Embodiment Construction

[0027] The realization of the purpose of the present invention, functional characteristics and advantages will be further described in conjunction with the embodiments and with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0028] refer to figure 1 , the system for improving the hydrophobicity of the surface of stained vulcanized silicone rubber products includes a high-voltage power supply, a jet device and a flow gas generator.

[0029] The jet device includes a jet tube, a high-voltage electrode and a low-voltage electrode. The jet tube has a nozzle and an air inlet. Atmospheric pressure low-temperature plasma is ejected from the nozzle. The jet tube can be a quartz glass tube, a polytetrafluoroethylene tube or a metal tube, etc. The high-voltage electrode and the low-voltage electrode can have a variety of st...

Abstract

The invention provides a method for improving surface hydrophobicity of a contaminated silicon sulfide rubber product. The method includes steps of providing the silicon sulfide rubber product contaminated by dirt; and injecting atmospheric-pressure low-temperature plasma jet on the dirt on the surface of the product for conducting surface treatment. The atmospheric-pressure low-temperature plasma jet acts on the dirt on the surface of the silicon sulfide rubber product and enables hydrophobicity of the surface of the silicon sulfide rubber product to be transferred to the surface of the dirt, so that flashover voltage on the surface of the contaminated silicon sulfide rubber product is kept. The processing efficiency is high. Surface hydrophobicity of contaminated composite insulators, post insulators, insulating bushes and the like can be improved ideally. Therefore, the method for improving surface hydrophobicity of the contaminated silicon sulfide rubber product is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of high-voltage external insulation, and specifically relates to a method and system for improving the surface hydrophobicity of contaminated vulcanized silicone rubber products, especially for surface treatment of high-temperature vulcanized silicone rubber or normal temperature vulcanized silicone rubber products contaminated by kaolin. . Background technique [0002] High temperature vulcanized silicone rubber (HTV) is used as composite insulator shed sheath material and room temperature vulcanized silicone rubber (RTV) coating is applied to the surface of glass insulators and porcelain insulators, which are widely used in power systems. High temperature vulcanization and room temperature vulcanization silicone rubber has hydrophobic migration, that is, the hydrophobicity of the material itself can migrate to the surface of the stained layer, making the surface of the stained layer also hydrophobic. And its hydrop...
