发泡条件与09－Ⅱ浆状炸药爆轰感度的关系研究

A Study of the Relationship between 09-ⅡSlurry Explosive's Detonation Sensitivity and Foaming Conditions

０９－Ⅱ浆状炸药是一种利用废火药作敏化剂和含能添加剂的浆状炸药，这类炸药爆轰感度较低。该文以实验为基础，研究了发泡条件与０９－Ⅱ浆状炸药中敏化气泡数、爆轰感度之间的关系，这些条件包括发泡剂含量、发泡剂及交联剂的加入次序和发泡温度。文中提出了有利于提高这种浆状炸药爆轰感度的发泡条件是，（１）发泡剂含量为外加０．２％～０．３％；（２）泡剂与交联剂同时加入到炸药体系中；（３）发泡温度在４５℃左右。

The 09-Ⅱslurry explosive is a sort of slurry explosive in which waste single-base propellant is used as sensibilizer or energetic additive and has less sensitive to det-onation. Based on experiments,the relationship between foaming conditions and quantityof sensitized bubble in 09-Ⅱslurry explosive or detonation sensitivity of 09-Ⅱslurry explosive is studied.Foaming coriditions include the percentage of foam beater,the addingprocedure of foam beater and cross linker and foaming temperature,Also,to improve thisexplosive,s detonation sensitivity,the proper foaming conditions are proposed,that is(1)The percentage of foam beater is 0.2%～0.3%;(2)Foam beater and cross linker areadded into explosive system at the same time;(3)Foaming temperature is at about 45 ℃.
