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
The cleaning solvent for RTV coatings has also been developed in this technical field, but its operation is complicated and the cost is high, and for the cleaning of the surface of charged spraying type RTV coatings, there is no relevant public report in the prior art, because the used formula of charged spraying type RTV coatings Different from general RTV coatings, the technical problems to be overcome are different

Abstract

The invention discloses a cleaning solvent special for anti-pollution flashover of high-voltage electrified-RTV. The cleaning agent is prepared from, by mass, 3-5% of a nonionic surfactant, 3-5% of sodium tripolyphosphate, 1-3% of sodium diethylhexyl sulfosuccinate, 5-6% of alkali, 1-3% of methyl chloroform and the balance water. According to the technical scheme, compared with an existing cleaning agent, the cleaning solvent can effectively remove dirt on the surface of an electrified-spraying type RTV paint insulator, the good hydrophobic nature and the good hydrophobic-migration performance of a coating can be restored, and safe operation of electric equipment can be ensured.

Description

technical field [0001] The invention belongs to the field of cleaning agents, in particular to a surface cleaning agent for charged spraying type RTV coatings. Background technique [0002] With the rapid development of my country's industry, the pollution of a large amount of emissions to the environment is increasing, and the pollution flashover accidents of power transmission and transformation equipment are frequent. The first choice for insulating anti-pollution flashover measures, but as an organic material, room temperature vulcanized rubber is subject to comprehensive utilization of surface discharge, ultraviolet radiation, and surface pollution, and aging phenomena are inevitable. Hydrophobic mobility is also lost. The deterioration of the external insulation performance of RTV will seriously threaten the safe and stable operation of the system. In addition, the RTV coating coated on the surface of the insulator is very thin, and the total amount of anti-pollution fl...
