含RDX单基发射药表面能的实验研究

摘要

鉴于物体的表面性能对物体的物性有很大的影响，采用接触角测量法研究了不同的温度下RDX含量对单基发射药表面能的影响。实验结果表明，单基发射药的表面能随RDX含量的增加而减小，随温度的升高而降低。%The surface properties have great influence on the physical properties of the substances. By measuring contact angle, the influence of RDX content on the surface energy of the single-base gun propellant was studied at different temperatures. The results indicate that the surface energy of the single-base gun propellants decreases with the increasing of RDX content, also decreases when the temperature rises.
