Influence of Temperature on Impact Sensitivity of Matchhead Composition while in Contact with Different Process Materials

Abstract

This research work aims to understand the influence of temperature (upto 80°C) on the impact sensitivity of matchhead composition with various process contact materials (Steel, aluminium, brass) and to find out the critical temperature for process safety. The BAM fall hammer was modified with a heating element for the measurement of impact sensitivity. The Limiting Impact Energy (LIE) at ambient temperature condition with steel surface on the top and bottom was found to be 3.73J. The lowest critical temperature was found to be 60.14°C for the matchhead composition when it is in contact with steel, which was used as the contact material for both top and bottom.
