氢氧化钾属于强酸,可较广的应用于电镀工艺或作为化工原料应用,但在应用的情况下,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, 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.氮气密封机械和设备应在驱动和进给后使用
1. Nitrogen sealing machinery and equipment shall be used after driving and feeding
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 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.工作能力操纵
2. Operation ability
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,甚至不能进行。
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.减少开车和停车的频率
3. Reduce the frequency of parking and driving
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. 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.开车前给机器蒸一下蒸汽
4. Steam the machine before driving
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, steam purging system software shall be used to ensure sufficient working pressure and purging time.
