Yellow opal glass material, and preparation method and application thereof

Abstract

The invention especially relates to a yellow opal glass material, and a preparation method and application thereof, belonging to the technical field of yellow opal glass. The yellow opal glass material comprises the following components by mass percentage: silicon dioxide, sodium oxide, potassium oxide, zinc oxide, boron oxide and calcium fluoride, with the balance being a coloring agent. The preparation method comprises the following steps: 1) melting: mixing the components and melting the mixed components into glass liquid; 2) clarification and molding: clarifying and homogenizing the glassliquid; and 3) annealing and color development: placing the homogenized glass liquid in a mold which is located at the front end of a mesh belt annealing traction furnace, subjecting the outer surfaceof the glass liquid to cooling and preliminary molding, then allowing the formed glass to enter an annealing furnace for continuous annealing under the traction of a rear-end mesh belt, and after annealing and cooling in the furnace, allowing the glass to enter a color developing and annealing furnace with precise temperature control for continuous annealing and color development. The preparationmethod of the invention realizes the continuity of production process, reduces the stress non-uniformity of the glass material, and is a stable preparation technology for the yellow opal glass material.

Description

technical field [0001] The invention relates to the technical field of yellow protein glass, in particular to a yellow protein glass material and its preparation method and application. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Yellow is the most strictly controlled glaze color by the royal family, and golden yellow is called the color of supremacy. Yellow protein glass in the Ming and Qing dynasties was only used by the royal family. In ancient yellow protein glass, the preparation technology was rigorous, and the standards for color and purity were very strict. Its yield rate was extremely low, and the firing history was interrupted several times aft...

AI Technical Summary

Problems solved by technology

[0004] After testing and research of the present invention, the preparation method adopted in the above-mentioned patent documents still has some deficiencies: the melting process of molten glass is carried out in a crucible, which is unfavorable for the homogenization of molten glass and does not possess the continuity of the production process; The coloring mechanism of gold belongs to colloidal coloring. The color tone after color development is affected by the composition of the glass, the melting process and the annealing process, especially the color development process. Certain sedimentation will affect the uniformity of the color of the glass material; the prepared matrix material needs to be heat-treated separately in the later stage to complete the annealing and color development process, and the opacity degree of the material during the color development process has a certain degree of instability
