【摘要】 采用毛细渗透法和Washburn方程测定了六硝基芪、(HNS)、硝基胍(NQ)和吸收药片在10%乙二醇、乙醇、30%乙二醇、水中的接触角,并通过Young方程及表面化学理论计算了它们的表面能及其分量。结果表明,其值与理论计算值相符合,NQ有较高的表面能为58.31 mJ·m-2,其中极性分量占主要成分为54.73 mJ·m-2;HNS的表面能为17.97 mJ·m-2,它的非极性分量与极性分量相当,分别为8.27 mJ·m-2和9.70 mJ·m-2,吸收药片的表面能为21.96 mJ·m-2,非极性分量为17.28 mJ·m-2,极性分量为4.68 mJ·m-2。更多还原

【Abstract】 The contact angles,surface free energies and dispersive,polar component of hexanitrostilbene(HNS),nitroguanidine(NQ) and the paste were determined and were calculated by the wicking permeation method and the Washburn equation.The surface free energy agrees well with the theoretical calculated result.The surface free energy of NQ is 58.31 mJ·m-2 and the dispersive component is the main parting of it.The dispersive component of NQ is 54.73 mJ·m-2.The surface free energy of HNS is 17.97 mJ·m-2.The dispersive component of HNS is 8.27 mJ·m-2.The polar component of HNS is 9.70 mJ·m-2.The surface free energy of paste is 21.96 mJ·m-2.The dispersive component of paste is 17.28 mJ·m-2.The polar component of HNS is 4.68 mJ·m-2.更多还原
