Abstract

The invention belongs to the technical field of glass manufacturing methods, and particularly relates to a sheet glass full-toughening method and fully toughened sheet glass. The sheet glass full-toughening method is suitable for manufacturing glass with the thickness of 2 mm-3 mm, and comprises the following steps: S10) providing glass; S20) placing the glass into a toughening furnace for heating, and setting the maximum heating temperature in the toughening furnace to be in the range of 700 DEG C-730 DEG C; S30) taking out the glass from the toughening furnace, then carrying out wind pressure quenching on the glass, and setting the wind pressure of the wind pressure quenching to be in the range of 20000 Pa-27000 Pa to obtain the fully toughened sheet glass. According to the sheet glass full-toughening method, on the basis of ensuring that the glass has a good appearance, the problem of half-toughening of the glass can be avoided, so that full-toughening of the glass with the thickness of 2 mm-3 mm is realized, after the glass with the thickness of 2 mm-3 mm is fully toughened, the stresses are respectively uniform, the strength is high, the performance of the glass with the thickness of 2 mm-3 mm is effectively improved, and the use demands of customers can be met.

Description

Technical field [0001] The invention belongs to the technical field of glass manufacturing methods, and in particular relates to a method for fully tempering thin plate glass and fully tempered thin plate glass. Background technique [0002] After the glass is cut to the corresponding size, the glass is then placed in the tempering furnace for heating. After the heating is completed, rapid and uniform cooling is performed to obtain tempered glass; after tempering, uniform compressive stress is formed on the surface of the glass, and tensile stress is formed inside. The performance of the glass is greatly improved, the tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter; however, in the existing glass tempering process, it cannot be achieved for glass with a thickness of 2mm to 3mm. Fully tempered glass. Summary of the invention [0003] The purpose of the present invention is to provide a method for fully tem...
