Sputtering targets such as ATO (Chinese invention patent CN 101851739A), ZAO (Chinese invention patent CN101481790), GZO (Chinese invention patent CN101188149, CN101575207), YZO (Chinese invention patent CN101580384), AZO (Chinese invention patent CN101913856A), off-line method In the early production of heat insulating glass, the vacuum evaporation method was used to deposit the film layer. This method has less investment and quick results, but has the disadvantages of uneven film layer, poor firmness, and mechanical properties such as wear resistance.
The magnetron sputtering method has a high degree of automation, easy film control, and stable product quality. However, this process requires a large investment and a long production cycle. Like the online method, it is difficult to promote in general small and medium-sized enterprises.
The transparent insulating glass coating loses visible light transmittance and infrared reflectivity
