Description

Technical Field

[0001] The utility model relates to the technical field of spray gun nozzle equipment, in particular to a spray gun nozzle for waterborne epoxy coatings. Background Technique

[0002] Currently: The coating spraying tool - the coating nozzle is applied to harsh working conditions such as high-speed over-flow erosion and cavitation of coatings. Generally, the spraying flow rate is 200 - 300 ml / min, but for some special coatings, the spraying flow rate is as high as 400 - 500 ml / min. Most of the existing high-speed nozzles adopt alloy steel materials and cemented carbide materials. The alloy steel material has the worst wear resistance and is easy to be corroded. The cemented carbide material has general wear resistance, is magnetic, generates electromagnetic eddy current phenomena with TiO2-based semiconductor materials, and has a high price and high use cost.

[0003] The application number is CN202120300774.1, which discloses a spray gun nozzle for high-speed spraying of titanium dioxide-based semiconductor heat-insulating coatings, including a nozzle body and a stainless steel sleeve. The nozzle body is arranged inside the stainless steel sleeve by interference fit, and the material of the nozzle body is cermet. The spray gun nozzle of the utility model has a split structure, which is composed of a nozzle body and a stainless steel sleeve. The nozzle body and the stainless steel sleeve are made of cermet and stainless steel respectively, and can solve the problems of poor wear resistance, easy corrosion, and easy occurrence of electromagnetic eddy current phenomena of the existing high-speed nozzles.

[0004] The spray gun nozzle for high-speed spraying of titanium dioxide-based semiconductor heat-insulating coatings disclosed in the above document has the following defects: During the use of the nozzle, it is necessary to fixedly install the nozzle on the spray gun head. When the spraying requirements are different, the nozzle needs to be replaced. The nozzle is not provided with a corresponding connection structure, which is not convenient for disassembly and replacement.

[0005] It can be seen that the existing spray gun nozzles do not have the function of disassembly and replacement, and it is necessary to improve the existing deficiencies to provide a function that can disassemble and replace the spray gun nozzles. Content of the Utility Model
