Problems solved by technology

Affected by the formulation and construction process, the strength and adhesion of RTV coatings vary greatly, and its surface friction is much greater than that of ordinary glass insulators and electric porcelain insulators. It is difficult to remove dirt when flushing with low-pressure water, and excessive flushing pressure Risk of damaging the coating by scrubbing with a rag
Common acid and alkali cleaning solutions are highly corrosive and destructive, and household detergents have poor decontamination ability and many foams, so they are not suitable for cleaning RTV paint insulators

Abstract

The invention discloses a cleaning agent for filth on surface of a room temperature vulcaniza-tion (RTV) coating insulator. The cleaning agent is formed by mixing at least two of ethylene diamine tetraacetic acid, sodium glycollate, sodium oxalate and sodium gluconate, sodium polyacrylate, hydroxyethylidene phosphonic acid disodium, alkylphenol ethoxylates serving as a surfactant, fatty alcohol-polyoxyethylene ether serving as a penetrant and water. When the cleaning agent is used, the filth on the surface of the RTV coating insulator is cleaned through combined action of mechanisms such as permeation, complexation, dispersion and expansion. Therefore, the cleaning agent has the advantages of being low in cost, simple in operation, convenient to implement, complete in filth removing, freeof damage to RTV coating and corrosion to metal parts of an insulator pillar and favorable for wide popularization.

Description

technical field [0001] The present invention relates to a cleaning agent, in particular to an RTV (abbreviation for Room Temperature Vulcanized Silicone Rubber in English, and the Chinese translation is Room Temperature Vulcanized Silicone Rubber.) Cleaning agent for surface contamination of paint insulators. Background technique [0002] RTV coatings can significantly increase the pollution flashover voltage of insulators and reduce the risk of pollution flashover of insulators in heavily polluted areas. Spraying RTV paint on the surface of insulators to prevent pollution flashover has been widely used and is an effective anti-pollution flashover measure. The working principle of RTV coating to prevent pollution flashover accidents is to use its two characteristics of water repellency and water repellency for construction. If it fails, it indicates that the life of the coating has come to an end. Substations in heavily polluted areas still have a certain proportion of poll...
