Abstract

The invention relates to a method for preparing a medical brown bottle by using broken glass, and belongs to the technical field of production technology of glass. The method is characterized in that the brown bottle consists of the following oxide chemical components by weight percentage: 70 to 73 percent of SiO2, 1.8 to 2.2 percent of Al2O3, 0.2 to 0.4 percent of Fe2O3, 7.8 to 8.1 percent of CaO, 2.0 to 2.5 percent of MgO, 14 to 15 percent of R2O, and 0.25 to 0.33 percent of BaO, wherein R is Na or K; and the raw materials contain the broken glass accounting for 10 to 20 percent of the total weight of the raw materials. Through limiting granularity and mixing evenness of the broken glass, the method solves the problem of homogenization of the raw materials, and improves quality of the glass to facilitate medicine packing.

Description

technical field [0001] The invention belongs to the technical field of glass production technology, and in particular relates to a method for producing medicinal brown bottles by using broken glass. Background technique [0002] How to effectively reuse the large amount of waste cullet produced by the glass industry is one of the urgent issues to be solved by glass workers in China and even around the world. In the prior art, the recycling of waste (or waste) glass is mainly used for flat glass, crock glass, etc., which require relatively low quality indicators such as glass impurities. For glass varieties with high quality requirements, such as float glass, waste glass is generally not added as raw materials. "Recycling and Utilization of Waste Glass" (Jiang Wenjiu "Shanghai Building Materials" No. 3, 2003) discloses the application of the prior art to waste cullet, and its disclosed content is quoted here. [0003] It is generally believed that cullet can accelerate melt...
