Abstract

A new type of fire suppressant powders of magnesium hydroxide (Mg(OH)2) modified by DOPO-VTS has been manufactured. And the fire suppression effectiveness and physical-chemical properties were studied in this paper. Three kinds of powders were used to study their fire suppression efficiency through laboratory scale experiments in a confine space of 111m. The physical and chemical characteristics of pure Mg(OH)2 and its modified powder were characterized by thermal gravity analysis (TGA) and X-ray photoelectron spectroscopy (XPS). The results exhibited that these three kinds of powder were all high efficient for fire suppression and the modified Mg(OH)2 powders by added 3% DOPO-VTS was more efficient than the Mg(OH)2 powders added 1% DOPO-VTS and the origin powder. And the modified Mg(OH)2 powder by added 3% DOPO-VTS could release the least CO and decrease the flame temperature sharply. Fire extinguishing and possible fire-suppression mechanisms have also been analyzed from three aspects: chemical inhibition, cooling effect and asphyxiation effect.
