摘要
对国内生产的3种连续玄武岩纤维的耐高温性能进行了研究。玄武岩纤维单丝拉伸强度表明,随着温度的升高,玄武岩纤维的耐高温性能变差,并且高温处理后质量有所损失。通过对比几种连续玄武岩纤维的质量损失率发现在高温过程中纤维表面的浸润剂也随之分解。显微镜观察纤维形貌发现,700℃高温处理后,3种玄武岩纤维的直径均略有减小,纤维的颜色发生改变。
The high temperature resistance of three kinds of continuous basalt fibers produced in China was studied.The tensile strength of the basalt fiber monofilament indicates that the high temperature resistance of the basalt fiber deteriorates with the increase of temperature,and there was a loss of mass after the high temperature treatment.By comparing the mass loss rates of several successive basaltic fibers,it was found that the percolation on the surface of the fibers breaks down during the high temperature treatment process.Microscopic observation of fiber morphology shows that the diameter of three kinds of basalt fibers decreas⁃es slightly and the color of the fibers changes after 700℃high temperature treatment.
