Abstract

The invention relates to a formula and a preparation method for first-level waterproof glass molding injection bottle glass, and belongs to the field of pharmaceutical glass infusion bottles. The first-level waterproof glass molding injection bottle glass comprises the following raw materials: by mass, 76-79% of SiO2, 1.8-2.6% of Al2O3, 0.3-0.4% of MO, 12.6-13.4% of B2O3, 7.3-7.8% of R2O and 0.02-0.03% of Fe2O3. The melting quality is ensured, and the gas ratio is relatively low. Cold heading melting is adopted, so that the volatilization of the raw materials is reduced, and the pollution of the air is reduced. Cerium oxide is used for replacing white arsenic as a fining agent, so that the remaining of toxic components in the glass is avoided, and safety of use is promoted.

Description

technical field [0001] The invention relates to a formula and a preparation method of first-class water-resistant glass molded injection bottle glass, belonging to the field of medicinal glass infusion bottles. Background technique [0002] The first-class water-resistant glass infusion bottle has a higher chemical stability requirement as a first-class water-resistant glass because it is in direct contact with the drug. The prescription composition of glass is the intrinsic determinant of its chemical stability. The international standard ISO12775-1997 "Classification of normal mass-produced glass by composition and its test method" clearly divides medicinal glass into three types: [0003] a. Neutral glass [0004] The linear thermal expansion coefficient of this glass is: [0005] α=(4~5)×10 -6 K -1 (20~300℃) [0006] Its chemical composition is: [0007] SiO 2 ≈75%B 2 o 3 8~12%R 2 O4~8%RO<5%Al 2 o 3 2~7% [0008] b. Soda lime silicate glass [0009] The...
