For the equipment of porcelain or glass umbellate form, bell-shaped insulator application RTV antifouling flush paint
Technical field
The utility model relates to coating dip coating technical field, especially for the equipment of porcelain or glass umbellate form, bell-shaped insulator application RTV antifouling flush paint, is mainly used in the dip-coating of porcelain or glass umbrella, bell-shaped insulator.
Background technology
Porcelain or glass umbellate form, bell-shaped insulator is widely used in transformer station, is a kind of conventional outdoor insulator, and its application places determines it and needs good antifouling property.In order to avoid the generation of pollution flashover accident, the general many kinds of measures such as adjusting creep distance, water flushing, semi-conducting glaze layer insulator and spraying Hydrophobic Coatings that adopts.But in the antifouling work work of transformer station, adjust the mode of climbing to be restricted, and more exchange device or external insulation parts cost consuming time.Although water backwashing manner is effective, safeguard very hard.Therefore, in order to improve pottery or the electric property of glass insulator under condition is wet in dirt, generally all adopt the mode at its surface spraying RTV antifouling flush paint at present, utilize the hydrophobicity of RTV antifouling flush paint and migration of hydrophobicity to ensure that the pollution flashover voltage of insulator does not reduce.
At present on porcelain or glass umbellate form, bell-shaped pottery insulator, the common method of application RTV antifouling flush paint has artificial brushing, artificial dip-coating and artificial air to spray three kinds of modes, but these three kinds of modes have weak point respectively.
Artificial painting way: in the past, only demand can with, durable, to quality, do not require outward appearance etc., and the market demand is relatively little, this Method compare is welcome.But along with the fast development in market, the requirement of power industry to the construction quality of coating RTV antifouling flush paint is more and more higher, and the manufacturer of insulator gets more and more in addition, competes also more and more fierce, also more and more higher to the quality requirement of product, the inferior position of artificial brushing insulator just slowly highlights, and such as, coating uniformity is poor, presentation quality is poor, have a small amount of bubble inside coating, production efficiency is low, and human cost is more and more higher.
Artificial dip coating manner: coating is relatively more even, but the quality stability of product is not high, is affected by human factors comparatively large, easily occurs substandard products.And hand labor intensity is large, and the efficiency of dip-coating is still lower, can not meet the market demand.
Artificial air's spraying method: this mode also exists weak point equally.One, because umbrella, bell jar shape insulator structure are special, complex contour, especially for the umbrella insulator of two, three layers or more layers, umbrella circular groove seam is dark, easily occurs dead angle in spraying process; Two, spray uneven, thickness is not easily held, and easily produces mass defects such as being coated with gob extensions, skinning, heap sum generation bubble; Three, in spraying process, in order to reach certain coating layer thickness, needing repeatedly to carry out to spray, the program of surface drying, disposablely can not complete spraying, taking time and effort, inefficiency; Four, in spraying process, the volatile solvent discharge in coating is higher, at least more than 50%, large to the pollution of environment, also large to the health threat of people, and manually brush with the volatile solvent discharge of artificial dip coating manner substantially all below 50%, relatively safer.
In sum, existing three kinds of construction methods all cannot meet efficiently, automation coating, the controllability of the gentle quality of high quality water, low environmental protection, high security.Therefore, necessary a kind of new equipment newly developed or technique complete the application of insulator, to improve product quality and production efficiency, and will meet the requirement of environmental protection.
