Abstract
(EN)
In order to aromatize soluble plastic materials, the perfume is arranged as a chemical product or as a composition consisting of the mixture of natural essential oils and chemical products, and dissolved in the solvent of the given plastic material; said perfume-solvent solution is applied to the plastic material to be perfumed by spraying, while in permanent movement of the mass, sheet or object, and further evaporation of the solvent with recovery of said solvent or by simple aeration with loss of the solvent; to aromatize plastic materials which are not soluble in certain solvents but which are swellable therein, the perfume is dissolved in the solvent capable of swelling the plastic material; the plastic material to be perfumed is incorporated to said solution so that it remains immersed during a preset time duration until it reaches the desired swelling, and the solvent is recovered at a later stage, leaving the perfume within the plastic material. Application to the aromitization of plastic materials.
(ES)
Para aromatizar plásticos solubles, se dispone el perfume en forma de producto químico, o en forma de composición como mezcla de aceites esenciales naturales y productos químicos se disuelve en el disolvente del plástico determinado; esta solución perfume-solvente se aplica al plástico a perfumar por pulverización en constante movimiento de la masa, lámina u objeto y posterior evaporación del disolvente con recuperación del mismo o por simple aireación con pérdida del disolvente; para aromatizar plásticos insolubles en determinados disolventes pero sí hinchables en ellos, el perfume se disuelve en el disolvente capaz de hinchar el plástico; a esta solución se le incorpora el plástico a perfumar de forma que quede sumergido durante un determinado tiempo hasta alcanzar el hinchamiento deseado y posteriormente se recupera el disolvente dejando el perfume en el seno del plástico. De aplicación en la aromatización de plásticos.
(FR)
Afin d'aromatiser des matières plastiques solubles, on utilise le parfum sous une forme de produit chimique ou sous une forme de composition comprenant un mélange d'huiles essentielles naturelles et de produits chimiques, et qui est dissous dans le solvant du plastique en question; cette solution parfum-solvant est appliquée à la matière plastique que l'on souhaite parfumer par pulvérisation en mouvement constant de la masse, feuille ou objet puis évaporation ultérieure du solvant avec récupération de celui-ci ou par simple aération avec perte du solvant; pour aromatiser des plastiques insolubles dans certains solvants mais gonflables dans ceux-ci, le parfum est dissous dans le solvant pouvant gonfler le plastique; à cette solution on incorpore la matière plastique parfumée afin que cette dernière reste immergée pendant un laps de temps prédéterminé jusqu'à atteindre le gonflement désiré, puis on récupère le solvant et le parfum reste au sein de la matière plastique. Application à l'aromatisation de matières plastiques.
