| Summary: | The article is devoted to the use of jet-droplet optical measuring
systems (JDOMS) for monitoring the electrization of products
such as metallized polymer films during their laser perforation.
The article shows that the main reason for the electrization of
films is the removal of matter by a laser pulse with the formation
in the microvolume of the plasma, a gaseous ionizing substance
and its partial deposition on the edge of the perforated hole in the
absence of contact with the metallization of the film.
The JDOMS operating mode with the formation of a monodisperse coherent controlled charged droplet flow and video recording of
the trajectory of charged droplets along the centers of perforated
holes near the film is described based on the measurements of
which electrization is controlled.
The maximum charges of the perforated holes of the film and
moving drops are determined. The displacements from their
interaction and the JDOMS sensitivity limit for electrification
control are calculated. The requirements to the means of video
recording and processing of the obtained stroboscopic micrographs
are determined. |
