Glass bottle surface treatment technology to improve stability: physical strengthening (tempering), also known as air cooling strengthening, is designed to improve the mechanical strength and thermal stability of glass bottles. Physical strengthening processing methods are as follows: Bottles from the bottle blowing machine after demoulding, immediately sent troops, type of toughened furnace heat evenly to close to softening temperature of the glass (but cannot achieve softening temperature), and then turn to toughened room, with a perforated nozzle wind gate to bottles of inside and outside the walls of the cold air jet, rapid cooling bottles, or sudden cooling bottles with liquid as cooling medium,The compressive stress layer is formed on the surface of the product due to sudden contraction, and the cooling inside the product is a tensile stress layer due to lag behind the surface. When these two kinds of stress distribution is reasonable, the internal pressure strength of the glass can be improved exponentially. The air pressure of the jet bottle body is generally 15 ~ 21kPa, and the air pressure of the bottom of the jet bottle is generally 6 ~ 7kPa.
