Lime is an important building material widely used in the construction and chemical industries. However, lime differs in both construction and chemical applications. This article will provide a detailed introduction to the differences between lime construction and chemical applications

Lime is mainly used in the construction industry to manufacture lime mortar and lime gypsum products. Lime mortar is a commonly used material in construction, used for masonry and painting. It has good adhesion and durability, playing an important role in building structures. Lime gypsum products, including gypsum boards and gypsum decorations, are widely used in indoor decoration. These lime products are widely used in the construction industry and can provide good fire and sound insulation effects

Lime is also used in the chemical industry. In chemical processes, lime is commonly used as a reactant and neutralizer. The alkaline properties of lime make it play an important role in acid-base neutralization reactions. For example, lime can be used to neutralize wastewater and acidic soil to adjust pH values. In addition, lime is also used to produce fertilizers and industrial raw materials, such as lime kilns and limestone

Although lime plays an important role in both the construction and chemical industries, there are some differences in its use and properties. The lime used in construction is mainly non-hydrated lime, while the lime used in chemical engineering is mainly hydrated lime. Non hydrated lime is a dry powder substance that undergoes a chemical reaction after adding water, releasing heat. Hydrated lime is a powder or gel like substance that can be directly used in chemical reactions. Lime used in construction generally requires high purity to ensure the quality and performance of building materials. Chemical lime has relatively low purity requirements, mainly considering the effectiveness of chemical reactions

In addition, construction lime requires a series of processing techniques, such as the selection of limestone ore, the firing of hydrated lime, and the preparation of hydrated lime. Chemical lime generally goes through relatively simple processing processes, such as limestone mining and lime processing

In summary, the difference between lime construction and chemical use is mainly reflected in their purpose and properties. Lime used in construction is mainly used to manufacture lime mortar and lime gypsum products, while chemical lime is mainly used for chemical reactions and neutralization. In addition, the purity requirements and processing techniques of the two are also different. Understanding these differences can provide a better understanding of the application of lime in the construction and chemical industries, and provide reference for work in related fields.
