Production process editing
It mainly includes:
(1) Raw materials pre-processing.The lumpy raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed to dry the wet raw materials, and the iron-containing raw materials are removed to ensure the quality of glass.
(2) Preparation of compound materials.
(3) melted.The glass mixture is heated at a high temperature (1550~1600 degrees) in a tank kiln or crucible kiln to form uniform, bubble-free liquid glass that meets the molding requirements.
(4) shape.Process liquid glass into desired shapes, such as flat plates, various utensils, etc.
Heat treatment.Through annealing, quenching and other processes, the stress, phase separation or crystallization in glass are eliminated or produced, and the structural state of glass is changed.
