Teak wood ( Tectona grandis ) as an important forest resource in Indonesia has been processed to furniture large quantities fulfill increasing need of both local and international consumers. To satisfy the demand for products, teak supplied from State forests (Perhutani) Community plantations. harvested at shorter age rotations (7–10 years) than Perhutani (40–60 years). This paper discusses occurrence characteristics juvenile based on density, shrinkage, bending strength (modulus rupture -...
Short rotation teak wood has low quality especially in dimensional stability and durability. Furfurylation treatment was applied to improve technological properties of the short wood. The purpose study durability through furfurylation treatment. sapwoods (Plus Perhutani Biotrop teaks) were treated impregnation process 45% furfuryl alcohol (FA) 5% tartaric acid as catalyst followed by heated oven at 120 °C for 16 h under nitrogen atmosphere. Dimensional characterized volumetric swelling,...
Sengon (Falcataria moluccana Miq.) tree offers a wood of low quality and durability owing to its density thin cell walls. This study aimed improve the properties sengon by making magnetic, producing new functions, characterizing magnetic wood. Each sample was treated using one following impregnation solutions: Untreated, 7.5% nano magnetite-furfuryl alcohol (Fe3O4-FA), 10% Fe3O4-FA, 12.5% Fe3O4-FA. The process began with vacuum treatment at 0.5 bar for 2 h, followed applying pressure 1 h....
Many wood processing industries use short rotation teak, which has lower quality especially in durability and dimensional stability. Heat treatment is an eco-friendly method to improve stability of wood. The objectives the study were investigate effects thermal modification on chemical composition, colour, as well coating's performance after accelerated weathering long teak for exterior utilization. In this study, samples heated oven at 220 °C 20 h under nitrogen atmosphere. Results showed...
Lactic acid (LA), citric (CA), and glycerol (G) are renewable environmentally friendly chemicals that could improve the qualities of short-rotation teak (SRT) woods. This study investigated effect thermal chemical modification using 20% aqueous solutions (w/w) LA, CA, G their mixtures in same composition on physical mechanical properties SRT wood. The impregnation process was initiated by vacuum for 1 h pressure (12.2 bar) 2 h, followed (150 °C) treatment 6 wood samples after being removed...
Abstract Differences in characteristics between sapwood and heartwood of short-rotation teak are a significant obstacle to valorize mixed boards containing both types wood. Chemical thermal modifications attractive methods improve the quality short rotation wood allowing homogenization properties like decay resistance, dimensional stability color. However, no data available on difference density teak, as well effect such treatments achieve homogeneity. Density profiling is important assess...
Jabon (Anthocephalus cadamba) is a fast-growing wood species that widely utilized for light construction and other purposes in Indonesia. The objectives of the current study were to determine effects monoethylene glycol (MEG) SiO2 nanoparticles (nano SiO2) impregnation treatment on dimensional stability density jabon identify characteristics impregnated wood. Wood samples immersed water (as untreated), MEG, 0.5% MEGSiO2, then by applying 0.5 bar vacuum 60 min, 2.5 pressure 120 min. results...
Mangium (Acacia mangium Willd.) is a fast-growing wood that widely grown in Indonesia. The impregnation method needed to improve the qualities of wood. In this study, TiO2 nanoparticle (79.17 nm) was produced using hydrothermal method. purpose study analyze effect on density and dimensional stability effectiveness presence degrading pollutants. samples (2 cm × 2 cm) were placed inside tube. solutions included water (untreated), 1% nanoparticle, 5% nanoparticles. analyzed for density, weight...
For many wood cutting processes, the interest of high-speed tool steels and tungsten carbides remains very important because their good edge accuracy easy grinding.The wear steel carbide is an economic parameter.Wood extractives silica have a potential adverse effect on wear.Rapid chemical wearing due to corrosion mechanical has been attributed presence in composites.This paper presents characteristics SKH51 K10 caused by extractive abrasive materials present lesser-known Tapi-Tapi...
The quality of finished wood products depends on the its coating layer. An important indicator for evaluating is Adherence paint surface. purpose this research was to analyze effect surface roughness and viscosity acrylic paints (pure copolymer) wettability long short rotation teaks. Wood with various degrees prepared by sanding abrasive papers P120, P240, P360 grits. Different composition between water (w/w) 100:0, 90:10, 80:20, 70:30. teak surfaces measured using a sessile drop contact...
Merkusii pine wood (Pinus merkusii) was extensively planted throughout Indonesia, where it is only indigenous in northern Sumatera, by the Dutch during colonial times. The demand for this species, especially domestic market, has increased notably, despite its limited durability regarding decay resistance. purpose of study to investigate occurrence juvenile and mature on merkusii analyze radial features from pith bark based density, shrinkage, static bending modulus rupture elasticity, fiber...
The surface free energy (SFE) of woods and their wettability are important characteristic for wood painting. No information is available regarding the SFE Indonesian tropical woods. purpose study was to determine 10 tested in this were fast-growing species from plantation teak, sengon, jabon, pine, natural forest ramin, meranti, mahagony, camphor, keruing, ebony. Surface roughness measured by a profilometer, while determined sessile drop method. values calculated based on Rabel Wettability...
Jabon (Anthocephalus cadamba) is a fast-growing wood with low quality due to its density and strength. The can be increased by modifying the through impregnation various chemical compounds. In this study, jabon was impregnated solution of Fe immersed in strong base (NaOH) or weak (NH4OH) form magnetite (Fe3O4) in-situ. This study analysed use NaOH NH4OH synthesising magnetic evaluated wood’s characteristics. process began vacuum −0.5 bar for 0.5 h then pressure 1 2 h. samples subsequently...
