Experimental study on the effect of ambient temperature on the water resistance of industrial electronic detonators
YUE Caixin
Abstract：To explore the effect of ambient temperature on the water resistance of industrial electronic detonators,tests are conducted after storage under three ambient temperature conditions:low temperature,high temperature,and thermal shock.The test results indicate that low temperature has no effect on the water resistance of industrial electronic detonators.However,after exposure to high temperature,the injection-molded plug of the industrial electronic detonator shrinks in radial diameter when contacting with water,which reduces the sealing strength against water.It leads to short circuits or damage to the electronic control module,resulting in failure to be detonated properly.Furthermore,as the temperature increases,the radial shrinkage of the injection-molded plug intensifies,thereby increasing the probability of detonator failure.The rapid temperature changes characteristic of thermal shock exacerbate the shrinkage and deformation of the injection-molded plug,further increasing the probability of detonator failure.Measures such as selecting injection-molded plugs made by high-quality PVC material,reducing the clamp diameter,and improving the crimping process,can reduce the impact of ambient temperature on the water resistance of electronic detonators.
