Fast-growing wood such as jabon (Anthocephalus cadamba) and ganitri (Elaeocarpus sphaericus) which has a less harvest period about 6–7 years, usually has inferior wood characteristics, namely low density, strength and durability. This study aim was to analyze the effect of melamine formaldehyde-furfuryl alcohol (MFFA) and nano-SiO2 impregnation on color alteration and wettability values of A. cadamba and E. sphaericus wood. The impregnation solution treatments were consisted of untreated (water treated), MFFA, and MFFA nano-SiO2 0.5%. The impregnation process was comprised by vacuum of 0.5 bar for 60 min and continued by applying a pressure of 2 bars for 120 min. The results showed that large color change (ΔE) occurred in jabon and ganitri after being treated by 0.5% MFFA and MFFA nano-SiO2. The content of nano-SiO2 inside the MFFA solution can increase the color brightness (decrease ΔE) in both wood species. The treatment of MFFA and MFFA nano-SiO2 0.5% also had a significant effect on the contact angle and he K values. The optimum treatment for the wettability of jabon and ganitri wood was MFFA nano-SiO2 0.5%.

摘要

Fast-growing wood such as jabon (Anthocephalus cadamba) and ganitri (Elaeocarpus sphaericus) which has a less harvest period about 6–7 years, usually has inferior wood characteristics, namely low density, strength and durability. This study aim was to analyze the effect of melamine formaldehyde-furfuryl alcohol (MFFA) and nano-SiO2 impregnation on color alteration and wettability values of A. cadamba and E. sphaericus wood. The impregnation solution treatments were consisted of untreated (water treated), MFFA, and MFFA nano-SiO2 0.5%. The impregnation process was comprised by vacuum of 0.5 bar for 60 min and continued by applying a pressure of 2 bars for 120 min. The results showed that large color change (ΔE) occurred in jabon and ganitri after being treated by 0.5% MFFA and MFFA nano-SiO2. The content of nano-SiO2 inside the MFFA solution can increase the color brightness (decrease ΔE) in both wood species. The treatment of MFFA and MFFA nano-SiO2 0.5% also had a significant effect on the contact angle and he K values. The optimum treatment for the wettability of jabon and ganitri wood was MFFA nano-SiO2 0.5%.
