| 摘要 |
The invention relates to an improved nozzle for spray guns intended for paints and derivatives, based on fluid transfer, comprising a resin outlet (9), a catalyst inlet (1) and air crests (8) with nozzle (7) outlet holes, said nozzle housing internal channels through which the catalyst is conveyed to the holes (2). The nozzle also includes other internal pressurized air inlet channels (4) which convey the air through the nozzle to different elements on the surface thereof, such as, in a first phase, outlets for forming the resin fan and, in a second phase, outlets (3) for generating a cloud that sprays the catalyst, in which the resin fluids and the catalyst or other components are mixed outside the nozzle (7) at the moment of use. In addition, the nozzle includes external holes (6) for extra air supply. |
