1250 Mesh Calcium Hydroxide Lime High Purity 98% Calcium Hydroxide Powder

Chemical Information:

Calcium hydroxide (chemical formula: Ca(OH)₂, commonly known as slaked lime or hydrated lime) is a typical inorganic base with stable chemical properties and distinct reaction characteristics. Calcium hydroxide is made from high-quality limestone through precise calcination, fine digestion, multi-stage grinding, and strict purification. It has strong alkalinity, good moisture absorption, stable and non-toxic chemical properties, and the degradation product is calcium carbonate, which is environmentally friendly and harmless.

Core Features & Advantages

- High Purity: 98% high purity, minimal impurities, avoids side reactions, suitable for high-end scenarios

- Ultra-fine Particle Size: Specific surface area over 20 ㎡/g, reaction rate increased by 30%-50%, good dispersibility without agglomeration

- High Whiteness: ≥90 whiteness, no impurity spots, meeting both functional and aesthetic needs

- High Cost-Effectiveness: 20%-30% less dosage for the same effect, desulfurization adsorption capacity 2-3 times that of ordinary products

- Environmental & Safe: Non-toxic and easily degradable, replaceable for highly corrosive lye, reducing governance costs and pollution

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.
