氨基磺酸是一种硫酸的羟基被氨基取代而形成的无机固体酸,为斜方晶系白色片状晶体,无味无臭、不挥发,不吸湿,易溶于水和液氨,水溶液是高电离物,强酸。微溶于甲醇,不溶于乙醇和乙醚。对有机物的反应性弱,它的盐类易溶于水(碱性汞盐例外),水溶液煮沸时则水解成硫酸铵。在亚硝酸盐及硝酸盐存在下,可以按计算量分别放出氮气、一氧化二氮而变为硫酸,起着还原剂的作用,这种还原作用在沸水中尤为显著。氨基磺酸是制造合成甜味剂、除草剂、防火焰剂、防腐剂等的原料,可防治小麦锈病,也可用在金属和陶瓷器皿的洗涤剂方面。纯度为99.9%以上的产品在进行碱滴定时,还可作为酸的标准溶液使用。
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.
Below, potassium hydroxide manufacturers will talk about the role and use of sulfamic acid:

对于除垢设备,可使用10%的溶液。氨基磺酸对钢、铁、玻璃和木材设备是的,可谨慎用于铜、铝和镀锌金属表面。在浸泡罐中或通过循环清洁。对于表面,使用布或刷子涂抹在表面上,然后等待几分钟。必要时用刷子搅拌并用清水彻底冲洗。
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.
对于锅炉系统和冷却塔,使用10%15%溶液的循环处理,具体取决于系统的严重程度。在应用冲洗系统之前并重新注入干净的水。确定水的体积并以每升水100克150克的比例混合氨基磺酸。在室温下循环溶液或加热高60℃以进行更重的清洁。注意:请勿在沸点使用,否则产品会发生水解而不起作用。彻底清洗后冲洗并检查系统。对于严重污染的系统,可能需要重复应用。清洁后需要定期冲洗系统以去除松动的水垢和污染物。使用10%-20%的溶液除锈。
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.造纸工业可以用作漂白助剂,可减少或漂液中重金属离子的催化作用,从而使漂液质量得到保证,并能减少金属离子对纤维的氧化降解作用,亦能阻止纤维的剥皮反应,提高纸浆强度、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、颜料和皮革染色。在染料工业中作重氮化反应过剩的亚硝酸盐的剂、纺织品染色的定色剂。
