Glass has excellent properties and can be used in a variety of applications. In interior decoration, stained glass and hot-melt glass can be used, with various styles. Tempered glass, laminated glass and other safety glasses are suitable for occasions where personal safety is required; frosted glass and dimming may be used when brightness and privacy protection are needed. Glass, convenient and durable. What is the production process of glass packaging containers?
First, design and determine the mold. The glass raw material is quartz sand as the main raw material, and other auxiliary materials are dissolved at a high temperature to form a liquid. Then it is injected into the mold, cooled, cut and tempered to form a glass bottle. Glass bottles usually have a rigid logo, and the logo is also made of the shape of a mold. Glass bottle molding can be divided into three types: manual blowing, mechanical blowing and extrusion molding. Glass bottles can be divided into the following types according to their composition: one is soda glass, the other is lead glass, and the third is borosilicate glass.
The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone, etc. Glass bottles are highly transparent and resistant to corrosion, and will not change material properties when exposed to most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, 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 they are widely used. However, glass bottles also have their disadvantages, such as heavy weight, high transportation and storage costs, and resistance to impact.
