Problems solved by technology

The glass bottles for pharmaceutical packaging in developed countries are all made of medium borosilicate glass (with a boron content of about 11%, and an expansion coefficient of about 5.0), also known as: neutral glass bottles. The physical and chemical properties of this medium borosilicate glass are It is recognized as the best glass material for medical packaging in the world; however, the vaccine glass bottles currently on the market cannot solve the shortcomings of too thick thickness, low yield rate, long process and high cost during production.

Abstract

The invention discloses a production process of a medical glass bottle. The method comprises the steps of S1, selecting raw materials, and heating to obtain molten glass paste; S2, shearing the glass paste into blocks by using glass scissors; S3, pressing the blocky glass paste into very thin cake glass by using a specially designed special cake pressing mold; S4, extruding the cake glass by using a primary glass bottle mold and generating a plurality of pieces of cylindrical glass paste; S5, making the cylindrical glass paste into a circular tube shape by using an external mold to form a primary glass bottle; S6, performing closing-in processing on the head part and the tail part of the circular-tube-shaped glass paste by adopting a closing-in jig; and S7, annealing the processed glass bottle by using an annealing furnace, and after the glass bottle is cooled, completing the production and manufacturing of the glass bottle for vaccines. According to the invention, the vaccine glass bottle has the characteristics of lower cost, higher yield, simplicity, convenience, feasibility and obvious effect.

Description

technical field [0001] The invention relates to the technical field of special glass thermoforming technology, in particular to a production technology of medical glass bottles. Background technique [0002] Small glass bottles for vaccines are generally made of neutral borosilicate controlled glass bottles (also known as controlled vials). At present, the material of glass bottles for medical packaging in China is mainly low borosilicate glass (about 7% boron content, about 7.0 expansion coefficient). The physical and chemical properties of this glass bottle are not the best choice for medical glass. The glass bottles for pharmaceutical packaging in developed countries are all made of medium borosilicate glass (with a boron content of about 11%, and an expansion coefficient of about 5.0), also known as: neutral glass bottles. The physical and chemical properties of this medium borosilicate glass are It is recognized as the best glass material for medical packaging in the w...
