摘要

PURPOSE: To apply glow discharge plasma treatment to a perforated tubular article composed of a plastic material or the like under atmospheric pressure by applying AC voltage while introducing gas, treatment gas or mixed gas of them generating glow discharge stably. ;CONSTITUTION: After the base material to be treated (e.g., tube of two-hole structure) opened to the atmosphere at one end thereof and connected to a gas introducing line 6 at the other end thereof is set to the inside of an electrode main body 1, the mass flow control valves 5a, 5b provided to gas introducing lines 6a, 6b are opened to continuously introduce mixed gas consisting of gas A stabilizing glow discharge and treatment gas B into the base material 4 to be treated and AC voltage is applied under pressure near to atmospheric pressure to form a glow plasma region to perform treatment. The mass flow control valves 5a, 5b adjust the introducing amt. of the treatment gas and gas stably generating low discharge such as helium introduced into the holes of the base material 4 to be treated and the mixing ratio of them.;COPYRIGHT: (C)1996,JPO
