氫氧化鉀屬于強酸，在應用的情況下，我們會發現一些產品的顏色變黑，這是因為產品在生產中的情況，在這個過程中有一些錯誤，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. In the case of application, we will find that the color of some products turns black, which is due to the production of the products. There are some errors in this process. Let's have a detailed understanding of the reasons why the color of potassium hydroxide turns black.

當機械設備處于微正壓狀態時，能合理防止氣體進入系統軟件。因此，在制造過程中，氮氣密封的機械設備都是在加料后使用，進入氮氣的設備總是處于高溫強酸狀態。當二氧化碳進入時，會加劇鎳材料的侵蝕，從而增加其中的鎳含量，進而使色調變黑。

When the mechanical equipment is in the micro positive pressure state, it can reasonably prevent the gas from entering the system software. Therefore, in the manufacturing process, nitrogen sealed mechanical equipment is used after feeding, and the equipment entering nitrogen is always in a high temperature and strong acid state. When carbon dioxide enters, it will aggravate the corrosion of nickel materials, thus increasing the nickel content therein, and then darkening the tone.

當進液量較大時，液體不能正常破乳或膜太厚。在整個升溫過程中，液體往往得不到傳熱，進而達不到沸騰所需的溫度，因此不能進行揮發，這將導致整個濃縮過程不能較好地進行，甚不能進行。

When the liquid intake is large, the liquid cannot be demulsified normally or the membrane is too thick. During the whole heating process, the liquid often cannot get heat transfer, and thus cannot reach the temperature required for boiling, so it cannot volatilize, which will lead to the whole concentration process can not be carried out well, or even can not be carried out.

盡量規避頻繁駕駛和停放機械設備。因為每次開車時，燒堿溶液都會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行清洗和蝕刻，所以在整個開車過程中，黑堿是不可規避的。

Try to avoid frequent driving and parking of mechanical equipment. Because caustic soda solution will wash away a layer of nickel oxide that can maintain the surface of nickel material each time when driving, and then clean and etch the next layer of nickel material, black alkali is unavoidable during the whole driving process.

開車前，用蒸汽吹掃系統軟件，保障有較足的工作壓力和吹掃時間。

Before start-up, use steam purging system software to ensure sufficient working pressure and purging time.
