3.5% magnesium oxide suspension how to prepare

3.5% magnesium oxide suspension preparation method:

1, magnesium hydroxide is magnesite as the main raw material in the traditional carbonization kiln for calcination.

2, filtration to remove impurities in the iron hydroxide and then add soluble magnesium hydroxide, and at the same time add the concentration of twenty-five percent to twenty-eight percent of ammonia brine, dilute pyrolysis 1.5 hours later, the generation of magnesium hydroxide.

3, the above magnesium oxide into a slurry material.

4, the magnesium carbonate into the concentration of ninety-eight percent of the acid solution, acid decomposition into soluble magnesium hydroxide, and then in the mixture of acid solution, add the weight ratio of two to three percent of the oxidant to make the solution in the ferrous oxidized into iron hydroxide.
