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(xué)玻璃，比如鏡面和透視鏡在使用時(shí)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(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 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(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。

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(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。

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(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.tjxjw.com咨詢(xún)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.
