| 摘要 |
The present invention relates to a spray nozzle for a two-component, air-assisted, low pressure spray system including1) a static mixer having an upstream end and a downstream end whereina) the upstream end has an inlet port for receiving a first liquid component and a second liquid component that is reactive with the first liquid component and the upstream end is dimensioned to be reversibly connected to a dispensing unit for the first and second liquid components, andb) the downstream end has an optionally removable spray tip for introducing the mixed liquid components into an atomizing zone and the downstream end is dimensioned for reversibly connecting the static mixer to a spray section, and2) a spray section having an upstream end and a downstream end whereina) the upstream end of the spray section is dimensioned for being reversibly connecting to the static mixer,b) the spray section has inlet ports for receiving pressurized air andc) the downstream end of the spray section has outlet ports for introducing air into an atomizing zone formed between the outlet ports and the spray tip,wherein the spray tip of the static mixer passes through an orifice in the spray section such that the mixed liquid components are introduced into the atomizing zone.
