Abstract

The invention relates to the technical field of aluminum profile machining, in particular to alkali corrosion treatment fluid for alkali corrosion treatment of an aluminum profile. The alkali corrosion treatment fluid is prepared from 30 parts of sodium hydroxide, 5 parts of polyvinyl acetate emulsion, 0.5 part of gastrodin, 5 parts of sodium sulphide, 5 parts of sodium carbonate, 5 parts of sorbitol and 50 parts of water. The alkali corrosion treatment fluid is novel and reasonable in compound design, especially a small amount of gastrodin is added, and therefore the treatment efficiency of the alkali corrosion treatment fluid can be remarkably improved, and the situation that hydrolysis and sediment happen due to accumulation of sodium metaaluminate can be effectively avoided so that a high-quality fine sand surface can be obtained.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to an alkaline etching treatment liquid for alkaline etching treatment of aluminum profiles. Background technique [0002] In the processing of aluminum profiles, alkali etching treatment is an indispensable treatment process and a key step to obtain a good surface for it. Due to the accumulation of sodium metasilicate, the traditional alkali etching treatment undergoes hydrolysis and precipitation, and the pollution to the environment is relatively serious. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide a kind of alkaline etching treatment solution for the alkaline etching treatment of aluminum profiles. In order to achieve the above object, the present invention adopts the following technical solutions: [0004] An alkaline etching treatment solution for alkalin...
