    摘要:

    为降低α-AlH3静电感度, 选用硬脂酸 (SA) 作为包覆材料, 采用溶剂-非溶剂法对α-AlH3进行表面包覆。通过傅里叶变换红外光谱 (FT-IR)、X射线衍射仪 (XRD)、X光电子能谱 (XPS)、元素分析和扫描电子显微镜 (SEM) 对包覆前后α-AlH3的结构和形貌进行表征。按GJB5891.27-2006采用静电火花感度仪JGY-50Ⅲ对包覆前后样品的静电感度进行测试。结果表明:硬脂酸在α-AlH3表面形成均匀完整包覆层, 包覆后的α-AlH3样品晶体结构和形貌均未发生变化, E50由未包覆前的367 mJ降低至测试上限5390 mJ时未见发火, 包覆使其静电感度降低。

    Abstract:

    To reduce the electrostatic sensitivity of α-AlH3, α-AlH3 was coated by the solvent-nonsolvent method using stearic acid (SA) as coating material. The crystal structure and morphology of samples before and after coating were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), elemental analysis and scanning electron microscopy (SEM). The electrostatic sensitivity of α-AlH3 samples before and after coating was measured by JGY-50Ⅲ type static spark sensitivity tester according to GJB5891.27-2006 method. Results show that a complete, uniform coating layer of SA is formed on the surface of α-AlH3. The crystal structure and morphology of the sample after coating are not changed. When the spark energy required for 50% initiation probability (E50) decreases from 367 mJ before coating to test limit 5390 mJ, the fire does not occur. The coating makes the electrostatic sensitivity reduce.
