| 摘 要： | 采用两种方法去除石英纤维表面的浸润剂,一种是热处理,另一种是有机溶剂与热处理相结合。比较石英纤维处理前后失重变化,通过SEM、XPS表面形貌和成分变化,得出石英纤维的表面处理,有机溶剂浸泡与高温处理相结合优于单纯的高温处理。采用不同的升温速率对石英纤维进行热处理,结果表明：升温速率越低,石英纤维的机械强度损失越大。

| Abstract: | This study investigated two methods of eliminating the agents on the surface of silica fibers, compared the losing of disposed silica fibers with the original fibers, analyzed the effects by SEM and XPS. The results show that organic solvent combination of treatment is better method. The tensile strength decreases with declining rate of heating. |
