Improvement of the fire-proofing and fire-resistance properties ofPV modules for building's exterior walls

摘要

Research was conducted to investigate the fire-proofing andfire-resistance properties of a curtain-wall-type PV module for abuilding's exterior walls. Several types of fluoroplastics were found tohave a potential for application as fire-proofing cell encapsulationmaterials that can replace EVA. By using a cone calorimeter, decreasesin total heat evolved and delays in ignition time were seen as thelimiting oxygen index of cell encapsulation materials increased in theorder of EVA, and fluoroplastics-A and B. From the test results of fireresistance tests using actual PV modules, the flames were found to beweaker with fluoroplastics compared with the case of EVA. Those alsocorresponded with the result of a cone calorimeter. Fluoroplastics werefound to be more advantageous as fire-proofing cell encapsulationmaterials
