The molecular formula of amino sulfonic acid is NH2SO3H. Commercially available product is white powder, at room temperature, as long as the drying is not in contact with water, solid amino sulfonic acid does not absorb moisture, more stable. The aqueous solution of amino sulfonic acid has the same strong acid with hydrochloric acid and sulfuric acid, so it is also called solid sulfuric acid. It has the characteristics of no volatilization, no smell and little toxic to the human body. The corrosion action of the aqueous solution of amino sulfonic acid on iron and other metals is slow, can add some sodium chloride, which is equivalent to the conversion of hydrochloric acid, so as to effectively dissolve the iron scale. Sulfamic acid aqueous solution can scale and corrosion products manufacturing equipment surface material removal iron, steel, copper, stainless steel. In addition, it is the only acid can be used as a galvanized metal surface cleaning. When the ratio of water to 1:4. Can be corroded eggshell (calcium carbonate and magnesium carbonate).
