【摘要】 采用2.0mol/L的HCl及NaOH溶液为腐蚀介质,在60℃条件下处理玄武岩纤维纱线,研究玄武岩纤维纱线的耐酸/碱腐蚀性能及其腐蚀机理。结果表明,经酸与碱处理后纤维纱线的断裂强度总体上均呈下降趋势,只是下降的规律有所不同。酸与碱处理的纱线表面腐蚀程度不同,且表面的各元素含量也有不同幅度的降低,促使表面处理剂的相对含量增大。另外,碱腐蚀后结构中还产生了羟基(-OH)官能团,因此玄武岩纤维纱线的耐酸性能强于耐碱性能。更多还原

【Abstract】 Basalt fiber yarns were treated in 2.0mol/L NaOH for different times at 60 ℃respectively,to evaluate their properties of corrosion resistance and mechanism in acidic or alkaline environments.The results show that fracture strength generally decrease after treated in acid and alkali solution,just a bit different of the decline curves.The degree of surface corrosion treated in acid and alkali solutions are not the same,and the contents of surface elements decrease more or less,leading to a rise in the relative content of surface treatment agent.Besides,the structure of-OH appears on alkali treated sample,therefore the acid resistance of basalt fiber yarn is better than its alkali resistance.更多还原
