Glass jar is a kind of chemical utensils commonly used in food packaging, gift packaging, and medicinal packaging.
The glass jar production process mainly includes pre-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 the glass. The batch material is prepared and melted. The glass batch material is heated at a high temperature of 1550~1600 degrees in a pool kiln or a pool furnace to form a uniform, bubble-free liquid glass that meets the forming requirements. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc. for heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
Glass jars can prevent deformation, leakage, and deterioration of product components caused by chemical reactions.
