As result,...
The compatibility of oil-palm-trunk fibers and cement was investigated. Cold-water hydrothermal carbonization treatments were applied on the fibers, then hydration temperature measured to observe compatibility. Calcium chloride (CaCl2), as an accelerator, added at 1.5, 3.0, 4.5 6.0% weight. results showed that cold-water treatment reduced hemicelluloses ash content, thereby increasing Fourier transform infra-red analysis functional groups untreated treated almost identical, indicating...
Pyrolysis gas chromatography-mass spectrometry (Py-GCMS) is a simple, rapid, and reliable analytical technique to assay lignocellulose biomass. This study aims analyze the chemical content of various ages platinum fast-grown teak wood using PyGCMS coupled with interdependence multivariate analysis. Fifty-eight peaks were shown in pyrogram originating from carbohydrates, lignin, extractive derivatives. Along age, showed higher carbohydrate derivatives heartwood than sapwood. Compared grown...
This research deals with low molecular weight-phenol formaldehyde (LMW–PF) impregnation on sepetir (Sindora spp), nyatoh (Palaquium spp.), and pisang putih (Mezzettia spp.) woods to determine the effect of different anatomical structure weight percent gain dimensional stability improvement. The wood samples were impregnated using LMW–PF solutions 7, 8, 9, 10, 11% concentrations (w/w), vacuum-pressured (–98 kPa, 15 min, 350 4 h), re-immersed in 80°C for 3 h. According findings, reduced...
AbstractThe aim of this study was to improve the properties 15-year-old short rotation teak wood using a succinic acid (SA) treatment without excessively increasing weight gain. The samples were classified as sapwood (SW) and heartwood (HW). Samples immersed in 10% concentration SA solutions (w/w), followed by vacuuming at -50 kPa for 30 minutes, applying 7 M Pa pressure 2 hours. They then analysed specific gravity (SGs), dimensional stability, including tangential/radial ratio (T/R Ratio)...
Abstract The objective of this research was to determine the wood basic properties eight years-old fast-growing teakwood ( Tectona grandis – Platinum teak wood), in radial direction stem. anatomical features examined showed semi-ring porous and general, they had a similarity those conventional wood. ray cell proportion increased along with distance from pith area. size vessel tended change outer part. (R) tangential (T) shrinkage improvement compared five R T shrinkages were 2.89% 6.2%,...
Recent studies of fast growing species grown in PT. Sari Bumi Kusuma, Central Kalimantan, show that based on their fiber dimensions there are five species, namely Endospermum diadenum , Dillenia spp., Adinandra dumosa Adiandra sp., and Nauclea junghuhnii with good potential for pulp paper production. The length those wood was more than 2,200 µm average. This the physical properties, chemical contents to predict quality. result shows all were classified medium high density category. All into...
