运用热脱附-气相色谱/质谱(TD—GC/MS)联机技术分析了芦苇秆粉末高压无胶模塑成形复合材料在40、60、90和160℃4个环境温度点的挥发物总离子流图,鉴定了芦苇秆粉末基复合材料在各温度下的保留时间及峰面积,进而评价了芦苇秆粉末基复合材料的环境友好性。结果表明,芦苇粉末基复合材料无胶温压成形工艺过程及其使用过程都具有环境友好性。
Based on the TD-GC/MS online technique,the volatiles total ion current chromatograms of reed powder composites which is formed by warm self bonding compaction have been analyzed at 40 ℃,60 ℃,90℃ and 160 ℃. The retention time and peak area of reed powder-based composites has. been identified at each temperature,then the environmental friendliness of reed powder-based composites has been evaluated. The results show that not only the warm self bonding compaction process of reed powder-based composites has environmental friendliness,but also the preparation and application processes of its products have environmental friendliness.
