Abstract: PURPOSE:To make a foam, which is smooth and has favorable thickness precision, continuously and stably manufacturable, by making an endless belt into a metallic net body wherein normal temperature curing or thermocuring a fluororesin or a silicone resin is infiltrated into and applied to the metallic net body. CONSTITUTION:A crosslinking or nonrosslinking foamable polyolefin resin composition sheet 6 is preheated or heat-crosslinked by preheating while it is being conveyed in a preheating sphere 1 by a conveying device provided with an endless belt 4. Then the sheet 6 is foamed continuously by heating in a heating sphere 2. On this occasion, a net body comprised of a base wherein normal temperature curing or thermocuring fluorine resin or silicone resin is infiltrated into and applied to a metallic net body sufficiently is optimum as the conveying endless belt 4 from a viewpoint of fire resistance or heat resistance or durability or peeling properties. The net body is made into the endless belt by joining both ends of the net body of a flowing direction by confronting the both ends with each other.

IPC: C22C1/10
Filed: 1994-06-13
Abstract: PURPOSE:To produce an Al/AlN composite material having a Young's modulus of specified value and to provide a method for producing the same. CONSTITUTION:This Al/AlN composite material is the one in which granular or acicular AlN occuping 40 to 90volume% in a matrix essentially consisting of Al, and having <=1mum diameter is dispersedly held. Since this AIN is extremely fine, it is more integrated with Al in the matrix. Thus, it has high rigidity corresponding to the ratio of the plasticity of the AlN, and its plastic workability and machinability are also good. Moreover, it is small in attackability against the mating material at the time of sliding and is suitable as the sliding material. This Al/AlN composite material can be obtd. by subjecting fine Al to nitriding at the m.p. of the Al or below.
