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

隔膜電解法的原料氯化鉀在化鹽槽溶化成飽和溶液。加熱90℃時分別加入碳酸鉀。苛性鉀。氯化鋇除去鈣。鎂和硫酸根等雜質。經沉降除渣。鹽酸中和。280～315g/L的氯化鉀溶液經預熱到70～75℃后進行電解。得氫氧化鉀。

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.

隔膜法所得的產品濃度為百分之十到百分之十一，需通過蒸發濃縮和冷卻澄清。制得含百分之四十五到五十產品溶液；也可繼續在熬堿鍋中濃縮。經脫色。制得固體的產品。或經制片成片狀產品。

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.

以上就是給大家總結的關于氫氧化鉀的隔膜電解法的相關內容，大家在以后的操作使用中，要多注意這方面的知識，多了解產品的制成方法，方便自己分辨產品的應用領域，對大家的產品使用都是有幫助的。

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.
