Manufacturing method of tri-silver LOWE capable of being tempered

Abstract

The invention discloses a manufacturing method of tri-silver LOWE capable of being tempered. The method comprises the following four steps of respectively determining the consumption ratio of processgas in a process cavity; manufacturing a film layer; grinding film plating glass; performing tempering treatment on the film plating glass. The LOWE manufactured according to the technical scheme provided by the invention belongs to glass with good characteristics of relatively good infrared ray reflection capability of a silver low-radiation film, low film layer surface radiation rate, low sun shielding coefficient, low reflection rate and the like. In addition, for the surface mechanical performance of the product, high hardness and high oxidization resistance in the tempering process are realized; a zirconium oxide layer is added to the outermost layer to be used as a protection layer; the protection layer is obtained by forming a layer of zirconium oxide with the thickness being 5nm to30nm through sputtering spraying by a magnetron sputtering method. The protection layer can achieve a good protection effect on the film surface; in the subsequent processes of processing, transportation, storage and the like, the mechanical damage such as film surface scratch damage and press damage can be effectively prevented; meanwhile, the oxidization speed of the silver layer can be delayed. The manufacturing method can be widely applied to film plating glass production and processing industry.

Description

technical field [0001] This technology relates to the application field of architectural coated glass, and more specifically, it is a method for making toughened triple-silver LOWE. Background technique [0002] Off-line LOWE uses vacuum magnetron technology to coat a thin layer of nano-scale film on the glass substrate by physical sputtering. The film material is mainly composed of alloys, nitrides or oxides. [0003] The first off-line LOWE that appeared in the 1980s was a non-steel product. The disadvantage is that the energy saving effect is poor and it cannot be processed in different places. In the 1990s, the toughenable LOWE technology made a major breakthrough, making the lowe temperable in different places a reality. [0004] In the existing three-silver-coated low-emissivity coated glass on the market, the glass can only be processed by first tempering and then coating. This is because the silver layer after tempering is commonly thermally migrated and the glass s...

Problems solved by technology

However, the people and the market have higher and higher requirements for products. People hope that the visible light part will become more and more transparent, but the sunshade performance will continue to decrease. This poses new challenges to LOWE products. Double silver LOWE partly solves this problem. Contradictory, but market requirements are unlimited
