摘　　要：通过对基本型接触角测定仪进行改进,增加电热控温装置,使其适宜于高熔点蜡油的进样及测量。利用改进后的接触角测定仪对改性硝酸铵与油相材料包覆后的接触角进行测量,并结合炸药爆炸性能测试,结果表明此仪器可用于表征硝酸铵的改性效果,指导无梯粉状炸药的配方研制。The basic contact angle tester was improved by adding a heating temperature control device in order to make it adapt to high melting point oil. Using this improved tester, the contact angles of modified ammonium nitrate coated by oil were tested. Considering the performance test results of the explosives, the results show that this tester can be used to characterize the modifying effect of ammonium nitrate and guide the composition development of powdery non-TNT ammonium nitrate explosive.
