Embodiment 1
[0020] A method for anticorrosion treatment of a photovoltaic panel frame, used for surface anticorrosion treatment of a photovoltaic panel frame, comprising sequential cleaning, drying, hot-dip galvanizing and cooling steps, the cleaning including sequential degreasing, inspection, pickling and The water washing step is characterized in that the degreasing is to use a water-based metal degreasing agent to degrease the surface of the photovoltaic panel frame; the inspection is to immerse the degreased photovoltaic panel frame in water and then remove it, and observe the surface of the photovoltaic panel frame Whether it is completely soaked by water; the pickling is to clean the photovoltaic panel frame with a pickling solution containing hydrogen chloride, hexamethylenetetramine and a corrosion inhibitor under the condition of a temperature range of 30°C-35°C, wherein , the concentration of hydrogen chloride in the cleaning solution is between 17%-22%, and the content of hexam...
Embodiment 2
[0025] This embodiment is further limited on the basis of Example 1. In order to prevent excessive precipitation of acid gas from the pickling solution during the pickling solution proportioning process and affect the composition content of the pickling solution, in the pickling step It also includes the proportioning process of the pickling solution. The proportioning process is firstly adding the corrosion inhibitor into the solvent of the pickling solution, stirring and fully dissolving, and then adding hydrogen chloride and hexamethylenetetramine.
[0026] In order to avoid excessive thermal deformation due to the rapid rise of the temperature of the photovoltaic panel during galvanizing, and at the same time cause zinc liquid to burst due to the moisture on the surface of the photovoltaic panel, the drying step is to heat the photovoltaic panel to 130°C -160℃, and the holding time is between 2-3min. With the selection of the above temperature range and holding time, the s...
