Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, in particular to a processing glue spraying device for producing and processing tempered glass. Background Art

[0002] Tempered glass is a safety glass. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc., which can ensure that the bonding between the two layers of tempered glass is more stable. Physical tempered glass is also called quenched tempered glass. It is to heat ordinary flat glass in a heating furnace to a temperature close to the softening temperature of the glass (600°C), eliminate the internal stress through its own deformation, then remove the glass from the heating furnace, and use a multi-head nozzle to blow high-pressure cold air to both sides of the glass, so that it can be quickly and evenly cooled to room temperature, and then tempered glass can be made. This kind of glass is in a stress state of internal tension and external compression. Once it is partially damaged, stress release will occur, and the glass will be broken into countless small pieces. These small fragments have no sharp edges and corners and are not easy to hurt people.

[0003] Tempered glass is obtained by cutting ordinary annealed glass into required sizes, then heating it to about 700°C, close to the softening point, and then cooling it quickly and evenly. During the production process, tempered glass needs to be sprayed with processing glue.
