English name: Sulfamic acid
CAS number: 5329-14-6
At normal temperature, as long as it is kept dry and not in contact with water, the solid sulfamic acid is not hygroscopic and is relatively stable. The aqueous solution of sulfamic acid has strong acidity equivalent to hydrochloric acid and sulfuric acid, so the name is also called solid sulfuric acid, which has the characteristics of non-volatile, no odor and extremely low toxicity to human body. Dust or solution is irritating to the eyes and skin and can cause burns.
As a cleaning agent, sulfamic acid is a solid, has many advantages such as convenient storage and transportation, easy to prepare, and is especially suitable for long-distance use.
Sulfamic acid cleaners are used in a wide range of applications for cleaning boilers, condensers, heat exchangers, jackets and chemical piping. It is used in the brewery to remove glass-lined tanks, pots, open beer coolers, scale layers on beer barrels, evaporators for cleaning enamel plants, and equipment for paper mills; cooling systems, evaporative condensers for air conditioning Rust and scale; the sea wheel can be used to remove seawater vaporizers (distillation equipment), seaweed and scale in heat exchangers and brine heaters; copper pots, radiators, dishwashing mechanisms, silverware, toilets, tiles, Scale of food and milk processing equipment; it can remove proteins deposited on the digester as well as sediments on the disinfection used in fresh meat, vegetables, and cheese processing plants. The US Department of Agriculture has approved the use of sulfamic acid as an acid cleaner in fresh meat, poultry, rabbits, and egg processing companies.
