在化工行业，不同的产品有不同的储存方式，因为它们有不同的特点，对储存环境有不同的要求，所以储存容器的选择应该非常谨慎。氢氧化钾溶液是一种高碱性化学物质，通常装在玻璃瓶中，但软木塞不能用玻璃制成。那么，它不能使用磨砂玻璃塞的原因是什么呢?分析如下。
　　In the chemical industry, different products have different storage methods, because they have different characteristics and different requirements for storage environment, so the selection of storage containers should be very careful. Potassium hydroxide solution is a highly alkaline chemical, usually in glass bottles, but corks cannot be made of glass. So, what's the reason why it can't use frosted glass plug? The analysis is as follows.
　　在玻璃瓶中，KOH是一种强碱，就像磨碎的玻璃塞一样。SiO2存在于玻璃中，与KOH反应生成K2SiO3。但是反应很缓慢。玻璃瓶的内部非常光滑，反应非常缓慢，所以基本上不会有太大的反应。然而，由于磨砂瓶的口是粗糙的，氢氧化钾溶液和玻璃之间的接触面积会增加，使反应更快。生成K2SiO3后，它会粘在瓶口上，无法打开。所以改用橡胶塞吧。另外:即使是磨砂的孔也会反应很慢，在卡住前一两个月不会打开。但是没有人用旧的氢氧化钾溶液，所以附着的概率还是比较大的，所以改用橡胶塞。

　　In a glass bottle, Koh is a strong alkali, just like a ground glass stopper. SiO2 exists in glass and reacts with KOH to form k2SiO3. But the response was slow. The inner part of the glass bottle is very smooth and the reaction is very slow, so basically there will not be too much reaction. However, because the mouth of the grinding bottle is rough, the contact area between the potassium hydroxide solution and the glass will increase, making the reaction faster. After k2SiO3 is generated, it will stick to the bottle mouth and cannot be opened. So use rubber plugs instead. In addition: even frosted holes will react very slowly and will not open for a month or two before being stuck. But no one uses the old potassium hydroxide solution, so the probability of adhesion is relatively large, so we use rubber plug instead.
　　以上是氢氧化钾不能使用磨砂玻璃塞的原因，也是氢氧化钾的瓶塞需要更换橡胶的原因。希望你能理解，以便你以后能选择合适的瓶塞。强碱不仅关心储存容器和软木塞的细节，还关心很多我们需要了解的其他事情。
　　The above is the reason why potassium hydroxide can not use ground glass stopper, and also the reason why the stopper of potassium hydroxide needs to be replaced with rubber. I hope you can understand, so that you can choose the right cork in the future. Strong base is not only concerned about the details of storage containers and corks, but also about many other things we need to know.
