Among them, LOW-E (LOW-Emissivity) glass has been attracting attention because it has an excellent heat insulating effect and good light transmittance. Currently, LOW-E glasses are divided into two categories: on-line LOW-E glass and off-line LOW-E glass.

In addition, the first functional layer 13, the second functional layer 17 and the third functional layer 21 are all silver layers or silver-copper alloy layers, which can additionally reflect infrared heat and prevent the heat from passing through. In addition, each layer can be formed only by adopting a magnetron reactive sputtering deposition method during the production of the three-silver coated glass, so that the multiple entering and exiting of coating equipment in the production process can be avoided, the production process is simplified, the production cost can be reduced, and the production efficiency can be improved.

Each film layer is formed by magnetron sputtering deposition at room temperature, but after each layer is deposited, post-treatment is required to be performed on the glass substrate 10 on which each layer is formed. The post-treatment comprises, for example, tempering the glass substrate 10 on which the layers are formed, wherein the tempering temperature is 650 to 700 ℃, and the tempering time is about 1 to 10 minutes; or annealing the glass substrate 10 on which the respective layers are formed, wherein the annealing temperature is 400 to 650 ℃, and the annealing time is 20 minutes to 2 hours.
