在氫氧化鉀的加工中需要考慮其加工工藝和不同的處理方法，在日常使用中可能會(huì)產(chǎn)生不同的效果。所以，由于加工工藝的差異，并不是所有的產(chǎn)品都是一樣的質(zhì)量，所以差異是不可避免的，但不管是哪種工藝要正確把握具體的方法。

In the processing of potassium hydroxide, it is necessary to consider its processing technology and different treatment methods, which may produce different effects in daily use. Therefore, due to the difference in processing technology, not all products are of the same quality, so the difference is inevitable, but no matter which process is, the specific method should be correctly grasped.

(1)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。

(1) The process flow of preparing potassium hydroxide by diaphragm electrolysis (metal anode) is briefly described as follows: continuously inject the refined potassium chloride aqueous solution that meets the needs of electrolysis into the metal anode electrolytic cell, generate the cathode chamber effluent by direct current electrolysis, evaporate and concentrate the liquid product through the evaporator, and obtain the solid product through continuous concentration, decolorization and tablet pressing.

(2)離子膜電解的工藝流程

(2) Technological process of ion-exchange membrane electrolysis

以氯化鉀為原料，從離子膜電解槽流出的淡鹽水經(jīng)脫氯塔脫氯后，進(jìn)入鹽水飽和槽制成飽和鹽水。然后加入氫氧化鉀和碳酸鉀等化學(xué)物質(zhì)，使鹽水變得澄清。然而，來(lái)自澄清池的一些初級(jí)精制鹽水是懸浮固體。用于鹽水精制的螯合樹(shù)脂塔會(huì)產(chǎn)生不利影響。一般來(lái)說(shuō)，鹽水中的懸浮物小于1PP米，所以需要用鹽水過(guò)濾器過(guò)濾。

With potassium chloride as raw material, the dilute brine from the ionic membrane electrolyzer is dechlorinated by the dechlorination tower and then enters the brine saturation tank to make saturated brine. Then add chemical substances such as potassium hydroxide and potassium carbonate to make the brine clear. However, some of the primary refined brine from the clarifier is suspended solids. The chelating resin tower used for brine refining will have adverse effects. Generally speaking, the suspended solids in the brine are less than 1PP meters, so the brine filter is required.

然后經(jīng)過(guò)二次精制，即鹽水進(jìn)入螯合樹(shù)脂塔除去鈣和鎂，可加入離子膜電解槽的陽(yáng)極室；同時(shí)，純水和液堿一起進(jìn)入陰極室。直流，供電后，陽(yáng)極室產(chǎn)生的氯氣通過(guò)分離器與流出的淡鹽水分離，氯氣輸送氯氣總管。

After secondary refining, the brine enters the chelating resin tower to remove calcium and magnesium, and can be added to the anode chamber of the ionic membrane electrolyzer; At the same time, pure water and liquid caustic soda enter the cathode chamber together. After DC and power supply, the chlorine generated in the anode chamber is separated from the outgoing dilute brine through the separator, and the chlorine is delivered to the chlorine header.

淡鹽水一般含KCl200-220g/l，脫氯去飽和槽。電解槽陰極室產(chǎn)生的氫氣和30-32%的液堿也通過(guò)分離器，氫氣被輸送到氫氧總管。30-32%的液堿可以作為商品出售，或者可以送往液堿，其中48%在蒸發(fā)器中蒸發(fā)，作為商品出售，然后濃縮制成片劑和固體氫氧化鉀產(chǎn)品。

The light salt water generally contains KCl200-220g/l, which is dechlorinated to the desaturation tank. The hydrogen generated in the cathode chamber of the electrolytic cell and 30-32% of the liquid alkali also pass through the separator, and the hydrogen is delivered to the hydrogen oxygen header. 30-32% of the liquid caustic soda can be sold as a commodity or sent to the liquid caustic soda, of which 48% is evaporated in the evaporator and sold as a commodity, and then concentrated into tablets and solid potassium hydroxide products.

(3)由于加工工藝的不同，產(chǎn)品質(zhì)量也不同。與膜法相比，離子膜法加工的產(chǎn)品雜質(zhì)相對(duì)較少，質(zhì)量較高，成本價(jià)略高，售價(jià)略高。

(3) Due to different processing technologies, the product quality is also different. Compared with the membrane method, the product processed by the ionic membrane method has relatively less impurities, higher quality, slightly higher cost price and slightly higher price.

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。  我們?cè)谑褂脷溲趸洉r(shí)一定要嚴(yán)格對(duì)待，以上內(nèi)容希望能夠大幅度的幫助您，如果您想了解其他方面更多的事項(xiàng)，那就來(lái)關(guān)注我們http://m.wenping365.com吧。

Potassium hydroxide generally adopts two processes, one is diaphragm method (metal anode), and the other is ionic 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 master the specific methods of their processes to determine the quality differences. We must be strict when using potassium hydroxide. We hope that the above content can greatly help you.
