摘　　要：利用锆粉、四氧化三铅作点火药制备防水电点火头,对该电点火头的防水性能、吸湿性能进行实验。实验发现,将电点火头完全浸没在水中7 d仍能正常点火,抗吸湿性能也良好,并通过升降法实验得出其安全电流和发火电流。The waterproof fuse head was prepared by zirconium powder and red lead in this paper,the waterproof property and hygroscopicity of the fuse head were studied.Experiments shows that the fuse head immersed in water for seven days can be ignited normally and the hygroscopicity is performed satisfactorily.And the safety current and firing current of the fuse head is also given by Up-Down method in this paper.
