Abstract

The use of recycled carton as an alternative material for the layer of composite board may increase the board strength properties. The objective of this research was to find out the influence of face and back layer types on the quality of produced boards. Materials used in this study were wafer made from sengon wood (Paraserianthes falcataria L. Nielsen), water based polymer isocyanate adhesive, and several kinds of cartons such as duplex carton, recycled carton, and waste of corrugated board. The composite board was produced with the target density of 0.65 g/cm3 and the resin solid content of 6% based on oven dry weight of particle, face and back layers. The results are as follows : 1) Utilization of carton layers improved the dimensional stability and bending strength of board; 2) Composite board with recycled carton layer fullfilled the Japanese Industrial Standard (JIS) A-5908-1994 for wafer board type in terms of density, water content, and modulus of rupture (MOR) in lengthwise and widhtwise of board but, did not fullfill that for veneered particled board type; 3) The presence of those layer material types decreased internal bond of the board. Keywords : composite board, face and back layer types, recyled carton

Abstract

Agricultural fibers are currently used as a substituted resource to wood-based products. One of agricultural fibers that has been developed and become a resource for panel products is coir (coconut fiber). The purpose of this study is to evaluate the quality of veneered composite board made of coir and recycled polyethylene (RPE). The target density of board samples was 0.7 g/cm3. The board construction type is core type composite board (three layers). Veneers from Meranti (Shorea sp.) were used as face and back layers and coir was in the core layer. RPE composition was 50% based on coir particle and veneers oven dry weights. Recycled plastics were placed in three layers, 30% on the face and back layers, and 70% in the core layer. The coir sizes were under 1 cm, 1 cm, 5 cm, 10 cm, and 10 cm up (along coir size). The composite board samples were tested by JIS A 5908 – 1994. Each parameter was measured in three replications. The research results obtained are as follows : (1) Veneered composite boards made of coir and RPE fulfill the JIS A 5908 standard in term of density, thickness swelling after 2 and 24 hours of water immersions, modulus of elasticity, modulus of rupture and internal bond, and (2) The coir size did not significantly affect the properties of composite board. Keywords: veneered composite board, coir size, recycled polyethylene

Abstract

Cement and gypsum bonded cellulosic fiber reinforced materials are ultimately ideal ecological building products. Their capability to use industrial coproducts and wastes as both their matrix material make its reinforcement also environmentally sustainable products. The objective of this study was to evaluate the effect of proportion cement-gypsum and curing autoclave time on the properties of cement gypsum board from core-kenaf. Three levels of proportion cement and gypsum were applied, namely; 40:60, 50:50, and 60:40, where cements contain at face-back layers and gypsum contain at core layers. Five levels of curing autoclave time were applied, namely ; conventional curing 2 weeks (control), curing autoclave 2, 4, 8, and 16 hours. CaCl2 3% and Borax 2 % was used as an accelerator and retarder. The physical and mechanical properties of cement-gypsum board were observed in according to JIS A 5417-1992. The results show that the physical and mechanical properties were gain on proportion of cement-gypsum 60:40 with 8 hours curing autoclave. Key words : Core-kenaf, Cement-gypsum board, Autoclave References

Abstract

This study was aimed to analyze the resistance of composites board made from wafer and carton or paper overlaid on drywood termite and subterranean termite. Materials used in this study were wafer from sengon wood (Paraserianthes falcataria L. Nielsen), water based polymer isocyanate adhesive, veneer, and several kind of carton and paper such as duplex carton, recycle carton, corrugate board, and waste of cement sack. The target density was 0.65 g/cm3, while the resin solid content was 6%. The result of this study showed that no significantly different on infection rate of drywood termite among of composite board types and solid wood. The weight loose of composites board were 1.2–3.8%, while solid wood was 2.7%. Composites board more favorable to infection Macrotermes gilvus than solid wood. The weight loose of composites board were 19.3 – 28.8%, while solid wood was 12.6%. Key words: Composites board, drywood termite, subterranean termite
