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.

　　另外氫氧化鉀的堿性相比于純堿、燒堿等要弱很多，可以將它撒在需要防潮的物品上面，既起到了防潮的作用又對物品的質(zhì)量造成不了影響。但是在一些大型的常年有水的地方不建議使用它，如果水和它的比例不成正比的話不僅不會起到相關(guān)的作用，還會影響周圍的環(huán)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.
