Galvanizing technology for combination intensity of galvanizing layer and base material

Abstract

The invention discloses a galvanizing technology for combination intensity of a galvanizing layer and a base material, which is used for anticorrosion processing of surface of a photovoltaic flat rack. The technology comprises the steps of cleaning, drying, galvanizing and cooling in order, and the cleaning step comprises the steps of degreasing, examining, pickling and washing in order, pickling temperature scope is between 30-35 DEG C, a pickle containing hydrogen chloride, hexamethylene tetramine and a corrosion inhibitor is used for cleaning the photovoltaic flat rack; the corrosion inhibitor contains a nitrogen compound-containing corrosion inhibitor and a sulfur compound-containing corrosion inhibitor; an assistant leaching step is provided between the drying step and galvanizing step, the assistant leaching is characterized in that the photovoltaic flat rack is immersed into a plating auxiliary for 5-8 minutes, the temperature of the plating auxiliary is between 50-57 DEG C, the plating auxiliary contains zinc chloride and ammonium chloride, the mass ratio of zinc chloride to ammonium chloride is between 1 and 4 to 1 and 10, and the plating auxiliary also contains glycerin. According to the invention, the technology route is simple, and the galvanizing layer bonding strength is good.

Description

technical field [0001] The invention relates to the field of solar power generation equipment processing, in particular to a galvanizing process that facilitates the bonding strength of a galvanized layer and a base material. 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 inst...
