Product Features

The new desulfurizer with ultra-high specific surface area (specific surface area is usually greater than 40 m²/g) can quickly react with other substances when participating in various chemical reactions, greatly shortening the reaction time and improving production efficiency. It is especially suitable for industrial applications with high reaction rate requirements. The product particles are fine and the particle size distribution is uniform. It can achieve good dispersion in different media and avoid agglomeration.

Uses

In the field of flue gas desulfurization, high specific surface area calcium hydroxide can fully contact with acidic gases such as sulfur dioxide in flue gas with its huge specific surface area, significantly improve reaction efficiency, quickly absorb acidic substances, reduce the content of flue gas pollutants, and help coal-fired power plants, industrial boilers, etc. to achieve efficient desulfurization and meet strict environmental emission standards; 

In sewage treatment, it can be used as an efficient neutralizer and precipitant to quickly adjust the pH value of sewage, and react with heavy metal ions to form precipitates, effectively remove harmful substances in sewage, and achieve sewage purification and standard discharge. 

In the production process of polymer materials such as rubber and plastics, high specific surface area calcium hydroxide, as a functional filler, can be evenly dispersed in the material system, produce good interface effects with polymers, and enhance the mechanical properties of the material, such as improving the wear resistance of rubber and the rigidity and impact resistance of plastics; 

In the coating industry, it can be used as a body pigment to improve the suspension stability, hiding power and weather resistance of coatings, and improve the quality of coating products. In the pharmaceutical field, it can be used to prepare pharmaceutical excipients, calcium agents, etc., to meet the special requirements of the pharmaceutical industry for high quality and high activity of raw materials.
