Description

Technical Field

[0001] The invention relates to the technical field of spraying, and in particular to a spray gun head with double nozzles and adjustable angles. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivatives of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, etc. Thermal spraying refers to a series of processes in which fine and dispersed metal or non-metallic coating materials are deposited on a prepared substrate surface in a molten or semi-molten state to form a certain spray deposition layer. The coating material can be in powder, ribbon, filament or rod form. The thermal spray gun is provided with the necessary heat by fuel gas, electric arc or plasma arc to heat the thermal spray material to a plastic or molten state, and then it is accelerated by compressed air to make the constrained particle beam impact on the substrate surface. The particles that impact the surface are deformed by the stamping to form laminated thin sheets, which adhere to the prepared substrate surface, then cool and accumulate continuously, and finally form a layered coating. The coating can achieve functions such as high temperature corrosion resistance, wear resistance, heat insulation, and electromagnetic wave resistance due to different coating materials. The spraying operation has high production efficiency and is suitable for manual operations and industrial automation production. It has a wide range of applications, mainly in hardware, plastics, furniture, military industry, shipbuilding and other fields. It is the most commonly used coating method today.
