Research on Explosive Shelf Life Based on Weight Loss Rate for Aging

摘要

To obtain the shelf life of explosive, the aging acceleration at 71 °C was conducted.The experiment data were modified, and nine kinds of fitting model were made for weight loss rate, and the effect was evaluated by the least square method.According to amended Arrhenius model, the change rule of the explosive's weight loss rate with time was got.From t-test, three polynomial model of one element and power exponent model are good.The result shows the method is effective.
