in fact, this is just a way to reduce operating costs in the beer industry! The main reason is that the profits of the beer industry are gradually becoming transparent, and the waste recycling center collects and transfers them to the brewery at a low price or even without spending money. It is their ultimate practice to recycle them at a lower price, but it is generally difficult to see the true face of this situation, which greatly reduces the actual use cost of waste wine bottles. For the brewery, this is to create the purpose of maximizing income! Supplement on the material of glass bottle and melting temperature: the production technology of glass bottle mainly includes: ① pre-processing of raw materials. Bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed, wet raw materials are dried, and iron-containing raw materials are removed to ensure glass quality. (2) batch preparation. (3) melting. The glass batch is heated at high temperature (1,55 ~ 1,6 degrees) in a tank furnace or a tank furnace to form uniform, bubble-free liquid glass that meets the molding requirements. ④ molding. Liquid glass is put into a mold to make glass products with required shapes, such as flat plates and various utensils. ⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of glass are eliminated or produced, and the structural state of glass is changed. Production process of glass bottles: firstly, the mold should be designed and manufactured. Quartz sand is the main raw material of glass, and other auxiliary materials are melted into liquid at high temperature, then injected into the mold, cooled, cut and tempered to form glass bottles. Glass bottles generally have rigid signs, and the signs are also made of mold shapes. The molding of glass bottles can be divided into three types according to the manufacturing methods: manual blowing, mechanical blowing and extrusion molding. Glass bottles can be divided into the following types according to their components: first, sodium glass, second, lead glass and third, borosilicate glass. The main raw materials of glass bottles are natural ore, quartz stone, caustic soda and limestone. Glass bottles are highly transparent and corrosion-resistant, and the material properties will not change when they come into contact with most chemicals. Its manufacturing process is simple, its shape is free and changeable, its hardness is high, it is heat-resistant, clean and easy to clean, and it can be used repeatedly. As a packaging material, glass bottles are mainly used in food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc., and are widely used. But the glass bottle also has its disadvantages, such as heavy weight, high transportation and storage cost, and no impact resistance. Characteristics and types of glass bottles: Glass bottles are the main packaging containers in food, medicine and chemical industries. They have good chemical stability; Easy to seal, good air tightness and transparency, and the situation of the contents can be observed from the outside; Good storage performance; Smooth surface, convenient for disinfection and sterilization; Beautiful shape and colorful decoration; It has certain mechanical strength and can withstand the pressure in the bottle and the external force during transportation; Wide distribution of raw materials, low price and so on. Its disadvantages are large mass (large ratio of mass to capacity), brittleness and fragility. However, in recent years, these shortcomings have been significantly improved by adopting the new technology of thin-walled lightweight and physical and chemical tempering, so the output of glass bottles can increase year by year under the fierce competition with plastics, tin cans and tin cans. There are many kinds of glass bottles, from small bottles with a capacity of 1ML to large bottles with a capacity of more than 1 liters, from round and square bottles to special-shaped and handle bottles, from colorless and transparent amber, green, blue and black shading bottles and opaque opacified glass bottles, and so on. As far as manufacturing technology is concerned, glass bottles are generally divided into two categories: molded bottles (bottles made with models) and controlled bottles (bottles made with glass tubes). Molded bottles can be divided into two types: large-mouth bottles (the diameter of the bottle mouth is above 3MM) and small-mouth bottles. The former is used to hold powder, block and paste articles, while the latter is used to hold liquids. According to the bottle mouth form, it is divided into cork bottle mouth, threaded bottle mouth, crown bottle mouth, rolled bottle mouth frosted bottle mouth and so on. According to the use situation, it can be divided into "one-time bottles" that are used once and discarded, and "recycling bottles" that are used repeatedly. 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 bottle, infusion bottles, cosmetic bottles, etc.
