Abstract

In this study, we have investigated the effects of impregnation materials (NH3)2P,Al2(SO4)3, K2CO3, CaCl, ZnCl2, on combustion properties of 3 ply laminated veneer lumbers (LVL) produced from fir (Abies bornmülleriana Mattf.) by using phenol-formaldehyde (PF), polyvinyl acetate (PVAc). The pressure - vacuum method was used for impregnation process. Combustion test was performed according to the procedure of ASTM-E 69 standards. As a result, ZnCl2 was found to be the most successful fire retardant chemical in LVL at PF adhesive. Since it diminishes combustion, the impregnation of LVL produced from fir by using PF adhesive can be advised to be impregnated by using pressure vacuum method.

Özet

Bu çalışmada, polyvinil asetat, (PVAc), fenol formaldehit (PF) tutkalı kullanılarak uludağ göknarından (Abies bornmülleriana Mattf.) 3 tabakalı olarak üretilen ve (NH3)2P, Al2(SO4)3, K2CO3, CaCl, ZnCl2, ile emprenye edilmiş malzemelerin yanma özellikleri araştırılmıştır. Emprenye işlemi basınç- vakum yöntemi kullanılarak uygulanmıştır. Yanma testleri ASTM-E 69 standartlarına göre yapılmıştır. Sonuç olarak yanmaya karşı en başarılı, çinko klorür ile emprenye edilmiş PF tutkallı LVL bulunmuştur. Yanma olayını geciktirdiği için, PF tutkalı kullanılarak Uludağ göknarından üretilen ve basınç – vakum metodu ile emprenye edilen LVL önerilebilir.
