Abstract

The invention relates to a Phi 40-70mm medicinal neutral borosilicate glass tube and a manufacturing method thereof, belonging to the technical field of manufacturing of medicinal glass tubes and aims to solve the problem that the existing Phi 40-70mm medicinal neutral borosilicate glass tube for high-capacity tube-made liquor has the technical bottle neck in manufacturing. The borosilicate glass tube is prepared from the following raw materials in parts by weight: 71-77.1 parts of silicon dioxide, 5.2-7.1 parts of aluminum oxide, 8.2-11.6 parts of boron trioxide, 0.5-2.4 parts of calcium oxide, 0.5-7.4 parts of potassium oxide, 5.0-7.6 parts of sodium oxide and 0.1-1.0 part of lithium oxide. The manufacturing method comprises the following steps: preparing the raw materials, melting the glass, forming the glass tube, finely cutting the pylome, inspecting and packaging to obtain the Phi 40-70mm medicinal neutral borosilicate glass tube prepared by an all-electrofusion Vello process. The manufacturing method is advanced and feasible; the prepared glass tube has good quality; and the manufacturing method is suitable for 50-100ml and above tube-made injection bottles and other medicinal liquor 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...
