Acid Sulfamic introduction

The molecular formula of Sulfamic acid is NH2SO3H . Commercially available for white powder, at room temperature, as long as the drying does not contact with water, solid acid Sulfamic does not absorb moisture, more stable. Acid Sulfamic solution with hydrochloric acid, sulfuric acid and other equivalent strong acid, so the name is also called solid sulfuric acid, it has no volatile, no smell and the characteristics of human toxicity is very small. Acid Sulfamic aqueous solution of iron and other metals corrosion slower, you can add some sodium chloride, which is equivalent to the conversion of hydrochloric acid, so as to effectively dissolve the iron scale. Sulfamic acid 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)
