The medicine package refers to a packaging material and a container which are in direct contact with tablets, and the glass material is widely used in the fields of biological products, injection needles and the like due to the advantages of high temperature resistance, easy sterilization, recoverability and the like. The glass materials involved in the prodrug packaging material can be divided into borosilicate glass and soda-lime glass according to different components, and neutral borosilicate glass gradually replaces other types of packaging materials due to the advantages of small expansion coefficient, strong extreme cold and heat resistance, high mechanical strength, strong impact resistance, good chemical stability, high acid and alkali resistance level and the like. Meanwhile, neutral borosilicate glass also has the problems of easy delamination of molten glass, difficult homogenization and clarification and the like in the manufacturing process, so in order to ensure the full melting of the molten glass and the stability of the melting quality, the molten glass in a kiln is generally homogenized and clarified by an auxiliary bubbling system while being heated by using a dual heating scheme of an oxy-fuel combustion system and an electric boosting system.

However, the glass furnace can cause heavy metal impurity glass liquid to be formed and deteriorated at the bottom of the tank in the using process, and the deteriorated glass liquid can cause the blocking phenomenon of a bubbling pipe in a bubbling system, so that the homogenizing and clarifying effects of the glass liquid in the furnace are weakened.
