1, Sulfamic acid is a cleaning agent and widely used in cleaning boilers, condensers, heat exchangers, jackets and chemical pipelines.
2. The sulfamic acid solution can be injected into the carbonate reservoir. Because sulfamic acid reacts easily with reservoir rocks, it prevents salt deposition.
3. Sulfamic acid is commonly used in gold plating or alloy. The electroplating solution of gold plating, silver plating and gold-silver alloy contains 60 ~ 170 grams of sulfamic acid per liter of water.
4. Alkali metal sulfamate, ammonium sulfamate or sulfamate can be used as conductive and buffering compounds in the aqueous gold-plating bath.
