Method of producing magnesium hydroxide slurry and magnesium hydroxide slurry

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of magnesium hydroxide slurry which can prevent gelation and hardening of the magnesium hydroxide slurry enough, and the magnesium hydroxide slurry provided with the manufacturing method and removing sulfur oxides in exhausting smoke.SOLUTION: In a manufacturing method of magnesium hydroxide slurry, naphthalenesulfonic acid formaldehyde condensate or salts thereof are added in a step manufacturing the magnesium hydroxide slurry by adding water to light-burned magnesium oxide with not more than 10 μm of mean particle size for hydration reaction.SELECTED DRAWING: None
