Abstract

The invention relates to the technical field of processing aluminum products, in particular to acid etching treatment liquid for acid etching treatment of aluminum alloy parts. The acid etching treatment liquid comprises the compositions of, 50 parts of phosphoric acid, 5 parts of sodium laureth sulfate, 5 parts of nitric acid, 0.5 part of crotonoside, 5 parts of aluminum, 0.5 part of diamine carbonate and 60 parts of water. The acid etching treatment liquid has novel and reasonable formula design, a small amount of the crotonoside is particularly added, the treatment efficiency of the acid etching treatment liquid can be significantly improved, and the reaction is relatively mild. Through the combination use of the acid etching treatment liquid, the stability of the aluminum alloy parts treated by the acid etching is good, and the compositions are easy to detect.

Description

Technical field [0001] The invention relates to the technical field of aluminum product processing, in particular to an acid etching treatment liquid for the acid etching treatment of aluminum alloy parts. Background technique [0002] In the aluminum product industry, acid etching treatment is an indispensable treatment process. The traditional acid etching treatment liquid and reaction are too intense, the product quality stability is poor, the F ion is not easy to detect, and the control is more difficult. Summary of the invention [0003] In view of the technical problems existing in the prior art, the purpose of the present invention is to provide an etching treatment solution for the acid etching treatment of aluminum alloy parts. In order to achieve the above purpose, the present invention adopts the following technical solutions: [0004] An acid etching treatment solution for the acid etching treatment of aluminum alloy parts, consisting of 50 parts phosphoric acid, 5 parts...
