Method for making composite type nucleated glass from flyash used in building

Abstract

The present invention relates to a method for making composite flyash building nucleated glass, and is characterized by that in the course of production the nucleating agent beta-CaO. SO2 or microcrystalline kaolin can be added before the flux is water-quenched, also can be added after the flux is water-quenched, the toughening agent is ZrO2 or ZrO2, the flyash can be substituted with industrial wastes and discards material containing SiO2 and Al2O3, and its sandwich layer is filled with colour glass powder, inorganic pigment or light-storing luminescent material, the bottom portion of the melting furnace is equipped with bottom slope with 5-8 deg. and in the course of sintering the base glass, surface layer composite glass and sandwich layer are simultaneously sintered.

Description

technical field

[0001] The invention belongs to the field of engineering material manufacturing, and in particular relates to a method for manufacturing composite fly ash architectural glass-ceramics. Background technique

[0002] Glass-ceramics are polycrystalline solids produced by the controlled crystallization of glass. The meaning of microcrystallization refers to nucleating the nucleating agent introduced into the glass through an appropriate treatment system and triggering crystal growth to form microcrystals. It has a wide range of applications in mechanical engineering, aerospace engineering, nuclear engineering, as well as food, medical and optical fields. For cost reasons, architectural glass-ceramics are mostly made of industrial waste. However, except for the micro-crystalline plates produced by blast furnace slag and copper tailings, which have been used in the construction field, others such as iron tailings, tungsten tailings, gold tailings, lithium The use...
