In the wool textile,silk,printing and dyeing industries,it can be used for washing wool,woolenfabrics and grey cloth,dissolving and adjusting pH value,as well as a dyeing assistant,etc.
In the organic industry,it serves as an aminating agent and a catalyst for the production of thermo-setting phenolic resins;in the inorganic industry,it is used for manufacturing various iron salts.
Industrially,it is applied in reduced-pressure or plasma CVD(Chemical Vapor Deposition)oflarge-scale integrated circuits to grow silicon dioxide films.As a pH adjuster for boiler feedwater,ammonia neutralizes carbonic acid in the feed water,raises the pH value,and mitigatescorrosion caused by carbon dioxide in the feed water.Meanwhile,it also acts as a boilerlay-upprotector,exerting a good protective effect on boilers where a smallamount of residual watercannot be drained.
In the medical field,dilute ammonia solution exerts a reflex stimulant effect on respiration andcirculation,used for treating syncope and fainting,and also serves as a skin irritant and disin-fectant.It can be used as a detergent,neutralizer,and alkaloid leaching agent.Additionally,itis applied in the pharmaceutical industry,yarn cover industry,blueprinting,etc.
