In life, we often use all kinds of glass products, such as glass windows, glass cups, glass sliding doors and so on. Glass products are both aesthetically pleasing and practical, and they are able to make use of their crystal-clear appearance and make full use of their hard and durable physical properties. Some art glass will even make the glass have more patterns to enhance the decorative effect. In this article we will introduce how glass beer bottles are made and what the chemical composition of glass bottles is.
First, how is the glass beer bottle made?
The glass bottle production process mainly includes:
1 raw material pre-processing. The bulk material (quartz sand, soda ash, limestone, feldspar, etc.) is pulverized to dry the wet raw material, and the iron-containing raw material is subjected to iron removal treatment to ensure the quality of the glass.
2 batch preparation.
3 melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool kiln or a pool furnace to form a liquid glass which is uniform, free of bubbles and meets the molding requirements.
4 molding. The liquid glass is placed in a mold to form a glass product of a desired shape, such as a flat plate, various utensils, and the like.
5 heat treatment. Through the processes of annealing, quenching, etc., the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.
