Quicklime, the main component is calcium oxide (CaO).
From the appearance, it is usually white or off-white lumpy solid. It is an alkaline oxide with the following characteristics:
In terms of chemical properties, quicklime has a strong activity. When in contact with water, a violent reaction occurs, releasing a large amount of heat and forming calcium hydroxide (hydrated lime).
It is widely used, such as in the construction field can be used to prepare mortar and treat foundation; As a soil conditioner and disinfectant in agriculture; Industrial production is chemical raw materials, metallurgical flux and so on; Environmental protection can be used for sewage treatment and waste gas treatment; Can also be used as a desiccant.
What are the applications of quicklime?
1. Construction field
1. In building construction, quicklime can be used to prepare building mortar. After it is mixed with sand and other materials, it can increase the strength and cohesiveness of the mortar and make the wall stronger.
2. Can be used for foundation treatment. By reacting with the moisture in the soil, quicklime can improve the properties of the soil and increase the bearing capacity of the foundation.
2. Agriculture
1. As a soil amendment. Quicklime can adjust the pH of soil, reduce soil acidity, improve soil structure, and is conducive to the growth of crops.
2. Used for disinfection and sterilization. It can kill bacteria, eggs and pests in the soil and reduce the occurrence of crop diseases and pests.
3. Industrial production
1. In the metallurgical industry, it can be used as a flux to help the ore melt at high temperature and improve smelting efficiency.
2. Used in the paper industry, it can accelerate cooking and improve paper quality in the pulping process.
4. Environmental protection
1. Can be used for sewage treatment. Quicklime can neutralize acidic substances in sewage, precipitate heavy metal ions, and purify sewage.
2. In the waste gas treatment, some acidic gases can be absorbed to reduce atmospheric pollution.
5. Other uses
1. Use as a desiccant. Because quicklime has a strong water absorption, it can absorb moisture in the air and prevent items from getting damp.
2. In food processing, a small amount of quick lime can be used for food drying and preservation. However, the amount must be strictly controlled when used to ensure food safety.
