Abstract

The invention relates to the technical field of processing of petrochemical equipment plates, in particular to a preparation method of alkali corrosion treatment liquid for alkali corrosion treatment of an aluminum alloy petrochemical equipment plate. Firstly, 5 parts of sodium laureth sulfate and 20 parts of water are added in a container for stirring by 5 minutes; then, 25 parts of sodium hydroxide and 10 parts of water are slowly added when stirring, and are stirred by 5 minutes after adding; 0.5 part of isomangiferin and 5 parts of glycerin are slowly added when stirring, and are stirred by 5 minutes after adding; and finally, 5 parts of sodium sulfide and 30 parts of water are added for stirring by 10 minutes. The preparation method of the alkali corrosion treatment liquid not only can improve the dissolving property of all substances, but also can prevent the possibility of particle agglomeration through a gradual adding method and reasonable design of the material adding sequence, so that the surface protection function of the alkali corrosion treatment liquid is prominently promoted.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment plate processing, in particular to a method for preparing 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.
