氢氧化钾在化妆品领域应用较广，使用时对其质量要求较高。如果里面有很多其他成分，使用时可能达不到预期效果。即使用在化妆品中，对皮肤也是有害的，那么使用时应该如何决定杂质的含量呢。

Potassium hydroxide is widely used in cosmetics, and its quality requirements are high. If there are many other ingredients inside, the expected effect may not be achieved when used. Even when used in cosmetics, it is harmful to the skin, so how should the content of impurities be determined when using it.

1.先用天平称出准确的样品重量1.5-2.0g，然后置于250ml烧杯中，加入蒸馏水溶解。溶解完成后，可将其放入相同尺寸的容量瓶中，待水溶解250ml后停止加水。

1. First, use a balance to weigh the accurate sample weight of 1.5-2.0g, then place it in a 250ml beaker and add distilled water to dissolve. After dissolution, put it into a volumetric flask of the same size, and stop adding water when the water is dissolved to 250ml.

2.将溶解液均匀倒入三个锥形瓶中，加入两滴酚酞指示剂。然后逐滴加入盐酸溶液，直溶液由红色变为无色。然后记录所用盐酸的体积，并添加2滴甲基橙指示剂。同样，用盐酸标准溶液滴定，直到溶液变成橙色。

2. Evenly pour the solution into three conical flasks and add two drops of phenolphthalein indicator. Then add hydrochloric acid solution dropwise until the solution changes from red to colorless. Then record the volume of hydrochloric acid used and add 2 drops of Methyl orange indicator. Similarly, titrate with hydrochloric acid Standard solution until the solution turns orange.

3.然后记录两次加入盐酸溶液的体积，据此计算产品的杂质含量。

3. Then record the volume of hydrochloric acid solution added twice and calculate the impurity content of the product based on this.

现在氢氧化钾的厂家很多，所以他们之间的竞争也很激烈，所以除了在上做让步，我们还需要把产品质量做得较好，因为市场上的产品质量参差不齐，所以如果我们的产品质量很高，那么消费者比较愿意购买质量较好的产品现在就让我们一起来学习如何增加产品的质量。

At present, there are many potassium hydroxide manufacturers, so the competition between them is also very fierce. In addition to making concessions on price, we also need to improve the product quality. Because the product quality in the market is uneven, so if our product quality is very high, then consumers are more willing to buy products with better quality. Now let's learn how to increase the product quality together.

1.当浓缩成片状烧碱时，加热过程中一般以熔盐为介质，熔盐需要用氢气燃烧炉获得热源。燃烧炉放热时，需要处于稳定状态，以保持熔盐温度和流量相对平衡。它只有在相对稳定的状态下才能被加热。一般情况下，选厂后碱温需达到380-400℃。

When concentrated into flakes of caustic soda, the heating process usually uses molten salt as the medium, and the molten salt needs to be burned in a hydrogen furnace to obtain a heat source. When the combustion furnace releases heat, it needs to be in a stable state to maintain a relative balance between the molten salt temperature and flow rate. It can only be heated in a relatively stable state. In general, the alkali temperature after plant selection needs to reach 380-400 ℃.

2.加热时，要控制好高压蒸汽的压力和温度。一般情况下，温度在190-210℃之间比较适合。

2. When heating, it is necessary to control the pressure and temperature of high-pressure steam. In general, a temperature range of 190-210 ℃ is more suitable.

3.在加热过程中，需要保持设备处于密封状态。在高压加热过程中，要避开与空气接触。

During the heating process, it is necessary to keep the equipment in a sealed state. During high-pressure heating, avoid contact with air.

介绍了增加氢氧化钾质量的关键。在加热过程中，应控制加热过程中的压力和温度，包括加热过程中不漏气。还有相关的产品信息就来我们网站http://www.jinhao360.com咨询吧！
