Hygric and Thermal Insulation Properties of Building Materials Based on Bamboo Fibers

2017 
This study focuses on manufacturing bio-insulation fiberboards from bamboo fibers and bone glue, modified with sodium lignosulfonate. The microstructure of these boards is investigated by mercury intrusion porosimetry. The porosity and average pore size of boards are decreased; however, the specific pore surface is increased with the presence of bio-glues in boards. The hygric properties are examined through kinetics of water vapor sorption at equilibrium states. The thermal conductivity and bending properties are also studied. The thermal conductivity is dependent on relative humidity levels and moisture content of the fiberboards. The bending property is increased with 30% (w/w) of mixture glue between bone and sodium lignosulfonate in boards.
