Abstract

The invention introduces an anti-pollution flashover coating cleaning agent. The cleaning agent is prepared by mixing the following preparation raw materials in percentage by weight: 1-5% of alkyl polyglucoside, 1-5% of N-alkyl acyl-N-O-methylglucose, 0.2-5% of a non-ionic type Gemini surfactant, 1-5% of hetero-alcohol polyoxyethylene polyoxypropylene, 0.01-0.05% of an organic silicon defoamer and the balance of water. The cleaning agent can be used for cleaning transformer oil on an anti-pollution flashover coating surface under the comprehensive action of mechanisms such as permeating, emulsifying, dispersing and the like. The cleaning agent has excellent wettability and permeability; the cleaning agent can permeate into the pores of silicon rubber and remove oil dirt absorbed in the pores, so that the oil dirt cleaning efficiency is increased; and the cleaning agent has excellent permeating, emulsifying and dispersing performances and good compatibility with various surfactants, auxiliaries, additives and solvents. The cleaning agent has the advantages of thorough oil dirt removing, no toxicity, no stimulus, no corrosion and high biodegradability.

Description

A kind of antifouling flash coating layer clean-out system

Technical field

The present invention relates to a kind of clean-out system, relate in particular to a kind of for the clean-out system that cleans the antifouling flash coating layer that is polluted by transformer oil.

Background technology

As the remedial measures of the anti-pollution flashover work of power equipment, the room temperature vulcanized silicone rubber antifouling flash coating layer dodges performance with its excellent resistant, has been widely used on the whole dc fields equipment outer insulation.Dc fields equipment outer insulation pollution flashover characteristic largely is subjected to the restriction of insulation characterisitic of the room temperature vulcanized silicone rubber of surface-coated.The performance that room temperature vulcanized silicone rubber is good is mainly reflected in excellent hydrophobic nature and migration of hydrophobicity.Reasons such as transformer high-voltage turnover thread casing, high-tension side oil filled bushing etc. apply the equipment of antifouling flash coating layers, and not good or pile crown is overheated owing to processing quality easily produce the leakage of oil defective.There are some researches show that equipment oil leakages such as transformer bushing have considerable influence to the insulation characterisitic of room temperature vulcanized silicone rubber.The high temperature transformer oil can infiltrate into silicon rubber inside gradually, thereby reduces room temperature vulcanized silicone rubber hydrophobic nature and hydrophobic restorability, may cause current conversion station DC insulation annular tube pollution flashover when serious.And the antifouling flash coating layer surface of covering oil adheres to filthyly easily, and the antifouling flash coating layer surface contamination that this specific character will cause stained by oil is more serious.The non-benign circulation of covering oil-contamination-cover oil will further make the pollution level aggravation on antifouling flash coating layer surface, and common cleaning can not be removed the transformer greasy dirt on antifouling flash coating layer surface.2012, the patent No. is that the patent documentation of ZL201210122361.4 has been introduced a kind of RTV coating insulator surface filth clean-out system, this clean-out system ground has successfully solved the cleaning difficult problem of insulator dirt-proof coatingsurface based on the dunghill of inorganic salt, has guaranteed the safe operation of power equipment effectively.But this kind clean-out system manifests deficiency for the antifouling flash coating layer cleansing power that is subjected to the transformer oil pollution, can't thoroughly remove the transformer greasy dirt that is adsorbed in the self cure silicon silicon rubber hole.

Summary of the invention

The technical problem to be solved in the present invention is, defective at prior art, a kind of antifouling flash coating layer clean-out system is provided, the transformer oil that this clean-out system can effectively be removed the insulator dirt-proof coating surface pollutes, recover the good hydrophobic nature of its room temperature vulcanized silicone rubber and migration of hydrophobicity, thereby possess the ability of effective assurance power equipment safety operation.

Technical scheme of the present invention is that a kind of antifouling flash coating layer clean-out system of this that provides is to be equipped with raw material as following weight percent to be mixed:

APG 1～5%,

N-alkyloyl-N-methyl glucoside amine 1～5%,

Non-ionic type Gemini tensio-active agent 0.2～5%,

Isomery alcohol polyoxyethylene poly-oxygen propylene aether 1～5%,

Silicone antifoam agent 0.01～0.05%,

Surplus is water.

By above joining following following concrete steps when this a kind of antifouling flash coating layer clean-out system of the present invention that raw material mixes uses:

(1), described antifouling flush paint clean-out system is contained in watering can, be under the power down mode at equipment to be cleaned and start watering can, the insulator dirt-proof coatingsurface that antifouling flush paint clean-out system in the watering can is sprayed at described equipment to be cleaned is implemented Fouling Cleaning, scavenging period 2～3 minutes;

(2), use rag to be stained with the antifouling flush paint clean-out system that dips in the described watering can of step (1), use the rag that dips in the antifouling flush paint clean-out system then, clean the insulator dirt-proof coatingsurface of the equipment to be cleaned that cleaned through step (1);

(3), use the insulator dirt-proof coatingsurface of the equipment to be cleaned that flushing with clean water cleaned through step (2).

The invention has the beneficial effects as follows that this antifouling flash coating layer clean-out system that provides can be used for cleaning the antifouling flash coating layer surface of being polluted by transformer oil.This clean-out system is removed the transformer oil on antifouling flash coating layer surface by the comprehensive action of mechanism such as infiltration, emulsification, dispersion.The contained APG of this clean-out system is the more comprehensive nonionogenic tenside of a kind of performance, fully biodegradable, and the characteristic except possessing common nonionic and anion surfactant also has good surfactivity and mildness concurrently.Its wettability, penetrating quality excellence; Contained N-alkyloyl-N-methyl glucoside amine also has fabulous surfactivity, with the composite use of isomery alcohol polyoxyethylene poly-oxygen propylene aether good synergy is arranged, and biological degradability.This non-ionic type Gemini tensio-active agent has low surface tension and excellent wetting capacity energy.If produce bigger synergistic effect with other nonionic surface active agent is composite.Also can be deep into the silicon rubber hole, drive away and the greasy dirt that adsorbs in the hole, improve the greasy dirt cleaning efficiency; The contained isomery of this clean-out system alcohol polyoxyethylene poly-oxygen propylene aether has complete biodegradability, and infiltration, emulsification, dispersive ability excellence are good with various tensio-active agents, auxiliary agent, additive, solvent compatibleness.So make product of the present invention have greasy dirt remove thorough, nontoxic, non-stimulated, do not corrode, thereby and the high advantage that is beneficial to extensive popularization of biological degradability.
