Problems solved by technology

[0002] With the development of society, the standard of medical product packaging is gradually increasing, and the use of brown glass tubes is favored. In the process of visible light and ultraviolet sensitive drug containers, the main raw material is low borosilicate glass tube for medicine, but the low borosilicate glass tube has problems such as high light transmittance and low ultraviolet blocking rate, so it cannot meet some requirements for visible light and ultraviolet light. Packaging requirements for sensitive drugs; in addition, because the boron content of the low borosilicate glass tube is between 6-8%, it does not meet the standard requirements of pharmaceutical neutral borosilicate glass, and there are chemical stability, mechanical strength and impact resistance Problems such as poor quality and easy peeling off, which affect the quality of medicinal glass bottle products
Therefore, brown glass tubes are reused mainly because of their good chemical stability, mechanical strength and impact resistance, and they have the characteristics of low visible light transmittance and high ultraviolet cut-off rate. Using the raw materials of glass containers can effectively avoid the defects of existing low borosilicate glass tubes, but because the general brown glass is neutral borosilicate brown medicinal glass, its B 2 o 3 The content is high, the viscosity of the glass liquid is high, and the heat permeability is poor, so when the flame furnace is produced, the B 2 o 3 The amount of volatilization is large, usually 8%-12%, resulting in large changes in glass composition, reduced physical and chemical properties of the product, increased raw material costs, and polluted the atmospheric environment
In addition, when preparing medical glass, flame furnaces are often used for production. Due to the poor heat transmission performance of colored glass, there is a large temperature difference between the upper and lower sides of the glass liquid, and it is difficult to discharge the bubbles in the glass liquid, resulting in a large amount of air bubbles in the product. The bubble line seriously affects the quality of the product
