Description

Technical Field

[0001] The utility model relates to the technical field of dezincification devices, in particular to a dezincification device for hot-dip galvanizing processing. Background Art

[0002] Hot-dip galvanizing is a metal anti-corrosion process that immerses steel in molten zinc liquid to cover the surface of the steel with a zinc layer, thereby protecting the steel from corrosion. However, in actual applications, the zinc layer sometimes falls off, which not only affects the service life of the product, but also reduces its anti-corrosion performance. Therefore, dezincification treatment is very important. The purpose of dezincification treatment is to remove the zinc layer that has fallen off or is about to fall off, restore the integrity of the coating, and improve the quality and service life of the product;

[0003] At present, some dezincification methods are to directly place steel in a chemical solution, and the zinc on the surface of the steel reacts chemically with the solution, thereby leaving the surface of the steel. However, in this way, bubbles will gather on the surface of the steel during the reaction, affecting the contact area between the steel surface and the solution, resulting in a slow reaction speed and unsatisfactory dezincification effect. Therefore, a dezincification device for hot-dip galvanizing is proposed. Utility Model Content
