Problems solved by technology

But so far, the relevant domestic standards for fire door core panels are still blank, and manufacturers only follow the descriptions of fire door filling materials in "Fire Door GB12955-2008", except that the materials must meet the requirements of flammability and non-combustibility (A1 grade ) and smoke toxicity AQ1 two mandatory conditions, materials need to meet environmental protection requirements, use of degradable materials, there are no clear regulations on more materials and physical and chemical indicators, process indicators, which makes the door panel manufacturers in the product standard There is a large room for maneuverability in the quality control and quality control standards, resulting in the phenomenon of uneven products and shoddy products in the industry.
[0003] The existing door core board materials are mainly expanded perlite boards and magnesite fireproof door core boards, which have low mechanical strength, poor fireproof and waterproof performance, high loss on ignition rate, and boards are prone to problems such as pulverization and mudification, and Existing fire door core panels have poor thermal insulation and sound insulation, do not have a certain function of electromagnetic shielding, and have relatively insufficient functionality
