Calcium hydroxide with high specific surface area uses calcium oxide as raw material, adds functional composite additives, and is produced by a specific process. A large number of cavities and wrinkles are formed in the structure, which is different from the traditional particle structure. The specific surface area is 3 times that of ordinary calcium hydroxide. times, so in terms of gas adsorption, reactivity.It has incomparable advantages in fluidity and reaction speed. In addition, according to the user’s desulfurization needs, the catalyst can be enhanced to ensure the desulfurization effect.
High specific surface area calcium hydroxide offers several advantages in terms of its performance compared to traditional forms of calcium hydroxide. Some of the key performance benefits of this material include:
