Title
(EN) COMPOSITION FOR REDUCING EVAPORATION AT SITES BOTH ON LAND AND OPEN WATER
(FR) COMPOSITION POUR REDUIRE L'EVAPORATION SUR DES SITES TERRESTRES ET D'EAU LIBRE
Abstract
(EN)
A blended composition of water conservation measures applied to save water at both on-land and open water sites is disclosed as combining with a higher fatty alcohol constituent, alternatively either a slaked lime constituent or, in substitution thereof, an acidified gypsum constituent containing sulfuric acid. The inorganic constituents provide ionic compounds which when contacted by water release certain ions diffusing faster than others, whence a charge-procuring mechanism causing individual particulate aggregations of the compositions to repel one another results. An amorphous and unemulsified form for the higher fatty alcohol is suggested as important to mitigation or risks of impairing water infiltration into treated soil.
(FR)
L'invention concerne une composition mélangée, destinée à la conservation des eaux, qui s'applique sur des sites terrestres et d'eau libre pour économiser l'eau. Cette composition combine un constituant d'alcool gras supérieur avec, soit un constituant de chaux éteinte, soit, à la place de celui-ci, un constituant de gypse acidifié contenant de l'acide sulfurique. Les constituants inorganiques fournissent des composés ioniques qui, lorsqu'ils entrent contact avec l'eau, libèrent des ions qui diffusent plus rapidement que d'autres, ce qui produit un système d'apport de charges dans lequel les agrégats particulaires individuels de la composition se repoussent mutuellement. Une forme amorphe et non émulsionnée de l'alcool gras supérieur permet de limiter considérablement les risques de dégradation de l'infiltration d'eau dans le sol traité.
