Teach you how to choose the special fire-resistant phenolic plate _ langfang three friends of insulation materials co. , LTD
want to buy a special fire phenolic board and don't know how to choose? It doesn't matter, langfang sail teach you choose special fire phenolic plate, the following will see together!
。 According to the construction site and the fire endurance requirements special fire use phenolic plate hidden steel structure of the building, to the appearance of the coating quality is not high, should try to use special thick steel structure fireproofing phenolic board. Bare steel space frame, steel roof truss and the roof bearing structure, the rules and regulations of when phenolic composite insulation board in the fire resistance requirements. H, can choose thin coating type or special fire phenolic plate, ultrathin steel structure fireproof limit requirements. H, should choose special fire-resistant phenolic plate thick steel structure.
。 Carefully choose special thin coating of steel structure fire phenolic plate, strictly control the ultrathin steel structure special selection of fire-resistant phenolic board. To strictly control the whole steel structure, especially steel column, steel beam, steel slab and steel ladders used in large public buildings. Steel columns, steel slab and steel insulation board stair evacuation phenolic resin and other major construction should first choose concrete fire protection materials such as steel wire mesh, do have some difficulty, can choose special thick steel structure fire protection, phenolic plate carefully choose special thin steel structure fire phenolic plate, strictly control the ultrathin steel structure special selection of fire-resistant phenolic board. High-rise building steel structure and the multi-storey steel structure building, unfavorable use thin coating type and ultrathin steel structure of special fire phenolic board.
。 Should not be outdoor use inflating special fire phenolic board. Inflating the special fire-resistant phenolic plate used for wood, at first due to poor for outdoor weatherability, easy ageing, peeling, the reliability of the expansion in the humid environment, corrosion problems, and in the high temperature flame barbecue special fire protection in the process of phenolic foam board, resin decomposition to produce smoke and toxic gases, etc. , so if no special measures, in tunnel, and people often stay outdoor buildings, unfavorable use inflating the special fire-resistant phenolic board. Nuclear energy, electric power, petrochemical and chemical industries such as engineering shall be mainly composed of thick type special fire-resistant phenolic board.
