Processing technology of glass bottle

Abstract

The invention discloses a processing technology of a glass bottle. The processing technology comprises the following steps: (1) treating broken glass; (2) mixing raw materials: weighing the following raw materials in parts by weight: 50-80 parts of powder particles, 40-60 parts of calcite, 30-40 parts of albite, 10-20 parts of fluorite, 5-10 parts of borax, 2-6 parts of sodium carbonate, 1-5 parts of table salt, 0.1-0.8 part of magnesium sulfate, 0.01-0.05 part of cobalt powder and 0.6-1.8 parts of a compound clarifying agent, and evenly mixing and stirring the weighed raw materials to obtain a mixture; (3) molding by sintering; (4) annealing; (5) performing plate-making and printing; (6) tempering the glass bottle. The processing technology of the glass bottle can eliminate the pressure in a glass bottle body, thus avoiding the phenomenon of bursting caused in a production process and the phenomenon of cracking caused in a later use process; furthermore, the processing technology simplifies a coating operation process and increases the tightness of a coating layer; the glass bottle produced by using the processing technology is bright in color, high in light transmittance and long in service life.

Description

technical field [0001] The invention relates to the technical field of glass bottles, in particular to a glass bottle processing technology. Background technique [0002] The manufacture of glass bottles usually goes through four processes of batching, melting, forming and annealing. During the molding process, it is necessary to inject the molten glass stock solution into the molding mold with a water cooling system, and rapidly cool the molding, so that most of the energy is stored in the glass bottle body, forming the so-called internal stress. If the internal stress is too large, it is easy to Cause the bottle body to crack, and to eliminate the internal stress, it is necessary to anneal the glass bottle to release the internal stress in the glass bottle body. [0003] The current annealing temperature is usually controlled between 300 and 400°C. In the actual annealing process, especially in the annealing process of high-transparency glass bottles, the internal stress ...

[0003] The current annealing temperature is usually controlled between 300 and 400°C. In the actual annealing process, especially in the annealing process of high-transparency glass bottles, the internal stress in the bottle body cannot be completely eliminated, thus affecting the glass bottle. quality and safety
