Abstract

The invention relates to a preparation method of sodium calcium silicate glass bottles. The preparation method specifically comprises the following steps: (1) weighing quartz sand, crushed glass, limestones, sodium carbonate, sodium nitrate, borax, barium carbonate, magnesium carbonate, mullite crystal whiskers, silicon nitride crystal whiskers, cerium oxide powder and selenium powder; and ball-milling and mixing the components to obtain a mixed material; (2) feeding the mixed material into a smelting furnace, wherein the temperature of the mixed material reaches 1570-1600 DEG C, and keeping the temperature for 9-11h; and (3) cooling a glass stock solution to 1320-1350 DEG C, and blowing and forming the glass bottles; converting the glass bottles to an annealing furnace at 420-430 DEG C, keeping the temperature for 80-130min first, then heating the glass bottles to 500-520 DEG C, keeping the temperature for 80-120min, taking out the glass bottles, cooling the glass bottles for 6-9s with a air flow at 35-40 DEG C, and then cooling the glass bottles for 30-50s with a air flow at 9-15 DEG C. The internal stresses in the glass bottles can be removed effectively, and the glass bottles keep relatively good strength, and are good in impact resistance, breakage-proof and stable in chemical property.

Description

Technical field [0001] The invention relates to the technical field of glass, in particular to a method for preparing a soda lime silicate glass bottle. Background technique [0002] Glass bottles are packaging containers for food, beverages and many products. They are widely used. Glass is also a packaging material with a long history. With many packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging. The manufacture of glass bottles usually goes through four processes of compounding, melting, forming and annealing. In the molding process, it is necessary to inject the molten glass stock solution into a molding mold with a water cooling system, and rapidly cool and shape, so that most of the energy is accumulated in the glass bottle body, forming internal stress. If the internal stress is too large, it will be easy Cause the bottle to crack. In order to eliminate internal stress, the glass bottle needs to be annea...
