A facile and efficient method to investigate the effect of the nature of surfactant and continuous phase on the performance of emulsion explosive

摘要

AbstractAn investigation was performed into the performance of emulsion explosive via studying on the storage modulus of its matrix. The experimental results show that there is a tight relationship between storage modulus and the performance of emulsion explosive because both have strong connection with droplet size. A higher G′ represents a superior performance of emulsion explosive. The storage modulus was taken to investigate the effect of the nature of surfactant and continuous phase on the performance of emulsion explosive. It was found that the stronger interaction between surfactant and dispersed phase improve the performance of emulsion explosive. But, the increase of polarity of continuous phase decreased the performance of emulsion explosive.Graphical abstractDue to the tight relationship between G′ and the performance of emulsion explosive, that the VOD increases with the raise of G′, we took the G′ to estimate the effect of surfactant and continuous phase on the performance of emulsion explosive. In four surfactants, the performance of emulsion explosive formed by PIBSA-TEA is best. It might be caused by the stronger interaction between PIBSA-TEA and AN in comparison to other three surfactants. The increase of polarity of continuous phase reduces the performance remarkably because of the reduction in the kinetics of the refinemen
