Potassium hydroxide is very active and widely used. When it is used in medicine, daily chemical and other fields, it may be necessary to mix colors. Then, what should be paid attention to when it is mixing colors? The specific analysis is as follows.
1. Wear labor protection articles before work.
2. Start the mixing operation after the liquid alkali in the mixing pot is separated out for 2 hours.
3. In the sedimentation process, the toner should adjust the air valve to keep the temperature of liquid alkali at 450-500 ℃.
4. After adding sodium nitrate to precipitate impurities, add sulfur powder to adjust the color of liquid base and accelerate the precipitation of impurities.
5. Take out a small amount of alkali solution to the sample plate to observe whether the color is milky white, which can be sent to the laboratory for analysis.
6. Use the test report to take out the alkali solution and put it into the alkali solution operation of the potassium hydroxide machine.
7. Adjust the dip bucket height of the machine to make the drum contact with liquid alkali.
8. Open the vacuum pump of circulating water and observe whether the flow of circulating water reaches the level of alkali production. Inform the packer to do the work. Turn on the power switch, turn on the twist power switch.
9. Turn on the vertical alkali pump to transfer the liquid and alkali to the equipment. Pay attention to the basic speed.
10. It can be closed only after all the liquid alkali in the mixing pot is used up. Power switch of winch.
The above is the attention of potassium hydroxide color mixing. In this process, safety is the key, but in order to ensure the color mixing effect of the product, we need to pay more attention to control the order and quantity of various raw materials, in order to avoid failure and more losses.
