Potassium hydroxide needs color matching in the production process, so the products after color matching will generally appear white, which is also because some impurities may affect its color during the processing process. So today, let's take a look at how to color the alkaline materials.

1、處理調色的操作人員需要在在上崗之前穿戴好防護裝備。

1. The operators who deal with color matching first need to wear protective equipment before taking up their posts.

2、等到調色鍋當中的液堿沉淀差不多2個小時之后可以開始進行調色處理。

2. When the liquid alkali precipitates in the toner for about 2 hours, the color mixing can be started.

3、在沉淀的時候操作人員是需要適當的對煤氣閥門進行調整，來確保液堿溫度持續的在450- 500 度范圍之內。

3. In the process of precipitation, the operator needs to adjust the gas valve properly to ensure that the liquid alkali temperature is continuously within the range of 450-500 degrees.

4、是需要添加進去硝酸鈉把當中的雜質都沉淀出來，然后再添加進去硫磺粉來對氫氧化鉀的顏色進行調節而且還可以加速雜質的沉淀。

4. First of all, we need to add sodium nitrate to precipitate the impurities, and then add sulfur powder to adjust the color of potassium hydroxide, and also can accelerate the precipitation of impurities.

5、需要取少量的液堿放入到取樣盤當中，然后觀察顏色已經呈現乳白色之后即可送入到檢驗室當中檢驗。

5. It is necessary to take a small amount of liquid alkali into the sampling plate, and then observe that the color is milky white, and then it can be sent to the laboratory for inspection.

6、等到化驗報告出來顯示合格之后即可把液堿打入到片堿機當中來進行出堿作業。

6. After the test report shows that it is qualified, the liquid caustic soda can be injected into the flake caustic soda machine to carry out alkali production.

7、需要調整一下沾料斗的高度從而保持滾筒和液堿處于一個接觸的狀態。

7. It is necessary to adjust the height of the dip hopper to keep the drum in contact with the liquid caustic soda.

8、需要開啟一下循環水真空泵然后觀察循環水的流量是否滿足出堿的水平。等到已經是滿足了出堿的水平之后即可通知包裝的工作人員來對其進行調整。

8. It is necessary to turn on the circulating water vacuum pump, and then observe whether the circulating water flow meets the alkali discharge level. When the alkali level has been met, the packaging staff can be informed to adjust it.

9、需要打開立式堿泵然后輸送液堿到相應的設備中。并且在輸送的時候需要注意觀察著出堿速度要適中。

9. It is necessary to open the vertical alkali pump and then transport the liquid alkali to the corresponding equipment. In addition, it is necessary to pay attention to observe that the speed of alkali production should be moderate.

10、等到調色鍋當中的液堿清空之后即可關閉停止工作。

10. When the liquid alkali in the toner is empty, it can be shut down and stop working.

氫氧化鉀進行的調色工作是非常重要的，并且在經過調色工作之后是需要進行檢查的，經過檢查合格之后的產品才可以繼續的來進行使用。

The color matching work of potassium hydroxide is very important, and it needs to be checked after the color matching work, and the products that pass the inspection can be used continuously.
