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
The present invention relates to petrochemical equipment plate processing technique field, specifically relate to a kind of preparation method of aluminum alloy material petrochemical equipment sheet material alkaline etching process alkaline etching treatment solution.
Background technology
In the course of processing of the petrochemical equipment plate of aluminum alloy material, alkaline etching process is absolutely necessary treatment process, and traditional alkaline etching process occurs be hydrolyzed and precipitate due to the accumulative of Starso, and comparatively serious to the pollution of environment.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of preparation method of aluminum alloy material petrochemical equipment sheet material alkaline etching process alkaline etching treatment solution, for achieving the above object, present invention employs following technical scheme:
A preparation method for aluminum alloy material petrochemical equipment sheet material alkaline etching process alkaline etching treatment solution, first adds 5 parts of laureth sodium sulfovinates and 20 parts of water, stirs 5 minutes in container; Then slowly add 25 parts of sodium hydroxide and 10 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of Isomangiferin and 5 parts of glycerol, limit edged stirs, and stirs 5 minutes after interpolation; Finally slowly add 5 parts of sodium sulphite and 30 parts of water, stir 10 minutes.
Beneficial effect of the present invention shows:
1) the alkaline etching treatment solution, used in alkaline etching treatment process, its formulating of recipe is novel, reasonable, particularly with the addition of a small amount of Isomangiferin, the processing efficiency of alkaline etching treatment solution can be significantly improved, it effectively can prevent the accumulative of sodium metaaluminate and occur be hydrolyzed and precipitate, to obtain high-quality careful sand face.
2), the preparation method of alkaline etching treatment solution, by the method for progressively adding and appropriate design order of addition(of ingredients), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, the surface protecting function of alkaline etching treatment solution is promoted significantly.
3), the aluminum alloy material petrochemical equipment sheet material alkaline etching process preparation method of alkaline etching treatment solution, operating procedure is more succinct, by formula and the preparation method of appropriate design alkaline etching treatment solution, thus improve aluminum alloy material petrochemical equipment sheet material alkaline etching treatment effect and quality.
