氢氧化钾在制作的过程当中是需要进行调色的，如此经过调色之后的产品一般是会呈现白色的，这也是因为在处理的过程当中可能会有一些杂质等影响到其本身的颜色，那么今天我们看看碱性物质是如何进行调色的吧。
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、首先处理调色的操作人员需要在在上岗之前穿戴好防护装备。
1. The operators who deal with color matching first need to wear protective equipment before taking up their posts.
2、等到调色锅当中的液碱沉淀差不多2个小时之后可以开始进行调色处理。
2. When the liquid alkali precipitates in the toner for about 2 hours, the color mixing can be started.
3、在沉淀的时候操作人员是需要适当的对煤气阀门进行调整，来确保液碱温度持续的在450- 500 度范围之内。
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、首先是需要添加进去硝酸钠把当中的杂质都沉淀出来，然后再添加进去硫磺粉来对氢氧化钾的颜色进行调节而且还可以加速杂质的沉淀。
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、需要取少量的液碱放入到取样盘当中，然后观察颜色已经呈现乳白色之后即可送入到检验室当中检验。
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、等到化验报告出来显示合格之后即可把液碱打入到片碱机当中来进行出碱作业。
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、需要调整一下沾料斗的高度从而保持滚筒和液碱处于一个接触的状态。
7. It is necessary to adjust the height of the dip hopper to keep the drum in contact with the liquid caustic soda.
8、需要开启一下循环水真空泵然后观察循环水的流量是否满足出碱的水平。等到已经是满足了出碱的水平之后即可通知包装的工作人员来对其进行调整。
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、需要打开立式碱泵然后输送液碱到相应的设备中。并且在输送的时候需要注意观察着出碱速度要适中。
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、等到调色锅当中的液碱清空之后即可关闭停止工作。
10. When the liquid alkali in the toner is empty, it can be shut down and stop working.
氢氧化钾进行的调色工作是非常重要的，并且在经过调色工作之后是需要进行检查的，经过检查合格之后的产品才可以继续的来进行使用。
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.
