Sulphamic acid is very useful products for removing scales obtained from water in heating and cooling systems e.g. boilers, condensers, heat exchangers, jackets and coils
Sulfamic Acid is a Zwitterion, a molecule with two charges that counteract each other, the Nitrogen and Oxygen have a greater pull on the bond pair of electrons due to the high electro-negativity, this causes the bond to be polar, the Nitrogen and Oxygen draw the electrons closer and become slightly negative, the Hydrogens become positive because the negative electrons are further away.

Uses: Metal and ceramic cleaning, amine sulfamates, ph control, hard water scale removal, electroplating.
At room temperatures, dilute aqueous Sulfamic Acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures. Its solution is less corrosive toward metals than other mineral acid. When compared to most of the common strong mineral acids, Sulfamic Acid has desirable water descaling properties, low volatility, low toxicity and is a water soluble solid forming soluble calcium and iron-III salts. Because of its many positive attributes like handling ease, solubility and low corrosiveness, Sulfamic Acid is used for many diversified applications.

Applications Of Sulphamic Acid:
Sulphamic acid in descaling
Sulphamic Acid is super efficient descaling agent and is used for cleaning a variety of industrial equipment and domestic appliances.
Sulphamic acid in paper & pulp Industry
Sulphamic Acid prevents pulp degradation due to temperature at the chlorination and hydrochloride stage. It permits bleaching at higher temperature and lower PH without loss of strength.
Sulphamic acid is used in manufacturing of Dyes, Pigments and in the dyeing of leather
Sulphamic Acid removes excess of nitrides used in the diazotization reactions in the manufacturing of dye stuffs and pigments. Nitrides if present in process water of effluents can also be removed by using Sulphamic Acid
Sulphamic acid in Chlorine Stabilization
Chlorine gas in water form HOCL which reacts with Sulphamic Acid form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine, Because of this, Sulphamic Acid is used for stabilizing chlorine in swimming pools and cooling towers.
Sulphamic acid in Electroplating and Electro-refining
Metal sulphamate electrolytes values for their high solubility cadmium, cobalt nickle, lead silver and radium sulphamte deposits are bright and dense. Lead sulphamate is used in refining lead when a high quality is desired.
Sulphamic acid in Sulphation and Sulphamation
Sulphamic acid is used for sulphation and sulphamation of many organic compounds. Sulphation of aklyl pheno-ethylen oxide condensation products 9for detergents and sulphation of ethoxylated phenol-formaldehyde resins is preferable with Sulphamic Acid. Stronger agents cause unwanted ring sulphomation.
