Abstract
The invention discloses a preparation method of an aluminum alloy tube descaling operating fluid. The aluminum alloy tube descaling operating fluid is prepared by mixing raw materials comprising 65-72wt% of water, 0.3-0.8wt% of citric acid, 0.5-1.5wt% of anhydrous sodium carbonate, 2-7wt% of triethanolamine, 2-7wt% of fatty alcohol polyoxyethylene ether, 2-7wt% of alkylphenol polyoxyethylene, 0.2-0.9wt% of hexamethylenetetramine, 0.5-1.2wt% of nitric acid, 6-10wt% of tartaric acid, 1-3wt% of trisodium phosphate, 2-5wt% of ethanol, and the balance hydrofluoric acid at normal temperature. The aluminum alloy tube descaling operating fluid has the advantages of simple operation, no heating, good cleaning effect, no corrosion to the surface of an aluminum alloy tube, glossiness maintenance, repeated use, no damages to skins, low carbon, environmental protection and cost saving.
Description
Technical field
The present invention relates to chemical cleaning technique field, especially a kind of preparation method who is applicable to aluminium-alloy pipe scale removal working fluid.
Background technology
At present, in order to remove the dirt of aluminium-alloy pipe, traditional cleaning agent formula is for heating to 90 ℃-95 ℃ after the 5:4:3:8 mixing by mass percentage of nitric acid, hydrofluoric acid, hydrochloric acid and water, aluminium alloy to be cleaned soak 4-4.5 hour ability process clean, 8 hours can only cleaning aluminum alloy pipe 40-45 ton, efficiency is not high, and because nitric acid, hydrofluoric acid and hydrochloric acid are through heating generation acid mist, human body is had to great harm, severe contamination air, the discharge of waste acid water is severe contamination water resources also.

(12), throw in while stirring the hydrofluoric acid that weight percent is surplus;
(13), after whole feeding in raw material, stir again and within 20-30 minute, be finished product;
The weight percent of wherein said nitric acid is 25%.
Further, the preparation method of described aluminium-alloy pipe scale removal working fluid, has following steps:
(1), under normal temperature, in stirrer, adding weight percent is 68.9% water;
(2), throwing in while stirring weight percent is 0.5% citric acid;
(3), throwing in while stirring weight percent is 1% anhydrous sodium carbonate;
(4), throwing in while stirring weight percent is 5% trolamine;
(5), throwing in while stirring weight percent is 5% fatty alcohol-polyoxyethylene ether;
(6), throwing in while stirring weight percent is 3% alkylphenol polyoxyethylene;
(7), throw in while stirring the vulkacit H that weight percent is 0.6%-1.2%;
(8), throwing in while stirring weight percent is the acid of 1% pin;
(9), throwing in while stirring weight percent is 8% tartrate;
(10), throwing in while stirring weight percent is 2% tertiary sodium phosphate;
(11), throwing in while stirring weight percent is 3% ethanol;
(12), throwing in while stirring weight percent is 2% hydrofluoric acid;
(13), after whole feeding in raw material, stir again and within 20-30 minute, be finished product;
