LDNP生产工艺改进对其电点火头性能的影响

摘要

分析了点火头基药2,4-二硝基苯酚铅(LDNP)的制备原理,结合制备LDNP的生产工艺,提出了一种改进的LDNP制备方法。该方法加料时,NaOH后于Pb( NO3)2加完,并且在后处理时利用冰醋酸将反应体系pH值调成中性。将采用改进方法制备的LDNP用来生产电点火头,经发火性能等测试,结果表明,该方法有利于提高电点火头机械强度、发火可靠性和一致性。%Preparation principle of 2,4-dinitrophenol lead (LDNP) used as ignition charge of the fusehead was analyzed. Combined with the preparation of LDNP in the factory, an improved method to prepare LDNP was proposed. In this method, NaOH was added after the complete addition of Pb( NO3 ) 2 , and glacial acetic acid was used to adjust pH val-ue in subsequent treatment. Test results show that mechanical strength, reliability and simultaneous of ignition of the elec-tric fusehead made with LDNP by this method are all improved.
