Glass bottle production process mainly includes: ① raw materials processing. Crushing raw materials (quartz sand, soda ash, limestone, feldspar, etc.), so that drying raw materials dry, iron containing raw materials for iron removal to ensure the quality of glass. Preparation of ② mixture. ③ melting System. The glass mixture is heated at high temperature (1550~1600度) in a pool kiln or pool furnace to form a homogeneous, bubble-free liquid glass that conforms to the molding requirements. ④ molding. Put the liquid glass into the mold to make the required shape of glass products, such as flat plate, various utensils. ⑤ heat treatment.
Through annealing, quenching and other processes, the elimination or production of glass inside the stress, phase or crystallization, and change the structure of the glass state.
