玻璃与水的相互作用过程和机理探索

Interaction Process and Reaction Mechanisms Between Glass and Water

玻璃经常在溶液或者潮湿环境下使用,水的侵蚀会影响玻璃的物理和化学性质,甚至导致玻璃失效。近年来,通过采用多尺度计算机模拟方法,对简单玻璃体系与水相互作用过程和分子尺度反应机理的认识取得了较大进展。本文聚焦石英玻璃、钠硅玻璃和钠硼硅玻璃三个简单的模型玻璃体系,在阐明其耐水性起源的基础上,概述了玻璃与水分子相互作用过程和机理的最新进展,对进一步理解复杂体系玻璃的耐水性和开发新的功能玻璃具有重要的参考价值。

Glass is often used in solution or moist environment,water erosion will affect the physical and chemical properties of glass,and even lead to glass failure.In recent years,great progress has been made in understanding the interaction process and molecular scale reaction mechanism of simple glass systems with water by using multi-scale computer simulation.This paper focuses on three simple models glass systems:quartz glass,sodium silicate glass and sodium borosilicate glass.On the basis of elucidating the origin of its water resistance,the latest progress in the interaction process and mechanism between glass and water molecules were summarized.It has important reference value for further understanding water resistance of complex system glass and developing new functional glass.
