Galvanizing technology good for uniformity of galvanizing layer thickness

Abstract

The invention discloses a galvanizing technology good for uniformity of galvanizing layer thickness, which is used for anticorrosion processing on the surface of a photovoltaic flat rack. The technology comprises the steps of cleaning, drying, galvanizing and cooling in order, and the cleaning comprise comprises the steps of degreasing, examining, pickling and washing in order, the degreasing step employs a water-based metal degreasing agent for removing oil on the surface of the photovoltaic flat rack, the pickling step is characterized in that when the temperature scope is between 30-35 DEG C, a pickle containing hydrogen chloride, hexamethylene tetramine and corrosion inhibitor are employed for washing the photovoltaic flat rack; the corrosion inhibitor contains a nitrogen compound-containing corrosion inhibitor and a sulfur compound-containing corrosion inhibitor; the galvanizing step is characterized in that zinc liquid is heated to 455-480 DEG C, the photovoltaic flat rack is placed in the zinc liquid for keeping for 1-1.5 minutes and then is taken out, and the zinc liquid contains aluminium. The galvanizing technology has simple process, and a galvanizing layer with better combination quality, thickness quality and uniformity quality can be conveniently obtained.

Description

technical field [0001] The invention relates to the field of solar power generation equipment processing, in particular to a galvanizing process that is beneficial to the uniformity of the thickness of the galvanized layer. 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 instal...
