氫氧化鉀屬于強酸，可較廣的應用于電鍍工藝或作為化工原料應用，但在應用的情況下，我們會(huì )發(fā)現一些產(chǎn)品的顏色變黑，這是因為產(chǎn)品在生產(chǎn)中的情況，在這個(gè)過(guò)程中有一些錯誤，讓我們詳細了解一下氫氧化鉀色調變黑的原因。
Potassium hydroxide is a strong acid, which can be widely used in electroplating process or as chemical raw materials. However, in the case of application, we will find that the color of some products turns black, because there are some errors in the production process. Let's learn more about the reason why the color of potassium hydroxide turns black.
1.氮氣密封機械和設備應在驅動(dòng)和進(jìn)給后使用
1. Nitrogen sealing machinery and equipment shall be used after driving and feeding
當機械設備處于微正壓狀態(tài)時(shí)，能合理防止氣體進(jìn)入系統軟件。因此，在制造過(guò)程中，氮氣密封的機械設備都是在加料后使用，進(jìn)入氮氣的設備總是處于高溫強酸狀態(tài)。當二氧化碳進(jìn)入時(shí)，會(huì )加劇鎳材料的侵蝕，從而增加其中的鎳含量，進(jìn)而使色調變黑。

When the mechanical equipment is in micro positive pressure state, it can reasonably prevent gas from entering the system software. Therefore, in the manufacturing process, the mechanical equipment sealed with nitrogen is used after feeding, and the equipment entering nitrogen is always in the state of high temperature and strong acid. When carbon dioxide enters, it will aggravate the corrosion of nickel materials, increase the nickel content, and then darken the tone.
2.工作能力操縱
2. Operation ability
當進(jìn)液量較大時(shí)，液體不能正常破乳或膜太厚。在整個(gè)升溫過(guò)程中，液體往往得不到傳熱，進(jìn)而達不到沸騰所需的溫度，因此不能進(jìn)行揮發(fā)，這將導致整個(gè)濃縮過(guò)程不能較好地進(jìn)行，甚至不能進(jìn)行。
When the liquid inflow is large, the liquid cannot demulsify normally or the film is too thick. In the whole heating process, the liquid often can not get heat transfer, and then can not reach the temperature required for boiling, so it can not volatilize, which will lead to the whole concentration process can not be carried out well, or even can not be carried out.
3.減少開(kāi)車(chē)和停車(chē)的頻率
3. Reduce the frequency of parking and driving
盡量規避頻繁駕駛和停放機械設備。因為每次開(kāi)車(chē)時(shí)，燒堿溶液都會(huì )沖走一層對鎳材料表面有保養作用的氧化鎳層，然后再對下一層鎳材料進(jìn)行清洗和蝕刻，所以在整個(gè)開(kāi)車(chē)過(guò)程中，黑堿是不可規避的。
Try to avoid frequent driving and parking of mechanical equipment. During each start-up, caustic soda solution will wash away a nickel oxide layer that can maintain the surface of nickel materials, and then clean and etch the next layer of nickel materials. Therefore, black alkali can not be avoided during the whole start-up process.
4.開(kāi)車(chē)前給機器蒸一下蒸汽
4. Steam the machine before driving
開(kāi)車(chē)前，用蒸汽吹掃系統軟件，保障有較足的工作壓力和吹掃時(shí)間。
Before start-up, steam purging system software shall be used to ensure sufficient working pressure and purging time.
