1: Fireproof board: requirements for magnesium oxide: white color and high activity (if the export board wants to achieve no return to halogen, the activity of magnesium oxide must be guaranteed to be above 60%) The requirements for the heating speed of magnesium oxide are not very high Because the fireproof board is thin, the heat dissipation is relatively fast.

Light burnt powder ingredients

2: Wallboard: The color requirement of magnesium oxide is not very high, but the content is required, because the product made should be able to fully combine with magnesium chloride to increase the strength of the wallboard, and the grade is one grade lower than that required by the fireproof board.

3: Greenhouse support: Magnesium oxide is required to be relatively high, because the finished product of the greenhouse support must have flexibility, strength, wind load, and must not return to brine (if the brine returned from the return of the finished product drips into the farmland, it will burn out seedlings)

4: Composite air duct: The requirements are not too high, mainly the whiteness and strength of magnesium oxide. 5: Magnesium manhole cover: Like the greenhouse support, because the volume is particularly large and thick, the magnesium oxide content must be uniform and the activity is better. The manhole cover made of products with low activity will definitely return to halogen, deform and burst. !

6: Activity room, magnesite tile: no color is required, the content is over 65, and the mesh number is about 120 mesh

7: Color tile: color is not required, but activity and content are required.
