray gun, a mobile platform, an air pipe, a powder-gas mixed channel, a lower-pressure powder-gas powder feeding port, an air pressure regulating valve, a high-pressure airflow heater and a powder pipe are included. The powder spray gun and a heating laser source are connected coaxially, and a processing zone of the mobile platform is provided with a specimen to be processed. In the present disclosure, fatigue properties of repaired aviation-grade aluminum alloy specimens are restored to an original state before damage and satisfy service requirements.

The present disclosure relates to a cold spray metal process for providing an electrical connection within a multilayered composite article. The present disclosure relates to a cold sprayed metal coated article or a structural component having a polymeric composite material having at least one surface, a thermoplastic electrochemical insulating layer on the at least one surface, an electrical circuit may include a cold sprayed metal coating present on at least a portion of a surface of the electrochemical insulating layer, and at least one additional layer, the at least one additional layer encapsulating at least a portion of the cold sprayed metal between the additional layer and the electrochemical insulating layer. The structural component may include a cold sprayed metal coating having one or more non-continuous segments, where the one or more non-continuous segments are not in lateral contact with one another.
