Abstract
The utility model discloses an eaves gutter profiled steel sheet anticorrosion structure, which comprises a base plate (1) for manufacturing the eaves gutter, and is characterized in that the base plate (1) is sprayed with surface treating agent (2), the surface treating agent (2) is coated with phenolic resin anticorrosion paint (3), and the phenolic resin anticorrosion paint (3) is coated with fluorocarbon paint (4). The base plate of the utility model adopts the galvanized steel sheet, overcomes the defect of the chemical reaction of aluminum and HF acid of the prior galvanized steel sheet, and prolongs the service life. The inner layer and the outer layer of the base plate adopt the composite method of the base paint of modified epoxy anticorrosion paint and finish paint of fluorocarbon paint, so the defect of the instability of the acid resistance and anticorrosion of the single protective layer is overcome, the single layered modified epoxy anticorrosion paint can not resist UV, and can age under the radiation of sunlight, while the fluorocarbon paint has good UV-resisting and acid resistant capability, can not easily age and lose effectiveness, and also has good advantage through combining with the modified epoxy anticorrosion paint.
Description
Technical field
The utility model relates to the profiled sheet anticorrosion structure of a kind of roofing eaves gutter and ventilator eaves gutter, especially for the potroom roofing eaves gutter of lightweight steel construction and the anticorrosion structure of ventilator eaves gutter.
Background technology
Electrolytic aluminium belongs to metal smelt technology, main production raw material is an alumina powder, add catalyst A lF3, ice crystal (Na3AlF6), CaF2 is as electrolyte electrolysis production aluminum solutions, inevitably produce HF gas in process of production, after gas cleaning, the part HF gas that purifies fully can not enter in the atmosphere, and when opening the electrolytic cell maintenance, also having the HF gas that remains in electrolytic cell interior 1%～2% distributes in the workshop by outside the skylight discharge factory building, in this process, HF gas is dissolved in the rainwater when meeting with water vapour or when rainy, discharging outside the factory building by the pressing steel plate roofing eaves gutter of potroom and the profiled sheet ventilator eaves gutter of potroom, thereby make the interior HF concentration of eaves gutter the highest, also is the keypoint part and the weak link of the anti-HF corrosion of potroom factory building, eaves gutter in case eaves gutter leaks on the ventilator particularly leaks, and can enter the danger such as electrolytic aluminium blast that cause fusion in the electrolytic cell.
Summary of the invention
The purpose of this utility model is: provide a kind of safe and reliable, prevent the hydrofluoric acid corrosion, improve the steel plate eaves gutter profiled sheet anticorrosion structure of service life, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: structure comprises the substrate (1) of making eaves gutter, on substrate (1), be coated with surface conditioning agent (2), be provided with phenolic resins class corrosion resistant coating (3) on surface conditioning agent (2), phenolic resins class corrosion resistant coating (3) is provided with fluorine carbon lacquer (4).
Above-mentioned eaves gutter profiled sheet anticorrosion structure, the build of described phenolic resins class corrosion resistant coating (3) are 110～130 μ m.
Above-mentioned eaves gutter profiled sheet anticorrosion structure, described substrate (1) are the hot-dip galvanizing sheet steel of 0.5mm～0.8mm thickness, and the two-sided gross mass of zinc coat is 180g/m
2～280g/m
2, yield strength 〉=345MPa.
Above-mentioned eaves gutter profiled sheet anticorrosion structure, the build of described fluorine carbon lacquer (4) is 55～65 μ m.
The utlity model has following advantage: substrate adopts the galvanized steel plain sheet of 0.5～0.8mm, has overcome the shortcoming of in the past bringing aluminium element and HF acid chemically reactive with aluminium plating zinc plate, has prolonged the application life of substrate.The substrate ectonexine adopts the compound practice of modified epoxy corrosion-proof paint priming paint fluorocarbon finish paint; overcome the instable shortcoming of single ply protective layer acid corrosion-resistant; the modified epoxy corrosion-proof paint of while individual layer is UV resistant not; under irradiation of sunlight, can take place aging; and fluorocarbon coating has extraordinary UV resistant and capacity antacid; under solar light irradiation, be difficult to aging and failure, and have and combine extraordinary advantage with modified epoxy corrosion-proof paint.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is an enlarged diagram of the present utility model.
The specific embodiment
Embodiment of the present utility model: adopt hot-dip galvanizing sheet steel as substrate 1, substrate 1 is eliminated rust, cleans preliminary treatment, and sprayed surface inorganic agent 2 on substrate 1 sprays phenolic resins class corrosion resistant coating 3 on surface conditioning agent 2 then, after dry 24 hours, spray fluorine carbon lacquer 4 again.
Phenolic resins class corrosion resistant coating 3 is that 10～12 parts of modified epoxy vinyl resins and blanc fixe mix for 1～2 part, and the build of the phenolic resins class corrosion resistant coating 3 of spraying is 110～130 μ m.The build of fluorine carbon lacquer 4 is 55～65 μ m.
Substrate 1 preferably adopts the hot-dip galvanizing sheet steel of 0.5mm～0.8mm thickness, and the two-sided gross mass of zinc coat is 180g/m
2～280g/m
2, yield strength 〉=345MPa improves antiseptic effect.
Can install after substrate 1 spraying is good, the screw after installation partly and have the place of local corrosion to carry out the local preservative treatment of a benefit.
