  氨基磺酸的分子式为NH2SO3H。市售商品为白色粉末,在常温下,只需坚持枯燥不与水接触,固体的氨基磺酸不吸湿,比拟稳定。 氨基磺酸的水溶液具有与盐酸、硫酸同等等的强酸性,故别名又叫固体硫酸,它具有不挥发、无臭味和对人体毒性极小的特性。 氨基磺酸水溶液对铁等金属的腐蚀作用较慢,可添加一些氯化钠,使之相当于转化为盐酸,从而有效地溶解铁垢。 氨基磺酸水溶液可去除铁、钢、铜、不锈钢等资料制造的设备外表的水垢和腐蚀产物。另外,它还是独一可用作镀锌金属外表清洗的酸。当与水配比成1:4时。能够腐蚀蛋壳(碳酸钙和碳酸镁)。
  The molecular formula of aminosulfonic acid is NH2SO3H. Commercial products are white powder. At room temperature, only insist on dryness without contact with water, solid sulfamic acid does not absorb moisture and is comparatively stable. Aminosulfonic acid aqueous solution 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 human body. The corrosion of sulfamic acid solution to iron and other metals is slow. Some sodium chloride can be added to make it equivalent to hydrochloric acid, thus effectively dissolving iron scale. Aminosulfonic acid aqueous solution can remove scale and corrosion products on the surface of equipment made of iron, steel, copper and stainless steel. In addition, it is the only acid that can be used for cleaning the surface of galvanized metal. When the ratio of water to water is 1:4. It can corrode eggshells (calcium carbonate and magnesium carbonate).
  将氨基磺酸溶液注入碳酸盐岩产油层。由于氨基磺酸容易和油层岩石起反响,能防止反响生成盐的堆积,处置费用比用盐酸略高些,但石油产量倍增。美国用羟基乙酸钾48.5%,氨基磺酸3.4%。润湿剂0.1—3%的水溶液清洗油井套管中的石膏垢层,处置时间约30小时
  Aminosulfonic acid solution is injected into carbonate reservoir. Because sulfamic acid is easy to react with reservoir rocks, it can prevent the accumulation of salt generated by reactions. The cost of disposal is slightly higher than that of hydrochloric acid, but the oil production is doubled. Potassium glycoacetate 48.5% and aminosulfonic acid 3.4% were used in the United States. The wetting agent 0.1-3% water solution cleans the gypsum scale layer in the casing of oil well, and the disposal time is about 30 hours.
  汽车外壳先电镀锡-锌合金,然后上漆,漆膜的粘接力就会增加。
  Tin-zinc alloy is plated on the automobile shell, and then coated, the adhesion of the paint film will increase.
  镀金或合金时普遍采用氨基磺酸,镀金、银、金-银合金的电镀液是每立升水中含氨基磺酸60~170克。镀银女服饰针的典型电镀液是每立升水中含氨基磺酸125克,可取得外表十分光亮的镀银。在新的含水镀金电镀液中碱金属氨基磺酸盐、氨基磺酸铵或氨基磺酸可作为导电、缓冲作用的化合物运用。
  Aminosulfonic acid is commonly used in gold plating or alloy plating. The bath of gold plating, silver plating and gold-silver alloy plating contains 60-170 grams of amino sulfonic acid per liter of water. The typical electroplating solution for silver-plated women's clothing needles is 125g aminosulfonic acid per liter of water, which can obtain very bright silver plating. Alkali metal sulfamate, ammonium sulfamate or sulfamate can be used as conductive and buffer compounds in new aqueous gold plating bath.
  从镀镍废液中回收时是用阳离子交流树脂吸附处置然后用氨基磺酸清洗树脂,使被吸附的解吸出来,树脂取得再生。例如处置400ppmNi的电镀废液,用150克/升的氨基磺酸50ml,回收的(NH2SO3)2112克/升,NiSO4148克/升。在镀镍部件修复时需求镍上镀镍,在其阳极处置时可用100克/升的氨基磺酸处置。在镀镍前的镀镍外表要用0.003~0.1克分子的氨基磺酸溶液清洗。
氨基磺酸
  When recovering from nickel plating wastewater, the resin is adsorbed and disposed by cation exchange resin, then cleaned by Aminosulfonic acid, so that the adsorbed resin can be desorbed, and the resin can be regenerated. For example, 400 ppmNi electroplating waste solution is disposed of with 150 g/l sulfamic acid 50ml, 2112 g/l of recovered (NH2SO3) and 4148 g/l of NiSO. Nickel plating is required for repairing nickel-plated parts and 100g/L sulfamic acid is used for anodic disposal. The appearance of nickel plating before nickel plating should be cleaned with 0.003-0.1 g molecule sulfamic acid solution.
  镀铜液的氨基磺酸含量为3~20升,氨基磺酸的作用是使镀层细密而富有延展性,其粘度力高。
  The content of sulfamic acid in copper plating bath is 3 to 20 liters. The function of sulfamic acid is to make the coating fine and ductile, and its viscosity is high.
  镀铱时NH2SO3H/Ir≥7,取得的铱镀层无裂纹,铱层厚15微米,粘接力大,该产品有自动抗污染设备中显现出良好的活性。
  NH2SO3H/Ir (> 7) when Iridium plating, the obtained Iridium coating has no cracks, the thickness of Iridium layer is 15 microns, and the adhesive force is large. The product has good activity in automatic anti-pollution equipment.
