Embodiment Construction

[0045] Next, use Figure 1 to Figure 4 , the electrogalvanizing apparatus 1 and the electrogalvanizing method according to the embodiment of the present invention will be described.

[0046] The electrogalvanizing apparatus 1 (electrogalvanizing method) performs a process of forming a galvanized film on the surface of an object to be plated. In the electrogalvanizing apparatus 1 (electrogalvanizing method), as the process of forming a galvanized film on the surface of the object to be plated, it is not limited to the process of forming a galvanized film on the surface of the object to be plated with zinc, It also includes a process of forming a galvanized film (a galvanized film) on the surface of a plated article using a zinc alloy.

[0047] The object to be plated is a predetermined member made of a metal material including iron. The article to be plated to form a galvanized film by the electrogalvanizing apparatus 1 includes architectural metal parts (eg, metal screws for...

Abstract

The present invention provides an electrogalvanizing apparatus and an electrogalvanizing method, capable of drastically reducing the amount of water used for water washing of a plated product. The electrogalvanizing apparatus (1) performs a process of forming a galvanized coating on the surface of an object to be plated, and comprises a pretreatment portion (2) for performing degreasing treatmentand substrate adjustment on the surface of the object to be plated; and plating treatment part (3) for carrying out plating process after the object to be plated is subjected to the degreasing treatment and the substrate adjustment. The pretreatment portion (2) sprays a grinding agent to the surface of the object to be plated to conduct the substrate adjustment on the surface of the object to be plated.

Description

technical field [0001] The present invention relates to the technology of an electrogalvanizing device and an electrogalvanizing method for forming a galvanized film on the surface of an object to be plated. Background technique [0002] Conventionally, technologies related to an electrogalvanizing apparatus and an electrogalvanizing method for forming a galvanized film or a galvanized alloy film on the surface of an object to be plated are known (see Patent Document 1). [0003] The electrogalvanizing apparatus includes a pretreatment unit and a plating treatment unit. [0004] In the above electrogalvanizing apparatus, the pretreatment section performs treatment (degreasing treatment) to remove grease on the surface of the plated article by alkaline degreasing, etc. Treatment of oxides on the surface of dressings (base adjustment), etc. [0005] In addition, in the above-mentioned electrogalvanizing apparatus, the plating treatment part is constituted by, for example, a ...
