Abstract
The wise use of insulation materials in buildings not only reduces energy consumption but also reduces greenhouse gas emissions and increases the thermal comfort of the room. Oil palm wood fiber and ramie fiber have great potential as a basis for the thermal insulation bio board. The thermal stability of the base material is essential to study. The purpose of this study was to analyze the thermal characteristics of oil palm wood and ramie fiber as raw material for the thermal insulation bio board. Thermal characteristics were tested by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Oil palm wood fiber and ramie fiber as the base material get treatment before being tested. Oil palm wood fiber is immersed in 120 ℃ hot water for 30 and ramie fiber in 5% NaOH solution at the same time. The results of the TGA analysis show that the thermal stability of OPW fibers with treatment is better, 248 ℃ than the OPW without treatment at 235 ℃. Likewise, ramie fiber with 5% NaOH mixture has better thermal stability, 280 ℃ than untreated ramie fiber, which produces a peak temperature of 272 ℃. DSC analysis showed that the maximum temperature peaks occurred at 409 ℃ and 408 ℃ for OPW and hemp fiber treated, respectively. The thermal stability of fibers will increase with pretreatment compared to untreated fibers.
