Sapphire blue glass and preparation technology thereof

Abstract

The invention discloses sapphire blue glass which is prepared from glass components and coloring agent components.The glass components comprise, by mass, 70%-80% of SiO2, 1%-2% of Al2O3, 6%-9% of CaO, 0.1%-0.2% of Fe2O3, 1%-2% of MgO, 0.15%-0.25% of SO3 and 13%-18% of R2O; the coloring agent components comprise, by mass, 0.2%-0.3% of Fe2O3, 0-0.2% of CuO and 0.005%-0.02% of CoO.The sapphire blue glass is bright in color, stable in color and luster, nontoxic, odorless, simple in production technology, low in cost and worthy of popularization.

Description

technical field [0001] The invention relates to a glass, in particular to a sapphire blue glass and a preparation process thereof. Background technique [0002] The colored glass wine bottle used in the current wine packaging is to spray a layer of paint of the required color on the surface of the ordinary transparent glass bottle. The transparent glass bottle must be cleaned before spraying, sprayed after drying, and then passed through the electric furnace. After drying at 180-200°C, the required products are produced. The products produced by spraying have the advantage of diversified colors. During the spraying process, a large amount of waste gas, waste residue and waste water are produced, which wastes a lot of manpower, material resources and energy consumption. Moreover, the adhesion of the sprayed layer is poor, the surface strength is low, the paint is easy to fall off when knocked, and it is easy to have wear marks and scratches. Especially after the infiltration ...

[0002] The colored glass wine bottle used in the current wine packaging is to spray a layer of paint of the required color on the surface of the ordinary transparent glass bottle. The transparent glass bottle must be cleaned before spraying, sprayed after drying, and then passed through the electric furnace. After drying at 180-200°C, the required products are produced. The advantages of sprayed products are diversified colors. During the spraying process, a large amount of waste gas, waste residue and waste water are produced, which wastes a lot of manpower, material resources and energy consumption.

Moreover, the adhesion of the sprayed layer is poor, the surface strength is low, the paint is easy to fall off when knocked, and it is easy to appear wear marks and scratches, especially after the infiltration of wine liquid or the erosion of alcohol volatilized gas, the sprayed layer will fall off more seriously.

It brings great loss and harm to spray bottle manufacturers, wineries and consumers, and does not meet the requirements of food safety management
