Our glass jars can be mainly divided into glass food jars and glass cream jars. Glass jar is a kind of chemical vessel commonly used in food packaging, cosmetic packaging, and medicinal packaging. Glass jar production process: The glass jar production process mainly includes raw material preprocessing. Crush the massive raw materials (quartz sand, soda ash, limestone, long-lasting stone, etc.), dry the wet raw materials, and remove iron from the iron-containing raw materials to identify the moonship winding path. Ensure glass quality. Batch preparation and melting. The glass batch materials are heated in a pool kiln or pool furnace at a high temperature of 1550~360°C to 1600°C to form a liquid glass that is uniform, bubble-free and meets the molding requirements. The liquid glass is put 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 stress, phase separation or crystallization inside the glass is eliminated or caused, and the structural state of the glass is changed.
