Abstract

A Φ40‑70mm medicinal neutral borosilicate glass tube and a manufacturing method thereof, belonging to the technical field of medicinal glass tube production, aiming at solving the problem of the existing Φ40‑70mm large-capacity tube containing liquid medicinal neutral borosilicate glass tubes There is a technical bottleneck in production. The weight ratio of raw materials used in it is 71-77.1 parts of silicon dioxide, 5.2-7.1 parts of aluminum oxide, 8.2-11.6 parts of diboron trioxide, 0.5-2.4 parts of calcium oxide, 0.5-7.4 parts of potassium oxide, sodium oxide 5.0 to 7.6 parts, 0.2 to 1.0 parts of lithium oxide, the production method includes raw material preparation, glass melting, glass tube forming, precision cutting round mouth, inspection and packaging of all-electric fusion velofara with a diameter of 40‑‑70mm Medicinal neutral borosilicate glass tube. The manufacturing method is advanced and feasible, and the quality of the manufactured glass tube is good, which is suitable for medicinal liquid preparation bottles such as 50ml-1000ml and above control injection bottles.

Description

technical field [0001] The invention belongs to the technical field of manufacturing glass tube products for medicinal purposes, and relates to a medicinal neutral borosilicate glass tube made of Vilofera and a manufacturing method thereof. Background technique [0002] With the development of the pharmaceutical industry and the continuous improvement of people's health, the technical requirements for pharmaceutical packaging products, especially pharmaceutical glass tube products, are also getting higher and higher. At present, the pharmaceutical industry uses low-grade molded sodium calcium or low borosilicate glass bottles for Φ40-70mm, that is, 40ml and above large-capacity controlled vials and infusion bottles. For strong alkali medicines (such as sodium bicarbonate), if the above-mentioned packaging is used, a large amount of flakes will be generated during the validity period of the medicine, which makes the medicine have a huge risk. In the known technology, the exi...
