Product Characteristics:

Hydrated lime can also be called calcium hydroxide,Calcium hydroxide is a strong base with bactericidal and preservative properties. It has a corrosive effect on skin and fabrics. It reacts with acids to form corresponding calcium salts.

Applications:

• Flue Gas Desulfurization: Widely used for exhaust gas treatment in power plants.

• Water Treatment: Effective in water purification and sewage treatment processes.

• Industrial Use: Widely used in the construction, environmental protection, and chemical industries.

Chemical Industry

• Production of Bleaching Agents: It is a key raw material for manufacturing bleaching powder and bleaching concentrate. In the production process, calcium hydroxide reacts with chlorine to form calcium hypochlorite, which is the main component of bleaching agents and has strong bleaching and disinfecting properties.

• Production of Other Chemicals: Calcium hydroxide is used in the production of various chemicals, such as calcium carbonate, calcium phosphate, and calcium stearate. It can also be used as a catalyst or intermediate in some chemical reactions.

Paper Industry

• pH Regulation: In the paper - making process, calcium hydroxide is used to adjust the pH value of the pulp. It helps to control the acidity of the pulp, which is beneficial for improving the strength and whiteness of the paper. At the same time, it can also react with some impurities in the pulp to form precipitates, which can be removed by filtration, thereby improving the quality of the paper.

• Retention Aid: Calcium hydroxide can also be used as a retention aid in the paper industry. It can interact with the fibers and fillers in the pulp, increasing their retention rate on the paper - making net, reducing the loss of fibers and fillers, and improving the production efficiency and quality of the paper.

Rubber Industry

• Activator and Filler: In the rubber industry, calcium hydroxide is used as an activator and filler. As an activator, it can promote the vulcanization reaction of rubber, improve the cross - linking density of rubber, and enhance the mechanical properties of rubber products. As a filler, it can increase the volume of rubber products, reduce production costs, and at the same time improve the hardness and wear resistance of rubber products.

Calcium hydroxide is also widely used in flue gas desulfurization.

Application Methods

• Wet desulfurization: Calcium hydroxide is made into lime milk, which is a suspension of calcium hydroxide. Then, the lime milk and flue gas are brought into full contact through spraying and other methods. In the absorption tower, sulfur dioxide in the flue gas reacts with calcium hydroxide in the lime milk to form calcium sulfite and calcium sulfate. This method has a high desulfurization efficiency, which can reach over 90%, effectively removing sulfur dioxide from the flue gas.

• Semi - dry desulfurization: Calcium hydroxide powder is mixed with water to form calcium hydroxide particles with a certain humidity, and then they are sprayed into the flue gas. During the reaction process, on one hand, the calcium hydroxide particles react chemically with sulfur dioxide; on the other hand, the water evaporates, and the reaction products are discharged in a dry state. Semi - dry desulfurization has the advantages of a simple system and low investment cost. Meanwhile, the desulfurization efficiency can also reach 70% - 90%.

• Dry desulfurization:

  Calcium hydroxide powder is directly sprayed into the flue gas, and it reacts with sulfur dioxide at high temperatures. The advantage of dry desulfurization is its simple process and no wastewater discharge. However, the desulfurization efficiency is relatively low, generally around 60% - 80%.

Our Advantages

We have our own mine in Hubei Province, which endows us with the following advantages:

• Stable Raw Material Supply: Owning our own mine ensures a stable supply of raw materials for calcified substances. This helps to avoid production interruptions caused by issues such as fluctuations in the raw material market and supply shortages. It guarantees the smooth progress of production plans and maintains a stable product output, enabling us to better meet customer needs and enhance customer satisfaction.

• Controllable Raw Material Quality: Our company can directly manage and monitor the mining process of the mine, and strictly control the quality of raw materials. We are able to select appropriate ore grades and qualities according to production requirements, ensuring that the mined ore meets the high standards of our products. This provides a solid foundation for producing high-quality calcified substance products and helps to enhance the market competitiveness of our products.

• Cost Advantage: Obtaining raw materials from our own mine reduces intermediate procurement links and lowers procurement costs. Moreover, in the long run, a stable raw material supply also enables our company to take the initiative in cost control and avoid the risk of cost increases due to fluctuations in raw material prices, thereby improving the company's economic benefits and profitability.
