Problems solved by technology

In terms of glass melting process, the energy consumption of the traditional glass melting process realized by fuel accounts for the total energy consumption of the entire industry. The method of using industrial microwave energy for thermal energy conversion, through the design of raw materials and auxiliary heat materials, can realize overall heating, separation Stage melting, clarification, stirring, removing bubbles and other functions, the use of base-colored golden yellow glass plated mirror, not only bright color, elegant, luxurious, strong mirror effect, the whole glass is golden yellow, but they can only be produced on a small scale, and Its products have no golden yellow feeling, its color is only general yellow, and the color purity is also low, so it is difficult to meet market requirements

Embodiment 1

[0015] The glass in this embodiment consists of the following raw material components: SiO 2 50%, B 2 o 3 35%, BaO10%, MgO8%, Na 2 O5%, Al 2 o 3 3% and containing Fe 2 o 3 0.5%, Cr 2 o 3 1.0%, Nd 2 o 3 1.5%, Eu1% and Mn1% colorant 5%.

[0016] The melting steps of above-mentioned glass are as follows:

[0017] 1), select raw materials, carry out raw material mixing according to weight percentage;

[0018] 2) The mixed raw materials are melted in a high-temperature industrial microwave oven with a frequency of 2.45 Hz, and the glass melt melted by microwaves at high temperature is poured into a preheated mold for molding, and then placed in a heating furnace for annealing to obtain luminescence Glass.

Embodiment 2

[0020] The glass in this embodiment consists of the following raw material components: SiO 2 40%, B 2 o 3 30%, BaO5%, MgO7%, Na 2 O3%, Al 2 o 3 1% and containing Fe 2 o 3 0.1%, Cr 2 o 3 0.5%, Nd 2 o 3 0.8%, Eu0.1% and Mn0.3% colorant 2%.

[0021] The melting steps of above-mentioned glass are as follows:

[0022] 1), select raw materials, carry out raw material mixing according to weight percentage;

[0023] 2) Melting the mixed raw materials in a high-temperature industrial microwave oven with a frequency of 5.25 Hz, pouring the microwave-melted glass melt at high temperature into a preheated mold for molding, and annealing in a heating furnace to obtain luminescence Glass.

[0024] It can be seen from the above examples that the product produced by the present invention not only has all the advantages and characteristics of glass, but also has a golden color, elegant and luxurious, and also overcomes the disadvantages of ordinary glass discoloration and darkenin...

Abstract

The invention discloses lead-free colored glass and its melting process. The glass is composed of the following raw material components: SiO2, B2O3, BaO, MgO, Na2O, Al2O3 and colorant; the melting steps of the glass are as follows: 1), select raw materials, mix raw materials according to the weight percentage, 2), microwave the mixed raw materials, and after heat treatment, obtain luminous glass; Disadvantages of discoloration and darkening under high-energy radiation, reducing ultraviolet radiation, no crystallization during glass production, stable luminous performance, energy saving in microwave melting process, and easy control of melting process parameters.

Description

technical field [0001] The invention relates to glass, in particular to lead-free colored glass and its melting process. Background technique [0002] With the continuous improvement of people's living standards, people's pursuit of various decorative effects is getting higher and higher and more abundant. Glass has been widely used because of its high visible light transmittance. In terms of glass melting process, the energy consumption of the traditional glass melting process realized by fuel accounts for the total energy consumption of the entire industry. The method of using industrial microwave energy for thermal energy conversion, through the design of raw materials and auxiliary heat materials, can realize overall heating, separation Stage melting, clarification, stirring, removing bubbles and other functions, the use of base-colored golden yellow glass plated mirror, not only bright color, elegant, luxurious, strong mirror effect, the whole glass is golden yellow, bu...
