DisadvantagesFirst, the current national standards, such as "Architectural Design Fire Code", "High-rise Civil Building Design Fire Code", "People's Air Defense Engineering Design Fire Code" and other codes are only some principle provisions, can not well guide the design, construction and fire supe

3 Combustion methodCombustion method is a method of synthesizing materials by combustion of precursors. When the reactants reach the ignition temperature of the exothermic reaction, ignition in some way, the subsequent reaction that is maintained by the heat released, the combustion products are the

1 high-temperature solid-phase methodThe use of high-temperature solid-phase reaction method for the preparation of long afterglow materials is a more traditional method, this method is more widely used. In general, the general operation of the solid-phase reaction is to solid powder as raw material
