  • In the study, test was carried out to compare the flame retardant performance for the specimen of MDF wood to which field flame retardant treatment (post processing flame retardant) is applied, which is coated with flame retardant film of 5 companies, locally distributed, and MDF wood (nontreated, flame retardant film non-coated) to which aqueous or oil-based fire-retardant paint is applied. As a result of combustion test of MDF wood which was coated with flame retardant film of 5 companies, 2 products showed suitable values in 4 criteria, but other 3 products showed 10~40 % disqualification rate. In regard of characteristics of fire-retardant paint, oil-based fire-retardant paint is better than aqueous fire-retardant paint in flame retardant performance criteria, but MDF wood to which oilbase fire-retardant paint was applied was shown to have higher toxicity index grade than MDF wood to which aqueous fire-retardant paint was applied relatively.

  • To figure out the problems of flame retardant treatment (FRT) on wooden buildings, field investigation and analysis of statistical data are performed. After FRT on historical wooden building, efflorescence and exfoliation showed most often. These problems appeared especially on column, rafter and Ga-gu (Ingredients for supporting structure of a roof) which are liberally spreaded. To compare before and after FRT, analyzed 20 elements using P-XRF. In this process, found sulfur which informs FRT. This helped set up nondestructive assay. Through this process, confirmed field application by analysis residue component of Songgwang-sa Temple.
