Polymer combustion and smoke generation mechanism

The combustion of the ruthenium polymer is generally caused by the external heat to decompose the flammable gas, and it is violently oxidized and ignited by mixing with the oxygen in the air. The combustion process generally includes steps of heating, melting, depolymerizing or decomposing, oxidizing ignition, burning, and retarding.
Some terpolymer grommets generate a lot of fumes when burned, which is extremely detrimental to fire and escape. The fuming properties of the terpolymer during combustion are closely related to the molecular structure, additives and combustion environment of the terpolymer. The most representative mechanism for the generation of black smoke when the ruthenium polymer is burned is the carbon double bond polycondensation mechanism. That is, the combustible gas generated by the decomposition generates an aromatic or polycyclic ruthenium molecular compound by polymerization, and further polycondenses and graphitizes to form carbon fine particles, and is mixed into the gas to form black smoke.
