Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in the above-mentioned partial gold plating process, it is necessary to use a clamp to fix the aluminum material, and then the shielding material can be wrapped on the area that needs to be gold-plated on the aluminum material, and the unwrapped shielding material can be wrapped with a gold-returning mixture. The gold-plated layer of the part needs to be removed, and finally the shielding material needs to be removed again. This operation is cumbersome and has certain limitations for mass production.

Embodiment Construction

[0034] The following is attached figure 1 The application is described in further detail.

[0035] The embodiment of the present application discloses a partial gold plating process. refer to figure 1 , the local gold plating process includes the following steps:

[0036] S100: Product surface pretreatment, including degreasing and pickling on the product surface in sequence.

[0037] S110: degreasing.

[0038] S111: The product is immersed in an 80° degreasing solution, where the degreasing solvent includes degreasing agent and hot water with a mixing ratio of 1:20. Degreasers include sodium silicate, trisodium phosphate, polyethylene glycol octylphenyl ether, sodium sulfonate and sodium carbonate in a mixing ratio of 11:11:2:1:8.

[0039] According to the degree of oil pollution on the surface of the product, the method of wiping and decontamination can be used together with the degreasing solvent for degreasing work.

[0040] S112: After degreasing the surface of the ...

Abstract

The invention relates to a local gold plating process, and belongs to the field of gold plating. The local gold plating process comprises the following steps: S100, product surface pretreatment: oil removal and acid pickling; S200, nickel plating, forming a nickel layer on the surface of a product; S300, performing glue plating; S400, local glue removal; S500, gold plating, specifically performing gold plating on the glue layer removal part; and S600, removing the glue layer. The method has the effect of improving the local gold plating efficiency.

Description

technical field [0001] The present application relates to the field of gold plating, in particular to a partial gold plating process. Background technique [0002] The gold plating process is to attach gold to the surface of metal or non-metal objects by electrolysis or chemical methods to form a thin layer of gold. Therefore, the gold plating process can be divided into two categories according to the gold plating method: chemical gold plating and electroplating gold. In addition, according to the size of the gold-plated area, it can be divided into: overall gold-plated and partial gold-plated. [0003] The Chinese patent with the publication number CN112126929A discloses a partial gold plating process on the surface of an aluminum material, which includes the following steps: removing impurities on the surface of the aluminum material; immersing the aluminum material treated in step A in a zinc dipping solution to react until the aluminum After forming a galvanized layer ...
