A material surface treatment device based on air glow discharge plasma

Abstract

The invention discloses a material surface treatment device based on air glow discharge plasma, comprising a high-voltage electrode 1, a reverse high-voltage electrode 2, an insulating medium 1 3, an insulating medium 2 4, a grounding electrode 5, a grounding electrode 2 6, The material to be processed 7, the roller 8, the high-voltage electrode 1, the insulating medium 1 3, and the grounding electrode 5 are closely attached in sequence to form an upper-side laminated electrode. The reverse high-voltage electrode 2, the insulating medium 2 4, and the grounding electrode 2 and 6 are closely attached in turn to form the lower laminated electrode. The upper laminated electrode and the lower laminated electrode are placed parallel to each other, and the material 7 to be processed is inserted into the air gap between the two laminated electrodes in parallel. It fits on the surface of the material and drives the material to move by rolling. The device has the advantages of low discharge voltage, good discharge uniformity, good material treatment effect, and simultaneous high-efficiency and continuous modification of the surfaces on both sides of the material.

Description

technical field [0001] The invention relates to the field of polymer material surface treatment, in particular to a material surface treatment device based on air glow discharge plasma. Background technique [0002] At present, there are mainly two methods of surface modification of polymers, chemical and physical. Chemical modification methods are divided into chemical etching, coupling and surface grafting. Physical modification methods include γ-ray radiation, ultrasonic impregnation modification and plasma surface modification. The process of chemically modifying high molecular polymer is simple and the effect is remarkable, but there is environmental pollution, and it will destroy its internal structure, resulting in a large loss of strength. γ-ray radiation and ultrasonic impregnation modification have not yet been industrialized due to equipment reasons. [0003] Low-temperature plasma surface modification technology has significant advantages such as high efficien...
