DEVICE FOR CORONA DISCHARGE TREATMENT

摘要

PURPOSE:To perform corona discharge treatment of an object to be treated at a small power consumption by promoting activation, by blowing a gas from an electrode wire attachment member adapted so that the gas can be blown inside and having a number of gas blow holes on the outer periphery. CONSTITUTION:A base electrode 7 comprising a plastic mold 6 and an electroconductive metal layer 5 and an object 1 to be treated are transferred to the direction of an arrow A. A high voltage is applied between the base electrode 7 and a discharge electrode 8 which comprises a support shaft 9 and an electrode wire attachment member 10 having a hollow part 11 communicating with a gas blow duct 13 and gas blow holes 14 and to which a number of dis charge electrode wires 15 the lowest ends of which are in contact with the surface of the object 1 is attached in the form of pendants and which can vibrate vertically in the direction of an arrow B or can rotate and vibrate in the direction of an arrow C to perform corona discharge treatment of the object 1. At the same time a gas (e.g., air), preferably heated to 30-100 deg.C, is blown from the blow holes 14 to promote activation of the surface of the object 1.
