粉状硝铵炸药用木粉的比表面和孔径分布测定

Measurement of the Specific Surface Area and Pore Size Distribution of the Sawdust Used in the Powdery Ammonium Nitrate Explosive

文章用 NOVA10 0 0比表面仪测定了粉状硝铵炸药用木粉的比表面积和孔径分布。结果说明 ,木粉具有较大的比表面积和总表面积以及适中的孔径和孔径分布 ,为木粉具有敏化作用和疏松作用找到了最直接的证据。

In this paper,the specific surface area and pore size distribution of the sawdust has been measured by NOVA1000 specific surface area instrument,which is used in the ammonium nitrate explosive.The results show that sawdust possesses bigger specific surface area and total surface area and appropriate pore size and pore size distribution.It is given proves that the sawdust possesses sensitization and looseness function.
