Potassium hydroxide is widely used now. 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 the method and the aspects to which the finished products can be applied. The following is a detailed explanation from Xiaobian:

隔膜電解法的原料氯化鉀在化鹽槽中溶解成飽和溶液。當(dāng)加熱到90℃的時候，單獨加入碳酸鉀，苛性鉀，氯化鋇除鈣，鎂和硫酸鹽等雜質(zhì)。經(jīng)過沉淀然后去渣。用鹽酸中和。將280 ~ 315 g/l氯化鉀溶液預(yù)熱70 ~ 75℃,然后電解得到氫氧化鉀。

Potassium chloride, the raw material of diaphragm electrolysis, dissolves into saturated solution in the salt bath. When heated to 90 ℃, potassium carbonate, caustic potassium and barium chloride were added to remove calcium, magnesium and sulfate. After precipitation, the slag is removed. Neutralize with hydrochloric acid. Preheat 280 ~ 315 g / L potassium chloride solution to 70 ~ 75 ℃, and then electrolysis to obtain potassium hydroxide.

氫氧化鉀

Potassium hydroxide

氫氧化鉀隔膜法得到的產(chǎn)品濃度是百分之十到百分之十一，需要蒸發(fā)濃縮且冷卻澄清。配制含百分之四十五到五十的產(chǎn)品溶液；也可以在堿煮鍋中濃縮。經(jīng)過脫色制備固體產(chǎn)品或者是壓片成片狀的產(chǎn)品。

The product concentration obtained by potassium hydroxide diaphragm method is 10% to 11%, which needs evaporation concentration and cooling clarification. Prepare a 45 to 50 percent solution of the product; it can also be concentrated in an alkaline skillet. The solid product is prepared by decolorization or the product is pressed into flakes.

以上就是小編為大家總結(jié)的氫氧化鉀隔膜電解法的相關(guān)內(nèi)容。在今后的操作和使用的時候我們每個人都應(yīng)該更加重視這方面的知識，更多地的去了解產(chǎn)品的制造方法，這樣對我們區(qū)分產(chǎn)品的應(yīng)用領(lǐng)域也是有利的且還有利于每個人的產(chǎn)品使用。

The above is the summary of potassium hydroxide diaphragm electrolysis. In the future operation and use, each of us should pay more attention to this aspect of knowledge, more to understand the manufacturing method of the product, so that we can distinguish the application field of the product is also beneficial, and also beneficial to everyone's product use.
