固体氢氧化钾可做除油剂!

发布来源:http://www.jinhao360.com    更新时间:2019-02-22 点击数:

  氢氧化钾用途非常广泛,它应用在不同的行业,不管应用在哪一行业它的作用都非常大,今天我们就来讲解一下固体氢氧化钾可做除油剂。

  Potassium hydroxide is widely used in different industries. It plays a very important role in any industry. Today we will explain that solid potassium hydroxide can be used as degreaser.
  固体氢氧化钾是常用的除油剂之一,其与动植物油中的硬脂酸产生皂化反应,生成水溶性的硬脂酸钠(肥皂)和丙三醇(甘油)。当氢氧化钾浓度太低,pH∠10.5时,硬脂酸钠发生水解,除油效果降低;浓度太高,会使硬脂酸钠和表面活性剂的溶解度降低,使水洗性变差,除油后不易洗净。故固体氢氧化钾的用量一般不超过100g/L,通常都在50g/L~70g/L之间。
  Solid potassium hydroxide is one of the commonly used deoilers. It reacts with stearic acid in animal and vegetable oils to produce water-soluble sodium stearate (soap) and glycerol (glycerol). When the concentration of potassium hydroxide is too low and the pH is 10.5, sodium stearate hydrolyzes and the oil removal effect decreases; if the concentration is too high, the solubility of sodium stearate and surfactant will be reduced, and the washability will be worse, and it will not be easy to clean after oil removal. Therefore, the amount of solid potassium hydroxide generally does not exceed 100g/L, usually between 50g/L and 70g/L.
  使用固体氢氧化钾制造的除油液适用于钢铁、铜及铜合金、铝及铝合金的除油(铝及铝合金除油时间应严格控制在1分钟之内,以免遭受腐蚀)。固体氢氧化钾是强腐蚀剂,使用时要穿戴好防护用品,注意安全,含有氢氧化钾的除油废水应经过中和处理后才能排放。
  The degreasing liquid made of solid potassium hydroxide is suitable for degreasing of steel, copper and copper alloys, aluminum and aluminum alloys (the degreasing time of aluminum and aluminum alloys should be strictly controlled within 1 minute to avoid corrosion). Solid potassium hydroxide is a strong corrosive agent. Protective articles should be worn well and safety should be paid attention to when using. Oil removal wastewater containing potassium hydroxide should be neutralized before discharging.
  另外氢氧化钾适用于各种活性染料,对各种结构的活性染料都有较高的给色量和重现性;适用于各种设备,尤其在低浴比和气雾染色机上显示其独特的优越性。在筒子纱的生产上能有效解决内外层层差。
  In addition, potassium hydroxide is suitable for all kinds of reactive dyes. It has high color feeding and reproducibility for all kinds of reactive dyes. It is suitable for all kinds of equipment, especially in low bath ratio and aerosol dyeing machine. The difference between inner and outer layers can be effectively solved in the production of cheese yarn.
氢氧化钾
  氢氧化钾是白色粉末或片状固体,具强碱性及腐蚀性,溶于水、乙醇,微溶于乙醚,极易吸收空气中水分而潮解,吸收二氧化碳而成碳酸钾,当溶解于水、醇或用酸处理时产生大量热量。但是大家对它的易潮解性有多少了解呢?下面就给大家来具体讲解一下吧。
  Potassium hydroxide is a white powder or flaky solid with strong alkalinity and corrosiveness. It is soluble in water and ethanol and slightly soluble in ether. It is easy to absorb moisture in air and deliquescence. It absorbs carbon dioxide to form potassium carbonate. When it is dissolved in water, alcohol or treated with acid, it produces a lot of heat. But how much do you know about its deliquescence? Now let's give you a detailed explanation.
  易潮解:氢氧化钾暴露于空气中时,易吸收二氧化碳和水分,逐渐变成碳酸钾。易溶于水,溶解时放出大量溶解热,有极强的吸水性,在空气中能吸收水分而溶解,并吸收二氧化碳逐渐变成碳酸钾。溶于乙醇,微溶于醚。有极强的碱性和腐蚀性,其性质与烧碱相似。能引起灼伤,易于吸收空气中的水分和CO2。
  Easy deliquescence: Potassium hydroxide is easy to absorb carbon dioxide and water when exposed to air, and gradually becomes potassium carbonate. It is easy to dissolve in water and releases a lot of heat of dissolution when dissolving. It has strong water absorption. It can absorb water and dissolve in air, and absorb carbon dioxide and gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has strong alkalinity and corrosiveness, and its properties are similar to those of caustic soda. Can cause burns, easy to absorb moisture and CO2 in the air.
  以上就是给大家总结的关于氢氧化钾易潮解性的简单介绍,希望大家都有一定的学习,另外,在大家使用的时候一定注意,避免给自身带来伤害,想了解更多资讯,请继续关注我们吧。
  Above is a brief introduction about the deliquescence of potassium hydroxide summarized for you. I hope you all have some learning. In addition, when you use potassium hydroxide, you must pay attention to avoid harming yourself. If you want to know more information, please continue to pay attention to us.
