Wear Behavior of Alkali-Treated Sorghum Straw Fiber ...
The appli ion of wood-plastic composites is growing rapidly in the fields of corrosion and aging. The present study investigated the effect of alkali-treated with NaOH concentrations of 0.5 2.5 4.5 and 6.5% sorghum straw SS fiber on the wear resistance of polyvinyl chloride PVC composites under simulated seawater and acid rain conditions.【Get Price】

In this paper Anticorrosive fir was liquefied in phenol and the liquefied wood was used to produce adhesive by resinifi ion. The effect of resinifi ion time resinifi ion temperature mrNaOH/P molar ratio of NaOH/liquefied wood and mrF/P molar ratio of formaldehyde/liquefied wood on resinifi ion was investigated by orthogonal experiments in term of the viscosity solid content and ...【Get Price】

IMPROVED INTERFACIAL BONDING OF PVC/WOOD-FLOUR COMPOSITES BY ...
Mannich reaction and was used as an interfacial modifier in PVC/wood-flour composites. PVC/wood-flour composites were prepared from treated wood flour and PVC by melt compounding. The tensile and impact strengths water absorption and morphologies of composites were investigated. Furthermore the coupling effects of lignin amine and【Get Price】

Effect of alysts and sodium hydroxide on glyoxal-treated wood
The wood treated with NH 4 2 S 2 O 8 displayed the greatest WPG after five leaching tests which indi es the higher anti-leachability of NH 4 2 S 2 O 8 in wood modifi ion with glyoxal because of its effective alysis in cross-linking between glyoxal and wood components. Fig. . WPG of treated wood after each leaching test.【Get Price】
