氢氧化钾的隔膜电解法方法是什么?

发布来源:http://www.jinhao360.com    更新时间:2021-04-15 点击数:

氢氧化钾现如今应用越来越普遍,那么大家对这种产品的知识了解有多少呢?产品的制成方法中,有一种方法叫做隔膜电解法,这种方法的制成步骤和这种方法制成的产品可以应用在哪些方面,下文为大家详解:

Potassium hydroxide is now more and more widely used, so how much do you know about this product? Among the manufacturing methods of products, there is a method called diaphragm electrolysis. The manufacturing steps of this method and the aspects in which the products made by this method can be applied are explained in detail below
隔膜电解法的原料氯化钾在化盐槽溶化成饱和溶液。加热至90℃时分别加入碳酸钾。苛性钾。氯化钡除去钙。镁和硫酸根等杂质。经沉降除渣。盐酸中和。280~315g/L的氯化钾溶液经预热到70~75℃后进行电解。得氢氧化钾。
Potassium chloride, the raw material of diaphragm electrolysis, dissolves into saturated solution in salt bath. When heated to 90 ℃, potassium carbonate was added respectively. Caustic potash. Barium chloride is used to remove calcium. Magnesium, sulfate and other impurities. The slag is removed by sedimentation. Neutralization with hydrochloric acid. 280-315g / L potassium chloride solution was preheated to 70-75 ℃ and then electrolyzed. Potassium hydroxide was obtained.
隔膜法所得的产品浓度为百分之十到百分之十一,需通过蒸发浓缩和冷却澄清。制得含百分之四十五到五十产品溶液;也可继续在熬碱锅中浓缩。经脱色。制得固体的产品。或经制片成片状产品。
The concentration of the product obtained by diaphragm method is 10% to 11%, which needs to be clarified by evaporation and cooling. A solution containing 45 to 50 percent of the product is obtained; it can also be concentrated in an alkali pot. After decolorization. A solid product. Or it can be made into pieces.
以上就是给大家总结的关于氢氧化钾的隔膜电解法的相关内容,大家在以后的操作使用中,要多注意这方面的知识,多了解产品的制成方法,方便自己分辨产品的应用领域,对大家的产品使用都是有帮助的。
The above is to summarize the relevant content of potassium hydroxide diaphragm electrolysis. In the future operation, you should pay more attention to this knowledge and know more about the manufacturing method of the product, so as to distinguish the application field of the product, which is helpful for your product use.
