초록
In this study, we measured that fire characteristics of four wood species using indoor finish materials. Wooden specimens were treated with fire retardant chemicals such as diammonium phosphate and potassium carbonate. The wooden specimens are Larix kaempferi, Pinus koraiensis, Cryptomeria japonica, and Chamaecyparis obtusa, which are used for indoor finish. The heat release rate (HRR) values of fire retardant treated woods were confirmed lower than that of untreated woods. For specific details, the HRR values of vacuum impregnated specimens for Pinus koraiensis and Cryptomeria japonica were measured lower than coatings. However, those of Larix kaempferi and Chamaecyparis obtusa showed the opposite effect to it. Total heat release rate values of all wooden specimens, vacuum impregnated were lower than coated specimens.
