Medium borosilicate glass injection agent bottle for small-dose injection

Abstract

The invention relates to a medium borosilicate glass injection agent bottle for small-dose injection, and belongs to the field of medicinal glass. The medium borosilicate glass injection agent bottleis prepared from the following raw materials in parts by mass: 200 to 250 parts of quartz sand, 10 to 13 parts of aluminum oxide, 1.0 to 2.5 parts of barium carbonate, 30 to 35 parts of boric acid, 35to 40 parts of borax, 15 to 18 parts of sodium carbonate, 5 to 7 parts of sodium nitrate and 1.5 to 2.2 parts of cerium oxide. According to the invention, by reasonably matching SiO2, Al2O3, B2O3, Na2O and other components in the formula, the performances of glass can meet the neutral requirements; the gas rate is low, and a cold top melting mode is adopted, so that the volatilization of the rawmaterials is reduced, and the pollution to the atmosphere is reduced; and cerium oxide is used as a clarifying agent to replace white arsenic, so that the residue of toxic components in the glass areavoided, and the use safety is improved.

Description

technical field [0001] The invention relates to a medium-borosilicate glass injection bottle for small-dose injection, which belongs to the field of medicinal glass. Background technique [0002] At present, small doses of medicines are often used in the injection process, so small doses of injection medicine bottles are inevitable. With the development of Western medicine, there are more and more such small doses of medicine injection bottles. However, biological In small-capacity injections for preparations, the main substance content is medium borosilicate glass bottles, but the current formula is unreasonable, resulting in the use of medium-borosilicate glass tube heat-processed control bottles. The glass surface of the control bottles is damaged by the thermal processing process. And cause the volatilization of part of the glass components, resulting in the increase of migration caused by containing medicines. [0003] Borosilicate glass infusion bottles have high chem...
