Abstract
The flame retardant property of aerosols formed from 18 different nanopowders has been studied. The diameter of nanocrystalline powders was determined by XRD and TEM. The concentration of combustible gas was determined by gas chromatography. It was found that ZrO2 nanocrystalline powdered aerosol can effectively retard the burning of CH4. The flame retardation caused by ZrO2 toward the combustion reaction of methane is through an inhibitory mechanism, which was further confirmed by contrasting it with Halon extinguishing agent and flame retardant property of ZrO2-aerosol toward CH3CH2CH3 or CO. The type of nanopowder aerosols as anti-explosion and fireproof agents was researched preliminarily in theory, too. The current ZrO2-aerosol study will find extensive applications in the field of fire-extinguishing and anti-explosion agents used in case of combustible gas.
