Effect of tree age, thickness and depth of black poplar timbers on color change and wettability of wood after accelerated weathering

Saeed Hasani; Mohammad Talaei poor; behzad baziyar; Amir Homan Hemmasi; Saeed Mahdavi

Volume 38, Issue 2 , June 2023, , Pages 141-154

https://doi.org/10.22092/ijwpr.2023.360163.1732

Abstract
  AbstractIn this study, black poplar (Populus nigra) cut from Zanjan province was used in two age groups of 18 and 38- year-old. Timbers with thicknesses of 4, 5 and 6 cm were prepared from each age group. The prepared timbers were modified during the heat treatment process (Thermowood) at a constant ...  Read More

Abstract
  In this study, the effect of cellulose nanofibers and silicon nanoparticles on the properties of nanocomposites made with polyvinyl alcohol was studied and the physical, mechanical and morphological properties of nanocomposites were investigated. Samples were prepared by casting with different ratios ...  Read More

Comparison of the efficiency of two adsorbents activated carbon and beech wood powder copper-modified in removing sulfide ions (S-2) from the black liquor of Kraft pulp and paper

Masoumeh Mollaei; Mazaher Moeinaddini; Nematollah Khorasani; Mohammad Azadfallah; Amirhooman Hemmasi

Volume 35, Issue 4 , January 2021, , Pages 376-391

https://doi.org/10.22092/ijwpr.2020.343056.1617

Abstract
  Sulfide ions (S-2 ) derived from Na2S remaining in black liqueur are the source of H2S gas production along the black liquor recovery cycle in the Kraft pulp and paper industry. In this study, we tried to prevent the production of H2S by removing the mentioned ions from black liquor by using of synthesized ...  Read More
