Single tube self-absorption type particle spray gun nozzle

Abstract

The invention provides a single tube self-absorption type particle spray gun nozzle which is solid particle filler spraying equipment used for a military stealthy coating, a protective coating and the like and can be directly mounted on a conventional air spray gun for spraying a commonly used coating. The equipment mainly comprises a large-aperture nozzle, a jet-flow joint, a feeding rubber tube and the like. According to the single tube self-absorption type particle spray gun nozzle, the solid particle filler can be directly, uniformly and rapidly sprayed, and the spreading mode that manual spreading by hands only can be adopted conventionally is changed, so that the construction efficiency and the spray effect of the equipment and facility surface coating are greatly improved; and meanwhile, the equipment further has good wear resistance, wide application range and convenience in operation and is simple to dismount and maintain.

Description

technical field [0001] The invention belongs to the field of paint spraying construction technology, and is specifically used for rapid spraying of solid particle fillers, and relates to solid particle spraying equipment. Background technique [0002] With our military's increasing performance requirements for active military equipment and facilities in terms of anti-corrosion and stealth, a large number of functional coatings such as anti-corrosion and stealth are used on the surface of equipment and facilities. During the construction of these coatings, it is sometimes necessary to evenly disperse larger-diameter solid particles in the coating to achieve special functions such as scattering of electromagnetic waves or anti-skid of the coating. At this time, the dispersion efficiency of solid particles in the coating And the dispersion state directly affects the construction speed and function of the coating. The uniform and rapid dispersion of solid particles with larger ...

AI Technical Summary

Problems solved by technology

[0004] (1) The efficiency is not high

Can only be operated manually, cannot be operated continuously, and cannot be mechanized

[0005] (2) Filling utilization rate is low

Loss of filler occurs during manual spreading

[0006] (3) Poor distribution effect

[0009] (2) There are many basic theoretical studies and few physical studies

[0011] There is still no nozzle equipment on the market that can be used in conjunction with the existing common spray guns for large-particle spraying to achieve rapid and uniform coating of large-particle fillers
