It is believed that magnesium hydroxide is very familiar to everyone. It is a colorless six square column crystal or white powder. It is widely used in many fields. Recently, some people call to consult the steps of magnesium hydroxide, so this is a detailed introduction.
1. Magnesium hydroxide is made by calcining of magnesite as the main raw material in the traditional carbonated kiln.
2, after removal of impurities in the filtration of ferric hydroxide adding soluble magnesium hydroxide, and adding concentration of twenty-five percent to twenty-eight ammonia, one point five hours after dilution pyrolysis, generation of magnesium hydroxide;
3, the aforementioned Magnesium Oxide is made into slurry.
4, the magnesium carbonate into the concentration of acid solution ninety-eight, after acid hydrolysis into soluble magnesium hydroxide in the mixed acid solution is added in the weight ratio of two percent to three of the oxidant solution was oxidized into ferric iron;
5, the slurry is put into the carbonization tower to make the slurry carbonated into magnesium carbonate.
The above is the steps of the ingredients of magnesium hydroxide, hoping to help you.
