氢氧化钾属于强酸，在应用的情况下，我们会发现一些产品的颜色变黑，这是因为产品在生产中的情况，在这个过程中有一些错误，让我们详细了解一下氢氧化钾色调变黑的原因。

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.

当机械设备处于微正压状态时，能合理防止气体进入系统软件。因此，在制造过程中，氮气密封的机械设备都是在加料后使用，进入氮气的设备总是处于高温强酸状态。当二氧化碳进入时，会加剧镍材料的侵蚀，从而增加其中的镍含量，进而使色调变黑。

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.

当进液量较大时，液体不能正常破乳或膜太厚。在整个升温过程中，液体往往得不到传热，进而达不到沸腾所需的温度，因此不能进行挥发，这将导致整个浓缩过程不能较好地进行，甚不能进行。

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.

尽量规避频繁驾驶和停放机械设备。因为每次开车时，烧碱溶液都会冲走一层对镍材料表面有保养作用的氧化镍层，然后再对下一层镍材料进行清洗和蚀刻，所以在整个开车过程中，黑碱是不可规避的。

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.

开车前，用蒸汽吹扫系统软件，保障有较足的工作压力和吹扫时间。

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