| 摘要 |
<p>The present invention relates to a spray nozzle for a two-component, air assisted, low-pressure spray system including a) a static mixer (1) having an inlet port on its upstream end for receiving a first liquid component and a second liquid component that is reactive with the first liquid component and having on its downstream end an optionally removable spray tip (5) for introducing the mixed liquid components into an atomizing zone (16), b) a static mixer shroud (7), which encases the static mixer (1), is dimensioned on its upstream end for connecting the shroud to a dispensing unit for the first and second liquid components and has on its downstream end an optionally removable spray section (10) having inlet ports for receiving pressurized air and outlet ports (18) for introducing air into the atomizing zone, wherein the spray tip (5) passes through an orifice in the spray section (10) such that the mixed liquid components are introduced into the atomizing zone (16). The present invention also relates to a process for spraying a two-component composition using the spray nozzle.</p> |
