[0021] Example
[0022] An inorganic fireproof insulation board, as shown in the attached drawings, from top to bottom are a hollow ceramic bead surface layer 3, a glass fiber mesh cloth layer 4, an expanded perlite composite layer 5, a glass fiber mesh cloth layer 6 and a hollow Ceramic bead bottom layer 7.
[0023] Several pits 2 are provided on the upper surface of the hollow ceramic bead surface layer 3 , and several grooves 8 are provided on the outer surface of the hollow ceramic bead bottom layer 7 . In this embodiment, the purpose of the grooves 2 is to fix the anchors during installation; the purpose of the grooves 8 is to prevent slippage when bonding the wall, and the arrangement is much denser than that of the grooves 2 . The upper surface of the hollow ceramic bead surface layer 3 and the lower surface of the hollow ceramic bead bottom layer 7 are respectively provided with non-woven fabric layers 1 and 9 made of non-woven fabrics. processed.
