| Abstract |
Polyurethane Foam (PUR) is used as insulation, frame and buffer of cold storage because of excellent insulation, construct, process and adhesion performance. However, it can emit deadly toxic gas in case of fire which can cause massive casualties. Recently the product in urethane that Polyisocyanurate Foam is used as sandwich panel core, improved product of flame retardant performance, has been increased. But it`s not easy to distinguish the flame retardant performance between PUR and PIR at a construction site. Therefore cone-calorimeter test and gas hazard test are performed to confirm the performance of materials according to the standard set by the Ministry of Land. In this study, infrared spectroscopic analysis were performed for PIR and PUR that have similar shape to each other but different fire resistance performance. and this study tried to consonance analysis between PIR and PUR that have different infrared absorption spectrum by measuring the spectrum and statistic method. As a result, effective analysis method demonstrates what easly can be applied in site. |
