Main uses of ammonia water:
1, for laboratory use.
Ammonia is an important reagent in the laboratory, which is mainly used as analytical reagent, neutralizer, alkaloid leaching agent, aluminum salt synthesis and weak alkaline solvent. Used for the synthesis of aluminum salts, the verification and determination of some elements, and the precipitation of hydroxides of various elements.
2. Military use.
As an alkaline disinfectant, it is used to disinfect sarin. Commonly used is 10% dilute ammonia water (density 0.960), and the concentration used in winter is 20%.
3. Industrial use.
Wool spinning, silk, printing and dyeing industries are used for washing, dissolving and adjusting pH value of wool, woolen cloth and grey cloth, and as dyeing auxiliaries. Organic industry is used as aminating agent and catalyst to produce thermosetting phenolic resin, and inorganic industry is used to prepare various iron salts.
It is used in industry for large-scale integrated circuit decompression or plasma chemical vapor deposition, and the pH regulator of boiler feed water is grown with silicon dioxide film. Ammonia water is used to neutralize carbonic acid in feed water, improve pH value and slow down the corrosion of carbon dioxide in feed water. It is also a protective agent for boiler shutdown, and it also has a good protective effect on boilers with a small amount of stored water that cannot be discharged.
