摘要

#CMT# #/CMT# An opposing electrode(2) over which plastic film is passed faces a high tension electrode(1) comprising electrode segments(6) aligned in the film movement direction. Discharge edges of each segment are divided into discharge tongues(7) spaced in the film movement direction and projecting towards the film. Tongues of adjacent segments are offset from each other in the film movement direction and form gaps. #CMT# : #/CMT# Adjacent electrode segments(6) are spaced transverse to the film movement direction. Spacing of segments is 1-3 times their thickness. Segments are cranked or set saw-like transverse to the film movement direction. #CMT#USE : #/CMT# For surface activation of plastic films. #CMT#ADVANTAGE : #/CMT# More uniform surface activation is achieved across the treatment area. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic cross-section of the corona discharge equipment. 1 : high tension electrode 2 : opposing electrode 6 : electrode segments 7 : tongue #CMT#METALLURGY : #/CMT# Preferred Materials: Segments are made of stainless steel.
