摘要:
A filter unit for the purification of air includes at least a first filter element, which contains granular, especially spherical, activated carbon as an adsorbent material, and at least a second filter element, which contains a combination of granular, especially spherical, activated carbon and activated carbon fibers as an adsorbent material. The filter unit is suitable especially for use in ventilation plants, ventilation systems, air-conditioning systems and the like.
摘要:
A method of processing spent ion-exchange resins contaminated with suspended particles, inorganic residues and/or organic foreign matter so as to render the resin ineffective for continued use, by which method this waste material can be processed to produce useful activated carbon particles instead of simply being dumped in a landfill. In accordance with the invention, granular spent organic ion-exchange resin having an ash content of from 5 to 30% is first dried, then carbonized under a substantially inert atmosphere at a temperature of 300 to 900° C., the inert atmosphere containing 0.2 to 4 volume percent oxygen up to 400° C., and finally activated at a temperature of at least 700° C. under a substantially inert atmosphere containing 3 to 50 volume percent steam.
摘要:
An adsorption filter material used especially for producing protective materials, such as NBC protective suits, has a first layer, a second layer, and an adsorption layer arranged between the first layer and the second layer. The adsorption layer has a first activated carbon layer with granular or spherical activated carbon particles. The first activated carbon layer additionally contains activated carbon fibers and/or the adsorption layer additionally contains a second activated carbon layer with activated carbon fibers.
摘要:
The adsorption filter has a highly air-permeable, three-dimensional carrier framework essentially stable in shape, to which a layer of granular adsorber particles with a diameter of 0.1 to 1 mm is affixed. The carrier framework can be composed of wires, monofilaments or stays, the distance between them being at least twice as great as the diameter of the adsorber particles. The carrier framework can also be a large-pore reticulated polyurethane foam which has a weight of 20 to 60 g/l and pores with a diameter of 1.5 to 3 mm. In spite of a very slight pressure drop, the filter performance is excellent.
摘要:
The present invention involves an inner shoe material with adsorbent properties, whereby activated carbon particles are fixed as the adsorbent material by means of an adhesive substance in a punctiform manner to the side of the material facing away from the foot. The inner shoe material of the invention can be designed as inside lining, insoles, slipsoles, as inner sole of the shoe or as a covering material for the inner sole of the shoe. The inner shoe material of the invention can e.g. be used for combat boots with integrated C-protection or for safety boots with protection against aggressive chemicals. The inner shoe material has the advantage that it exhibits a high degree of scuff resistance on the one hand and the adsorbent activated carbon is freely accessible to the substances to be adsorbed, on the other.
摘要:
A waterproof and moisture-conducting fabric comprising a base permeable to water vapor and sealed with a closed coating of a hydrophilic polymer. The sealing coating is advantageously a compressed foam of an acrylic resin modified with polyvinyl chloride or polyurethane. A second base may be laminated onto the sealing layer. Protective fillers such as lead compounds and carbon may be included in or on the coating. The fabric is suited for protective clothing articles such as rescue-at-sea garments and shoe uppers, and sleeping bags.
摘要:
Disclosed is an adsorbing material (1), particularly for producing protective suits, comprising an especially planar supporting material (2), an at least substantially air-impermeable, steam-permeable barrier layer (3), and an adsorbing layer (4). The baffler layer (3) is applied to the supporting material (2) and is used as an adhesive layer for the adsorbing layer (4) that is disposed on the face of the barrier layer (3), which lies opposite the supporting material (2). The baffler layer (3) is provided with a steam permeability of at least 20 l/m2 per 24 h at 25° C. and at a thickness of 50 μm.

摘要:
An odor filter for exhauster hoods, which filter includes an adsorption filter bed regenerable by washing. The filter bed is made of a highly air-permeable substrate material and an adsorbent affixed thereto in the amount of 50 to 400 g/l by an adhesive mass and has a mean particle diameter between 0.2 and 2 mm.
摘要:
A seal-free and frame-free odor and/or pollutant filter, e.g., in air conditioners and motor vehicles, having a self-supporting and elastic adsorption filter bed installed under slight compression in air supply ducts. The filter bed is made of a highly air-permeable substrate material and an adsorbent affixed thereto by an adhesive mass.
摘要:
A filter sheet material consisting of an air-permeable, pliable, especially textile support which is covered only partially with a uniformly distributed adhesive on which adsorber particles, especially active carbon beads, are fixed and the use of such filter materials containing active carbon as adsorbent for protective suits.
