Experimental and theoretical analysis of the alkali impregnation of eucalyptus wood
(American Chemical Society, 2009-05)
Wood impregnation is crucial in any pulping process. The impregnation of chips of eucalyptus wood by a liquor of constant alkali concentration is here analyzed. A mass balance that considers kinetics of the main reactions ...
Demulsification of water/sunflower oil emulsions by a tangential filtration process using chemically impregnated ceramic tubes
(Elsevier B.V., 2007-02-15)
A tangential filtration process was implemented in this study using porous ceramic tubes made of alpha-alumina produced by the slip-casting technique. These tubes were sintered at 1450 degrees C and characterized by mercury ...

Supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with insecticidal terpene ketones: Impregnation yield, crystallinity and mechanical properties assessment
(Elsevier Science, 2017-06)
In this contribution, supercritical CO2-assisted impregnation of LDPE/sepiolite nanocomposite films with two insecticidal terpene ketones (thymoquinone and R-(+)-pulegone) is investigated, as a strategy to enhance the ...
Nano lithium silicates as flame-retardant impregnants for Pinus radiata
(Sage Publications Ltd, 2011-09)
Aqueous solutions of nano lithium silicates with 5.5/1.0 and 7.5/1.0 silica/alkali molar ratios were used to impregnate Pinus radiata. To obtain these impregnants, a solution of 3.5/1.0 SiO2/Li2O molar ratio was used; this ...
ETHYL SILICATES WITH DIFFERENT HYDROLYSIS DEGREE LIKE NON-FLAMMABLE IMPREGNATING MATERIAL FOR WOOD
(Universidad del Bío-Bío, 2008)
Effect of bituminous impregnation on nonwoven geotextiles tensile and permeability properties
(ELSEVIER SCI LTD, 2011)
Geosynthetics interlayer systems are effective techniques to control reflective cracking in damaged pavements. It comprises the inclusion of nonwoven geotextiles between the damaged layer and the new overlay of the pavement ...
Dimensional stability, fire performance and decay resistance in wood impregnated with Alkylalkoxysilanes
(World Scientific, 2013-11)
The wood, very heterogeneous and complex material, changes its volume by water absorption or desorption causing swelling or shrinkage and also it can be degraded both by action of microorganisms and fire; the above-mentioned ...
Dynamical aspects of hardwood impregnation
(De Gruyter, 2000-02)
The phenomenon of axial liquid penetration in hardwoods is modeled through two different mechanisms: in one of them the driving force is taken to be the empty space that remains unfilled inside the material; in the other ...
