Embodiment Construction

[0018] With reference to the accompanying drawings, the method for manufacturing glass products with ice patterns of the present invention takes out the molten soda lime silica glass or high borosilicate glass from a furnace at 1500°C to 1600°C, and presses it into molding. The pressed glass work piece is taken out of the hot mold, and then the outer surface of the glass work piece is heated by external heating. Generally, the surface is heated to the glass softening temperature, that is, 400-550°C. Place the glass product on the surface of the pre-prepared water-gas mixture at 0℃ to 50℃. The water-gas mixture is obtained by passing gas in the water. The gas pressure is slightly greater than the atmospheric pressure, which can be between 1.05-1.3 atmospheric pressure. , The surface of the glass is cooled in about 2-6 seconds, and the surface of the glass product will soon produce small, irregular ice patterns that burst. Finally, put the glass product back into the furnace at 400°...

Abstract

The method for making ice-patterned glass product includes the following steps: (1), press-forming molten glass, and taking out glass product from hot mould; (2), heating surface of glass product to softening state; (3), utilizing low-temperature water-air mixed liquor to quickly cool the glass product and make its surface produce cracked ice pattern; and (4), annealing and removing stress.

Description

Technical field [0001] The invention relates to a method for manufacturing glass products with ice patterns. Background technique [0002] The ice pattern on the surface of the existing glass products is produced by heating the surface and then placing it in a pre-prepared sink for surface bursting. The glass products produced by this method have the following defects: 1. The appearance of the pattern is rough and unnatural; 2. The lines are unclear, the surface is rough and there are cracked surfaces; 3. The yield is low, the product quality is difficult to control, and mass production is impossible . Summary of the invention [0003] The present invention provides a method for manufacturing glass products with ice patterns. By adopting the present invention, the output of products can be increased, mass production can be carried out, and the appearance effect of ice patterns can be significantly improved, so that the appearance lines are smooth and natural, clear, and the surf...
