摘要:
A process for removing contaminants from a fiber reinforcement material, the process comprising: (a) feeding a fiber reinforcement into a heated vessel, (b) passing the fiber reinforcement through the heated vessel, (c) heating a source of fluid medium, (d) feeding the heated fluid medium from (c) into the heated vessel having a passageway in the heated vessel for allowing the heated fluid medium from (c) to enter into the heated vessel, (e) passing the heated fluid medium through the heated vessel; wherein the heated vessel has a passageway for allowing the heated fluid medium from (c) to exit the heated vessel, and (f) contacting the fiber reinforcement passing through the heated vessel with the heated fluid medium passing through the heated vessel such that any contaminants present in or on the fiber reinforcement is sufficiently reduced to provide a purified fiber reinforcement exiting the heated vessel.

Ein Verfahren zum Reinigen von zumindest mit organischen Stoffen behafteten gebrauchten Faserwertstoffen, wobei die mit Wasser oder einem Wasser enthaltenden Fluid vermischten Faserwertstoffe in einem Hydrothermalreaktor (14; 114; 214) erhitzt werden, ist gekennzeichnet durch die folgenden Schritte: a) Zuführen eines Wertstoffstroms (W) von künstlich erzeugte Mineralfasern aufweisenden Faserwertstoffen zu einer Zerkleinerungseinrichtung (10); b) Zerkleinern der Faserwertstoffe des Wertstoffstroms (W); c) Vermischen der zerkleinerten Faserwertstoffe mit dem Wasser oder mit dem Wasser enthaltenden Fluid zu einer fließfähigen Pulpe; d) Beaufschlagen der Pulpe mit thermischer Energie unter Überdruck für einen vorgegebenen Zeitraum; e) Entspannen des Überdrucks auf Umgebungsdruck und Abführen des dabei entstehenden Dampfes.
摘要:
A method and apparatus for locally raising the temperature of a material to facilitate chemical reactions or processes related to growth or removal of the material, utilizes an electrode to apply, in the presence of a growth or removal medium, a controlled succession of thermal spikes or shockwaves (6) of varying energy, on the scale of a few nanometers to several hundred micrometers. The duration of the thermal spikes or shockwaves ranges from a few picoseconds to several hundred nanoseconds. The medium may be a cryogenic liquid. Other growth media, including liquids, solids, gases in critical or non-critical state, and mixtures of liquids/solids, solids/gases, and liquids/gases, may also be employed. The electrode may be an electrode emitter tip (1) with an anode (2) above workpiece (4) on platform (3) in the medium. Circuit (5) includes power source (7) with switch (8) controlling voltage pulse duration applied across tip and anode to produce shockwaves.
摘要:
The present invention provides a method for manufacturing an aerogel blanket, wherein a surface modification process is performed under acid conditions while using a non-toxic catalyst, so that a solvent substitution process or a washing process may be omitted to simplify the manufacturing process, and the collapse of a gel structure due to shrinkage is prevented and the efficiency of surface modification is high even when atmospheric pressure drying is performed, so that an aerogel having excellent thermal conductivity and degree of hydrophobicity may be manufactured, and provides an aerogel blanket manufactured by the method, thereby having low thermal conductivity and a low moisture impregnation rate since a hydrophobic group is uniformly formed inside a substrate.
摘要:
Plant (1) for recovering carbon or glass fibres from composite materials comprising said fibres in a polymer matrix comprises a tunnel kiln (2) along which said materials are conveyed inside containers (6), in which said tunnel kiln comprises a pyrolysis zone (3), in which said composite materials are subjected to a pyrolysis process in an atmosphere devoid of oxygen, a gasification zone (3) in which said materials are subjected to a gasification process in the presence of oxygen, and an intermediate separating zone (5), placed between the pyrolysis zone (3) and the gasification zone (4), in which a plurality of second injecting devices (23) to deliver nitrogen to said intermediate zone (5) is provided, so as to prevent the atmosphere of the pyrolysis zone (2) coming into contact with the atmosphere of the gasification zone (3).
摘要:
A finishing composition and method for applying the composition to a fabric (10) woven from glass fibers or from a blend of glass fibers and other fibers such as polyamide or polyester. Such finishes significantly enhance the flex life of woven glass fabrics (10) by improving the acid and alkali corrosion resistance of the fibers. The finish, which comprises fluoropolymer and epoxy resin, can be loaded into the fabric in multiple baths (11). Filtration products can be fabricated from the finished fabrics and they are especially useful for making filter bags (1) used in the bag houses (2) for central power generating stations and similar industries.
