摘要
针对固体推进剂在压延塑化过程中温度过高而容易引起的燃爆问题,提出了远红外测温与喷雾降温。通过试验得出,当药料的温度超过设定值时,经喷雾降温后,药料的温度降低了3~5℃,有效提高了固体推进剂在压延塑化过程中的安全性。在此基础上,研究了在压延塑化过程中,影响药料温度变化的有关因素,得出了结论：随着工作辊转速、工作辊退水温度、压延塑化遍数和硝化棉含量的增加,药料的温度随之升高;随着硝化甘油含量的增加,药料的温度随之降低。
In view of the high temperature and being easy to cause combustion and explosion of solid propellant in the process of rolling plasticizing,the method of far infrared temperature measurement and spray cooling is put forward,it is concluded through experiments that,when the temperature of solid propellant exceeds the set value,then after the spray cooling,the temperature of solid propellant reduces 3-5 ℃,it improves the security of solid propellant in the process of rolling plasticizing effectively.On the basis of this,the effect factors of the solid propellant temperature have been researched during the processing of rolling plasticizing.It is concluded that as the increase of work roll speed,the work roll returning water temperature,the number of rolling plasticizing,and the content of nitrocellulose（NC）,the temperature of solid propellant will increase,but as the increase of the content of nitroglycerine（NG）,the temperature of solid propellant will decrease instead.
