Magnesium Sulfate fireproof door core material is mainly Magnesium Oxide (MgO) and Magnesium Sulfate (MgSO4), Magnesium Sulfate in the air humidity is not adsorbed in the air when the water molecules, in the general environment and wet environment, SO4-2 does not react with our building steel, so the Magnesium Sulfate fireproof door core will not absorb moisture back halogen, will not corrode our common use. Building metal. Therefore, the Magnesium Sulfate fireproof door core has an absolute advantage over the glass panel in moisture absorption, halogenation and corrosion of building metals. The Magnesium Sulfate fireproof door core solves the fundamental problem of moisture absorption and halogenation of glass magnesium plates.

  The Magnesium Sulfate fireproof door core which has solved the problem of back halogen automatically becomes the main filling material of the steel fireproof door. It can fundamentally solve the corrosion resistance and rust prevention of the steel fire door, and the Magnesium Sulfate fireproof door core is a new type of fireproof door core, and its quality characteristics are widely used in various fields.
