氢氧化钾溶液能腐蚀哪些材料?

发布来源:http://www.jinhao360.com    更新时间:2020-04-30 点击数:

  众所周知氢氧化钾具有极强的腐蚀性,并且其化学性质与烧碱相似,能引起灼伤,吸入后强烈刺激呼吸道或造成灼伤。皮肤和眼直接接触可引起灼伤;口服灼伤消化道,可致死。但是除了对人体皮肤会造成腐蚀性外还能腐蚀哪些材料。

  It is well known that potassium hydroxide is highly corrosive, and its chemical properties are similar to those of caustic soda, which can cause burns. After inhalation, it can strongly stimulate the respiratory tract or cause burns. Direct contact of skin and eyes can cause burns; oral burn of digestive tract can cause death. But what materials can corrode besides corrosiveness to human skin.
  首先我们可以排除掉氢氧化钾溶液不能腐蚀的材料,根据HG/T20667-1990相关表示,氢氧化钾的储罐应用橡胶做内衬,所以它并不会腐蚀这些材料,如:天然硬胶,天然软胶,丁苯胶,氯丁胶,丁基胶等;
  First of all, we can exclude the materials that cannot be corroded by potassium hydroxide solution. According to Hg / t20667-1990, the tank of potassium hydroxide should be lined with rubber, so it will not corrode these materials, such as natural hard rubber, natural soft rubber, styrene butadiene rubber, neoprene, butyl rubber, etc;
  其次根据相对的资料显示氢氧化钾与金属铝会发生反应,其反应式如下:
  Secondly, according to the relative data, potassium hydroxide will react with aluminum, and the reaction formula is as follows:
氢氧化钾
  如与铝反应:2Al+2KOH+2H2O=2KAlO2+3H2↑
  Such as reaction with aluminum: 2Al + 2koh + 2H2O = 2kalo2 + 3h2 ↑
  如与氧化铝反应:Al2O3+2KOH=2KAlO2+H2O
  Such as reaction with alumina: Al2O3 + 2koh = 2kalo2 + H2O
  所以氢氧化钾溶液在储存配送时应注意不要使用这些材料,并且要储存在阴凉、干燥、通风良好的库房。远离火种、热源。库内湿度最好不大于85%。包装必须密封,切勿受潮。应与易(可)燃物、酸类等分开存放,切忌混储。储区应备有合适的材料收容泄漏物。
  Therefore, the potassium hydroxide solution should not use these materials in storage and distribution, and should be stored in a cool, dry, well ventilated warehouse. Keep away from fire and heat. The humidity in the warehouse should be no more than 85%. The package must be sealed from moisture. It shall be stored separately from inflammable (inflammable) substances and acids, and mixed storage shall be avoided. The storage area shall be equipped with appropriate materials to contain the leakage.
