Magnesium oxide is a white solid, has a common use, to share with you in the building materials industry how to use magnesium oxide?
Fire board: requirements on magnesium oxide: white color, high activity (export board to think of no return halogen, the activity of magnesium oxide must be guaranteed in more than 60%) on magnesium oxide heating speed requirements are not very high, because the fire board is thin, heat dissipation is faster.
Wallboard: the color requirement of magnesium oxide is not very high, to the content, because the goods made to be able to be abundant and magnesium chloride combined, add the strength of wallboard, the level of a lower level than the requirement of fire board.
Greenhouse support: requirements of magnesium oxide is relatively high, because the finished products of the greenhouse support should have flexibility, strength, wind core load, and must not return to the brine (if the salt water from the finished brine back to the farmland will burn seedlings)
Composite duct: the requirements are not too high, the secondary requirements of the whiteness and strength of magnesium oxide.
Magnesite manhole cover: like the greenhouse bracket, because the volume is particularly large and thick, the necessary magnesium oxide content should be average, the activity is good, the manhole cover made with the activity is not high will appear back to halogen, deformation, burst scene!
Activity room, magnesite tile: do not require color, content over 65 on the line, the mesh number is about 120 mesh
Color tiles: do not require color, but activity and content.
