Abstract
The invention discloses a coating method for an insulator antifouling flashover coating, comprising the following steps: firstly clearing sundries and moisture on an insulating surface, and brush coating with a brush or spray coating with a spray gun, wherein the coating is diluted by adding 12-18% of petroleum ether or 120# solvent oil in case of coating with the spray gun, the coating or spraying thickness is 0.4mm, the coating or spraying are conducted for three times, the amount of the material used is 5m<2>/kg, the coating temperature is -20-40 DEG C; and after the brush coating or spray coating is finished, ventilating an insulator in ventilation equipment at 25-40 DEG C for 5-7 hours. Electric arc resisting additive is added in the insulator antifouling flashover coating provided by the invention. The antifouling flashover coating coated by the coating method has better anti-cracking performance, stable quality and low damage to human body.
Description
Technical field
The present invention relates to a kind of coating process of antifouling flush paint, relate in particular to electrical network prevent and reduce natural disasters in the coating process of antifouling flush paint in the insulator surface antifouling property in the anti-soil technology.
Background technology
Extensively all are prone to pollute on the electric equipment porcelain external insulation of fog trickles and use antifouling flush paint in power plant high voltage station, transformer station of power supply administration and transmission & distribution cable insulator and petrochemical industry, iron and steel, mining industry.
The power transmission and transformation equipment outer insulation pollution flashover that atmosphere pollution causes has caused serious harm to power system.The insulator that on transmission line of electricity, adopts is classified by dielectric substance, and three types of porcelain, glass, composite organic insulator are arranged.The problem of these insulator chain flashovers is also very outstanding, has a strong impact on safe operation of power system.After pollution flashover accident took place, reclosing was difficult for, and causes large tracts of land to have a power failure for a long time, tend to cause great economic loss, and be exactly that the resistant that improves insulator is as much as possible dodged ability so avoid the direct and effective measures of pollution flashover accident.At present, the method for up-to-date raising insulator resistant sudden strain of a muscle ability is the coating that is coated with anti-pollution flashover at insulator surface.But the method for generally using of immersing wastes time and energy, and human body is also had harm.
Summary of the invention
The object of the present invention is to provide a kind of steady quality, the insulator dirt-proof coating coating process little to the human injury.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
At first remove the foreign material and the moisture of insulating surface; Spray with the brush brushing or with spray gun then; The benzinum of adding 12～18% or 120# solvent naphtha dilution when spraying with spray gun; Brushing or coating thickness are 0.3 ㎜～0.5 ㎜, and brushing or spraying number of times are 3 times, and materials are 5 ㎡/㎏; Coating temperature is-20 ℃～40 ℃, and brushing or spraying end back are placed on insulator in the ventilation equipment under 25 ℃～40 ℃ and ventilated 5～7 hours.Add the arc resistant additive in the said insulator dirt-proof coating.
The invention has the beneficial effects as follows: anti-be full of cracks performance is good, and steady quality is little to the human injury.
The specific embodiment
Coating process of the present invention is performed such: foreign material and the moisture of at first removing insulating surface with cotton; With the brush brushing or with the spray gun spraying, add 13% benzinum or the dilution of 120# solvent naphtha when spraying with spray gun then, brushing or coating thickness are 0.4 ㎜; Brushing or spraying number of times are 3 times; Whenever be coated with one time, placed 5 hours, total materials are 5 ㎡/㎏; Coating temperature is-20 ℃～40 ℃, and brushing or spraying end back are placed on insulator in the ventilation equipment under 35 ℃ and ventilated 7 hours.Added in the edge antifouling flush paint among the present invention and be the arc resistant additive of total materials quality 0.02%.
The anti-be full of cracks of this coating process performance is good, and steady quality is little to the human injury.
Explanation is at last; Above embodiment only is used to explain technical scheme of the present invention and is unrestricted; Other modifications that those of ordinary skills make technical scheme of the present invention perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of technical scheme of the present invention, all should cover in the protection claimed range of the present invention.
