Material surface treatment device based on air glow discharge plasma

Abstract

The invention discloses a material surface treatment device based on an air glow discharge plasma. The material surface treatment device comprises a high voltage electrode 1, a reverse high voltage electrode 2, a first insulating medium 3, a second insulating medium 4, a first ground electrode 5, a second ground electrode 6, a treated material 7 and a roller 8. The high voltage electrode 1, the first insulating medium 3 and the first ground electrode 5 are tightly laminated in order to form an upper side laminated electrode, the reverse high voltage electrode 2, the second insulating medium 4and the second ground electrode 6 are tightly laminated in order to form a lower side laminated electrode, the upper side laminated electrode and the lower side laminated electrode are mutually parallel and oppositely arranged, the treated material 7 is inserted in parallel into the air gap of the two laminated electrodes, the roller 8 is laminated at the surface of the material, and the roller isrolled to drive the material motion. The device is low in discharge voltage, good in discharge uniformity and good in material treatment effect, and the high efficiency and continuous modification onboth sides of the material are achieved.

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...
