Packing of Sulphamic acid

Sulphamic Acid is available in H.D.P.E. bags of net 50 Kgs. Material. Sample packets of 100-200 gms. are supplied on request. Feel free to send us enquiry about sulphamic acid.

Advantages of using Sulphamic Acid

  • Sulphamic Acid has very high shelf life.
  • Sulphamic acid do not require storage/handing arrangement hence no adulteration possible.
  • Sulphamic acid has very high effectivity of the descaling.
  • Complete cleaning can be chemically achieved by Sulphamic acid and does not require post descaling manual cleaning.
  • Sulphamic acid is safe acid, packed in 50 kgs HDPE bags and has no handling hazards.
  • Sulphamic acid is safe acid, packed in 50 kgs HDPE bags and has no handling hazards.
  • No storage tanks / system required for dosing.
  • The solid can be directly charged to system eliminating the cost of system reduces the leave of scaling solids and acts as anti - descalant.
  • Accidental excess dosing does not affect the metal of the circulating system but it acts to remove the deposited scale from the system.
  • It is recommended to does into the cooling water for descaling the condenser on running plant.

Applications of Sulphamic Acid

Sulphamic Acid is available in H.D.P.E. bags of net 50 Kgs. Material. Sample packets of 100-200 gms. are supplied on request. Feel free to send us enquiry about sulphamic acid.

  1. Sulphamic acid in descaling: Sulphamic Acid is super efficient descaling agent and is used for cleaning a variety of industrial equipment and domestic appliances.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.

Sulphamic acid as a descalant

  1. SThe 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.
  2. SThe 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 inthe pulp industry.
  3. The TM grade of Sulphamic acid: This formulation is recommended for removal of scales from heat exchangers made of Titanium metal.
  4. Safety: No Fumes, no hazards to equipments and personnel.
  5. Efficiency:Rapid Softening, disintegration and dissolving of scales.
  6. Economy: By reducing down-time, productivity is increased. by protecting metal and by uniform leaning of the surface equipment life is prolonged and performance made superior. The above information is adequate for commonly encountered problems of descaling.
