Problems solved by technology

[0002] The existing low-E film structure is generally S-M-S or S-M-S-M-S (that is, medium-metal-dielectric or medium-metal-medium-metal-medium), in which silver, copper, aluminum, etc. are generally used as the metal, and silver is mainly used for the medium; Oxides of titanium, zirconium, zinc, indium, tin, tungsten, etc., and nitrides of titanium, silicon, etc. are used. The combination of these film materials has a poor effect on blocking ultraviolet light.
At the same time, due to the poor corrosion resistance of silver, it brings a lot of inconvenience to the control of the production process, product transportation, storage and secondary processing of the product, and is also unfavorable to the service life of the product.
In addition, the lack of effective real-time monitoring means in the production of existing low-e film, resulting in unstable production process and product quality, needs to be improved

Abstract

A flexible low radiation window film formed by plural layers coated on transparent flexible base material, wherein the Ag(Au) film is silver alloy comprising Ag and doped 15-20 wt% of homogeneous distribution Au. the real time window film monitoring method comprises arranging a plurality of light-emitting diode emission-receiving transducers on the material collecting roller on the multiple target magnetron sputtering coiling film plating machine in cross direction, whose output signals are magnified by amplifier and converted into digital information, and sent to one-chip computer for comparing and processing, and connected to the upper position through the interfaces, the target power output is controlled thus realizing the real time control for the continuous layer's film thickness.
