The difference between lime construction and chemical industry

Application of 1. lime in construction

in the construction industry, lime is mainly used to make mortar (binder) and plaster (putty). Its main feature is its alkaline nature, which can react with water to form calcium hydroxide, thereby enhancing the adhesion and durability of the material. Lime for construction is usually composed of CaO, with clay and other minerals, and is calcined.

Common uses of lime for construction include:

1. masonry Materials: Used for the production of wall tiles, floor tiles, etc.
2. putty: Used for the basic treatment of the wall surface to improve the adhesion of the brush.
3. Concrete admixture: As water-watering agent or water-reducing agent, improve the workability of concrete.

The use scenario of lime for construction is usually in the construction of interior and exterior walls, especially in building environments where high strength and durability are required.

Application of 2. Lime in Chemical Industry

in the chemical industry, the main use of lime is as a reducing agent and dehydrating agent. Its chemical properties determine its important position in chemical production.

1. chemical raw materials lime is an important raw material for the production of other chemical products, such as quicklime(CaO), quicklime(CaO · H2O), etc.
2. Reducing agent in the redox reaction, lime, as a strong alkaline reducing agent, can neutralize acidic substances and promote the reaction.
3. dehydrating agent in organic chemistry, lime is used in dehydration reactions to help produce stable carbohydrates.

The use of lime for chemical industry mainly focuses on the supply of raw materials and process optimization in the chemical production process.

Application of Lime in Inorganic Chemical Industry

as an important raw material of inorganic chemical industry, lime is widely used in:

• cement industry: Production of quicklime and quicklime.
• Glass Manufacturing: Used in the preheating and melting process of raw materials.
• phosphate fertilizer production: As an important raw material for production.

In chemical production, the use of lime is usually large, so its quality and purity have an important impact on its production efficiency and product quality.

The difference between 3. lime for construction and chemical industry

1. differences in form and use:

• building lime is mostly block or powder, used for material production.
• Chemical lime is mostly powder, as raw materials used directly.

1. Different chemical properties:

• lime for construction is mainly used for alkaline reaction.
• Chemical lime is mainly used for neutral and strong alkaline reactions, such as dehydration, neutralization and so on.

1. Application areas:

• building lime is mainly used for building structures and decorative materials.
• Chemical lime is used for raw material supply and process optimization in chemical production processes.

1. mode of production:

• lime for construction is usually made by calcining raw materials such as clay.
• Lime for chemical industry is usually produced by industrial calcination of high purity raw materials.

4. Conclusion

as a chemical material and building material, there are significant differences in the use and application of lime. Building lime is mainly used for the production of structural and decorative materials, while chemical lime is used as an important raw material to participate in various chemical reactions. Understanding the difference between lime in construction and chemical industry is of great significance for rational utilization of resources and improvement of production efficiency. In the future, with the continuous progress of the chemical industry, the application of lime in the field of construction and chemical industry will be more extensive and in-depth.
