硅烷处理
With the alkali treatment time and alkali concentration increasing, the tensile breaking strength of the yarn increased first and then decreased. After the silane coupling agent treatment, the tensile breaking strength of the yarn was improved.
随碱处理时间的增加以及碱浓度的提高,黄麻纱线的力学性能先增大后减小;经偶联剂处理以后,黄麻纱线的断裂强度有所提高。
Results indicated that the water diffusion speed in adhesive/ c-c composites joints treated by sand paper was faster than that treated by chemical oxidation and by silane couple agent treatment.
结果表明,经偶联剂处理的碳/碳复合材料耐久性能要好于化学氧化和砂纸打磨处理,这与剪切强度测试结果相一致。
