Hygroscopicity of wood after polyethylene glycol (PEG) impregnation and/or heat treatment
2013 - IRG/WP 13-40623
The hygroscopicity of wood after polyethylene glycol (PEG) impregnation and/or heat treatment was investigated by testing the water uptake, equilibrium moisture content (EMC) at various relative humidity levels, and contact angle of the poplar wood surface. The results showed that: (1) At the first moment, the heat treatment at temperatures lower than 160 ℃ did not reduce the water uptake be...

The Physical Properties of Heat Treated Fir Wood and Outdoor Durability
2014 - IRG/WP 14-40677
Wood might be easily susceptible to degrade by biotic and abiotic factors. Therefore, wood should be protected from fungi, insects and other degradation factors by applying treatment methods. Especially, for the wood have used in the external environment. Chemical treatment methods have some disadvantages such as use of toxic chemicals (Arsenic and chromium) and treatability of refractory wood spe...

Efficacy of lignocellulosic materials for Removal of Cation and Anions from Industrial and Urban Wastewater
2016 - IRG/WP 16-50321
The adsorption of Ca, Zn, Na, Cd (II), Cr (III) and No3 ions from industrial and urban wastewater and aqueous solutions by poplar (Populusnigra) sawdust, cotton linter, zeolite and expanded perlite were examined on the basis of a batch adsorption technique. The results revealed that application of sawdust, cotton linter, perlite and zeolite are effective in improving elimination of Ca, Zn, Na ions...

Thermodynamic properties of furfurylated wood during moisture adsorption process
2018 - IRG/WP 18-40828
Furfurylation of wood seems a promising wood modification method considering the wide raw material source of furfuryl alcohol (FA) and overall performance of FA modified wood. However, the modification mechanism of furfurylation is still not clear and needs further investigation. In this study, poplar (Populus cathayana Rehd.) samples with the size of 1(R) mm × Ф4 mm, were impregnated with ...
