Formula and preparation method of alkali-resistant medium borosilicate medicinal glass

Abstract

The invention discloses a preparation method of alkali-resistant medium borosilicate medicinal glass, which comprises the following steps: firstly, taking corresponding parts by mass of raw materials according to the proportion for later use; secondly, fully mixing the raw materials, adding the raw materials into a smelting furnace, completely melting the raw materials, and fully conducting mixing again; then, adopting a blow-press molding process, when the temperature of the molten material reaches 1100-1120 DEG C, conveying the molten material into a corresponding mold, and completing mold pressing; then, annealing the product in the mold, and taking out the product after cooling is completed; and finally, conducting inspecting and packaging, warehousing qualified products, and recycling unqualified products. According to the invention, the difficulty of producing glass bottles for containing a sodium bicarbonate medicine can be reduced, the technical problems of difficult melting, difficult clarification and difficult forming in the glass bottle manufacturing process are solved, the forming rate of glass bottle production is greatly improved, and the glass bottle made of the medium borosilicate glass can be widely used.

Description

technical field [0001] The invention relates to the field of medicine bottles, in particular to the formula of alkali-resistant medium borosilicate medical glass and its preparation method. Background technique [0002] At present, when used to store, place and hold alkaline drugs, especially sodium bicarbonate drugs, most of them are placed in glass tubes, and when glass tubes are placed, specific brackets are required, which is inconvenient for the drug to be taken, and the pressure-bearing capacity lower. The use of medium borosilicate glass to make glass bottles will solve the above problems well, but the production difficulty of making glass bottles is much greater than that of glass tube molding, because medium borosilicate glass is difficult to melt, difficult to clarify, and difficult to shape. The lower the molding temperature, the more difficult the corresponding production is, making it difficult for glass bottles made of medium borosilicate glass to be widely us...
