报告题目：Treatability and dimensional stability of impregnated woods

摘要：

Effect of several impregnating agents on treatability and dimensional stability improvement of three lesser-used wood species grown in North Kalimantan Province, namely nyatoh (Palaquium spp.), sepetir (Sindora spp.), and pisang putih (Mezzettia spp.) has been studied. Impregnation was carried out by vacuum-pressure and then followed by soaking in each impregnant solution in hot condition. Impregnating agents used consist of the conventional phenol formaldehyde (PFK), low molecular weight phenol formaldehyde (LmwPF), polyethylene glycol-1000 (PEG), succinic anhydride (SA), and sodium silicate (SS). Results showed that impregnation applied can significantly improve dimensional stability of wood, except for impregnation with SS. Succinic anhydride and PEG are the best impregnating agent in term of improving wood dimensional stability, but SA can easily wash off from wood. Sodium silicate at 10% concentration is not recommended as impregnating agent. Sepetir wood has greater treatability than other species. The PFK and LmwPF have a different phenomenon on treatability and dimensional stability improvement.
