摘要
为了研究粘合剂对钨系延期药燃速的影响,用硝化棉和聚四氟乙烯对相同配方的延期药分别进行造粒,测定了这两种延期药在常温(20℃)和高温(120,160,180℃)下的延期时间和燃速,结果表明,以硝化棉为粘合剂造粒的延期药(A)在上述温度下的平均燃速分别是以聚四氟乙烯为粘合剂造粒延期药(B)平均燃速的2.2倍、2.3倍、3.3倍和4.8倍,并且延期药B的燃速随温度升高而加快的幅度较小;延期药A在180℃的延期时间仅为常温的36%,延期药B在180℃的延期时间是常温的77%。
To study the effects of the binding agents on the burning rate of the tungsten delay composition, two delay compositions in bound form were made with nitrocellulose and Teflon separately. An experiment on the two delay compositions was carried out and their delay time at room temperature and high temperatures（ 120, 160, 180℃ ） were obtained. The results show that the burning rate of the composition with nitrocellulose as binding agent is much faster than that of the composition with Teflon as binding agent. When the temperature rises, the burning rate of the composition with nitrocellulose as binding agent increase rapidly while the burning rate of the composition with Teflon as binding agent does slowly.
