Examples
Example Embodiment
[0028]Example one
[0029]Visual inspection
[0030]Test equipment and methods
[0031]Micro thermal stage HS82 (thermal analysis stage + polarized display lens), digital measuring projector CPT-3025A, black plate.
[0032]Visual inspection, colorless and transparent, without any defects.
[0033]Use illuminator and black board for visual inspection. Tilt the sample 20-45 degrees to observe whether there are foreign objects, bumps, bends, scratches and other phenomena. If visual inspection cannot be judged, use a magnifying glass.
Example Embodiment
[0034]Example two
[0035]Brightness, chroma, haze test
[0036]Test equipment and methods
[0037]Test equipment: Quartz glass plate, micro heating stage, haze transmittance tester AT-4725, darkness meter 6801; gloss meter 4454-45; electronic thickness gauge C1216; cutter JDC-15M-10
[0038]Use the solution-washed glass and the spectrophotometer and haze meter to calibrate, and then peel off the light release film with a 30mm peel off the heavy release film on the laminated glass plate to test the brightness, color and haze.
Example Embodiment
[0039]Example three
[0040]Adhesion test
[0041]Test equipment and methods
[0042]Testing equipment: quartz glass plate, tensile testing machine, silicone roller, shore hardness tester, cutter JDC-15M-10
[0043]Cut the sample 15mm, peel off the light release film, and paste it on the cleaned glass plate, peel off the heavy release film, attach the support film, and then press the pressure roller three times by hand. After 30 minutes in the room, use a tensile machine for adhesion Test, test conditions, peeling angle 180 degrees, pulling force speed 100mm / min.
