Hydrothermal treatment is an efficient and environmentally friendly method of enhancing the dimensional stability durability wood. The destructive effects formic acetic acids generated during thermal treatment, on other hand, are known to have a negative impact wood strength. As result, hydrothermal in different buffered media (acidic, neutral, alkaline buffer) was performed this study mitigate...

Rambutan seeds were subjected to SC-CO₂ extraction at 35 MPa, 45 °C to obtain defatted rambutan seed flour. Its physicochemical properties before and after treatment with alkali solution using 0.075 N NaOH were investigated. Alkali-treated flour had a significant increment in bulk density, swelling power, water adsorption capacity, emulsion capacity and stability but a reduction in turbidity, s...

regarding the nutritional value and availability of acorns in west and southwest of iran, the effects of partial substitution of wheat flour with acorn flour was investigated. wheat flour was replaced by treated acorn flour in the formulation of sponge cake and the quality characteristics were evaluated. density of cakes was increased with increasing the acorn flour. as the substitution degree ...

To increase the loading amount of modifier in wood, a simple and universal approach was developed to improve its permeability. The generated pores wood can be backfilled with modifiers, thereby improving function wood. This study aimed permeability Eucalyptus urophylla using urea solution. treated under different conditions, including concentration, treatment duration, temperature, before after...

In this work, the influence of three types of styrene maleic anhydride (SMA) oligomers on the adhesion of polystyrene wood plastic composites (WPC) was investigated. The composites were processed on a twin-screw co-rotating extruder below 200°C using 20 wt% of wood flour. The styrene maleic anhydride with different content of maleic anhydride groups, 30%, 25% and 20% (w/w) and levels of 1, 2 an...

in this research, effects of concentration and time of silane treatment of rice straw flour on the morphology and mechanical strengths of rice straw flour/polypropylene composites were investigated. tri ethoxy vinyl silane (c8h18o3si) with 98% purity in two concentrations of 5 and 10%, that each concentration had two immersion times including, 45 and 90 min for using treatment rice straw flour....
