The storage and transportation of lime should pay attention to fire and explosion prevention because when lime meets water, it will release a lot of heat, resulting in volume expansion, which is easy to cause fire. If it needs to be stored for a long time, it is better to process the lime into lime slurry and store it in a closed container to prevent carbonization.
The storage period of lime should not exceed one month. It should be stored in a dry environment with good moisture-proof measures. Lime (including lime block and lime powder) has strong moisture absorption. Therefore, in the storage process, we must pay attention to the following points: Besides, if the quick lime or hydrated lime is exposed to the atmosphere for a long time and constantly absorbs carbon dioxide, it will transfer into calcium carbonate powder which has no gelling ability. When artificial hydrating, water can not fully penetrate the lime block so that affecting the use. If it is not stored properly, quick lime will first react with moisture in the air and form CaHO2 on the surface, meanwhile react with CO2 to form CaCO3 and create a hard skin. Quick lime has a higher requirement for storage conditions, while moisture in the air coexists with CO2. What lime fears most during storage is water, followed by CO2.

Therefore, how to store lime safely and properly has become a question that many people concerned about.īefore storing lime, we should understand the unique properties of lime, and then create a safe storage environment. Many enterprises use a massive amount of lime in the production process. As we know, lime plays an important role in civil engineering, medicine field, food production, and agricultural production because of its wide distribution of raw materials, simple production process, and low cost. Hydrated lime is obtained by the hydration of massive quick lime with a proper amount of water. For the convenience of use, block quick lime is often processed into quick lime powder, hydrated lime powder, or lime paste. Quick lime is a kind of white or gray block. According to its chemical composition, it can be divided into quick lime and hydrated lime. It is mainly composed of calcium oxide and magnesium oxide and has strong alkalinity.
