Повышение эксплуатационных свойств неорганических стекол выщелачиванием кислыми газами [Articol]

Abstract

Thermochemical treatment by gases reagents in laboratory experiments increases water resistance of glass in 5 times, acid resistance – in 7 times, alkali resistance by 30 %, mechanical strength by 70 %, impact strength by 50 %, thermal stability and microhardness by 15 %. In industrial conditions the treatment with fluoride- and chlorine-containing reagents of industrial glasses for different purposes improves its chemical resistance by 1-2 orders, while the mechanical strength of glass increases by 30 %. Modification of sheet glass surface in industrial experiments is followed by an increase of its water resistance in 9 times, at this central symmetrical flexural strength grows by 30 %, the impact of strength increases by 20 %.
