Abstract: A composite fabric includes a lining layer and a metallized membrane. The metallized membrane includes a polymer layer having polyurethane and nano/micro metal particles embedded in the polymer layer. The nano/micro metal particles are about 10-50 wt % inclusive of the metallized membrane. The lining layer is connected to the metallized membrane via point contacts.

Abstract: A fabric includes one or more yarns. Each of the one or more yarns include a plurality of filaments. Each of the filaments has an average diameter in a range of 20-50 ?m such that the fabric has an infrared radiation transmittance at a wavelength of 9.5 ?m of at least 37%.

Abstract: A metallized breathable composite textile includes a lining layer and a metallized non-woven sheet disposed on the lining layer. The metallized non-woven sheet includes a base layer containing a polymer and a metal layer deposited on a first surface of the base layer. The lining layer is connected to the metallized non-woven sheet via point contacts.

Abstract: The present invention relates to a ceramic heat exchange plate and an air pre-heater assembled thereby. The air pre-heater comprises a housing, the housing being provided with a lining therein and an access hole thereon. A heat exchange core is arranged inside the lining, and consists of a plurality of ceramic heat exchange plates, side connecting bolt assemblies, corner connecting bolt assemblies and side sealing strips, which are superimposed in a staggered manner; the plurality of ceramic heat exchange plates form a flue gas channel and an air channel which are intersected crisscross, and the flue gas channel and the air channel are not communicated to each other; a flue gas inlet and a flue gas outlet are arranged on a front surface and a rear surface of the housing, respectively; and an air inlet and an air outlet are arranged on a left surface and a right surface of the housing, respectively.
