(FR) MILIEU FILTRANT ET SON PROCÉDÉ DE FABRICATION
(KO) 필터여재 및 이의 제조방법
Abstract:
(EN) An embodiment of the present invention relates to a method for manufacturing a filter medium, comprising the steps of: preparing a fibrous medium; exposing the fibrous medium to plasma to activate the surface of the fibrous medium with a hydroxyl group; and coating the hydroxyl group-activated fibrous medium with a fluorine silane-based water repellent to afford a super-water repellent layer coated filter medium.
(FR) Un mode de réalisation de la présente invention concerne un procédé de fabrication d'un milieu filtrant, comprenant les étapes consistant à : la préparation du milieu fibreux; l'exposition du milieu fibreux au plasma pour activer la surface du milieu fibreux avec un groupe hydroxyle; et l'enrobage du milieu fibreux activé par un groupe hydroxyle avec un hydrofuge à base de silane fluoré pour obtenir un milieu filtrant enrobé de couche super-hydrofuge.
(KO) 본 발명의 일 실시예는 필터여재의 제조방법에 관한 것으로, 섬유상 여재를 준비하는 단계; 상기 섬유상 여재를 플라즈마에 노출시켜 상기 섬유상 여재 표면을 하이드록실기로 활성화하는 단계; 및 상기 하이드록실기로 활성화된 섬유상 여재를 불소 실란계 발수제로 코팅하여 초발수층이 코팅된 필터여재를 제조하는 단계; 를 포함하는 것을 특징으로 하는 필터여재 제조방법을 제공한다.
