In the chemical industry, there are many precautions for different products in the storage mode, because they have different characteristics and storage environment requirements, so you should be very careful when selecting storage containers. Potassium hydroxide is a highly alkaline chemical whose solution is usually in a glass bottle, but corks do not need to be made of glass. So, what's the reason why it can't be used with frosted glass plug? The analysis is as follows.

玻璃瓶和磨砂玻璃塞的成分是一樣的，KOH是強(qiáng)堿，玻璃的成分有SiO2, SiO2和KOH反應(yīng)會(huì)生成K2SiO3。但是反應(yīng)很緩慢。玻璃瓶的內(nèi)部很光滑，反應(yīng)很緩慢，基本反應(yīng)不會(huì)是怎樣的，而且由于磨砂瓶口的粗糙，會(huì)使氫氧化鉀溶液與玻璃接觸面積增大，使反應(yīng)加快。生成K2SiO3后，瓶子會(huì)粘在嘴上，無法打開。所以要用橡皮塞換，另外:即使是磨砂口，反應(yīng)也很慢，也要1、2個(gè)月不開才能貼。但是沒有人總是用氫氧化鉀溶液，所以附著的概率比較大，所以我們只好用橡皮塞。

The composition of glass bottle and ground glass plug is the same. KOH is a strong alkali. The composition of glass is SiO2. The reaction of SiO2 and KOH will produce k2SiO3. But the response was slow. The inner part of the glass bottle is very smooth and the reaction is very slow. The basic reaction will not be how it is. Moreover, due to the rough mouth of the frosted bottle, the contact area between the potassium hydroxide solution and the glass will be increased and the reaction will be accelerated. After k2SiO3 is generated, the bottle will stick to the mouth and cannot be opened. So we need to replace it with a rubber stopper. In addition, even if it is a frosted mouth, the reaction is very slow, and it can only be pasted after 1 or 2 months. But no one always uses potassium hydroxide solution, so the probability of adhesion is relatively high, so we have to use rubber stoppers.

以上就是氫氧化鉀不能和磨砂玻璃塞一起使用的原因，也是為什么磨砂玻璃塞需要用橡膠代替的原因。我希望你能對(duì)它有一些了解，以便將來為它選擇合適的瓶塞。強(qiáng)堿不僅對(duì)儲(chǔ)存容器和瓶塞的小細(xì)節(jié)敏感，而且對(duì)許多我們需要了解的其他東西也很敏感。

That's why potassium hydroxide can't be used with ground glass plugs, and why ground glass plugs need to be replaced by rubber. I hope you know something about it so that you can choose the right cork for it in the future. Strong bases are sensitive not only to small details of storage containers and stoppers, but also to many other things we need to know.
