The production technology of glass bottle mainly includes:
1.raw material preprocessing. The bulk material, such as quartz sand, soda ash, limestone and feldspar, is comminuted to dry the wet material and remove iron from iron containing raw materials to ensure the quality of glass.
2. Preparation of mixture.
3.melting. Glass mixture is heated in a tank or pool furnace at high temperature (1550~1600 degrees) to form a homogeneous, non bubble and liquid glass that meets the requirements of the molding.
4.forming. The liquid glass is placed in a mold to make the desired shape of glass, such as a flat plate, a variety of utensils, etc. Heat treatment. By annealing, quenching and other processes, the stress, phase separation or crystallization in the glass, and the structural state of the glass are eliminated or produced.
