Abstract
The invention relates to a paint spraying method for an aluminum tip of a blade of a wind generating set, wherein the spraying operation area of the spraying method is a connecting area of the aluminum tip of the blade and glass fiber reinforced plastic and an integral area of the aluminum tip of the blade; before blade coating of blade aluminum tip putty, drying and surface impurity cleaning of an aluminum tip; coating putty on the joint part of the glass fiber reinforced plastic and the aluminum tip to a thickness of less than or equal to 200 mu m, performing descaling, deoiling and impurity removal treatment on the aluminum tip in the post-treatment process of the aluminum tip of the blade, reserving 50mm of putty from the tip part to the direction of the blade root, performing no-batch putty and paint spraying treatment, and exposing the aluminum tip; before spraying the primer, the reserved aluminum tip with the length of 50mm is wrapped by masking paper, the masking paper is torn off after finishing spraying the finish paint and completely curing, and the aluminum tip does not need to be polished by a metal contour line. The method can improve the working efficiency, the exposed aluminum tip metal molded surface after treatment is more than that before improvement, and the integral lightning protection effect of the blade is obviously improved; the adhesion effect and the damp-heat resistant effect of the aluminum tip paint film are obviously enhanced.
Description
Technical field
The present invention relates to a kind of preparation method of wind generator set blade, particularly a kind of wind generator set blade aluminium point that is used for paints spraying method.
Background technology
Along with the efficient activity increasingly of large megawatt leaf production and large MW class blade are in the diversification of wind field running environment, also more and more higher to the production efficiency of blade, quality requirement, run blade at wind field and the postprocessing working procedures applied is painted to the aluminium point that the adaptability of environment depends on production process to a great extent, the processing mode of this operation will directly affect the running quality of blade, for increasing work efficiency, improve the carryover effect of aluminium point paint coating.Prior art makes carrying out the spraying of blade aluminium point paint, needs to carry out blade after large putty and little putty patch work all complete and to spray paint work; Aluminium cusp edge polishing work is carried out after priming paint and finish paint integral spray all complete; By the polishing of aluminium cusp edge to spilling outline line; Its spraying process complex operations, and effect is poor.
Art methods coating aluminium sheet makes experiment model (3 pieces): 1-1,1-2,1-3;
The inventive method coating aluminium sheet makes experiment model (3 pieces): 2-1,2-2,2-3;
Experimental technique: humidity resistance (1000h): temperature: 50 DEG C/humidity: 80% (GB/T 1740-2007);
Experimental result is as follows:
Draw from above humidity resistance analysis, the aluminium sheet enamelled coating adhesive force adopting the inventive method to make is obviously more excellent; Analyze adhesive force by the method for pulling open after test terminates, the inventive method adhesive force obtains maximum (7.1MPa), and average is 6MPa.
In sum, it is comparatively outstanding that 2-1 and 2-3 organizes data, and in real experiment, the observation of sheet material experimental result is also comparatively excellent, therefore after aluminium point spraying improvement, its humidity resistance and adhesive force can meet instructions for use completely.
Compared with prior art, the inventive method has the following advantages:
1. the inventive method can be increased work efficiency, and is connected a upper operation better, makes putty result more perfect;
2. the aluminium point metal profile after the inventive method process exposes than many before improvement, significantly increases blade integral and to take shelter from the thunder effect;
3. the inventive method makes the adhesion effect of aluminium point paint film and heat resistance Be very effective strengthen to the improvement that key position applies, and ensures other function admirables of aluminium point paint simultaneously.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provide a kind of method design rationally, the method that aluminium point paint coating effect is more useful, can play overall lightning protection system effect better can be made.The invention has the beneficial effects as follows, aluminium point paint coating effect can be made more useful.Because exposing of part aluminum hardware can play overall lightning protection system effect better.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is that one paints spraying method for wind generator set blade aluminium point, is characterized in, the spraying operation region of this spraying method is blade aluminium point and fiberglass join domain and the sharp overall region of blade aluminium; Before blade aluminium point putty blade coating, drying process and surface impurity cleaning process are carried out to aluminium point; At fiberglass and aluminium point junction, putty blade coating thickness≤200 μm, in the postprocessing working procedures of blade aluminium point, carry out descale to aluminium point, deoil, decontamination process, reserve 50mm and do not criticize putty with spraying paint and process, expose aluminium point from tip to blade root direction; Before spray-applied primer, wrapped up in U.S. line paper bag by aluminium point long for reserved 50mm, finish paint sprays complete and removes U.S. line paper after solidifying completely, and aluminium point does not need to carry out the polishing of metal wheel profile.
Below the wet-hot aging performance test experiments that the product adopting the inventive method to carry out sample preparation is carried out that inventor does:
Experiment sample preparation numbering:
Detailed description of the invention
Below further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, a kind of wind generator set blade aluminium point that is used for paints spraying method, and the spraying operation region of this spraying method is blade aluminium point and fiberglass join domain and blade aluminium point overall region; Before blade aluminium point putty blade coating, drying process and surface impurity cleaning process are carried out to aluminium point; At fiberglass and aluminium point junction, putty blade coating thickness≤200 μm, in the postprocessing working procedures of blade aluminium point, carry out descale to aluminium point, deoil, decontamination process, reserve 50mm and do not criticize putty with spraying paint and process, expose aluminium point from tip to blade root direction; Before spray-applied primer, wrapped up in U.S. line paper bag by aluminium point long for reserved 50mm, finish paint sprays complete and removes U.S. line paper after solidifying completely, and aluminium point does not need to carry out the polishing of metal wheel profile.
