Die Erfindung betrifft ein Filtergewebe für ein Brauereimaischefilter, gebildet aus Kett- und Schussfäden auf Basis von Kunststoffmonofilen mit einem Durchmesser von 0,25 bis 0,45 mm sowie in Kett- und/oder Schussrichtung in definierten Abständen eingearbeiteten weiteren Fasern, wobei die weiteren Fasern als Verstärkungsfasern aus einem gegenüber den Kunststoffmonofilen für die Kett- und Schussfäden reißfesteren und dehnungsärmeren Kunststoff parallel zu den Kett- bzw. Schussfäden in das Filtergewebe eingearbeitet sind.
摘要:
Porous and/or curved nanofiber bearing substrate materials are provided having enhanced surface area for a variety of applications including as electrical substrates, semipermeable membranes and barriers, structural lattices for tissue culturing and for composite materials, production of long unbranched nanofibers, and the like. A method of producing nanofibers is disclosed including providing a plurality of microparticles or nanoparticles such as carbon black particles having a catalyst material deposited thereon, and synthesizing a plurality of nanofibers from the catalyst material on the microparticles or nanoparticles. Compositions including carbon black particles having nanowires deposited thereon are further disclosed.
摘要:
The present invention relates to an apparatus for filtering a gas or liquid stream of impurities and to filter elements used in such an apparatus. The apparatus includes a closed vessel having a longitudinally extending length, an initially open interior, an input port at one extent and an output port at an opposite extent thereof. A partition located within the vessel interior divides the vessel interior into a first stage and a second stage. At least one opening is provided in the partition. A filter element is disposed within the vessel to extend from within the first stage. The filter element is made up of a carbon block filter media surrounded by a protective porous depth filter media.
摘要:
Filtering mediums are disclosed composed of fabric having a plurality of fibers where the surfaces thereof are coated with an ethylene chlorotrifluoroethylene copolymer. The fibers may also be extruded ethylene chlorotrifluoroethylene copolymer.
摘要:
A retaining material that can sufficiently maintain the function of retaining a pollution control element in a pollution control device at high temperature. In one aspect, the retaining material has a mat shape and contains inorganic fiber material, with the retaining material containing: a surface layer containing inorganic colloid particles; and an internal region positioned further to the inside than the surface layer, impregnated with inorganic colloid particles and organic binder; wherein the surface layer contains inorganic colloid particles at a higher concentration than the internal region; and the amount of inorganic colloid particles in the internal region is 1 mass% to 10 mass% based on the total mass of the retaining material.

摘要:
Die Erfindung betrifft ein Gewebe mit einer dehnbaren Gewebestruktur, welches ein hochelastisches und ein niederelastisches Garn aufweist, wobei die Elastizität des hochelastischen Garnes und des niederelastischen Garnes unterschiedlich ausgewählt sind, so dass beim bestimmungsgemäßen Dehnen eine gezielte Relativbewegung zwischen dem hochelastischen und dem niederelastischen Garn gegeben ist. Erfindungsgemäß enthält das niederelastische Garn ein Polyacetal, insbesondere ein Polyoxymethylen .
摘要:
An integrally formed multi-component structure is disclosed, the multi-component structure comprising a plurality of components, at least one of which is a three-dimensional bonded fiber fluid transmissive component comprised of a plurality of polymeric fibers bonded to each other at spaced apart contact points, the fibers collectively defining tortuous fluid flow paths, and wherein each component has an interface with at least one other component.
摘要:
The invention relates to a filter cloth for a filter, provided with a supporting surface, a fixing area for attachment to the filter and a filtration area which is borne on the supporting surface. An extensible fabric structure is provided at least in the filtration area in order to raise said filtration area from the supporting surface.Highly elastic monofilament threads are selectively incorporated into the fabric structure, at least in said filtration area, in order to produce a defined amount of elasticity.
