Embodiment 1

[0048] In this example, the copper row is a copper row for a long straight structure as an example, which is painted, and its specifications are 1000 mm long, width 100 mm, thick 10mm, such as figure 2 As shown, there is a mounting area in a range of 100 m in both ends, and no spraying, the intermediate shaded area is a spray region.

[0049] Specific painted process, including the following steps:

[0050] S1, copper surface defect grinding:

[0051] Scrubbing the copper row surface with pneumatic grinding tools and 600 # sandpaper, then scratched with a scratch, then polished

[0052] S2, pickling treatment:

[0053] The copper rod treated after step S1 was soaked in the acid wash for 12min, and then removed, washed out, washed in the water, and then dried under 40 ° C, the drying time was 20 min; the ingredient of the pickling liquid The ratio is: 0.25% wt carboxylate, 0.015% wt N-alkyl-N-acyl glucamine, 1.3% wt phosphoric acid, 0.15% WT nitric acid, margin;

[0054] S3, passiv...

Embodiment 2

[0065] In this example, the copper row is a copper row of the complex bend as an example, which is painted, and its specification is (calculated according to the projection and view) total length 1500mm, the total width is 1000mm, the total height is 100mm, such as image 3 As shown, each of the two ends is in the mounting area within 200 m ranges, no spraying, the intermediate shaded area is a spray region.

[0066] Specific painted process, including the following steps:

[0067] S1, copper surface defect grinding:

[0068] With pneumatic grinding tools, 200 # sandpaper is placed, and then polished with scouring cloth;

[0069] S2, pickling treatment:

[0070] The copper rosewhatted after step S1 is soaked in the acid washing solution for 5 min, and then remove it. After cleaning in water, then dry under water, then drying at 30 ° C, drying time is 10 min; acid wash ingredient The ratio is: 0.05% wt carboxylate, 0.01% wt N-alkyl-N-acyl glucamine, 0.6% WT phosphoric acid, 0.1% WT ...

Embodiment 3

[0082] In this example, the copper row is a copper row of a copper row that has been soldered by multiple welding, which is painted, and its specification is (calculated according to the vocative view) total length 2400mm, a total width of 1200mm, a total height 30mm, such as Figure 4 As shown, it is a mounting area in the 50 mm range of 50 mm per welded tip, and all shaded areas are spray regions.

[0083] Specific painted process, including the following steps:

[0084] S1, copper surface defect grinding:

[0085] Pneumatic grinding tools carry 800 # sandpaper sanding copper surface all scratches, bruises, then polish, then polish with scouring cloth, then use stainless steel wire to brush, put all welds out of metal gloss;

[0086] S2, pickling treatment:

[0087] The copper rod treated after step S1 is soaked in the acid washing for 20 min, and then remove it. After cleaning in water, then dry under 50 ° C, drying time is 30 min; acid washing The ratio is: 0.5% wt carboxylate,...

Abstract

The invention discloses a copper bar paint spraying process for a wind generating set. The copper bar paint spraying process comprises the following steps that S1, surface defects of a copper bar are polished; S2, acid pickling treatment is carried out; S3, passivating treatment is carried out; S4, the coating is blended; S5, spraying is carried out; S6, a paint film is dried and cured; and S7, the quality of the paint film is detected. The copper bar paint spraying process has no specific requirements on the structure, specification and size of the copper bar, and the range of applicable objects is wide; according to the invention, the formulas of a pickling solution, a passivation solution and the coating in the prior art are improved and adjusted to a certain extent, so that the oxidation phenomenon on the surface of the copper bar is effectively prevented, the comprehensive performance of the coating is improved, and the first-pass yield of the product is improved; and according to the copper bar paint spraying process, the bare copper bar made of the same material as the sprayed copper bar is adopted as a base material for calibration or zero calibration of a coating thickness gauge, so that the measurement error is effectively eliminated, and the measurement value is closer to the true value.

Description

Technical field [0001] The present invention relates to the field of copper row processing and manufacturing, and in particular to a copper spray process for wind turbine. Background technique [0002] According to "30 carbon peaks, 60 carbon neutral" goals, 2030 wind power, photovoltaic power generation accumulated installed installed 12 billion kilowatts, wind power, photovoltaic industries, will usher in a new round of outbreak growth. Wind turbines is one of the core devices of a wind power system. The wind turbines use copper rows, mounted on the generator set, and works on electricity, conventional. [0003] The wind turbine is used for copper rows. Before formal assembly and installation, it needs to do multi-way insulation, in which the first road is to spray a layer of anti-static, anti-oxidation, anti-fingerprint coating on the copper row surface. [0004] At present, in the prior art, common treatment methods are sprayed after surface grinding, but after the surface of...
