Title (EN) METHOD FOR PRODUCING AN EMULSIFIER AND METHOD FOR PRODUCING AN EMULSION
(FR) PROCÉDÉ DE FABRICATION D'UN ÉMULSIFIANT ET PROCÉDÉ DE FABRICATION D'UNE ÉMULSION.
Abstract:
(EN) The invention relates to a method for obtaining an emulsifier, at least consisting of mixing defibering dusts with or without the lignocellulosic fraction thereof with a fat such as a saturated fatty acid or an unsaturated fatty acid in a liquid state, such as linen oil or sunflower oil. The invention also relates to a method for making an emulsion of a first liquid, i.e. a fat, and a second immiscible liquid such as water. The method comprises mixing, relative to the total of the following components (a) and (b): (a) at least 40 % of defibering dust separated or unseparated from the lignocellulosic fraction thereof; (b) at most 60 % of the first liquid or fat such as a saturated fatty acid or an unsaturated fatty acid. The emulsion obtained by said method can particularly be used for rendering a plant material hydrophobic.
(FR) L'invention concerne un procédé d'obtention d'un émulsifiant qui consiste au moins à mélanger des poussières de défibrage avec ou sons leur fraction lignocellulosique et un corps gras tel que acide gras saturé ou acide gras insaturé, sous forme liquide, tel que par exemple huile de lin ou l'huile de tournesol. L'invention concerne également un procédé de fabrication d'une émulsion entre un premier liquide à savoir un corps gras et un second liquide tel que par exemple de l'eau, non miscible. Le procédé consiste au moins à mélanger par rapport au total des composants (a) et (b) suivants : (a) au plus 40 % de poussières de défibrage séparées ou non de leur fraction lignocellulosique. (b) au plus 60 % du premier liquide, ledit corps gras, tel que acide gras saturé et acide gras insaturé. L'émulsion obtenue selon le procédé trouvera une application particulière pour l'hydrophobisation de matières végétales.
