Problems solved by technology

The curtain wall glass uses Glauber's salt and reducing agent as clarifier, and uses the gas produced by the clarifier reaction to promote the escape of other gases in the glass melt, thereby reducing bubble defects in the curtain wall glass, but at the same time, there are also the following problems: Sulfur dioxide is mainly generated under the action of the glass melt, and its solubility in the glass melt is very low. After clarification, the sulfur dioxide remaining in the glass melt is easy to form microbubbles, resulting in bubble defects.

Abstract

The invention relates to the field of curtain wall glass, and discloses a curtain wall glass preparation process and curtain wall glass. The preparation process comprises the following steps: weighing silica sand, dolomite, borax, limestone, mica powder, zirconium dioxide, sodium carbonate, mirabilite, carbon powder and titanium dioxide coated and modified ferric oxide; mixing all the raw materials, and grinding into powder; melting, clarifying and homogenizing the powder at 1500-1550 DEG C, heating to 1860-1880 DEG C, stirring for 20-30 minutes, cooling to 1500-1550 DEG C, and stirring for 1.5-2.5 hours to obtain molten glass; feeding the molten glass into a tin bath for molding to obtain molded glass; and annealing the formed glass to obtain the curtain wall glass. According to the invention, while the curtain wall glass is ensured to have relatively high strength, the bubble defect in the curtain wall glass can be effectively reduced by adding the titanium dioxide coated and modified ferric oxide into the raw materials and carrying out heating treatment after clarification.

Description

technical field [0001] The invention relates to the field of curtain wall glass, in particular to a preparation process of curtain wall glass and the curtain wall glass. Background technique [0002] Building curtain wall generally refers to the building envelope or decorative structure composed of supporting structure system and panels, which can have a certain displacement capacity relative to the main structure and does not share the effect of the main structure. The panel materials can be glass, metal, stone Wait. Among them, the building curtain wall with glass as the panel material is the glass curtain wall. [0003] The float process lays the molten glass on the molten tin, and under the effect of surface tension and the viscosity of the glass liquid and the tin liquid itself, a glass liquid layer will be formed. In this process, because the surface of the tin liquid is flat and smooth, Therefore, the finished glass can still maintain a smooth and flat surface witho...
