氫氧化鉀溶液是一種高堿性化學物質，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。

Potassium hydroxide solution is a highly alkaline chemical, which is usually packed in glass bottles, but corks cannot be made of glass. So, why can't it use frosted glass plugs? The analysis is as follows.

1、很多玻璃器皿所使用的玻璃量往往比較大，這也是因為這類玻璃對工藝要求比較高，所以一般需要添加適當的劑量才能使效果更好。

1. The amount of glass used in many glassware is often large, which is also because this kind of glass has high technological requirements, so it is generally necessary to add an appropriate dose to make the effect better.

2、很多醫療或實驗室是用玻璃瓶的頻率非常高,而且某些類型的盛放何時使用通常的化學物質,并使用氫氧化鉀玻璃使用的時間用來存儲一些其他的產品也可以。

2. Many medical or laboratory use glass bottles with a high frequency, and when certain types of containers are used with common chemicals, and when potassium hydroxide glass is used to store some other products can also be used.

3、現在很多家庭在使用玻璃的時候都是很多會在上面刻一些花紋和其他花紋的，所以在加工的時候需要在適當的量上添加用量。

3. Nowadays, many families will carve some patterns and other patterns on the glass when they use it, so it is necessary to add the appropriate amount when processing.

4、很多光學玻璃，比如鏡面和透視鏡在使用時的效果都比較好。

4. Many optical glasses, such as mirrors and perspective glasses, have good effects when used.

在玻璃瓶中，KOH是一種強堿，就像磨碎的玻璃塞一樣。SiO2存在于玻璃中，與KOH反應生成K2SiO3。但是反應很緩慢。玻璃瓶的內部非常光滑，反應非常緩慢，所以基本上不會有太大的反應。

In glass bottles, KOH is a strong alkali, just like a ground glass stopper. SiO2 exists in glass and reacts with KOH to form K2SiO3. But the reaction was slow. The inside of the glass bottle is very smooth, and the reaction is very slow, so there will be little reaction.

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增加，使反應更快。生成K2SiO3后，它會粘在瓶口上，無法打開。所以改用橡膠塞吧。

However, because the mouth of the frosted 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.

另外:即使是磨砂的孔也會反應很慢，在卡住前一兩個月不會打開。但是沒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。

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 high, so the rubber stopper is used instead.

以上是氫氧化鉀不能使用磨砂玻璃塞的原因，也是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。更多相關內容就來我們網站http://www.shrisa.cn咨詢了解吧！

These are the reasons why the ground glass stopper cannot be used for potassium hydroxide, and why the rubber of the bottle stopper needs to be replaced.
