The industrial detonator is a main detonating material for blasting engineering, and its function is to generate detonating energy to detonate various explosive, detonating cord and booster tube. The industrial detonator has higher sensitivity to mechanical action, the quality of the shell of the industrial detonator directly influences the safe production and use of the industrial detonator to a certain extent, and if the shell has poor strength, the explosion, semi-explosion or explosion rejection of the detonator can occur when the detonator is shocked, impacted or sparked in the production, storage, transportation and use processes. The bending resistance of the industrial detonator is an important index for representing the sensitivity degree of the industrial detonator to the action of mechanical load, is an important basis for evaluating the dangerous level of the industrial detonator in the production, transportation, storage and use processes, and is an important reference for determining what equipment, method, condition and measure are adopted in the production, transportation, storage and use processes of the detonator. Therefore, it is necessary that the detonator be subjected to a bending test prior to use.
