Ice fire board is a special customized high-pressure inorganic cement reinforced fiberboard as the base material. After special treatment, the decorative paper is impregnated with resin adhesive, that is, the impregnated paper. After high temperature and high pressure, the base material layer and surface layer can achieve the effect of molecular mutual penetration and become an integrated material. The stress effect is basically zero, and the deformation rate of the product can reach 100%, The quality stability can reach 100%.
