氨基磺酸清洗剂的应用!
来源:http://www.jnjrh.com 日期:2019-01-26 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%.
  氨基磺酸单独使用时,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),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。
  When sulfamic acid is used alone, 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.
氨基磺酸
  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。
  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.
