氢氧化钾的性质活泛，用途也广泛，当它应用于医药、日用化工等多个领域中时，也可能有需要进行调色的时候，那么，它在进行调色时需要注意哪些事项呢？下面我们就来讲解一下

Potassium hydroxide has a wide range of properties and uses. When it is used in medicine, daily chemical industry and other fields, it may also be necessary to conduct color mixing. So what should be paid attention to when it is used for color mixing? Now let's talk about it

1、上岗前穿戴好劳保防护用品。

1. Wear PPE before work.

2、调色锅液碱沉淀2小时后开始调色作业。

2. The color mixing operation shall be started after the liquid alkali of the color mixing pot has settled for 2 hours.

3、沉淀过程时调色工要调节煤气阀门以保持液碱温度在450-500度。

3. During the sedimentation process, the color mixer shall adjust the gas valve to maintain the liquid alkali temperature at 450-500 ℃.

4、先行加入硝酸钠进行杂质的沉淀后在加入硫磺粉调节液碱的颜色以加速杂质的沉淀。

4. First add sodium nitrate to precipitate impurities, then add sulfur powder to adjust the color of liquid alkali to accelerate the precipitation of impurities.

5、取出少量液碱到取样盘观察颜色呈乳白色是方可送化验室化验。

5. Take a small amount of liquid alkali to the sampling tray and observe the color as milky white before sending it to the laboratory for testing.

6、带化验报告出来后方可将液碱打入氢氧化钾机进行出碱作业。

6. The liquid alkali can be pumped into the potassium hydroxide machine for alkali production only after the test report is brought out.

7、调节机器沾料斗得高度，以保持滚筒与液碱保持接触。

7. Adjust the height of the machine with the hopper to keep the drum in contact with the liquid alkali.

8、打开循环水真空泵，观察循环水的流量是否达到出碱水平。通知包装工进行作业。打开电源开关，打开龙绞机电源开关。

8. Open the circulating water vacuum pump and observe whether the flow of circulating water reaches the alkali level. Notify the packer to carry out the operation. Turn on the power switch and turn on the power switch of the dragon winch.

9、打开立式碱泵输送液碱到设备里。注意观察出碱速度。

9. Open the vertical alkali pump to deliver liquid alkali to the equipment. Observe the speed of alkali production.

10、待调色锅内液碱清空后，方可关闭。绞龙机的电源开关。

10. It can be closed only after the liquid alkali in the color mixing pot is emptied. The power switch of the gantry winch.

化工原料都具有一定地危险性，无论是否清楚其危险性，我们都要小心谨慎地使用和储存它氢氧化钾要远离易燃、可燃物。避免产生粉尘，避免与酸类接触。如果您还有什么问题，都可以和我们http://www.jinhao360.com咨询，针对您的问题，我们会为您做出讲解。

Chemical raw materials are dangerous to a certain extent. Whether we know the danger or not, we should use and store potassium hydroxide carefully and keep away from flammable and combustible substances. Avoid dust generation and contact with acids.
