酸处理和热处理对氧化铝/石英复合纤维性能的影响
Effect of pretreatment and heat-treatment on properties of alumina-silica composite fibers
摘要
Abstract
Boehmite sol was prepared by sol-gel method with A1C13·6H2O, Al powder and H2O as raw materials. The Boehmite sol was coated on the quartz fiber pretreated with dilute sulfuric acid by impregnation method, then dried and heated, finally alumina-silica composite fibers were obtained, and the effect of pretreatment and heat-treatment on its properties was studied. The results show that the best pretreatment conditions is to immerse the quartz fiber in 6% dilute sulfuric acid for 1 h at 98 ℃, which can effectively remove the organic wetting agent on the silica fiber surface and keep higher strength. At 250 ℃ heat treatment temperature, the properties of alumina-silica composite fiber are the best. Compared with the quartz fiber, the tensile strength of the composite fiber is increased by about 1.5 times, and alkali corrosion resistance is increased by about 3 times.关键词
