Abstract

The invention relates to the technical field of processing of petrochemical equipment plates, in particular to alkali corrosion treatment liquid for alkali corrosion treatment of an aluminum alloy petrochemical equipment plate. The alkali corrosion treatment liquid is prepared by 25 parts of sodium hydroxide, 5 parts of sodium laureth sulfate, 0.5 part of isomangiferin, 5 parts of sodium sulfide, 5 parts of glycerin and 60 parts of water. The alkali corrosion treatment liquid is novel and reasonable in formula design; in particular, a small amount of isomangiferin is added, so that the treatment efficiency of the alkali corrosion treatment liquid can be prominently improved; and the alkali corrosion treatment liquid can effectively prevent accumulation of sodium metaaluminate to generate hydrolysis and precipitation so as to obtain a high-quality delicate sanding surface.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment plate processing, in particular to an alkaline etching treatment liquid for alkaline etching treatment of aluminum alloy petrochemical equipment plates. Background technique [0002] Alkali etching treatment is an indispensable treatment process in the processing of aluminum alloy petrochemical equipment plates. The traditional alkali etching treatment is hydrolyzed and precipitated due to the accumulation of sodium metasilicate, and the pollution to the environment is relatively serious. Contents 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 alkaline etching treatment liquid for the alkaline etching treatment of aluminum alloy petrochemical equipment plates. In order to achieve the above purpose, the present invention adopts the following technical solutions: [0004] An alkaline etchi...
