The Parameters of EVA Film for Laminated Glass(2)
I have wrote an post The Parameters of EVA Film for Laminated Glass(1), now we are going to finish the topic.
The Parameters you should care about when check the quality of EVA FILM:
1. Radiation Resistance
Check with post: The Parameters of EVA Film for Laminated Glass(1)
2. Humidity Resistance
Placing the laminated glass with EVA FILM samples vertically inside the climatic chamber and maintaining them for two weeks at a temperature of 50 degrees and 95% relative humidity. Water condensation on the surface of the laminated glass samples is allowed.
No bubbles or opaqueness are noted in the spacer in any of the laminated glass samples tested. (Bubbles only appear along the edges, but at less than 15mm from it.)
3. Impact Resistance
For example: 45kg shot-bag drop from 1200mm height. It remains unbroken or broken, but no shear or opening is allowed within the test piece, through which a 75mm diameter sphere can pass freely.
4. Ultraviolet Radiation Blocking Rate
Tested by the Light Spectrum Meter.
5. Tensile Strength
Tested by the Universal testing machine
6. Elongation
Tested by the Universal testing machine
7. Adhesive Strength
Tested by the Universal testing machine
8. High Temperature Resistance
Boiled by hot water
9. Visible Light Transmission Rate
Tested by the Light Spectrum Meter
Hope it’s helpful to you.
