氨基磺酸是一種硫酸的羥基被氨基取代而形成的無機固體酸，為斜方晶系白色片狀晶體，無味無臭、不揮發，不吸濕，易溶于水和液氨，水溶液是高電離物，強酸。微溶于甲醇，不溶于乙醇和乙醚。對有機物的反應性弱，它的鹽類易溶于水(堿性汞鹽例外)，水溶液煮沸時則水解成硫酸銨。在亞硝酸鹽及硝酸鹽存在下，可以按計算量分別放出氮氣、一氧化二氮而變為硫酸，起著還原劑的作用，這種還原作用在沸水中尤為顯著。氨基磺酸是制造合成甜味劑、除草劑、防火焰劑、防腐劑等的原料，可防治小麥銹病，也可用在金屬和陶瓷器皿的洗滌劑方面。純度為99.9%以上的產品在進行堿滴定時，還可作為酸的標準溶液使用。

Aminosulfonic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. It is a white flake crystal in the rhombic crystal system, odorless, non volatile, non hygroscopic, and easily soluble in water and liquid ammonia. The aqueous solution is a highly ionized substance and a strong acid. Slightly soluble in methanol, insoluble in ethanol and ether. The reactivity of organic matter is weak, and its salts are easily soluble in water (except for alkaline mercury salts). When the aqueous solution boils, it hydrolyzes to ammonium sulfate. In the presence of nitrite and nitrate, nitrogen and nitrous oxide can be released according to the calculated amount to become sulfuric acid, acting as a reducing agent, and this reduction effect is particularly significant in boiling water. Aminosulfonic acid is a raw material for manufacturing synthetic sweeteners, herbicides, flame retardants, preservatives, etc. It can prevent wheat rust and can also be used as a detergent for metal and ceramic utensils. Products with a purity of over 99.9% can also be used as standard solutions for acids during alkaline titration.

下面氫氧化鉀廠家來講講氨基磺酸的作用及用途：

Below, potassium hydroxide manufacturers will talk about the role and use of sulfamic acid:

1.氨基磺酸廣泛應用于酸性清洗劑中，如鍋爐除垢、金屬和陶瓷設備的清洗劑；熱交換器、冷卻器及發動機水冷系統的除垢劑；食品工業設備的清洗劑等；

1. Aminosulfonic acid is widely used in acidic cleaning agents, such as boiler descaling and cleaning agents for metal and ceramic equipment; Descaling agents for heat exchangers, coolers, and engine water cooling systems; Cleaning agents for food industry equipment, etc;

對于除垢設備，可使用10%的溶液。氨基磺酸對鋼、鐵、玻璃和木材設備是的，可謹慎用于銅、鋁和鍍鋅金屬表面。在浸泡罐中或通過循環清潔。對于表面，使用布或刷子涂抹在表面上，然后等待幾分鐘。必要時用刷子攪拌并用清水徹底沖洗。

For descaling equipment, a 10% solution can be used. Aminosulfonic acid is safe for steel, iron, glass, and wood equipment and can be cautiously used on copper, aluminum, and galvanized metal surfaces. In a soaking tank or through cyclic cleaning. For the surface, apply a cloth or brush to the surface and wait for a few minutes. If necessary, stir with a brush and rinse thoroughly with clean water.

對于鍋爐系統和冷卻塔，使用10%15%溶液的循環處理，具體取決于系統的嚴重程度。在應用沖洗系統之前并重新注入干凈的水。確定水的體積并以每升水100克150克的比例混合氨基磺酸。在室溫下循環溶液或加熱高60℃以進行更重的清潔。注意：請勿在沸點使用，否則產品會發生水解而不起作用。徹底清洗后沖洗并檢查系統。對于嚴重污染的系統，可能需要重復應用。清潔后需要定期沖洗系統以去除松動的水垢和污染物。使用10%-20%的溶液除銹。

For boiler systems and cooling towers, use a 10% to 15% solution circulation treatment, depending on the severity of the system. Before applying the flushing system, refill with clean water. Determine the volume of water and mix sulfamic acid in a ratio of 100 to 150 grams per liter of water. Cycle the solution at room temperature or heat it up to 60 ℃ for heavier cleaning. Attention: Do not use at the boiling point, otherwise the product may undergo hydrolysis and become ineffective. After thorough cleaning, rinse and inspect the system. For severely polluted systems, repeated applications may be necessary. After cleaning, it is necessary to regularly flush the system to remove loose scale and pollutants. Use a 10% -20% solution for rust removal.

2.造紙工業可以用作漂白助劑，可減少或漂液中重金屬離子的催化作用，從而使漂液質量得到保證，并能減少金屬離子對纖維的氧化降解作用，亦能阻止纖維的剝皮反應，提高紙漿強度、白度。

2. The papermaking industry can be used as a bleaching agent to reduce or eliminate the catalytic effect of heavy metal ions in the bleaching solution, thereby ensuring the quality of the bleaching solution and reducing the oxidative degradation of fibers by metal ions. It can also prevent the peeling reaction of fibers and improve the strength and whiteness of the pulp.

3.氨基磺酸用于制造染料、顏料和皮革染色。在染料工業中作重氮化反應過剩的亞硝酸鹽的劑、紡織品染色的定色劑。

3. Aminosulfonic acid is used in the manufacturing of dyes, pigments, and leather dyeing. In the dye industry, it is used as an elimination agent for excess nitrite in diazotization reactions and a color fixative for textile dyeing.

4.用于紡織工業，可在紡織物上形成防火層；還可用來制紡織工業的凈紗劑及其他助劑。

4. Used in the textile industry to form a fireproof layer on textile fabrics; It can also be used as a yarn cleaner and other additives in the textile industry.

5.去除瓷磚、風化和其他礦藏上多余的灌漿。用于去除瓷磚上多余的水泥漿或溶解墻壁、地板等處的風化：通過每升溫水溶解80-100克來配制氨基磺酸溶液。使用布或刷子涂抹在表面上，并讓其工作幾分鐘。必要時用刷子攪拌并用清水沖洗。請注意：如果在彩色灌漿周圍使用，請使用約2%（每升水20克）的較弱溶液，以減少從灌漿中浸出任何顏色的風險。

5. Remove excess grout from tiles, weathering, and other mineral deposits. Used to remove excess cement slurry from ceramic tiles or dissolve weathering in walls, floors, etc.: Prepare an amino sulfonic acid solution by dissolving 80-100 grams per liter of warm water. Apply a cloth or brush to the surface and let it work for a few minutes. If necessary, stir with a brush and rinse with clean water. Please note: If used around colored grout, use a weak solution of approximately 2% (20 grams per liter of water) to reduce the risk of leaching any color from the grout.

6.用于日用產品及工業表面活性劑的磺化劑。國內工業生產脂肪酸聚氧乙烯醚硫酸鈉(AES)，均使用SO3、發煙硫酸、氯磺酸等作磺化劑，使用這些磺化劑，不但設備腐蝕嚴重，生產設備復雜，投資大，而且產品色澤深。采用氨基磺酸作催化劑，生產AES，具有設備簡單，腐蝕性小，反應緩和，易于控制等特點。

6. Sulfonating agents used in daily products and industrial surfactants. Domestic industrial production of fatty acid polyoxyethylene ether sodium sulfate (AES) uses SO3, fuming sulfuric acid, chlorosulfonic acid, and other sulfonating agents. The use of these sulfonating agents not only causes severe equipment corrosion, complex production equipment, high investment, but also deep product color. The production of AES using amino sulfonic acid as a catalyst has the characteristics of simple equipment, low corrosion, mild reaction, and easy control.
