【摘要】 本文研究了 TiO₂对国内外抗碱玻璃纤维中应用最广泛的 SiO₂-ZrO₂-Na₂O 系统玻璃耐碱性的影响。应用分光光度法分别测定了玻璃中三种主要氧化物siO₂、TiO₂和 ZrO₂转入 NaOH 侵蚀液中的量。讨论了 ZrO₂、TiO₂提高玻璃耐碱性的原因。结果表明,TiO₂具有耐碱性,三种主要氧化物的耐碱性序列为 ZrO₂>TiO₂>SiO₂。但当 TiO₂引入玻璃中将促使 SiO₂由玻璃向 NaOH 侵蚀溶液转入量的增加。使试样总失重略有增加。更多还原

【Abstract】 This paper is a study on the effect of the TiO₂ on alkaline durability ofalkali-resistant fiberglass in SiO₂-ZrO₂-Na₂O system which has wide use at homeand abroad.The amounts of three principal oxides,SiO₂ TiO₂ and ZrO₂,of theglass which dissolved from the glass to NaOH attaching solution have been deter-mined respectively by the spectrophotometric method.We have had a discussionon the effect of ZrO₂,TiO₂ in the increment of alkaline durability of the glass.The results state that TiO₂ has alkaline durability,and the order of alkalinedurability of three principal oxides is ZiO₂ TiO₂ SiO₂.But when TiO₂ is incor-parated into the glass the amount of SiO₂ which dissolved from the glass toNaOHattacking solution can increase.It causes the total weight loss of the sample toIncrease slightly.更多还原
