Potassium hydroxide is widely used in our daily life and production. Today we introduce the method of making moisture-proof and dehumidifier with potassium hydroxide.

　　氢氧化钾用来制造防潮剂主要应用的是它的化学特性，通过我们实验发现如果将氢氧化钾存放在潮湿阴暗的地方，时间长了它逐渐的由干燥变成湿润了，而房屋整个的潮湿度的到了一定程度的缓解，这说明氢氧化钾有效的改善了潮湿的环境。氢氧化钾和水结合会释放出高温，但是少量的氢氧化钾和水结合会增加它的挥发性，将水挥发到空气之中，这也是我们为什么使用它制造防潮剂的主要原因。

　　Potassium hydroxide is mainly used to make moisture-proof agents because of its chemical properties. Our experiments show that if potassium hydroxide is stored in a damp and dark place, it will gradually become wet from drying over a long period of time, and the humidity of the whole house has been alleviated to a certain extent, which shows that potassium hydroxide effectively improves the humid environment. Potassium hydroxide combines with water to release high temperature, but a small amount of potassium hydroxide combines with water to increase its volatility and volatilize water into the air, which is the main reason why we use it to make moistureproof agent.

　　另外氢氧化钾的碱性相比于纯碱、烧碱等要弱很多，可以将它撒在需要防潮的物品上面，既起到了防潮的作用又对物品的质量造成不了影响。但是在一些大型的常年有水的地方不建议使用它，如果水和它的比例不成正比的话不仅不会起到相关的作用，还会影响周围的环境。

　　In addition, the alkalinity of potassium hydroxide is much weaker than that of soda, caustic soda, etc. It can be sprayed on the products that need moisture-proof, which not only plays the role of moisture-proof, but also has no effect on the quality of the products. However, it is not recommended in some large perennial areas where water is available. If the proportion of water to water is not proportional, it will not only play a related role, but also affect the surrounding environment.
