氫氧化鉀屬于強(qiáng)酸，在應(yīng)用的情況下，我們會(huì)發(fā)現(xiàn)一些產(chǎn)品的顏色變黑，這是因?yàn)楫a(chǎn)品在生產(chǎn)中的情況，在這個(gè)過程中有一些錯(cuò)誤，讓我們?cè)敿?xì)了解一下氫氧化鉀色調(diào)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(dāng)機(jī)械設(shè)備處于微正壓狀態(tài)時(shí)，能合理防止氣體進(jìn)入系統(tǒng)軟件。因此，在制造過程中，氮?dú)饷芊獾臋C(jī)械設(shè)備都是在加料后使用，進(jìn)入氮?dú)獾脑O(shè)備總是處于高溫強(qiáng)酸狀態(tài)。當(dāng)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(diào)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(dāng)進(jìn)液量較大時(shí)，液體不能正常破乳或膜太厚。在整個(gè)升溫過程中，液體往往得不到傳熱，進(jìn)而達(dá)不到沸騰所需的溫度，因此不能進(jìn)行揮發(fā)，這將導(dǎo)致整個(gè)濃縮過程不能較好地進(jìn)行，甚不能進(jìn)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(guī)避頻繁駕駛和停放機(jī)械設(shè)備。因?yàn)槊看伍_車時(shí)，燒堿溶液都會(huì)沖走一層對(duì)鎳材料表面有保養(yǎng)作用的氧化鎳層，然后再對(duì)下一層鎳材料進(jìn)行清洗和蝕刻，所以在整個(gè)開車過程中，黑堿是不可規(guī)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(tǒng)軟件，保障有較足的工作壓力和吹掃時(shí)間。

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