摘要:利用比表面积和孔径分析仪,研究分析脱气条件、计算模型以及吸附压力等气体吸附参数对纳米网格三氨基三硝基苯(n-TATB)比表面积的影响。结果表明:适当的脱气条件有助于加快n-TATB表面吸附杂质及水分的挥发;Brunauer-Emmetr-Teller计算模型适合于n-TATB比表面积分析,最佳分析相对压力范围为0.05~0.25;n-TATB是一种含有少量微孔和介孔的裂隙大孔材料。

Abstract: The influence of degassing method , calculation model , and adsorption pressure on the specific surface area tested result of nano-grid triaminotrinitrobenzene (n-TATB) was researched by a surface area and pore size analyzer . The results show that the proper degassing method can accelerate the volatilization speed of foreign substance and water absorbed by the surface of n-TATB . Brunauer - Emmetr -Teller calculation model is suit for the specific surface area analysis of n-TATB and the optimal test relative pressure is in t he range of 0.05 to 0.25. n-TATB is a kind of slit-macropores material including some micropores and mesopores.
