Glass bottle is a traditional liquor beverage packaging container in China, and glass is also a kind of packaging material with a long history.In the case of many kinds of packaging materials flooding into the market, glass container still occupies an important position in beverage packaging.And it has other packaging materials can not be replaced by the packaging characteristics inseparable.Now take you to understand how to make glass bottles。
1.Technological Process
The liquor glass bottle production process mainly includes:1) The raw material is pre-processed to crush the block raw materials (quartz sand, soda soda, limestone, feldspar, etc.) to dry the wet raw materials, and remove the iron containing raw materials to ensure the quality of glass.2) Preparation compound.3) Founding.The glass compound is heated at high temperature (1550~1600 degrees) in the tank kiln or furnace,make it form uniform no bubble, and meet the forming requirements of liquid glass.4)Shape up.Put the liquid glass into the mold to make the desired shape of glass products, such as plates, utensils, etc.5)Tempering.Through annealing and quenching and other processes, eliminate or produce the stress phase separation or crystallization inside the glass, and change the structural state of glass.
2. Work Flow
The first step is to design, determine and manufacture the mold,The glass raw material is quartz sand as the main raw material, and other auxiliary materials are dissolved into liquid at high temperature, and then injected into the mold, cooling the cut and tempering, and the glass bottle is formed.Glass bottles generally have rigid signs, signs are also made of mold shape glass bottle molding according to the production method can be divided into manual blowing mechanical blowing and extrusion molding three.According to the composition of glass bottles can be divided into the following kinds: one is sodium glass, two is lead glass, three is borosilicate glass.
The main raw materials of glass bottles are natural ores, quartz stone, caustic soda, limestone and so on.Glass bottles are highly transparent and resistant to corrosion. Contact with most chemicals will not change the material properties.Its manufacturing process is simple, the shape is free and changeable, the hardness is large, the heat resistance is clean and easy to clean, and it can be used repeatedly.But glass bottles also have its disadvantages, such as large weight, high transport storage costs, impact resistance and so on.
