摘　　要：研究了固体混合状态下,改性硝酸铵与油相材料包覆后的接触角与表面活性剂添加量的关系,以及表面活性剂添加量与爆炸性能的关系,结果表明两者之间存在一致性,可以用接触角来表征粉状硝酸铵的改性效果。Under solid mixture, the relationships between the contact angle of modified ammonium nitrate coated by oil and surfactant additive amount and between surfactant additive amount and explosive properties are studied. The results indicate that an excellent agreement exists between the two relationships. Thus contact angle can be used to characterize the modifying effect of powder ammonium nitrate.
