氫氧化鉀的性質(zhì)活泛，用途也廣泛，當(dāng)它應(yīng)用于醫(yī)藥、日用化工等多個(gè)領(lǐng)域中時(shí)，也可能有需要進(jìn)行調(diào)色的時(shí)候，那么，它在進(jìn)行調(diào)色時(shí)需要注意哪些事項(xiàng)呢？下面我們就來(lái)講解一下

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、上崗前穿戴好勞保防護(hù)用品。

1. Wear PPE before work.

2、調(diào)色鍋液堿沉淀2小時(shí)后開(kāi)始調(diào)色作業(yè)。

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

3、沉淀過(guò)程時(shí)調(diào)色工要調(diào)節(jié)煤氣閥門以保持液堿溫度在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、先行加入硝酸鈉進(jìn)行雜質(zhì)的沉淀后在加入硫磺粉調(diào)節(jié)液堿的顏色以加速雜質(zhì)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、取出少量液堿到取樣盤觀察顏色呈乳白色是方可送化驗(yàn)室化驗(yàn)。

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、帶化驗(yàn)報(bào)告出來(lái)后方可將液堿打入氫氧化鉀機(jī)進(jìn)行出堿作業(yè)。

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

7、調(diào)節(jié)機(jī)器沾料斗得高度，以保持滾筒與液堿保持接觸。

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

8、打開(kāi)循環(huán)水真空泵，觀察循環(huán)水的流量是否達(dá)到出堿水平。通知包裝工進(jìn)行作業(yè)。打開(kāi)電源開(kāi)關(guān)，打開(kāi)龍絞機(jī)電源開(kāi)關(guān)。

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、打開(kāi)立式堿泵輸送液堿到設(shè)備里。注意觀察出堿速度。

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

10、待調(diào)色鍋內(nèi)液堿清空后，方可關(guān)閉。絞龍機(jī)的電源開(kāi)關(guān)。

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險(xiǎn)性，無(wú)論是否清楚其危險(xiǎn)性，我們都要小心謹(jǐn)慎地使用和儲(chǔ)存它氫氧化鉀要遠(yuǎn)離易燃、可燃物。避免產(chǎn)生粉塵，避免與酸類接觸。如果您還有什么問(wèn)題，都可以和我們http://www.jonakata.com咨詢，針對(duì)您的問(wèn)題，我們會(huì)為您做出講解。

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.
