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...

Abstract

The present invention discloses a photovoltaic plate frame corrosion resistance treatment method, which is used for surface corrosion resistance treatment on a photovoltaic plate frame and sequentially comprises washing, drying, hot zinc plating, and cooling, wherein the washing step sequentially comprises degreasing, inspection, acid washing, and water washing, the degreasing step is adopting a water-based metal degreaser to carry out an oil removing treatment on the photovoltaic plate frame surface, the hot zinc plating step comprises heating a zinc liquid to a temperature of 455-480 DEG C, placing the photovoltaic plate frame into the zinc liquid, maintaining for 1-1.5 min, and taking out, the zinc liquid contains 0.07-0.1% by mass of aluminum, and the leaching assisting step is set between the drying step and the hot zinc plating step. According to the present invention, the process route is simple, and the photovoltaic plate frame surface corrosion resistance quality is easily achieved.

Description

technical field [0001] The invention relates to the field of solar power generation equipment processing, in particular to an anticorrosion treatment method for a photovoltaic panel frame. Background technique [0002] Conventional energy sources such as coal, oil, and natural gas are increasingly depleted, and there are more and more problems caused by energy shortages in the world. As a clean, pollution-free, inexhaustible energy source, solar energy has played a very important role in the utilization of new energy sources in recent years. Important role, the existing urban street lighting facilities, the solar photovoltaic panel power generation group that has begun to take shape, and even the photovoltaic panels installed on the roof of the family have made outstanding contributions to reducing the dependence of existing production and life on the coal power industry. contribute. [0003] Usually, the fixed photovoltaic panel is installed on the photovoltaic panel frame...
