Technical Bulletin
Sulfamic Descalant Viscous is end point of chemicals reaction, Which is more powerfull then POWDER stage. Highly soluble in water and free from other impurities.
Sulphamic acid can be used 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.
Grades of Sulphamic acid as a descalant:
The GP grade of Sulphamic acid:
The GP grade may be used for removing scales obtained from water in heating and cooling systems e.g. boilers, heat exchangers, condensers, jackets and coils.
The SR grade of Sulphamic acid:
This formulation is recommended for scales containing high silica. Typical examples are scales found in caustic evaporators in the Aluminum industry and black liquor evaporator in the pulp industry.
The RXSOL TM grade of Sulphamic acid: SUPERIOR BLEND of Corrosion inhibitor
This formulation is recommended for removal of scales from heat exchangers made of Titanium metal. We provide Sulfamic Acid descalant that has scale solubilizing capacity and added corrosion resistance blends which offer maximum protection to metal of equipment being cleaned. Our range of Sulfamic Acid descalant is ideal for removing scales from cooling towers, boilers, heat exchangers, coilers, condensers, and various other heating and cooling systems. We also provide Sulfamic Acid descalant in self-indicating grade that changes colors to indicate that the efficiency of material has been finished.
CHEMICAL STAGE : VISOCUS LIQUID Sulfamic Acid is also known as an intermediate compound between Sulfuric Acid (H2SO4), and Sulfamide (H4N2SO2) and a dry, non-volatile, non-hygroscopic, odorless, stable acid, moderately soluble in water that forms strongly acidic aqueous solution, comparable in acidity to the common strong mineral acids.
White crystalline soild, non volatile, non volatile, non hydroscopic. Soluble in water and odorless. Toxic by ingestion.
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 SULFAMIC ACID —
• Used as an immersion liquid
• Used as filling with a Sulfamic acid descalant solution
• Used through circulation for consistent concentration though the closed circuit
• Used in cold as well as with temperature ranging from 40º to 60ºC
• Sulfamic Acid is a very safe and highly effective descalant
• Sulfamic Acid provides good cleaning and reduces manual cleaning.
• Sulfamic acid is recommended for the cooling water for descaling the condenser on running plant basis.
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.
Sulphamic acid in the Plastic industry
Sulphamic acid finds application in the plastic wherever a curing agents is required which does not have the disadvantage of inorganic acids and which acts faster than organic acids.
DIRECTION OF USAGE
• Machines should be rinsed with water to remove loose flakes & sludge's before use
• Powder should be added to warm water for an ideal solution
• Sample should be properly tested before using
• Proper ventilation is essential for effective usage of Sulfamic Acid Descalant
• After cleansing, the solution should be drained out and the system should be rinsed with water until pH value is neutral
• Rinsing with ROTO PASS – 212 for better metal prevention and passivation is recommended
