The main component of slaked lime is calcium hydroxide (Ca(OH)2).
Slaked lime, with calcium hydroxide (Ca(OH)2) as its main component, is a white powder. It is moderately alkaline. When in contact with water it can release a certain amount of heat.
In construction, it is used in making mortar and plaster. It helps bind materials together and provides a smooth finish.In agriculture, it can be used to improve acidic soils. By adjusting the soil pH, it makes the soil more suitable for plant growth.In the environmental field, slaked lime can be applied in wastewater treatment. It can help remove heavy metals and neutralize acidic substances in the water.
What are the applications of Slaked lime?
1.In the construction industry:
· It is used to prepare building materials such as lime mortar and lime plaster. These are used for bricklaying and
wall plastering, providing adhesion and filling.
· When mixed with sand and other materials, it forms a composite soil called "three-mix soil" which is used for
foundation treatment and ground paving, enhancing the stability and durability of the ground.
- As a soil amendment, slaked lime is an alkaline substance that can neutralize acidic soil, increase the pH value of the soil, and improve the acidity and alkalinity of the soil to make it more suitable for crop growth.
- It helps improve soil structure, increase soil permeability and water retention, promote the activity of microorganisms in the soil, and enhance soil fertility.
- It can be used to prepare pesticides like Bordeaux mixture to prevent and control crop pests and diseases.
- As a source of calcium fertilizer, it provides calcium for crops and promotes their growth and development.
- For wastewater treatment, it is used to neutralize acidic wastewater and adjust the pH value of the wastewater to meet discharge standards.
- It can react with heavy metal ions in wastewater to form insoluble hydroxide precipitates, thus removing heavy metals from wastewater.
- In industrial facilities such as coal-fired power plants, slaked lime can be used for flue gas desulfurization. It reacts with sulfur dioxide in the flue gas to form calcium sulfite and calcium sulfate, reducing sulfur dioxide emissions and lowering pollution to the atmospheric environment.
- It is used to produce other chemicals such as bleaching powder and calcium carbide.
- As a raw material, it participates in the production processes of chemicals such as soda ash and sodium hydroxide.
- Due to its hygroscopic nature, it can be used as a desiccant to absorb moisture in the air and keep the environment dry.
