In the polyethylene or polypropylene plastic film or composite surface of the printing, if the treatmentis ineffective without the
prior, it is because the film production process, infiltration additives, film, etc., after the surface wax exudation. Thinfilm electrical
insulation performance is good, not with the polar groups, and other substances is not easy phase adsorption. Blow molding of
thinfilm surface is smooth pull, so its ability to lower surface attached to worse. I plant the impact of aircraft development and
production ofthe film awakened the impact on the film surface treatment, after treatment, their printing and composite performance
improved significantly. This is because the spark discharge of air ionization, zone, can go to oil. Ozone decompositionof the atomic
oxygen is extremely lively, can stimulate the membrane surface of the basic group, easytophase adsorption, and other substances.
EDM intensive impact to the surface of the formation of many small pits, smooth surface become astringentto facilitate the infiltration
of small pits to make adhesives, printed and posted next to improve results.
EDM processing, thin ink by the upper and lower the gap between theelectrodes, as shown in Figure 3. Dealing with the power
supply for highfrequency power supply, processing power, voltage and current intensity and a thin ink material, temperature, width
and speed of operation and other relevant.
BGDC series corona processor is easy to operate ,just a board and turn rotary switch handle can even adjust the output voltage,
when a short circuit ,will automatically stop the output voltage,and alarm .main circuit using silicon oscillator circuit ,and the line is simple
and stable ,not easily maintenance .By adjusting the spark discharge most of the length of electrodes can handle different widths of film .
Electrode spark generated uniform.
