氫氧化鉀現(xiàn)在被廣泛的進(jìn)行使用，那么你對(duì)這個(gè)產(chǎn)品又了解了多少呢？在產(chǎn)品的制造方法中，有一種叫做隔膜電解的方法。那么隔膜法氫氧化鉀濃度是多少呢？

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. What is the concentration of potassium hydroxide in the membrane process?

氫氧化鉀一般采用兩種工藝流程，一種是隔膜法(金屬陽(yáng)極)，另一種是離子膜法。雖然這兩種工藝流程的流程基本相同，但有些細(xì)節(jié)差別很大。因此，為了準(zhǔn)確地區(qū)分它們之間的差異，我們需要正確地掌握它們的過(guò)程的具體方法來(lái)確定質(zhì)量差異。

Generally, two processes are adopted for potassium hydroxide, one is diaphragm method (metal anode) and the other is ion-exchange membrane method. Although the processes of these two processes are basically the same, some details are quite different. Therefore, in order to accurately distinguish the differences between them, we need to correctly grasp the specific methods of their processes to determine the quality differences.

隔膜電解(金屬陽(yáng)極)制備氫氧化鉀的工藝流程簡(jiǎn)述如下：將滿足電解需要的精制氯化鉀水溶液連續(xù)注入金屬陽(yáng)極電解槽，用直流電電解產(chǎn)生陰極室流出物，經(jīng)蒸發(fā)器蒸發(fā)濃縮得到液體產(chǎn)品，經(jīng)連續(xù)濃縮、脫色、壓片得到固體產(chǎn)品。

The process flow of diaphragm electrolysis (metal anode) to prepare potassium hydroxide is briefly described as follows: the refined potassium chloride aqueous solution meeting the electrolysis needs is continuously injected into the metal anode electrolytic cell, and the cathode chamber effluent is generated by direct current electrolysis. The liquid product is obtained by evaporation and concentration in the evaporator, and the solid product is obtained by continuous concentration, decolorization and tablet pressing.

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(shí)候，單獨(dú)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(guò)沉淀然后去渣。用鹽酸中和。將280~315g/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 the diaphragm electrolysis method, is dissolved into a saturated solution in the salt tank. When heated to 90 ℃, add potassium carbonate, caustic potassium and barium chloride separately to remove impurities such as calcium, magnesium and sulfate. After sedimentation, the slag is removed. Neutralized with hydrochloric acid. Preheat 280 ~ 315g / L potassium chloride solution to 70 ~ 75 ℃, and then electrolyze to obtain potassium hydroxide.

隔膜法所得氫氧化鉀濃度為10%～11%，需通過(guò)蒸發(fā)濃縮和冷卻澄清，制得含45%～50%氫氧化鉀溶液;也可繼續(xù)在熬堿鍋中濃縮，經(jīng)脫色，制得固體氫氧化鉀，或經(jīng)制片成片狀氫氧化鉀產(chǎn)品。經(jīng)過(guò)脫色制備固體產(chǎn)品或者是壓片成片狀的產(chǎn)品。

The concentration of potassium hydroxide obtained by the diaphragm method is 10% ~ 11%, and the solution containing 45% ~ 50% potassium hydroxide can be prepared by evaporation concentration and cooling clarification; It can also be concentrated in the alkali boiling pot and decolorized to produce solid potassium hydroxide or flaked potassium hydroxide. Solid products are prepared by decolorization or pressed into sheets.

在今后的操作和使用的時(shí)候我們每個(gè)人都應(yīng)該多多加重視這方面的知識(shí)，更多地的去了解產(chǎn)品的制造方法，這樣對(duì)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(gè)人的產(chǎn)品使用。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.fahao168.com咨詢。

In the future operation and use, each of us should pay more attention to this knowledge and learn more about the manufacturing methods of products. This is also beneficial for us to distinguish the application fields of products and for everyone's use of products.
