Talking about the annealing technology of glass bottle glass jar

After the glass bottle is formed, it is continuously conveyed to the annealing kiln by the bottle conveyor through a bottle pusher for annealing. The current annealing kiln has forced convection, radiant heating, and heat flow in circulation. Control of glass temperature, increase in annealing temperature, reduction in fuel, energy consumption, and reduction in return time are all improved.

Characteristics and types of glass bottles: Glass bottles are the main packaging containers for food, medicine and chemical industries. They have good chemical stability; easy to seal, good air tightness, transparent, can observe the contents from the outside; good storage performance; smooth surface, easy to disinfect and sterilize; beautiful in appearance, rich in decoration; The strength can withstand the pressure inside the bottle and the external force during transportation; the raw materials are widely distributed and the price is low. The disadvantage is that the quality is large (the mass to capacity ratio is large), the brittleness is large, and it is brittle. However, in recent years, with the use of thin-walled lightweight and physical-chemical tempering new technologies, these shortcomings have been significantly improved, so glass bottles can compete with plastic, iron, and iron cans, the output is increasing year by year.

There are a wide variety of glass jars, from small bottles of 1ML to large bottles of dozens of liters, from round, square, to shaped and bottled handles, from clear, amber, green, blue and black shaded bottles. Opaque opaque glass bottles, etc., are too numerous to mention. In terms of the manufacturing process, glass bottles are generally divided into two types: molded bottles (using model bottles) and control bottles (with glass bottles). Molded bottles are divided into two types: large-mouth bottles (both mouth diameters above 30MM) and small-mouth bottles. The former is used to hold powder, block and paste items, and the latter is used to hold liquids. According to the bottle mouth form, it is divided into cork bottle mouth, threaded bottle mouth, crown cap bottle mouth, rolling bottle mouth frosted bottle mouth and so on. According to the usage, it is divided into "one-time bottle" that is used once and used, and "recycled bottle" that is used for multiple turns. According to the classification of the contents, it can be divided into wine bottles, beverage bottles, oil bottles, canned bottles, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetic bottles, etc.
