Effects of Ozonization on the Durability of Fiberboard Bonded with Isocyanate Resin and Phenol Formaldehyde Resin
Fiberboard poly-methylene diphenyl diisocyanate durability acetylation ozone
2010/3/4
Untreated fibers and acetylated fibers were ozonized and used to make fiberboards. The effect of ozonization on the durability of the boards bonded with poly-methylene diphenyl diisocyanate (PMDI) and...
Characterization of platinum–iron catalysts supported on MCM-41 synthesized with rice husk silica and their performance for phenol hydroxylation
MCM-41 rice husk phenol hydroxylation
2010/1/19
Mesoporous material RH-MCM-41 was synthesized with rice husk silica by a hydrothermal method. It was used as a support for bimetallic platinum−iron catalysts Pt–Fe/RH-MCM-41 for phenol hydroxyla...
Phenol Removal from Aqueous Solution through Hollow Fiber Membrane Extraction
Hollow Fiber Extraction Phenol
2009/3/25
In this work, mass transfer mechanism was studied for 50%TBP( in kerosene)-Phenol-Water as the working system in different hydrophobic microporous hollow fiber modules. The effect of different opera...
Effects of Various Treatments for Improving Bondability on the Properties of Fiberboard Bonded with Phenol Formaldehyde Resin
fiberboard phenol formaldehyde resin acetylation penetration
2009/3/5
In order to improve the bonding of fiberboard, the penetration of phenol formaldehyde (PF) resin was prevented. The means of preventing penetration were acetylation of wood fibers and the addition of ...
