Embodiment 1
[0029] Embodiment 1: as figure 1 As shown, the flexible substrate 1 is a PET film with a thickness of 75 μm; SiO x Layer 2 thickness 25nm, SSO x Layer 3 has a thickness of 5 nm; Ag(Au) layer 4 has a thickness of 14 nm, and Ag:Au=85:15 (weight ratio). Product performance: Visible light transmittance is 82%, radiation rate is 0.14, and ultraviolet light absorption rate is 95%.
Embodiment 2
[0030] Embodiment 2: as figure 2 As shown, the flexible substrate 1 is a PET film with a thickness of 23 μm; SiO x Layer 2 thickness 25μm, SSO x The thickness of layer 3 is 2 nm; the thickness of Ag(Au) layers 4 and 6 are both 9 nm, and Ag:Au=85:15 (weight ratio). The thicknesses of the ITO layers 5 and 7 are both 85nm.
[0031] Product performance: Visible light transmittance is 78%, radiation rate is 0.11, and ultraviolet light absorption rate is 90%.
Embodiment 3
[0032] Embodiment 3: see image 3 and Figure 4 , the real-time monitoring method process such as image 3 As shown in the block diagram, using the Figure 4 The multi-target magnetron sputtering roll-to-roll coating machine implementation of shown prior art, Figure 4 When the middle receiving (putting) material roller 23 rotates clockwise, it is a receiving roller, and when the receiving (releasing) material roller 21 rotates counterclockwise, it is a receiving roller. 1. Four light-emitting diode emitting probes (i.e., light-emitting probes 24) are evenly distributed horizontally on one side, and four light-receiving probes 20 are correspondingly arranged on the other side of the base film 1. The emitted light of the probes 24 is perpendicular to the running direction (plane) of the base film 1 , select the light transmittance of four wavelengths of 470nm, 560nm, 660nm, and 880nm for real-time monitoring, and the infrared transmittance of 880nm wavelength can judge wheth...
