Production method of glass vials
【Technical field】
The present invention relates to a method for producing glass vials, in particular pharmaceutical vials or ampoules, and glass vials produced therefrom.
【Background technique】
Medical glass bottles (also known as "vials") consist of neutral glass, which can be classified as hydrolyzed grade 1 glass, and standardized test ISO 719 (DIN 12111) is also used. Grass, especially borosilicate glass, such as Duran ® Or fiohx ® (both registered trademarks of mainzschott company) is neutral glass.
[0003] in addition, vials or ampoules must have the lowest possible alkali metal emission, which is measured according to standardized test ISO 4802. The glass surface caused by evaporation and deposition of glass components must be avoided, especially in the thermoforming process. In other words, in the worst case, this stratification will enter the contents of the vial and destroy the contents.

1. In terms of manufacturing process, medicinal glass bottles are generally divided into two categories: molded bottles and tube bottles. Molded bottles are divided into large-mouth bottles (bottle diameter above 30MM) and small-mouth bottles. The former is used to hold powder, block and paste items, and the latter is used to hold liquid.
2. According to the form of the bottle mouth, it is divided into cork bottle mouth, screw bottle mouth, crown cap bottle mouth, rolling bottle mouth and frosted bottle mouth, etc. According to the usage, it is divided into "single-use bottles" which are discarded after one use and "recycling bottles" which are used for multiple turnovers.
3. According to the contents, it can be divided into acid bottles, medicine bottles, reagent bottles, infusion bottles, preparation bottles, etc.

4. Medicinal glass bottles can be roughly divided into the following categories according to the different uses of medicines: packaging of infusion solutions, packaging of oral liquids, packaging of tablets and capsules, and packaging of powder injections. Infusion solution packaging: domestic large infusion packaging is mainly glass infusion bottles

1. Rotating speed: during the expansion of centrifugal pipe, the rotating speed and diameter determine the centrifugal force. When the diameter is constant, the higher the speed is, the greater the centrifugal force is. Under the action of centrifugal force, the larger the diameter is, the slower the speed is. Therefore, during pipe expansion, the expansion rate shall be used as the basis of glass pipe diameter
2. Determine the wall thickness and the corresponding temperature. Heating and softening pressure in the process of pipeline expansion, the sizing device to control the diameter mainly depends on a set of synchronously rotating glass tube, which needs a wider speed range.

principle

The aim is to eliminate permanent stresses and structural imbalances in glass products. Glass is a poor conductor of heat. After the product forming, the surface layer and the inner layer in the cooling process will produce temperature difference. When the surface layer solidifies and the inner layer is sticky, there is a temperature difference but no stress relaxation. This temperature difference occurs when the surface layer is cooled to room temperature. , the inner layer continues to cool and shrink, resulting in tensile stress hindered by the surface layer, while the surface layer produces permanent compressive stress. The size and distribution of the permanent stress caused by the thermal process are not uniform in each part of the product, so it will affect the strength of glass products, and even self-breakage due to stress concentration. Annealing removes harmful strains in the glass and prevents new stresses from forming.
