Physical reinforcement (
Toughened) Also called the air-filled strengthening, the purpose is to improve the mechanical strength and thermal stability of glass bottles. Physical reinforcement processing method is as follows: bottles after demoulding by bottle blowing machine, immediately sent troops, type of toughened furnace heat evenly to close to the glass softening temperature ( But it can't reach 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 cooling medium for bottles with a liquid and the surface because of the sudden contraction of the products formed by compressive stress layer, internal cooling products because of the lag of tensile stress in surface layer, when these two stress distribution is reasonable, glass resistance to internal pressure strength can be doubled. The air pressure spray bottle, as a general rule, be 15 ~ 21 kpa, the air pressure spray bottle, as a general rule, be 6 ~ 7 kpa.
