摘要:
A tin oxide-containing polymer composite material, a process for production thereof, and use thereof for production of tin-carbon composite material containing: an inorganic tin-containing phase; and a carbon phase. Additionally, a compound of formula (I): R1—X—Sn—Y—R2 (I), wherein: R1 is an Ar—C(Ra,Rb)— radical where Ar is an aromatic or heteroaromatic ring optionally containing 1 or 2 substituents; Ra and Rb are each independently hydrogen or methyl, or together are an oxygen atom or a methylidene group (═CH2); R2 is C1-C10-alkyl, C3-C8-cycloalkyl, or R1; or R1 together with R2 is a radical of the formula A: wherein: A is an aromatic or heteroaromatic ring fused to the double bond; m is 0-2; each R radical is independently selected from halogen, CN, C1-C6-alkyl, C1-C6-alkoxy, and phenyl, Ra, Rb are as in formula (1); X is O, S or NH; and Y is O, S or NH.
摘要:
A heating-venting-air conditioning unit for a cabin vehicle is positioned at the roof of the cabin vehicle. The unit has at least one blower having air channels connected to a suction side and a pressure side of the blower. At least one of the air channels is connected to the suction side to form a suction channel and at least one of the air channels is connected to the blower side to form an air distributing channel. At least one of the suction channel and the air distributing channel is comprised of two half-shells manufactured by a double deep-drawing process.
