A kind of ion diffusion colorant and its application

Abstract

The invention belongs to the technical field of glass product manufacturing, and in particular relates to an ion diffusion colorant and its application. The present invention adopts the molten salt dipping method, and the original glass sheet or glass product which has been annealed at high temperature is immersed in the molten salt mixed with silver salt and other various salts, so as to reduce the energy consumption of the ion diffusion coloring process, and make Ag The ions can effectively diffuse with the original Na and K ions in the glass to obtain yellow and brown-red colored glass flakes or glass products. The coloring method is simple to operate, has no special requirements on the material of the utensils, and can color glass sheets and glass products of different shapes, sizes and materials at the same time. During the experiment, the temperature is lower, which is beneficial to reduce energy consumption and production cost, and has excellent coloring effect.

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...

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
