Four steps in glass bottle production
Four steps in glass bottle production
Glass bottles come in all kinds from large bottles to small bottles and are widely used in food, medicine, beverage and other packaging containers. Glass bottle manufacturers point out that it is a very safe and environmentally friendly packaging container that can be recycled. Glass production process includes: batching, melting, forming, annealing and other processes.
The glass bottle ingredients, in accordance with the design of the material side list, all kinds of raw materials will be weighed and mixed evenly in a mixer. The main raw materials of glass are: quartz sand, limestone, feldspar, soda, boric acid, etc.
Glass bottle melting, the raw material will be heated at high temperature, the formation of uniform bubble-free glass liquid. This is a very complex physical and chemical reaction process. The melting of glass takes place in a furnace.
Glass bottles are formed by changing molten glass into solid products with fixed shapes. Forming must take place within a certain temperature range. It is a cooling process in which glass changes first from a viscous liquid to a plastic state and then to a brittle solid.
The annealing of the glass bottle, the glass in the forming process has undergone a drastic change in temperature and shape, this change in the glass left a thermal stress. This thermal stress will reduce the strength and thermal stability of glass products. Glass bottle manufacturers point out that if the glass is cooled directly, it is likely to break spontaneously during cooling or later storage, transportation and use (commonly known as cold burst of glass).
