Abstract :
The main objectives of this study were to evaluate the biodegradation behaviour of experimental particleboard bonded with modified 30 % of PVOH, 70 % of Oil palm starch and 3 % of nano silicon dioxide (SiO2). Boric acid at 2 % was also added as a cross-linker to PVOH in modified oil palm starch to enhance decay resistant for the samples. All the particleboards were evaluated by soil burial, borer and fungal strains tests. The samples were then compared with particleboard bonded with native oil palm starch and commercial urea formaldehyde (UF). The results indicated that particleboards bonded with modified PVOH/Oil palm starch were more resistant than particleboard bonded with their native starch and thus can be used as a potential binder for green particleboard in future. The SiO2 also showed a significant effect towards modified oil palm starch as compared to their native oil palm starch and commercial binder.

اهداف اصلي اين مطالعه بررسي رفتار زيست تخريب تخته خرده چوب هاي تجربي پيوندي با 30٪ PVOH سيليكن (SiO2) بوده است. اسيد بوريك در 2 به عنوان يك پيوند دهنده متصل به PVOH در نشاسته نخل روغن اصلاح شده به منظور افزايش مقاومت در برابر انبساط نمونه ها اضافه شد. تمام تخته خرده چوب ها با استفاده از تست هاي كشت خالص، خراش و قارچ بررسي شدند. سپس نمونه ها با تخته خرده چوب با نشاسته نخل نفتي و تجاري اوره فرمالدئيد (UF) مقايسه شدند. نتايج نشان داد كه تخته خرده چوب با اصلاح PVOH / روغن نشاسته نخل نخاعي مقاوم تر از تخته خرده چوب با نشاسته بومي خود است و بنابراين مي تواند به عنوان يك اتصال دهنده بالقوه براي تخته خرده چوب سبز در آينده استفاده شود. SiO2 همچنين اثر قابل توجهي نسبت به نشاسته نخل نخل اصلاح شده در مقايسه با نشاسته نخل نفتي و تركيبي تجاري داشت.
