Problems solved by technology

[0003] The chemical stability of medicinal glass refers to the ability of glass to resist the erosion and damage of gas or water, acid, alkali, other chemical reagents and drug solutions. As a pharmaceutical packaging material, the corresponding medicinal glass requires high acid resistance , Alkali resistance, low borosilicate glass and soda lime glass have many problems, such as high amount of alkali metal precipitation, some may also appear to fall off

Abstract

The invention relates to a formula of a pharmaceutical neutral borosilicate glass tube. The pharmaceutical neutral borosilicate glass tube comprises components with the following parts by weight: 260 to 280 parts of quartz sand, 14 to 18 parts of lepidolite, 25 to 35 parts of aluminum hydroxide, 3 to 5 parts of fluorite, 80 to 100 parts of borax pentahydrate, 4.5 to 6 parts of sodium carbonate, 9 to 12 parts of sodium nitrate, 3 to 4.5 parts of potassium carbonate, 4.5 to 5.5 parts of barium carbonate, 4 to 5 parts of a compound glass clarifying agent, and 120 to 140 parts of cullet. The invention has the benefits that the product has higher chemical stability, heat stability and water resistance, so that the mechanical strength of the product is remarkably improved; through a production method of the neutral borosilicate glass tube, the product qualification rate reaches 90 percent, energy is saved, and pollution, waste gases and volatiles are eliminated.

Description

technical field [0001] The invention relates to the technical field of production of glass medical tubes, in particular to a formula and a production method of neutral borosilicate glass medical tubes. Background technique [0002] With the rapid development of my country's pharmaceutical industry, the quality requirements for pharmaceutical packaging materials are getting higher and higher. The developed countries in the world have already generally adopted neutral glass control bottles with an expansion coefficient of 5.0. Glass of choice for packaging. The so-called neutral glass means that the long-term contact between the glass container and the liquid medicine will not cause a change in pH value, and there will be no sedimentation or glass shavings falling off. At present, more and more pharmaceutical companies in my country have begun to use international neutral glass. Glass. [0003] The chemical stability of medicinal glass refers to the ability of glass to resist ...
