氨基磺酸清洗需要注意哪些问题
来源:http://www.jnjrh.com 日期:2019-07-19 发布人:admin
  氨基磺酸及其盐类与多种金属化合物都能生成可溶性盐类。260℃时分解。溶于水、液氨,微溶于甲醇,不溶于乙醇、乙醚有机溶剂及二硫化碳、液体亚硫酸。
  Amino sulfonate and its salts and a variety of metal compounds can produce soluble salts. Decomposing at 260 degrees C. Dissolved in water, liquid ammonia, micro-soluble in methanol, insoluble in ethanol, ether organic solvents and carbon disulfide, liquid sulphate.
  其水溶液煮沸时水解为硫酸铵。有毒!不挥发也不吸湿,在常温下很稳定。能溶于水,水溶液呈酸性。在沸水中水解生成NH+4和HSO-4。
  The solution is dissolved to ammonium sulfate when it is boiled. Toxic! Do not wave nor absorb moisture, very stable at room temperature. Can be soluble in water, the solution of water is acidic. Hydrolyzed in boiling water generates NH 4 and HSO-4.
  氨基磺酸在空气中不吸湿,在室温和干燥环境下能长期保存。化学性质稳定,其水溶液有较强酸性,对金属有腐蚀作用。
  Amino sulfonate does not absorb moisture in the air and can be preserved for long periods of time at room temperature and in dry environments. The chemical properties are stable, the aqueous solution is strong lysing and corroded on the metal.
氨基磺酸
  溶解性:溶于水、液氨,微溶于乙醇和甲醇,微溶于丙酮不溶于醚。不溶于有机溶剂。易溶于含氮碱液和液氮;也可溶于含氮的有机试剂如吡啶等;难溶于乙醇和甲醇。在水中能中等程度溶解,与常见非极性溶剂如THF或甲苯等很难混合。
  Solubility: soluble in water, liquid ammonia, micro-soluble in ethanol and methanol, micro-soluble in acetone insoluble in ether. Insoluble in organic solvents. It is soluble in nitrogen-containing lye and liquid nitrogen, also soluble in nitrogen-containing organic reagents such as radon, and insoluble in ethanol and methanol. It dissolves to a moderate degree in water and is difficult to mix with common non-polar solvents such as THF or toluene.
  稳定性:稳定
  Stability: Stability
  禁配物:强氧化剂、强碱
  Prohibition: strong oxidant, strong alkali
  避免接触的条件:受热
  Conditions to avoid contact: Heat聚合危害:不聚合
  Polymerization Hazard: Non-Polymerization
  分解产物:硫氧化物、氮氧化物
  Decomposition products: sulfur oxides, nitrogen oxides
  热力设备以清洗铁的腐蚀产物,碳酸盐及磷酸盐垢为主要目的时,可以选用氨基磺酸清洗工艺。氨基磺酸清洗对金属材料有广泛的适用性、良好的除垢除锈能力,在化学清洗中越来越多的被采用。
  When the main purpose of thermal equipment is to clean corrosion products of iron, carbonate and phosphate scale, sulfamic acid cleaning process can be selected. Aminosulfonic acid cleaning has a wide range of applicability to metal materials, good ability of scale removal and rust removal, and is more and more used in chemical cleaning.
  它具有的对人体毒害性小、废水易于处理、固体形态易于运输储存等特性。那么,氨基磺酸清洗需要注意哪些问题?
  It has the characteristics of less toxicity to human body, easy treatment of wastewater and easy transportation and storage of solid form. So, what problems should be paid attention to in the cleaning of aminosulfonic acid?
  (1)氨基磺酸水随着水温的提高而增加,水溶液加热至60℃以上时,将会明显发生水解,形成硫酸盐。为了避免氨基磺酸水解,高清洗温度不宜超过70℃。
  (1) Aminosulfonic acid water increases with the increase of water temperature. When the water solution is heated to above 60 (?) C, hydrolysis will occur and sulfate will be formed. In order to avoid hydrolysis of aminosulfonic acid, the highest cleaning temperature should not exceed 70 C.
  (2)氨基磺酸去除高温氧化皮的能力有限,清洗新建锅炉应辅助添加提高去除高温氧化皮的助剂,如硫酸、氢氟酸、氟化氢铵等。
  (2) Aminosulfonic acid has limited ability to remove high-temperature oxide scales. It is necessary to add auxiliary agents to clean new boilers, such as sulphuric acid, hydrofluoric acid and ammonium hydrogen fluoride, to improve the removal of high-temperature oxide scales.
  (3)不能用于去除硅酸盐垢,清洗管道需要添加氟化物协助提高清洗能力。
  (3) It can not be used to remove silicate scale. Fluoride is added to the cleaning pipeline to help improve the cleaning ability.
  (4)氨基磺酸与其他常用酸相比,对不锈钢、铜、铝的腐蚀性相对弱一些,但是对碳钢的腐蚀性并不弱,仍然需要选用合适的缓蚀剂控制腐蚀。
  (4) Aminosulfonic acid is less corrosive to stainless steel, copper and aluminium than other commonly used acids, but not to carbon steel. It is still necessary to select appropriate inhibitors to control corrosion.
