Explanation
Also known as lead styphnate, with a molecular weight of 468.30. Lead styphnate is one of the most widely used single compound primary explosive. Its normal salt appearance is yellow or orange prismatic crystals, belonging to the monoclinic system. The peak decomposition temperature is 284 ° C (10 ° C/min). Hygroscopicity: 0.05K moisture absorption at 2.5C and 100% relative humidity; At 30 ° C and 90% relative humidity, the moisture absorption is 0.02%. The 5s explosion tcmperature is 282 ° C. The limit charge of detonating loosely packed PETN is 0.55g. It can hardly detonate other military explosive alone. The specific volume of explosion is 368mL/g, and the detonation velocity is 5200m/s (impact sensitivity: upper limit 36cm, lower limit 11.5cm (400g drop, 20mg sample); 17cm (10% explosion, 2kg drop hammer, 20mg sample). Friction sensitivity I degree: 70% (0.6MPa. 80 ° swing angle, 10mg sample).
