摘要:
La frabication du garnissage consiste en : l'élaboration de fils à partir de fibres ; la formation d'un soubassement (11) sous forme de nappe continue ; la formation d'une fourrure (12) de fibres sur l'une des faces de ladite nappe. En outre l'élaboration de la nappe est conduite de manière à développer dans celle-ci une hétérogénéité transversale de nature à conférer à ladite nappe une tendance à s'enrouler sur elle-même, la configuration de structure du support est déterminée par une opération de découpage d'une pluralité de fentes (13) répétées selon la direction d'élaboration de la nappe. Les deux lèvres de chaque fente (13) s'écartent l'une de l'autre, la bande de textile se trouvant entre deux fentes voisines s'enroule sur elle-même et forme des tronçons cylindriques (15) avec la fourrure dressée sur la face convexe. On a ainsi une alternance d'éléments cylindriques (15) et d'ouvertures (19). La présente invention est plus particulièrement destinée à l'épuration des eaux résiduaires, à la transformation de tout jus organique, à la séparation de fluides polyphasiques...

A filter assembly includes a filter pad comprising fibers including natural, synthetic and/or hybrid fibers. A stabilizer frame formed of a non-metallic material may be imbedded in the filter pad. The stabilizer frame may be configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration. In accordance with a particular embodiment, the filter pad may be comprised of at least first and second fibrous mats that are coupled together. In this embodiment, the stabilizer frame may be disposed between and coupled with the first and second fibrous mats.

Non-halogenated monomers that can be polymerized into flame retardant polymers, and processes to produce the monomers and polymers is provided. In a simplest aspect, there is provided a monomer composition that can comprise a) a group derived from one of a (meth)acrylic acid, (meth)acrylamide, or vinylbenzene, b) a polyphosphate moiety, and c) an amine species. In the monomer composition, the ethylenically unsaturated monomer of (a) is covalently bonded directly or through a linking group to the moiety of b), forming a precursor monomer unit. The amine species of c) is in complex with the precursor monomer unit. The polymer can be a homopolymer of the monomer composition, or a copolymer of the monomer composition having varying a), b) and c). In one embodiment, the polymer can additionally comprise ethylenically unsaturated monomers not covalently bonded to a polyphosphate moiety.

A method of manufacturing a porous fluid treatment element, e.g. a filter element, includes forming a layered structure having at least two layers and subjecting the layered structure to at least a heat treatment. The step of forming a layered structure includes forming a first layer including particulate matter including at least a binder and applying a second layer including particulate matter including at least a binder directly onto the first layer on a first side thereof. The step of forming a layered structure further includes applying at least one of radiation and heat to at least the first side of the first layer prior to applying the second layer.

The invention furthermore pertains to a method of manufacturing a filter according to one or both of the above mentioned aspects.
摘要:
The present invention relates to a method of producing a cellulose-fiber flat structure, the method including obtaining a cellulose-fiber flat structure by filtering a fine cellulose-fiber dispersion containing fine cellulose fibers having an average fiber diameter of 4 to 100 nm, using a filter material having a water permeability of not more than 100 ml/m 2 ·s and an initial tensile modulus of 20 MPa or greater. The present invention is able to produce a cellulose-fiber flat structure by efficiently recovering fine cellulose fibers from a dispersion containing fine cellulose fibers having an average fiber diameter at the nano level. The method of producing a cellulose-fiber flat structure can also be applied to a continuous process.

摘要:
The objective of this invention is to provide a spiral filter, on a surface of which a plurality of prominences and depressions are alternatively formed at regular intervals, like ribs of a folding fan, and a method and a device for producing the same using a bite (25), reciprocating by converting a high-speed rotating motion into a high-speed reciprocating motion. The spiral filter has a relatively large surface area, and is applied to a contact oxidation process of decomposing organic contaminants contained in wastewater, in addition to filtering dust and contaminated gases contained in atmospheric air. At this time, microorganisms contained in the wastewater are easily and firmly attached to the surface of the spiral filter, a bio-layer is scarcely separated from the surface of the spiral filter, and attachment of the bio-layer to the surface of the spiral filter is maintained for a relatively long term.
