摘要:
It is the object of the invention to provide an orienting and laminating apparatus of wood chips with a bonding agent applied which can produce continuously a long and thick wood composite material having mechanical strength enough to be used for a structural material, an orienting and laminating method of wood chips with a bonding agent applied, and a production method of a wood composite material. The invention relates to an orienting and laminating apparatus of a wood chip with a bonding agent applied, being an apparatus for orienting and laminating a wood chip with a bonding agent applied, which comprises a supply means of a wood chip with a bonding agent applied, an orientation means of the wood chip with a bonding agent applied, a means of vibrating the orientation means of the wood chip with a bonding agent applied, and a transportation means of a laminated mat of the wood chip with a bonding agent applied laminated, the orientation means of the wood chip with a bonding agent applied comprising a plurality of plates uprightly installed in parallel to be parallel to the transportation direction of the transportation means of the laminated mat, and the orientation means of the wood chip with a bonding agent applied being vibrated slantingly upward from the horizontal direction to the transportation direction of the transportation means of the laminated mat by the means of vibrating the orientation means of the wood chip with a bonding agent applied.
摘要:
A composite material comprising a core layer comprising filler and synthetic resin and containing the filler having a weight 0.7 times or more the product of volume of the core layer and bulk density of the filler; and a surface layer comprising a thermosetting resin reinforced by long fibers extending parallel in a longitudinal direction thereof, the surface layer being laminated on the core layer to cover at least one surface of the core layer with respect to a thickness direction thereof.
摘要:
A pipe molding die of the present invention is capable of rectifying a flow of a molten resin by a resin reservoir and uniformizing the flow of the resin extruded from the die in whichever position in a peripheral direction on a flow path within the die. Consequently, ununiformity in wall thickness of the resin pipe to be molded can be eliminated. The pipe molding die comprises a throttle part as one of components thereof, which includes a core, a shell part fitted to the core and a resin reservoir as a portion of a flow path which is formed between the core and the shell part. A molten, resin as a pipe raw material flows through the flow path. The resin reservoir is provided in at least one of the core and the shell part, and takes a ring-like shape circumscribing a central axis of the pipe molding die with the central axis centered. The resin reservoir assumes a recessed shape in cross-section.
