Will the active content of Magnesium Oxide MgO affect magnesium building materials
The most suitable Magnesium Oxide MgO content of Magnesium Oxide MgO products used in general magnesium building materials is 85%~87%, and the active Magnesium Oxide MgO content is 63%~65%. If it exceeds this range, it will affect the product. The effect of Magnesium Oxide MgO active content on the product is as follows:
1. Influence on the return of halogen. When the active Magnesium Oxide MgO content in Magnesium Oxide MgO is less than 60%, due to the poor ability to bind magnesium chloride, magnesium chloride will be in serious excess, and the excess magnesium chloride will absorb moisture and reach a saturated state, and it will return from the product to the surface of the product and condense. For water droplets, that is, return to halogen.
2. Influence on strength and water resistance. The content of active Magnesium Oxide MgO in Magnesium Oxide MgO is low, and the content of sintered powder, magnesium carbonate and hydrogen Magnesium Oxide MgO is high. This inactive component cannot form a 5:1:8 phase and is an ineffective component. As a result, the amount of 5:1:8 phase is insufficient, and the strength and water resistance of the product are reduced.
