High specific surface area calcium hydroxide refers to the ratio of the surface area of calcium hydroxide within a certain mass or volume, usually ranging from 40-60m2/g, which is 2-3 times the specific surface area of ordinary calcium hydroxide. Calcium hydroxide with high specific surface area has excellent adsorption performance and reaction activity. Secondly, it also has high purity, high activity, as well as good dispersibility, plasticity, and biocompatibility. In addition, it also has the characteristics of porosity and high utilization rate.

Application:

1. Environmental protection field

Flue gas desulfurization: High specific surface area calcium hydroxide as a desulfurizer can efficiently remove sulfur dioxide (SO ₂) from flue gas and reduce air pollution.

Wastewater treatment: used to adjust the pH value of wastewater, remove heavy metal ions (such as lead, cadmium, etc.), and act as a flocculant to improve wastewater treatment efficiency.

Solid waste treatment: used to solidify hazardous waste and reduce the leakage of harmful substances.

2. Chemical industry field

Production of calcium carbonate: As an intermediate raw material for producing lightweight calcium carbonate, it is widely used in industries such as plastics, rubber, and coatings.

Preparation of bleaching powder: used for producing bleaching powder (Ca (ClO) ₂), applied in industries such as textiles and papermaking.
