摘要:
The invention relates to a graphite-containing moulded body (5) which can be obtained by a method in which graphite particles (6) are mixed with at least one solid additive (7) to form a mixture which comprises at least one inorganic additive, a mixture consisting of an inorganic additive and an organic additive or more than 10 wt.% of an organic additive and the thus obtained mixture is subsequently compressed. Said at least one additive (1) which is used comprises particles having an average diameter (d 50 ) of between 1 and 500 μm, determined in accordance with the ISO 13320 standard.
摘要:
The invention relates to a laminate which comprises at least one layer of a compressible, graphitic material and at least one further layer of a compressible, graphitic material or a layer of a ceramic material and in which there is a permanent bond between the materials and the materials are joined by means of a surface-active, bonding substance from the group consisting of organosilicon compounds, metal soaps and perfluorinated compounds.
摘要:
The invention relates to a layered composite material which is suitable, in particular, for use in a redox flow battery, comprising at least one layer of a textile fabric and at least one graphite-containing moulded body which is obtained by a method in which graphite particles are mixed with at least one solid organic additive to form a mixture and the thus obtained mixed is then compressed.
摘要:
The invention relates to a layered material which consists of at least one ply of a graphite-filled polymer material or a ply of a ceramic material and in which a non-detachable connection is present between the materials, and the materials are connected by means of an interface-active, adhesion-promoting substance from the group consisting of organosilicon compounds, metal soaps or perfluorinated compounds.
摘要:
A latent heat storage device is formed with a carrier substrate formed of expanded graphite material. Phase change material is infiltrated in the graphite material. A thin graphite sheet provides for the functional heat conductivity into and out of the carrier substrate. After the phase change material (PCM) is infiltrated in the carrier substrate, a density of the infiltrated carrier substrate exceeds its starting density by a ratio of at least 3:1 or 4:1 or more. The volume dimensions of the infiltrated the carrier substrate remain substantially unchanged. In the alternative, the latent heat storage device may also have a PCM coating layer on a thin carrier substrate, wherein the phase change material is interspersed in a carrier matrix forming the PCM coating layer. The composite device may be very thin.
