A method for influencing the wetting angle of the jet exit surface of inkjet print heads

摘要

on spritzmodule with closed nozzles, a polymer solution, preferably highly a peek solution is applied. with the help of a eximer laser of wavelength, the du00fcsenu00f6ffnungen by peek and the layer of kanalmaterial (14 and 16) after the laser ablations - maskenverfahren drilled.subsequently, the surface of the peek layer with a greatly reduced laserintensitu00e4t (11) is irradiated with the same wavelength as the ablationsverfahren used. depending on the desired benetzungswinkel irradiation can be stopped.
