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)...
Samama wood (Anthocephalus macrophyllus (Roxb) Havil) is a fast-growing and lesser-utilized species that has inferior properties; therefore, its quality needs to be improved. This research aimed determine the effect of citric acid impregnation at high curing temperatures on dimensional stability mechanical properties wood. Citric solution with 10% concentration (w/w) was impregnated into samples by vacuum-pressure method (–0.5 cmHg, 30 min; 0.7 MPa, 3 h), followed process 140°C, 160°C, 180°C...
Abstract Linear Low-Density Polyethylene (LLDPE) is a type of plastic with high percentage solid waste and hardly degradable. The characteristics LLDPE such as toughness low density have the potential to be an alternative aggregate substitute for applications in non-structural mortar composites. purpose this study was determine suitable formulation substitution against silica sand application adhesive Vinyl Acetate/Ethylene (VAE) surfactant (1.2 wt%) used improve interface between cement...
Particleboard is a product of wood technology engineering made particles and other lignocellulosic materials which are bonded with synthetic adhesives. As an information, utilization natural adhesive for particleboard still limited. This study aimed to determine the influence hybrid from citric acid sucrose properties composed Sengon veener by-products sorghum stalk. The content used was 15% 25% that calculated dry weight particles. mixture ratio both were 100:0, 75:25, 50:50, 25:75, 0:100...
