In recent years, with the rapid improvement of modern technology, the old and traditional glass industry has been renewed, and various glass products with unique functions have appeared one after another. These glasses can not only play a traditional light transmission effect, but also play an irreplaceable role in some special occasions.
The main process of glass production process
The glass production process mainly includes:
①Pre-processing of raw materials. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of glass.
②Preparation of batch materials.
③ Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
④Forming. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc.
⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is cleaned or generated, and the structural state of the glass is changed
