Abstract

The use of wood filler is vital in wood finishing. However, the most commercial wood fillers available in the market are made of chemical solvent-based resins, such as polyurethane and nitrocellulose. These products contain volatile organic compounds. This study examines performance of alternative and commercial wood fillers. The alternative wood fillers were made from the mixture of putty powder and organic resins, i.e. shellac, acrylic and polyvinyl acetate. The wood fillers were tested on tusam, jabon and rubber wood by assessing their physical, mechanical and chemical performances in comparison with the most commercial wood filler, i.e. nitrocellulose wood filler. Samples of three wood species were treated by spreading them with various wood filler solutions. Weight and dimensional changes due to treatment were determined in wet and dry sample conditions. Chemical and scratch resistance of the wood filler films were also tested to determine their chemical and mechanical performance. Color similarity of the wood filler treated samples and control were evaluated using the CIELab color system. The effect of treatment were varied according to wood species. Tusam samples possess greater weight and dimensional gains than those of jabon and rubber wood samples. All organic wood filler formula could effectively protect wood from water intrution, comparable to that of the commercial wood filler (WF). The organic wood fillers had higher scratch resistance, less chemical resistance, and better color appearance than the commercial WF.

Abstract

The domestic need for phenolic-based wood adhesives is high, but the material is currently imported, then altenative adhesivesare needed. This paper studies the characteristics of mahogany tannins and effective formulation of alternative adhesives made frommahogany bark extracts of mixture tapioca flour and industrial flour as extender applied to composite or glued products. The barkof mahogany was cut to the size of 2 cm x 1 cm x 0.1 cm, extracted with hot water (70–80°C) with a ratio of 1:3 (w/w,material/water) for 3 hours with two repetitions. After extraction product was filtered, and the filtrate was copolymerized usingresorcinol and formaldehyde under alkaline and room temperature conditions to produce resin tannin resorcinol formaldehyde(TRF). The blend of tapioca flour and industrial flour (1:1, w/w) as an extender was used in the TRF application to manufacturecomposite products. The results showed that this mahogany bark liquid extract could be copolymerized to form a resin which thenapplied as a wood adhesive in a cold pressing process. The optimum adhesive formula was a mixture of 0.25 mol of resorcinol and1-mol formaldehyde, with a 15% extender, and a catalyst (NaOH 40%) of 4% of the total weight of the adhesive formulation.The characteristics of mahogany tannin adhesives resemble those of the exterior type phenolic group.

Abstract

Oil palm trunk is lower in dimensional stability, density, physical, and mechanical properties than other wood species. Efforts to overcome the weakness of the oil palm trunk properties could be conducted through densification with hot pressing and chemical adhesive addition. This paper studies optimum composition of Tannin Resorcinol Formaldehyde (TRF) in its application for improving the quality of oil palm trunk. The tannins were water extracted at 75°C and further copolymerized with resorcinol and formaldehyde. TRF was studied through functional group analysis using infrared spectroscopy and cristallinity test using X-ray diffraction. The TRF adhesive was applied through compregnation process. Results showed that reactivity of tannins in bark of Acacia mangium was 65.82%, the optimum adhesive composition of TRF (v/v) was = 1:0.05:0.05 with solid content of 8.33%, 0.09% free formaldehyde, and the degree of crystallinity was 10.92%. Tannin extract has a specific character on the wave number corresponding to the characteristics possessed by the imported tannin acacia standard. The presence of new functional groups and an increase in absorbance intensity of uptake at several wave numbers through infrared spectroscopy analysis on TRF as well as compregnated oil palm trunk indicate the occurrence bonds attributted by ether and methylene bridges to TRF and chemical compound on oil palm trunk. Oil palm trunk after compregnation significantly increased its density by 104.61%, hardness became 6 fold, and decreased the thickness swell to 85.98%. The oil palm trunk after compregnation also increased in quality from a wood strength class V to a wood strength class III, then, its potential for manufacturing exterior products.

Abstract

Laboratory-scale manufactured hardboard made of Saccharum Sponaneoun Grasses (SSG), Empty Oil-palm Bunches (EOPB), and andong bamboo is potentially developed. However, initial experiment shows the hardboard did not meet Japanese Industrial Standard (JIS) and International Standard Organization (ISO) for hardboard. This paper observes modification of the hardboard to satisfy the standards. Modification includes adding alkali concentration during pulp cooking and changing the additives composition. Result shows modification can enhance the hardboard quality to satisfy JIS and ISO requirements. Fiber mixture of SSG pulp and andong/betung bamboo pulp was cooked in 10.5% alkali concentration; and 12% alkali concentration for EOPB pulp. Additives composition used were tannin-resorcinol formaldehyde/TRF adhesive, alum, and activated charcoal; without wax emulsion. The mixture of SSG pulp (50%) + EOPB pulp (50%) was the most prospective for hardboard, followed by SSG pulp (100%) solely; SSG pulp (50%) + andong bamboo pulp (50%); and SSG pulp (50%) + betung bamboo pulp (50%) as the lowest prospects. The least prospective fibrous material (betung bamboo) are expectedly be improved by using more TRF adhesive, nano-size activated charcoal and cross-linking agents.

Abstract

The science advancement in this century is such that in the future it will enter the nano technology. More specifically in the forest products field, the nano technology that can be developed is among others nano carbon derived from lignocelulosic stuffs. In relevant, this research aims to provide information and technology on the charcoal processing from lignocellulosic stuffs into nano carbon. The lignocellulosic stuffs used in this research consisted of teak wood and bamboo, further carbonized into charcoal at 400-500°C using drum kiln. The resulting charcoal was examined of its physical and chemical properties, crystalinity degree and dielectric characteristics, and then purified by re-carbonizing it at 800°C for 60 minutes. Prior to the purification, the charcoal sustained the doping (intercalation) process with Zn, Ni and Cu metals each respectively. After the purification, the charcoal was ground to very tiny particels using HEM (high energy machine) device for 48 bours. In this way, the charcoal with high crystalinity was yielded, and further sintered using spark plasma at 1,300 C into the nano carbon. The qualities and structure of all the resulting carbon (carbonized charcoal, re-carbonized charcoal, intercalated charcoal and sintered nano carbon) were evaluated using nano scale device (Py-GCMS, SEM-EDX and XRD), and examined as well of their dielectric characteristics. In turns out that the best quality charcoal was obtained from teak wood charcoal carbonized at 800°C, intercalated with Ni atoms at the ratio 1:5. The resulting charcoal afforded high crystalinity (78.98%), low electric resistance (0.17 2), and high conductivity 175.52 2'm Qualities of the corresponding nano carbon (after sintering) were such that its crystalinity spectaculary reached 81.87%, resistance (R) 0.01 & with very bigh conductivity 1067.262'm'. The nano carbon that resulted seems favorably prospective for bio-censor, bio-battery, and bio-electrode. Accordingly futher related research deserves carrying out.
