Basic knowledge of glass production process
Glass as a packaging material mainly used for food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, use very extensive.
But glass also has its disadvantages, such as the weight of large, high transport cost of storage, the impact of intolerance and so on. glass
The main raw material of glass bottles is natural ore, quartz, soda, limestone.
Glass bottle with a high degree of transparency and resistance to corrosion, most chemicals are in contact with the material properties change does not occur.
Its manufacturing process is simple, freely changing shape, hardness, heat, clean, easy to clean, and can be repeated use features.
We must first determine the design and manufacture of molds, glass raw materials quartz sand as the main raw material, together with other materials melt into liquid at high temperatures, oil bottles and then injected into a mold, cooled, cut, tempered glass is formed.
Glass bottles are generally rigid signs, signs are made from the mold shape.
Glass molding according to the production methods can be divided into artificial blowing, blowing and extrusion machinery three.
Glass components can be divided according to the following categories:
First, soda bottles Second, Third, lead glass, borosilicate glass bottles.
