Embodiment 1

[0033] formula:

[0034] Contains the following chemical composition in mass percent: SiO 2 75.16%, Al 2 o3 5.14%, B 2 o 3 10.97%, K 2 O 0.044%, Na 2 O 7.07%, CaO 1.31%, MgO 0.031%, BaO 0.098%, and Fe 2 o 3 0.028%, less than 100% are unavoidable conventional impurities.

[0035] Preparation:

[0036] The method includes the following steps: (1) forming a medicinal neutral borosilicate glass tube through a forming machine; (2) annealing the formed glass sleeve in an electric annealing furnace; (3) performing an external appearance on the glass sleeve Inspection; (4) Final packaging and storage.

[0037] Among them, the molding machine in step (1) can be a vertical equipment, and the molding process is: upper tube - fixed length - heating - cutting - heating - upper forming - heating - lower preforming - heating - trimming lower - lower material.

[0038] The vertical equipment manufacturer is Germany AMBEG Company, which is currently the most advanced equipment i...

Abstract

The invention relates to pharmaceutical glass, in particular to a borosilicate glass sleeve for a pen type syringe and a preparation method of the borosilicate glass sleeve. The borosilicate glass sleeve is characterized by comprising chemical composition of SiO2, Al2O3, B2O3, K2O, Na2O, CaO, MgO, BaO and Fe2O3. The preparation method includes steps: firstly, using a forming machine to forming the pharmaceutical neutral borosilicate glass sleeve; secondly, annealing the formed glass sleeve in an electric annealing furnace; thirdly, visually checking the glass sleeve, and fourthly, packaging and storing. The borosilicate glass sleeve and the preparation method have the advantages that the glass performance can reach the first-level waterproof requirement by means of the materials and the preparation method, content of silica, alumina and boron trioxide is high, and content of alkali metallic oxide is low, so that high chemical stability, thermal stability and mechanical strength or products can be guaranteed.

Description

technical field [0001] The invention relates to a medicinal glass, in particular to a borosilicate glass sleeve for a pen type injector and a preparation method thereof. Background technique [0002] For a long time, the injection products produced by Chinese pharmaceutical companies have been packaged in traditional packaging. The pen-type syringe is a new generation of injection packaging container that appeared in the international market in 2002. Its appearance better meets people's needs for easy use and safe medication. requirements, and will lead to epoch-making changes in the packaging of water injection and powder injection products and the way of clinical medication. [0003] There are two defects in traditional injection packaging: First, there are hidden dangers in the safety of patients' medication. Before the injection is used, when the operator breaks the ampoule, fine glass powder will be produced. These glass powders may be mixed with the medicine and cause...
