All-electric viilo drawn medicinal glass tube and method for making the same

Abstract

The invention provides a medicinal glass tube which is made through a whole fused villo method and a preparation method, belonging to the medicine packing technical field and aiming at solving problems of weak acid-resistance and alkaline-resistance, low mechanical-resistance strength and easy break of a present medicinal glass tube. Used raw materials in weight portion include 71.0-77.1 portions of silicon dioxide (SiO2), 5.2-7.1 potions of aluminium sesquioxide (Al2O3), 8.2-11.6 potions of boron trioxide (B2O3), 0.2-2.6 potions of barium oxide (BaO), 0.2-2.4 portions of calcium oxide (CaO), 0.2-1.0 portions of lithium oxide (LiO), 0.5-7.4 portions of potassium oxide (K2O) and 5.1-7.6 portions of sodium oxide (Na2O). The manufacturing method consists of procedures of the raw materials preparation, the fused melting plastics heating, the villo stretching forming, the precise cutting, the mouth rounding and the packing. The invention has the advantages of optimal expansion coefficient and high mechanical-resistance strength and is applied to the manufacturing of medicinal glass vessels for containing medicine liquids and medicines, the chemical pipes, etc.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical packaging, a medicinal glass tube and a manufacturing method thereof. Background technique [0002] With the development of the pharmaceutical industry and the rapid advancement of science and technology, the corresponding technical requirements for the packaging of pharmaceutical products, especially glass bottles for liquid medicines, are also getting higher and higher. In the known technology, the medicinal glass tubes used in the existing glass bottles for liquid medicine packaging are mainly the method of Danner method fuel traditional flame heating, the temperature error of the glass liquid measured by the temperature measuring instrument is large, and it is easily corroded by the high temperature glass liquid , to bring in impurities, limited by its ingredients and process methods, the expansion coefficient of the produced glass tubes for medicine is large, and the glass bottles made...
