In life we often use a variety of glass products, such as glass windows, glass cups, glass sliding doors, etc.. Glass products are both beautiful and practical. Glass bottles raw materials to quartz sand as the main raw material, plus other auxiliary materials dissolved at high temperature into a liquid state, and then the essential oil bottle into the mold, cooling, cutting, tempering, it forms a glass bottle. Glass bottles generally have a rigid logo, the logo is also made from the shape of the mold. Glass bottle forming according to the production method can be divided into three kinds of manual blowing, mechanical blowing and extrusion molding. Here is a look at the process of glass bottle production and production.
The production process of glass bottles.
1. Raw material pre-processing. The lumpy raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed, so that the wet raw materials are dry, and the iron-containing raw materials are de-ironed to ensure the quality of glass.
2. Compound preparation.
3. Melting. Glass with materials in the pool kiln or pool furnace for high temperature (1550 ~ 1600 degrees) heating, so that the formation of uniform, bubble-free, and meet the requirements of the liquid glass molding.
4. Forming. Liquid glass into the mold into the required shape of glass products, generally first molding the bottle embryo, and then the embryo will be molded into the bottle body.
5. Heat treatment. Through annealing, quenching and other processes to clean up or produce internal glass stress, phasing or crystallization, and change the structural state of the glass.
