First, let's take a brief look at quicklime. In terms of chemical composition, lime is mainly composed of calcium oxide, chemical formula is CaO, it has a strong alkali corrosion. At present, the usual method for obtaining quick lime is still high temperature calcination. It is the use of industrial means to calcinate natural rocks, which are mainly composed of calcium carbonate, at high temperatures, which causes them to decompose into carbon dioxide gas and calcium oxide, that is, quick lime. There are many natural rocks in nature that can be used to obtain quicklime, such as dolomitic limestone, limestone, and chalk.

In the past, we can use the method of spreading quicklime to disinfect and dry the house when the initial disinfection of damp and dark rooms that have not been inhabited for a long time, which mainly uses its alkali corrosion. However, for modern home life, this method has long been eliminated, and we prefer clean and easy-to-care comprehensive preparations for indoor use.

In modern times, quicklime is widely used in industry and construction. Because of its good dryness, it was often used to make desiccant in the early days, but due to various accidents caused by ingestion or random discarding in recent years, quicklime desiccant has slowly withdrawn from the market. In terms of drying properties, quicklime is also used in the dehydration process of steel, leather, medicine and other industries.

Through the above introduction, we can see that the alkali of lime is very strong, and it also has a corrosion that can not be ignored, which is the main reason why it is slowly withdrawing from our daily life. At present, the main use of lime is in construction, but because of its strong alkali and corrosiveness, we must be careful once we "encounter" it in life, so as not to cause irreparable harm to ourselves.
