通过对B/BaCrO_4延期药配方及混药方式进行研究,并结合我国工业雷管的实际应用方式,采用铅延期体结构把此延期药装配成导爆管雷管进行测时,考察其延期精度和延期时间;此外,对延期元件进行了0.5a的自然贮存试验,检验其贮存后延期时间与延期精度的稳定性。结果表明:B/BaCrO_4延期药燃速稳定、延期精度高、贮存性能好,在一定范围内,延期时间与延期元件的长度基本为线性关系。
Through the study on the formula and the method of mixing B / BaCrO_4 deferred medicine and the actual application of industrial detonator in our country, this deferred medicine was assembled into the detonator detonator with the lead deferred body structure, and the delaying precision and extension were investigated Time; In addition, the delay element was 0.5a of the natural storage test to test the stability of the delay time and delay accuracy after storage. The results show that the delayed burning speed of B / BaCrO_4 is stable, the delaying precision is high and the storage performance is good. Within a certain range, the delaying time is basically linear with the length of delaying element.
