Ion diffusion coloring agent and application thereof

Abstract

The invention belongs to the technical field of manufacturing of glass products, and particularly relates to an ion diffusion coloring agent and application thereof. By adopting a molten salt dippingmethod, glass original sheets or glass products subjected to high-temperature annealing treatment are dipped into molten salt formed by mixing silver salt and other salt, the energy consumption of theion diffusion coloring process is reduced, Ag ions can be effectively diffused with the original Na and K ions in the glass, and yellow and brownish red colored glass sheets or glass products are obtained. The coloring method is simple to operate, special requirements on vessel materials are not needed, and the glass sheets and the glass products with different shapes, different sizes and different materials can be colored simultaneously. In the experiment process, the temperature is relatively low, energy consumption is reduced, the production cost is reduced and an excellent coloring effectis achieved.

Description

technical field [0001] The invention belongs to the technical field of glass original sheet or glass product manufacturing, and in particular relates to an ion diffusion colorant and its application. Background technique [0002] At present, the most widely used preparation methods for colored glass are glass surface diffusion coloring and radiation coloring. Compared with radiation coloring, glass surface diffusion coloring can make the inner and outer surfaces of glass products form a color that is durable and not easy to fade. It has better transparency and flexible production process. Changeable, low colorant dosage, saving production cost. The methods of glass surface diffusion coloring include: surface color coating coloring, surface ion diffusion coloring and surface dyeing method coloring. Compared with coating and dyeing method coloring, when the surface ion diffusion coloring method is used to color glass, ions enter the glass structure and are not easy to wear An...

AI Technical Summary

Problems solved by technology

Compared with the molten salt immersion method, the high-temperature sintering method of smearing slurry on the glass surface has the following disadvantages: the high-temperature sintering method of smearing slurry on the glass surface has strict requirements on the thickness and uniformity of the surface slurry, and the particle size of the slurry directly affects the surface. Uniformity of smearing leads to poor ion diffusion effect, which affects the process and effect of coloring

[0003] The method of coloring the glass surface with metal ion diffusion has a long history, but the actual application technology is not yet perfect
