在化工行業(yè)，不同的產(chǎn)品有不同的儲(chǔ)存方式，因?yàn)樗鼈冇胁煌奶攸c(diǎn)，對(duì)儲(chǔ)存環(huán)境有不同的要求，所以?xún)?chǔ)存容器的選擇應(yīng)該非常謹(jǐn)慎。氫氧化鉀溶液是一種高堿性化學(xué)物質(zhì)，通常裝在玻璃瓶中，但軟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 cautious. Potassium hydroxide solution is a highly alkaline chemical, usually contained in glass bottles, but corks cannot be made of glass. So why can't it use frosted glass plug? The analysis is as follows.
在玻璃瓶中，KOH是一種強(qiáng)堿，就像磨碎的玻璃塞一樣。SiO2存在于玻璃中，與KOH反應(yīng)生成K2SiO3。但是反應(yīng)很緩慢。玻璃瓶的內(nèi)部非常光滑，反應(yīng)非常緩慢，所以基本上不會(huì)有太大的反應(yīng)。
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 inside of the glass bottle is very smooth and the reaction is very slow, so there will not be much reaction basically.

然而，由于磨砂瓶的口是粗糙的，氫氧化鉀溶液和玻璃之間的接觸面積會(huì)增加，使反應(yīng)更快。生成K2SiO3后，它會(huì)粘在瓶口上，無(wú)法打開(kāi)。所以改用橡膠塞吧。另外:即使是磨砂的孔也會(huì)反應(yīng)很慢，在卡住前一兩個(gè)月不會(huì)打開(kāi)。但是沒(méi)有人用舊的氫氧化鉀溶液，所以附著的概率還是比較大的，所以改用橡膠塞。
However, because the mouth of the frosting 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 switch to rubber plugs. In addition: even frosted holes will react very slowly and will not open for a month or two before they get stuck. However, no one uses the old potassium hydroxide solution, so the probability of adhesion is still relatively large, so they use rubber plugs.
以上是氫氧化鉀不能使用磨砂玻璃塞的原因，也是氫氧化鉀的瓶塞需要更換橡膠的原因。希望你能理解，以便你以后能選擇合適的瓶塞。強(qiáng)堿不僅關(guān)心儲(chǔ)存容器和軟木塞的細(xì)節(jié)，還關(guān)心很多我們需要了解的其他事情。
The above is the reason why frosted glass stopper cannot be used for potassium hydroxide, and it is also the reason why the rubber of potassium hydroxide bottle stopper needs to be replaced. I hope you can understand so that you can choose the right cork in the future. Strong alkali is not only concerned about the details of storage containers and corks, but also about many other things we need to know.
