Embodiment Construction

[0046] see Figure 1 to Figure 14 According to the present invention, a large-format dielectric barrier discharge plasma surface treatment system includes a dielectric barrier discharge plasma treatment component A, and an ozone absorption device B is arranged above the dielectric barrier discharge plasma treatment component A.

[0047] The dielectric barrier discharge plasma processing assembly A includes a grounding roller 7, an electrode plate 6 and a gas delivery device. The main shafts 11 at both ends of the grounding roller 7 are rotatably supported on the frame 10, and above the grounding roller 7, a For the electrode plate 6 whose arc surface is concentric with the grounding roller 7 and has an equal discharge distance with the outer peripheral surface of the grounding roller 7, a water cooling channel and a circulating water interface connected to both ends of the electrode plate 6 are provided in the electrode plate 6 9. A gas delivery device is installed between th...

Abstract

The invention discloses a barrier discharge plasma surface treatment system for a large-breath medium, comprising an ozone absorbing device arranged above a barrier discharge plasma treatment component. The barrier discharge plasma treatment component comprises a grounding roller, an electrode plate and a gas transmission device, wherein the two ends of a spindle of the grounding roller are rotationally supported on a machine frame, a pair of electrode plates with arc surfaces coaxial with the grounding roller is mounted on the grounding roller, equal discharge intervals are formed between the electrode plates and the peripheral surface of the grounding roller, and a water cooling channel is arranged in each electrode plate, and the circulating water ports connected with the two ends of the electrode plate are arranged in the corresponding electrode plate; and the gas transmission device is mounted between the two electrode plates. The barrier discharge plasma surface treatment system is strong in treatment strength, long in treatment timeliness, also has the ability of ozone absorption or catalytic decomposition, is applicable to most of large-breath packaging materials such as metal, thin film, leather and the like, and can realize the online plasma surface treatment at different speeds.

Description

technical field [0001] The invention relates to a large-format dielectric barrier discharge plasma surface treatment system, which is suitable for surface treatment of most packaging materials such as metal, film, leather, etc. in a large format (100mm-2000mm). Treatment of plasma surface treatment equipment. Background technique [0002] Printing surface treatment technology was first developed to solve the problem of poor adhesion of plastic film surface printing and coating. Common plastic film basic materials are mainly polypropylene (PP), polyvinyl chloride (PE), polyvinyl chloride (PVC), polyester (PET), etc., whose surface characteristics are due to the polar groups of the molecular structure substrate, crystallization There are great differences in the degree and chemical stability of the plastic, and these factors have a great influence on the adhesion fastness of the printing ink layer. For PS (polystyrene) and PVC with polar structure, there is no need to do sur...
