Sulfamic acid

The molecular formula of sulfamic acid is NH2S03H. The commercially available product is a white powder. As long as it is kept dry and not in contact with water at room temperature, the solid sulfamic acid does not absorb moisture and is relatively stable. The aqueous solution of sulfamic acid has the same strong acidity as hydrochloric acid and sulfuric acid, so it is also called solid sulfuric acid. It has the characteristics of non-volatile, odorless and minimal toxicity to the human body. The aqueous solution of sulfamic acid has a slower effect on the corrosion products of iron. Some sodium chloride can be added to make it slowly produce hydrochloric acid, thereby effectively dissolving iron scale. The sulfamic acid 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 for cleaning galvanized metal surfaces.

sulfamic acid 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 scales on beer barrels; to clean evaporators in enamel factories, and equipment in paper mills; in air conditioning, cooling systems and evaporative condensers can be removed Rust and scale; it can be used by sea ships to remove seaweed and scale in seawater evaporators (distillation equipment), heat exchangers and salt water heaters; it can clean copper pots, radiators, tableware washing mechanisms, silverware, toilets, tiles, The scale of food and milk processing equipment; it can remove the protein deposited on the cooker and the deposits on the disinfectant used in the fresh meat, vegetable, and cheese processing plants. The U.S. Department of Agriculture has approved the use of sulfamic acid as an acid cleaning agent in fresh meat, poultry, rabbit, and egg processing enterprises.
