Application: Magnesium Oxide Powder 80% can be used in producing Magnesium sulphate. Here comes the productive process:
Reaction formula:
MgO + H₂SO₄ + 6H₂O=MgSO₄.7H₂O
1. Measure the magnesium oxide powder and sulfuric acid proportionally.
2. Add some water in neutralizing tank, slowly adding magnesium oxide powder and Stiring, after that adding sulfuric acid and keep PH=5, Density=1.370g/m³ - 1.384g/m³, Temperature=80℃.
3. Filter the mixture and put it in the crystallizer.
4. Cooled to 30℃ and subjected to centrifugal separation.
5. Put wet material into vibration fluidized bed.
6 .Dry it and get Magnesium sulfate heptahydrate at 50℃-55℃
Magnesium oxide is also used in oil field. Naphthenic acid (NA) has been recognized as one of the major sources of corrosion in oil production and refining. In this study, catalytic decarboxylation of carboxylic acid model compounds and naphthenic acid removal from crude oil were investigated. A metal oxide catalyst, MgO has been developed and its effectiveness in catalyzing decarboxylation reactions involving carboxylic acid compounds such as naphthoic acid has been determined based on the formation of CO2 and the conversion of acid.
In Construction, MgO is used to produce magnesia board. MgO Board is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products. Light bulk loose, white amorphous powder. No smell, no poison. Density 3.58 g / cm 3. Insoluble in pure water and organic solvents, the solubility in water increases with the presence of carbon dioxide. Soluble in acid, ammonium salt solution
Packing: 25kg, 50kg or 1250kg bag all available.
