Abstract

Abstract

Magnesium powder, as a commonly used metallic material, poses a significant explosion risk during its production process, necessitating the urgent development of efficient and targeted explosion suppressants. In this study, different types of bimetallic supramolecular compound suppressants were successfully synthesized via the coprecipitation method, and their suppression effects on magnesium powder explosions were investigated using Hartmann tube experiments. It was found that the bimetallic supramolecular compounds exhibited superior explosion suppression performance compared to the traditional suppressant sodium bicarbonate. Moreover, when the metal cations were identical, carbonate ions demonstrated better suppression efficiency than chloride ions. The suppression effectiveness followed the order: CaFe-carbonate > CuAl-carbonate > MgAl-carbonate > CaFe-chloride > ZnCr-carbonate > MgAl-chloride materials. The suppression mechanism was identified as a combination of endothermic decomposition, physical encapsulation, inert gas dilution, and synergistic scavenging of key free radicals by metal cations and interlayer anions, thereby achieving a dual physical–chemical explosion suppression effect. This study compares the suppression performance of different bimetallic supramolecular compounds on magnesium powder deflagration, offering new insights for the safety protection against accidental magnesium powder explosions.
