Core Advantages

High Specific Surface Area Calcium Hydroxide (referred to as High Specific Surface Area Slaked Lime) is a modified calcium-based product. Its specific surface area is far higher than that of ordinary calcium hydroxide through special technical processes, boasting four core advantages: strong reaction activity, high adsorption efficiency, low dosage and few impurities. It can be accurately adapted to scenarios with stringent requirements for reaction rate and treatment effect, reducing costs and increasing efficiency while improving product quality.

Ultra-high Specific Surface Area: The specific surface area can reach 40 ㎡/g, with a substantial increase in contact area and a more than 50% rise in reaction rate.

High Purity & Few Impurities: The purity of calcium hydroxide is ≥90%, with low content of heavy metal impurities such as iron and magnesium and no visible impurities, meeting the stringent standards of high-end industrial and environmental protection fields.

Superior Adsorption Performance: It has excellent adsorption capacity for acidic gases (e.g., SO₂, HCl), heavy metal ions and organic pollutants, with the purification efficiency 30% higher than that of ordinary products, and it is not easy to desorb after adsorption.

Stable Physical and Chemical Properties: Uniform particle size, good fluidity and non-caking property. It can maintain stable activity even in humid environments, enabling convenient storage and use.

Core Application Fields :

With excellent reaction activity and adsorption performance, the product is widely used in high-end fields such as environmental protection, chemical industry, building materials and medicine, and is especially suitable for scenarios with high requirements for treatment efficiency and product purity.

1. Environmental Protection

As a high-efficiency desulfurization and deacidification agent, it is used in flue gas desulfurization of power plants, tail gas treatment of waste incineration power generation and industrial waste gas purification, which can quickly neutralize acidic gases (SO₂, HCl, HF) with a desulfurization efficiency of over 98%. It is also applicable to sewage treatment, adsorbing heavy metal ions (Cu⊃2;⁺, Pb⊃2;⁺), fluoride ions and organic pollutants in water to realize the up-to-standard discharge of wastewater, and the sludge production is reduced by 20% compared with ordinary calcium hydroxide.

2. Chemical Industry

It is used in the synthesis of calcium carbonate, epichlorohydrin, bleaching powder and other chemical products. The high specific surface area characteristic can accelerate the reaction process, shorten the production cycle and improve the product yield. It can also be used as a catalyst carrier for catalytic reaction scenarios in fine chemical industry.

3. Building Materials

It is applied in the production of high-end waterproof coiled materials, special mortar and fireproof materials, which can improve the bonding strength, water resistance and fire retardant effect of products. It is particularly suitable for projects with stringent requirements for building material performance such as high-rise buildings, subways and tunnels.

4. Other Fields

Pharmaceutical-grade high specific surface area calcium hydroxide can be used in the production of dental materials and antacids; food-grade products can be applied to acidity adjustment and preservatives in food processing. It can also be used in soil improvement, feed additives and other scenarios.

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.
