建筑装饰微晶玻璃板中应力产生与形变关系分析

Analyses on Inter-Stress and Deformation of Glass-Ceramic Plate for Building Decoration

CaO-Al2O3-SiO2系统微晶玻璃作为微晶玻璃中的一个新品种,具有非常鲜明的特点,并得到广泛的应用。在微晶玻璃的生产中,微晶玻璃板在由玻璃颗粒烧结、晶化以后会出现板面变形的现象。大多数的板面变形与微晶玻璃装饰板内的结构应力有关。本文讨论了CaO-Al2O3-SiO2系统微晶玻璃中形变与内应力产生的原因,这将对微晶玻璃的生产提供一定的参考。

CaO-Al_2O_3-SiO_2 system glass-ceramic is a new building decorating material. It has very distinct characteristics and has been now widely used. In the glass-ceramic production process, glass-ceramic plates often deformed after glass powder was sintered and crystallized. But most deformation of the plates is related with stress in glass-ceramics. In this paper, the reason of deformation and inter-stress is discussed, this will be of benefit to the production of building decorating glass-ceramic.
