Abstract

L'invention concerne des fibres de charbon actif dotées d'une fonction de purification d'air et un article fabriqué à partir de celles-ci. Les fibres de charbon actif sont préparées au moyen d'un procédé comprenant les étapes suivantes : le chargement, en parties en poids, de 90 à 160 parties de fibres de polyimide et de 40 à 70 parties de fibres de charbon actif dans un pulvérisateur, le broyage et le tamisage de celles-ci de façon à obtenir une poudre ; l'ajout de la poudre résultante et de 10 à 20 parties d'un tensioactif, de 6 à 13 parties de particules d'argent à l'échelle nanométrique et de 10 à 15 parties d'un agent antimicrobien dans un mélangeur à ultrasons, et le mélange et l'agitation pour obtenir un mélange ; puis la soumission de celui-ci à un traitement à l'état fondu, et l'ajout de celui-ci dans une extrudeuse à vis pour le filage pour préparer les fibres de charbon actif dotées d'une fonction de purification d'air. L'article est préparé au moyen du procédé suivant : le tissage des fibres de charbon actif résultantes dans un tamis filtrant, puis la pose du charbon actif et d'un tissu non tissé soufflé à l'état fondu, et enfin la fixation de celui-ci avec un cadre en alliage d'aluminium pour obtenir l'article. Les fibres de charbon actif et l'article fabriqué à partir de celles-ci présentent une bonne fonction de purification de l'air, et présentent les avantages d'une résistance aux température élevées et basses, d'un retard de flamme, d'une isolation thermique et d'une stabilité dimensionnelle, et présentent également la fonction de stérilisation. Le charbon actif peut décomposer des gaz toxiques et nocifs, tels que le formaldéhyde, le benzène, et le gaz amine, sous l'action de la lumière solaire ou de la lumière d'éclairage de manière hautement efficace.
