One of the important factors that should be considered in architecture is the fire resistance of the materials used. This study, it is aimed to increase the fire resistance of particleboards, which are widely used in architecture. For this purpose, it is aimed to improve the fire resistance by using a new type of impregnation material obtained by modifying boron compounds with rosin additive. Within this context, particleboard samples prepared in accordance with TS 642 ISO 554 were sized according to ASTM-E 160-50. Combustion tests of prepared samples were done in accordance with ASTM-E 160-50 E, and the values obtained through the tests on the basis of burning time, weight loss ratios, FsC, SC, Gp temperatures were compared with the control samples. As a result, it was observed that average temperature values of FsC, SC decreased by 5%, Gp decreased by 1,8%, weight loss was reduced by 0,5% and the combustion period was increased by 2%. This case can be taken into account in the field where particleboard is used with high fire risk in architecture.

Mimaride göz önüne alınması gereken önemli faktörlerden birisi de kullanılan malzemelerin yangın dayanımıdır. Bu çalışmada, mimaride yaygın olarak kullanılan yonga levhaların yangın dayanımlarının artırılması amaçlanmıştır. Bu maksatla borlu bileşiklerin kolofan katkısı ile modifiye edilmesinden elde edilen yeni tip emprenye maddesi kullanılarak yanma direncinin artırılması hedeflenmiştir. Bu kapsamda TS 642 ISO 554’e uygun oalrak hazırlanan yonga levha örnekleri ASTM-E 160-50’ye uygun olarak boyutlandırılmıştır. Hazırlanan numunelerin yanma deneyleri ASTM-E 160-50 E’ye göre yapılmıştır. Deneylerde yanma süresi, ağırlık kaybı oranları, AKY, KKY, KHY sıcaklıları belirlenerek kontrol numuneleri ile karşılaştırılmıştır. Sonuç olarak yeni tip emprenye maddesininAKY, KKY sıcaklık değerlerinde ortalama %5, KHY sıcaklık değerlerinde % 1,8, ağırlık kaybında %0,5 düşüş ve yanma süresinde %2 oranında artış sağladığı ölçülmüştür. Mimaride yangın riski yüksek olan yonga levha kullanım alanlarında bu durum dikkate alınabilir.
