Terms and definitions for pharmaceutical glass containers

 

Pharmaceutical glass containers

Glass container with good chemical stability and transparency, direct contact with drugs and stable storage of drugs.

 

Tubular glass containers

After the material is melted in the glass kiln to the glass liquid that meets the molding requirements, it is pulled into the glass tube used in the production of the tube bottle. In the production of the glass container, the glass tube is processed twice to make the glass container with a certain geometric shape. The pipe forming is the production process of the second forming.

 

Molded glass containers

After the mating material is fused to the glass liquid in line with the requirements of the molding in the glass kiln, the molding equipment is used to directly make the glass container with a certain shape with the help of a variety of different shapes of the mold is a one-time molding production process.

 

Inner surface duiability of glass containers

The ability of the inner surface of a glass container to withstand the physical and chemical effects of chemicals such as water, acid, and alkali, as well as environmental factors such as temperature and pressure during the duration of its packaging contents.

 

 

Delamination

Due to the interaction between the contents and the glass container, the inner surface of the glass container falls off, resulting in snowflake (or flake) flakes in the contents, whose sizes can range from 50μm to 200μm.

 

Light protection

The ability of a glass container to block the passage of light at specific wavelengths in order to protect the substance from light.

 

Internal surface treatment

A process used to improve and improve certain properties of the inner surface of glass containers.
Note: such as neutralization treatment and silication treatment.

 

Outer surface treatment

In order to improve the strength of the medicine bottle and prevent scratch, the outer surface of the glass container was treated.
Note: such as hot end coating and cold end coating on the outer surface of glass.

 

Neutralizing treatment

It is used to reduce the release of alkali metal ions on the inner surface of glass.

 

Siliconizing

Used to improve the duty - raising performance or lubrication performance of the inner surface of glass container.
Note: for example, the inner surface of medicinal glass container is treated with silicone oil (emulsion) and solidified.

 

SiO2 coating

Used to reduce the migration of glass components. For example, pulsed ion chemical deposition (PICVD) is used to make the inner surface of the glass packaging container react with the silicon-containing gas (hexamethyldisiloxane HMDS) by plasma, so as to form a compact and uniform silicon dioxide coating by covalent bonding.

 

Glass chemical strengthening

Glass container immersed in some of the salts of the melt in the heating, with larger ionic radius of alkali metal ions (such as potassium ions) exchange small radius in the glass of alkali metal ions such as sodium ions), due to the large leopard cat account of small holes in the glass network structure, the squeezing effect, make glass surface produce permanent pressure, to improve the performance of the glass surface.

 

The cold end coating

In order to improve the impact strength, friction resistance and scratch resistance of the glass container, the polymer is sprayed on the outer second surface of the glass container with compressed air when the glass container is annealed to low temperature to form a very thin coating.

 

The hot end coating

In order to improve the compressive strength of the glass container, the coating material was sprayed on the outer surface of the glass container by chemical meteorological deposition at high temperature after forming.

 

Shape

Reflects the shape and construction of the product manufactured.
