Research Progress on Physical Tempered Glass

物理钢化玻璃因具有高强度、高热稳定性、高安全性和低成本等优势而被广泛应用于建筑幕墙、高档家具、汽车风挡和液位计等领域。目前,物理钢化玻璃的研究主要集中在:(1)探究玻璃物理钢化机理,揭示物理钢化增强的结构起源,为实现玻璃更高力学性能和服役安全性提供理论指导;(2)优化物理钢化工艺参数,借助仿真模拟手段,进一步提高玻璃强度和安全性,实现玻璃物理钢化强度和破碎颗粒度的自主设计;(3)针对物理钢化玻璃安全应用的自爆顽症和钢化强度衰减现象,揭示钢化玻璃自爆机制和强度衰减规律,建立钢化玻璃自爆和强度衰减等关键性能评测方法。本文基于以上三个方面综述了物理钢化玻璃的国内外研究进展,并展望了其发展趋势。

Physical tempered glass is widely applied in curtain walls, high-end furniture, automobile windshields, and liquid level meters owing to its advantages of high strength, outstanding thermal stability, high safety, and low cost. At present, the research on the physical tempered glass mainly focuses on (i) exploring the mechanism of physical tempering and revealing the structural origin of physical strengthening to establish a theoretical basis for achieving improved mechanical properties and greater service safety of glass;(ii) optimizing the tempering process parameters to improve the glass strength and safety through simulations and to realize the independent design of physical tempering strength and broken particle size of glass;(iii) understanding the spontaneous cracking mechanism and establishing the strength attenuation law and evaluation met- hods , aimed at overcoming the spontaneous cracking and strength attenuation phenomena that restrict the safe application of physical tempered glass. Based on the above three aspects, the research progress of tempered glass at home and abroad are summarized.
