摘要
本文研究了Pb3O4-Si延期药的基药配比、各组分含量以及储存时间对燃速和秒量精度的影响。结果表明:基药配比在2.0:1附近时燃速稳定,秒量精度较高;缓燃剂Cy加入后各组分含量变化对燃速影响较大,但对秒量精度影响不大;随着储存期的延长延期药秒量精度变差。
The effects of the ratio of basic drug,content of the components and storage time on the change of delay time and accuracy about silicon type delay composition are studied in this paper.The results show that：a stable burning rate and high delay accuracy can be achieved when the proportion of Pb3O4 to Si is about 2.0：1;the change of the content of the components has a great effect on the burning rate but a little on the delay accuracy adding the delayer Cy into the ingredients;the delay accuracy becomes lower as the storage time is longer.
