Description

technical field [0001] The invention relates to a tempered glass production device and a production method thereof, in particular to an ultra-thin tempered glass production device and a production method thereof. Background technique [0002] At present, the methods of producing tempered glass mainly include physical tempering method and chemical tempering method. Among them, the physical tempering method refers to heating the glass to the softening temperature, eliminating internal stress through its own deformation, and then blowing high-pressure cold air to both sides of the glass. Tempered glass is obtained by rapidly and uniformly cooling to room temperature. Due to the small thermal conductivity of the glass, the two surfaces of the glass shrink and harden first, but the inside of the glass still has a relatively high temperature. As a result, the first hardened surface produces compressive stress, and then the hardened interior produces tensile stress, which makes or...
