Processing method for rapidly tempering low-e glass

Abstract

The invention provides a processing method for rapidly tempering low-e glass. The processing method comprises the following steps of: 1, cutting the glass; 2, edging the glass; 3. downwards placing a low-e film in a heating furnace; 4, preheating and heating the glass; and 5, air cooling the glass. The processing method has the beneficial effects that the low-e film of the glass faces downwards, the problems of low temperature raising speed, non-uniformity in heating, damage to equipment and service life of the glass during heating are solved; electric energy is saved, the cost is further saved; the production efficiency is improved; and the quality of the glass is improved and the yield of the glass is increased.

Description

technical field [0001] The invention belongs to the field of glass processing, in particular to a processing method for rapidly tempering low-e glass. Background technique [0002] At present, the production of tempered glass is divided into two modes: chemical tempering and physical tempering. Chemical tempering is to place the glass in molten alkali salt, so that the ions with smaller radius in the surface layer of the glass exchange with the ions with larger radius in the molten salt, and finally form compressive stress layers on both surfaces of the glass, and form tension stress layers inside the glass. The stress layer can achieve the purpose of improving the mechanical strength and temperature shock resistance of the glass. This method is generally used for tempering small glass such as mobile phone screens and display device glass, and it seriously pollutes the environment. It cannot meet the requirements for tempering architectural glass, let alone process low-e gl...
