The molecular formula of is NH2SO3H. The commercial product is a white powder. At room temperature, as long as it is kept dry and not in contact with water, the solid  does not absorb moisture and is relatively stable. The aqueous solution of has the same strong acidity  and sulfuric acid, so it is also called solid sulfuric acid.  aqueous solution has a slow effect on the corrosion products of iron, and some sodium chloride can be added to slowly generate , thereby effectively dissolving iron scale.  aqueous solution can remove scale and corrosion products on the surface of equipment made of iron, steel, copper, stainless steel and other materials. In addition, it is the only acid that can be used to clean galvanized metal suris an important fine chemical product, widely used in a variety of industrial equipment and civil cleaning agents for metal and ceramic manufacturing, petroleum processing agents and cleaning agents, electroplating industrial agents, electrochemical polishing agents, asphalt emulsifiers, etching agents Agents, dyes, sulfonating agents for pharmaceutical and pigment industries, dyeing agents, high-efficiency bleaching agents, flame retardants for fibers, paper, softeners, resin cross-linking accelerators, herbicides, anti-withering agents and standard analytical reagents, etc. middle.

As a cleaning agentdescaling agent,  has many advantages such as convenient storage, transportation, and easy preparation because it is solid, and is especially suitable for long-distance use.
descaling agent cleaning agent has a wide range of applications and can be used to clean boilers, condensers, heat exchangers, jackets and chemical pipelines. It is used in breweries to remove glass-lined storage tanks, pots, open beer coolers, and scale layers on beer barrels; to clean evaporators in enamel factories and equipment in paper mills; in air conditioning, it can remove cooling systems and evaporative condensers. rust and scale; it can be used by sea ships to remove algae and scale in seawater evaporators (distillation equipment), heat exchangers and brine heaters; it can clean copper pots, radiators, tableware washing mechanisms, silverware, toilets, ceramic tiles, Scale of food and milk processing equipment; removes protein deposits on digesters and deposits on sterilizers used in fresh meat, vegetable and cheese processing plants. The U.S. Department of Agriculture allows
  to be used as an acid cleaning agent in fresh meat, poultry, rabbit, and egg processing enterprises.
The descaling agent solution was injected into the carbonate reservoir. Because  descaling agent   easily reacts with oil reservoir rocks, it can avoid the deposition of salts generated by the reaction, and the treatment cost is slightly higher than that of hyd, but the oil production is doubled. The United States uses potassium glycolate 48.5%, 3.4%. The 0.1-3% aqueous solution of wetting agent cleans the gypsum scale layer in the oil well casing, and the treatment time is about 30 hours
The car shell is first electroplated with tin-zinc alloy, and then painted, and the adhesion of the paint film will increase.
descaling agent  is generally used in gold plating or alloy plating. The electroplating solution of gold, silver and gold-silver alloys contains 60-170 grams of descaling agent per liter of water. A typical electroplating solution for silver-plated women's clothing needles contains 125 grams of descaling agent per liter of water, resulting in a very bright silver-plated surface. In the new aqueous gold plating solution, alkali metal sulfamate, ammonium sulfamate or descaling agent can be used as conductive and buffering compounds.
When recovering from nickel plating waste liquid, it is adsorbed with cation exchange resin and then cleaned with descaling agent, so that the adsorbed desorbed is desorbed and the resin is regenerated. For example, for the treatment of 400ppm Ni electroplating waste solution, 50ml of descaling agent  of 150g/L is used, the recovered (NH2SO3) is 2112g/L, and NiSO4 is 148g/L. Nickel-on-nickel plating is required for repairing nickel-plated parts, which can be treated with 100 g/L descaling agent during anodization. The nickel-plated surface before nickel-plating should be cleaned with 0.003-0.1 mol of descaling agent solution.
The content of descaling agent in the copper plating solution is 3 to 20 liters. The function of descaling agent  is to make the plating layer fine and ductile, and its viscosity is high.
When NH2SO3H/Ir≥7, the obtained iridium coating has no cracks, the thickness of the iridium layer is 15 microns, and the adhesive force is large. The product shows good activity in the automatic anti-pollution equipment.
When rhodium-rhenium alloy is plated on silverware and electrical components, the descaling agent in the electrophoresis solution is 100 g/L. When the thickness of the coating is ≤5 microns, it has high hardness and strong corrosion resistance, and The plating layer is very bright and beautiful.
The smooth and beautiful rhodium-rhenium electric transition layer on brass has high hardness and corrosion resistance. The electroplating solution contains 100 g/L of  50 g/L of concentrated sulfuric acid, 2 g/L of rhodium (such as sulfate), rhenium [ For example, K3N(RuCl4H2O2)2]0.05g/L, at 65ºC and 1~2A/dm2, the deposition rate is 3~4mg/Amin.
