摘要

这是一篇陶瓷及复合材料领域的论文.为了探索玄武岩纤维耐酸碱腐蚀性,分别利用3mol/L硫酸溶液、氢氧化钠溶液浸泡有无浸润剂的玄武岩纤维,并测试了纤维的质量损失率、断裂力保留率及纤维表面SEM.结果表明,随着浸泡时间的增加,在硫酸溶液浸泡下,有浸润剂玄武岩纤维的质量损失率由1.42%增加到7.33%,断裂力保留率由95.34%降至66.49%,无浸润剂玄武岩纤维的质量损失率由3.69%增加到9.40%,断裂力保留率由88.39%降至53.64%;在氢氧化钠溶液浸泡下,有浸润剂玄武岩纤维的质量损失率由0.40%增加到5.41%,断裂力保留率由97.37%降至79.82%,无浸润剂玄武岩纤维的质量损失率由1.50%增加到7.08%,断裂力保留率由93.42%降至69.85%;酸碱腐蚀均造成纤维质量损失,增加纤维表面缺陷,降低纤维断裂力,且相同浓度的硫酸溶液比氢氧化钠溶液,对所用玄武岩纤维的腐蚀更严重.浸润剂对纤维具有保护作用,能减缓酸碱对纤维的腐蚀.

Abstract

This is an article in the field of ceramics and composites.In order to explore the resistance of basalt fiber to acid and alkali corrosion,basalt fiber with or without wetting agent was soaked in 3 mol/L sulfuric acid solution and sodium hydroxide solution,respectively,and the mass loss rate,fracture force retention rate and SEM image of fiber surface were tested.The results showed that with the increase of soaking time,the mass loss rate of basalt fiber with infiltrating agent increased from 1.42%to 7.33%,the fracture force retention rate decreased from 95.34%to 66.49%,the mass loss rate of basalt fiber without infiltrating agent increased from 3.69%to 9.40%and the fracture force retention rate decreased from 88.39%to 53.64%.After soaking in sodium hydroxide solution,the mass loss rate of basalt fiber with wetting-agent increased from 0.40%to 5.41%,the fracture force retention rate decreased from 97.37%to 79.82%,the mass loss rate of basalt fiber without wetting-agent increased from 1.50%to 7.08%,and the fracture force retention rate decreased from 93.42%to 69.85%.Both acid-alkaline corrosion cause fiber quality loss,increase fiber surface defects and reduce fiber breaking force.Sulfuric acid solution with the same concentration corrodes basalt fiber more seriously than sodium hydroxide solution.The soaking agent has a protective effect on the fiber and can slow down the corrosion of acid and alkali on the fiber.
