氨基磺酸在清洗液中的用量配方!
来源:http://www.jnjrh.com 日期:2019-03-01 发布人:admin
  氨基磺酸水溶液可去除铁、钢、铜、不锈钢等材质设备表面的水垢和腐蚀产物。另外,它还是唯一可用作镀锌金属表面清洗的酸。为防止氨基磺酸在高温下水解,一般控制清洗温度在60℃以下,含量在10%以下。
  Aminosulfonic acid aqueous solution can remove scale and corrosion products on the surface 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. In order to prevent hydrolysis of aminosulfonic acid at high temperature, the cleaning temperature is generally controlled below 60 C and the content is below 10%.
  氨基磺酸可单独使用,其用量需根据总的垢量来计算,一般为清洗液的5%-10%。使用时,首先用适量水溶解计算量的氨基磺酸粉末,配制成浓溶液。再在循环系统中加入约0. 3%的缓蚀剂(可用I。an-826),最后加入配制好的氨基磺酸浓溶液并循环均匀,在60℃以下循环清洗6~8h。也可以用氨基磺酸5.5% -6.5%、硫脲1%、苯并三氮唑0.1%组成的复合清洗剂。控制温度60℃,循环清洗除垢率达到95%以上。
  Aminosulfonic acid can be used alone, and its dosage should be calculated according to the total scale amount, generally 5% - 10% of the cleaning solution. When used, the calculating amount of aminosulfonic acid powder is dissolved in a proper amount of water to prepare a concentrated solution. Then, about 0.3% corrosion inhibitor (available I) is added to the circulating system. An-826), finally adding the prepared concentrated solution of aminosulfonic acid and circulating uniformly, and cleaning 6-8 hours under 60 C. Compound detergents consisting of 5.5% - 6.5%, thiourea 1% and benzotriazole 0.1% can also be used. The scale removal rate of recycling cleaning is more than 95% when the temperature is controlled at 60 C.
  由于氨基磺酸对铁氧化物的溶解能力较弱,当水垢中含有铁氧化物时,可加入少量柠檬酸制成固体复配清洗剂,其中含氨基磺酸89%、柠檬酸6%和二乙基硫脲5%。
  Because of the weak solubility of sulfamic acid to iron oxide, when scale contains iron oxide, a small amount of citric acid can be added to make solid composite cleaning agent, which contains 89% sulfamic acid, 6% citric acid and 5% diethylthiourea.
  一般的热交换器钢管内的污垢和沉淀物可以先用4%的氨基磺酸溶液浸泡30min,再加入2%的纯碱溶液清洗10min,即可完全清洗干净。
氨基磺酸
  The dirt and sediment in the general heat exchanger pipe can be soaked in 4% sulfamic acid solution for 30 minutes, then washed with 2% soda solution for 10 minutes, and then cleaned completely.
  氨基磺酸的分子式为NH2SO3H。市售商品为白色粉末,在常温下,只要保持干燥不与水接触,固体的氨基磺酸不吸湿,比较稳定。 氨基磺酸的水溶液具有与盐酸、硫酸等同等的强酸性,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点。 粉尘或溶液对眼及皮肤有刺激性,能造成灼伤。最高容许浓度10mg/m 3。眼受刺激时须用水冲洗,重者应就医诊治。皮肤接触时也应用水冲洗,再用肥皂彻底洗涤。入口时,应立即漱口,速送医院诊治。用内衬聚乙烯塑料袋的木箱包装,每箱净重25kg。贮存在阴凉、通风、干燥处。包装应密封,注意防潮。运输过程中要防雨淋和日光曝晒。对逸出物料处置时须戴好防毒面具与手套,用砂土混合扫起或用水冲洗。失火时,可用水、砂土和灭火器扑救。
  The molecular formula of aminosulfonic acid is NH2SO3H. The commercial product is white powder. At room temperature, as long as it keeps dry and does not contact with water, the solid sulfamic acid does not absorb moisture and is relatively 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. Dust or solution can irritate eyes and skin and cause burns. The maximum allowable concentration is 10 mg/m 3. When eyes are irritated, they should be washed with water. If they are serious, they should seek medical treatment. Skin contact should also be washed with water, and then thoroughly washed with soap. At the entrance, you should immediately rinse your mouth and rush to the hospital for diagnosis and treatment. Packed in wooden boxes lined with polyethylene plastic bags, each with a net weight of 25kg. Store in a cool, ventilated and dry place. Packing should be sealed and moisture-proof. Rain and sunshine should be protected during transportation. Gas masks and gloves should be worn when disposing of the escaped materials. They should be swept up with sand or washed with water. When a fire breaks out, water, sand and fire extinguishers can be used to extinguish it.
