Preparation technology of medicinal water-tolerant double-first-class medium borosilicate glass ampoule bottle

Abstract

The invention discloses a preparation technology of a medicinal water-tolerant double-first-class medium borosilicate glass ampoule bottle. A vertical ampoule production line is adopted, and involves working procedures including pipe installation, wiredrawing to prepare a neck, bottom cutting and the like; a thin pipe is arranged below each of a neck preparation station and a bottom preparation station to blow by directly facing a bottleneck, so as to blow out foggy congelation in the bottle; a thin pipe is further arranged on the bottom preparation station to blow to the bottom of the bottle to cool. Two thin pipes are arranged to blow to reduce gas floating in the bottle, the foggy congelation is reduced so as to effectively solve the problem of the insufficient inner surface water tolerance and sheet dropping of the medium borosilicate ampoule bottle, and medicinal safety is improved.

Description

technical field [0001] The invention belongs to the field of ampoule preparation, and relates to a preparation process of a medicinal water-resistant double-grade medium borosilicate glass ampoule. Background technique [0002] In the field of medical packaging, due to the stable performance and good storage effect of ampoule glass bottles, modern ampoule is manufactured by secondary processing of glass tubes, and the material is generally neutral borosilicate glass. Medium borosilicate glass ampoules are usually used to store drugs for injection. Since the borosilicate glass ampoules used in medicine are formed by flame processing during the production process, due to the high temperature of the flame during the flame processing, it is usually found that there is white mist in the bottle during the process of making the neck and bottom. Condensation, these will cause the water resistance of the inner surface of the borosilicate glass ampoule bottle used in medicine to fail...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a preparation process for pharmaceutical water-resistant double-stage medium borosilicate glass ampoule bottles. In this process, a thin tube is respectively set up directly below the stations for making the neck and the bottom to blow air on the mouth of the bottle. The inner mist-like condensation is blown out, and a thin tube is installed at the bottom-making station to blow air on the bottom of the bottle to cool down, reducing the floating of gas in the bottle and reducing the mist-like condensation, thus effectively solving the problem of water resistance on the inner surface of the medium borosilicate ampoule bottle. Insufficient sex and detachment problems, improving the safety of medicine
