Embodiment Construction

[0011] A surface treatment process for a cylindrical plastic container. The process uses a high-frequency high-voltage device to discharge the surface of the plastic container through electrode discharge. The distance between the electrode and the plastic container to be treated is 1.5mm, and the electrode is a double-headed electrode. , the thickness of the electrode is 4-4.5cm, there are 2-4 shallow grooves at the edge of the electrode, the instantaneous output voltage of the electrode is controlled to 16000-18000 volts, and the surface of the plastic container to be treated is coated with UV ink. UV radiation lamp irradiation. Improve its processing efficiency and strengthen the processing effect.

Abstract

The invention discloses a surface treatment process for a cylindrical plastic container. According to the process, a high-frequency high-voltage device is used for performing surface treatment on the plastic container through electrode discharging, the distance between an electrode and the plastic container to be treated is 1.5 m, the surface of the plastic container to be treated is coated with UV (ultraviolet) ink, and a UV radiation lamp is arranged for irradiation during treatment. According to the process, defects in the prior art are overcome, the electrode is a double-end electrode, the thickness of the electrode is increased, and 2-4 shallow grooves are formed in a knife edge of the electrode, so that arcs produced by the electrode are needle-shaped arcs, the surface treatment effect is improved, the treatment speed is 150 pieces per second, and the treatment efficiency is improved; and the UV radiation lamp is added during treatment, so that the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of plastic surfaces, in particular to a surface treatment process for cylindrical plastic containers. Background technique [0002] The existing plastic surface treatment is to increase the adhesion of the plastic surface, mainly using a high-frequency high-voltage device to carry out surface treatment on the carrier through electrode discharge. The distance between the electrode and the carrier to be treated is 2 mm, and the instantaneous output voltage of the electrode is 500-15000 volts. Make it generate high-voltage discharge instantaneously, produce small and dense purple-blue sparks, and the air around the sparks will generate various plasmas after ionization. Under the action of a strong electric field, the accelerated impact on the plastic surface can induce the chemical bonds of the plastic surface molecules to break and degrade. Thereby increasing the surface roughness of the plastic. However, thi...
