一般人对碱的知识不足，故对于用碱来制皂这档事常心存畏惧，进而忽略使用时之安全守则，其实碱虽是一种具有高度危险的材料，但只要稍微细心一些，必可保制皂时的平安。
Most people have insufficient knowledge of alkali, so they are often afraid of using alkali to make soap, and then ignore the safety rules when using it. In fact, although alkali is a highly dangerous material, as long as it is a little careful, it can ensure the safety when making soap.
举例来说，先要知道碱很容易受潮，且容易与水结合成为「强碱」。一般来说干燥的固体状态氢氧化钠尚无很大的危险性，但它易与空气中的水结合(受潮)成为无色无味的强碱，此时就是一种具有强烈腐蚀性的物质，是具危险性的(故DIY制皂时，工作桌上不要放置饮食，以免食物沾到强碱水而误食)。
For example, we should first know that alkali is easily affected by moisture and easily combines with water to become a "strong alkali". Generally speaking, sodium hydroxide in dry solid state is not very dangerous, but it is easy to combine with water in the air (affected by moisture) to become a colorless and odorless strong alkali. At this time, it is a substance with strong corrosivity and is dangerous (so when DIY soap is made, don't put food on the work table, so as to avoid accidental eating of food stained with strong alkaline water).

因此，贮存氢氧化钾时须保证它不能与空气接触，建议用不容易破裂且可密封的罐子贮存。使用后也一定要迅速将它再度密封，免得固态的氢氧化钠与空气中的水气结合成为伤人的强碱。含水或在液体中的氢氧化钠，当水分挥发后会剩下形成白色粉状或块状的氢氧化钠，也不可对之掉以轻心，因为这些白色粉状或块状物还是属于强碱性质，接触到还是会受伤的。
Therefore, when storing potassium hydroxide, it must be ensured that it cannot be in contact with air. It is recommended to store it in a jar that is not easy to crack and can be sealed. After use, it must be sealed again quickly, so as to prevent the solid sodium hydroxide from combining with the water vapor in the air to become a harmful strong alkali. Sodium hydroxide containing water or in liquid will be left to form white powdery or blocky sodium hydroxide after the water volatilizes, and it should not be taken lightly, because these white powdery or blocky substances are still of strong alkaline nature, and they will be injured if they are exposed.
手工皂常用碱（氢氧化钠）分两种，一种是颗粒状，简称粒碱或珠碱，特点是融化快，放热剧烈，升温迅速，容易飘散，容易静电吸附；另一种是片碱，块状，融化较慢，放热稍慢，升温较慢。两种都可以，可根据自己的需要选择。
There are two kinds of alkali (sodium hydroxide) commonly used in hand soap. One is granular, which is abbreviated as granular alkali or pearl alkali. It is characterized by rapid melting, intense heat release, rapid temperature rise, easy dispersion and easy electrostatic adsorption; The other is flake alkali, massive, which melts slowly, releases heat slightly slowly, and heats up slowly. Both are OK, you can choose according to your own needs.
碱是多种元素的结合物，即不纯也不稳定，常常和其他元素或化合物产生化学反应。所以大家如果不得不去使用的时候需要提前做好相关的准备，更多事项就来网站https://www.tsswhg.com咨询吧。
Alkali is a combination of many elements, which is neither pure nor stable, and often reacts with other elements or compounds. So if you have to use it, you need to make relevant preparations in advance, and come to the website for more matters https://www.tsswhg.com Consult.
