Description

Technical Field

[0001] This utility model belongs to the technical field of atomizing spray guns, specifically relating to an atomizing spray gun for metal surface treatment coatings. Background Technology

[0002] Metal surface treatment coating atomizing spray guns are core equipment in the industrial coating field. Through efficient atomization technology, they transform liquid coatings into uniform, fine paint mist particles, achieving precise coverage of metal workpieces. Their core value lies in improving coating quality and resource utilization: employing principles such as compressed air (traditional air guns), high-pressure fluid (airless guns), or electrostatic adsorption (electrostatic guns), the coating forms fine droplets of 15-100 microns, ensuring excellent leveling, adhesion, and corrosion resistance. Targeting the characteristics of metal surfaces, the equipment is compatible with high-adhesion coatings such as epoxy, polyurethane, and zinc-rich primers, significantly enhancing rust prevention and wear resistance.

[0003] Most existing metal surface treatment coating atomizing spray guns use spring-loaded or threaded adjustment mechanisms, with the flow channel opening directly controlled by a manual knob. In the continuous vibration environment of spraying operations, this design is prone to unexpected deviations in the flow channel opening, leading to fluctuations in the coating-compressed air mixing ratio and resulting in uneven coating thickness. Therefore, a metal surface treatment coating atomizing spray gun is needed to help solve this problem. Utility Model Content
