Abstract
The invention discloses an anticorrosion technology of an electric tower. The technology comprises a light-corrosion treatment technology and a moderate-corrosion treatment technology. According to the light-corrosion treatment technology, a slightly-rusted place on the surface of the tower is cleaned through microfiber cloth, and anticorrosive primer and finish paint are sprayed; and according to the moderate-corrosion treatment technology, for rust spots with the superficial area smaller than one square centimeter and the depth smaller than 2mm and non-visible dirt, steel wires or a nylon brush is used for brushing away and derusting dirty marks, epoxy zinc-rich primer is sprayed firstly, then, the anticorrosive primer is sprayed, and the finish paint is sprayed. Compared with the prior art, the strict spraying technological steps are implemented, a standard spraying thickness is adopted, and the sprayed paint is not prone to falling off; the service life of the electric tower can be effectively prolonged; the technology has the advantages of being simple in operation step, easy to implement and capable of being kept free of deterioration for a long time, is a high-quality maintenance technology of the electric tower, and has the use and popularization value.
Description
Technical field
The present invention relates to a kind of electric tower service procedure, particularly relate to a kind of electric tower anticorrosion process.
Background technology
For the coastal transmission line of electricity of running time more than 20 years, be subject to polluting containing a large amount of sulphate cpd in air.There is corrosion and the double-circuit line engineering characteristic that can not simultaneously have a power failure in tower material, therefore needs, by carrying out the construction of electric tower oiling corrosion-resistant to it, to reach and extend service life, promote the object of environmental protection.And spraying technology of the prior art not science, thickness etc. require strict not, the paint after spraying are easily come off, bothersome effort, are difficult to promote.
Summary of the invention
Object of the present invention is just to provide a kind of electric tower anticorrosion process to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes mild corrosion treatment process and moderate corrosion treatment process:
Described mild corrosion treatment process: surface has the local hundred clean rags that slightly get rusty clean clean, is coated with anti-corrosion primer and finish paint;
Described moderate corrosion treatment process: surface area is less than 1 square centimeter, the rust spot that the degree of depth is less than 2 millimeters, without visible dirt steel wire or nylon bruss removing rust deposite mark, is first coated with epoxy zinc-rich paint, then is coated with anti-corrosion primer, and then be coated with one deck finish paint.
Particularly, thickness >=75 μm of described epoxy zinc-rich paint; Thickness >=50 μm of described anti-corrosion primer; Thickness >=100 μm of described finish paint.
As preferably, the anti-corrosion primer of described mild corrosion treatment process and the gross thickness of finish paint are 150-250 μm; The gross thickness of the anti-corrosion primer of described moderate corrosion treatment process, epoxy zinc-rich paint and finish paint is 225-350 μm.
Particularly, the formula of described epoxy zinc-rich paint is: thin zinc powder 70%, epoxy resin 12%, organobentonite 2% and solvent 16%; The formula of described anti-corrosion primer is: trihydroxy polyethers 65%, vulcabond 12%, dibutyl ester 10%, coal tar 6%, quartz powder 4% part, castor oil 1% and diamine MOCA2%.
Beneficial effect of the present invention is:
The present invention is a kind of electric tower anticorrosion process, compared with prior art, the present invention adopts strict spraying coating process step to implement, and adopts the coating thickness of standard, makes the paint difficult drop-off after spraying, but also effectively can extend the service life of electric tower, operating procedure of the present invention is simple, implements easily, and the advantage of the matter that can keep remaining unchanged for a long period of time, be a kind of high-quality service procedure of electric tower, there is the value promoted the use of.
Detailed description of the invention
The invention will be further described below:
The present invention includes mild corrosion treatment process and moderate corrosion treatment process:
Described mild corrosion treatment process: surface has the local hundred clean rags that slightly get rusty clean clean, is coated with anti-corrosion primer and finish paint; Gross thickness is 150-250 μm;
Described moderate corrosion treatment process: surface area is less than 1 square centimeter, the rust spot that the degree of depth is less than 2 millimeters, without visible dirt steel wire or nylon bruss removing rust deposite mark, is first coated with epoxy zinc-rich paint, then is coated with anti-corrosion primer, and then be coated with one deck finish paint; Gross thickness is 225-350 μm.
Particularly, thickness >=75 μm of described epoxy zinc-rich paint; Thickness >=50 μm of described anti-corrosion primer; Thickness >=100 μm of described finish paint.The formula of described epoxy zinc-rich paint is: thin zinc powder 70%, epoxy resin 12%, organobentonite 2% and solvent 16%; The formula of described anti-corrosion primer is: trihydroxy polyethers 65%, vulcabond 12%, dibutyl ester 10%, coal tar 6%, quartz powder 4% part, castor oil 1% and diamine MOCA2%.
Too much at paint water consumption, when " raindrop " phenomenon appears in coating, remove with professional flat chisel, uniform coating thickness is guaranteed in coating again.There is dew point in the gap between steel tower bolt or two blocks of iron, selects small brushes to carry out brushing and avoid without coating phenomenon.Larger tower material plane, adopts " round brush " to get suitably paint brushing evenly.Forbid to occur painting ground of being scattered in a large number, cause environment pollution.There is the unfavorable condition of cracking, peeling in coating, corrosion component surface should be cleared up thoroughly and be brushed in time; When air humidity is greater than 85%, oiling is forbidden to be constructed.In the undried situation of coating, meet misty rain weather, cause coating shedding and cover uneven situation, again clear up before secondary brushing, brush according to former scheme.Tower material is cleaned out, and coating attachment is insecure.Check whether because the situations such as weather, transport, storage, match ratio cause coating be not suitable for using and propose replacing in time.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
