Aminosulfonic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. It is a white flake crystal in the rhombic crystal system, odorless, non volatile, non hygroscopic, and easily soluble in water and liquid ammonia. The aqueous solution is a highly ionized substance and a strong acid. Slightly soluble in methanol, insoluble in ethanol and ether. The reactivity of organic matter is weak, and its salts are easily soluble in water (except for alkaline mercury salts). When the aqueous solution boils, it hydrolyzes to ammonium sulfate. In the presence of nitrite and nitrate, nitrogen and nitrous oxide can be released according to the calculated amount to become sulfuric acid, acting as a reducing agent, and this reduction effect is particularly significant in boiling water. Aminosulfonic acid is a raw material for manufacturing synthetic sweeteners, herbicides, flame retardants, preservatives, etc. It can prevent wheat rust and can also be used as a detergent for metal and ceramic utensils. Products with a purity of over 99.9% can also be used as standard solutions for acids during alkaline titration.

For boiler systems and cooling towers, use a 10% to 15% solution circulation treatment, depending on the severity of the system. Before applying the flushing system, refill with clean water. Determine the volume of water and mix sulfamic acid in a ratio of 100 to 150 grams per liter of water. Cycle the solution at room temperature or heat it up to 60 ℃ for heavier cleaning. Attention: Do not use at the boiling point, otherwise the product may undergo hydrolysis and become ineffective. After thorough cleaning, rinse and inspect the system. For severely polluted systems, repeated applications may be necessary. After cleaning, it is necessary to regularly flush the system to remove loose scale and pollutants. Use a 10% -20% solution for rust removal.
