摘要:
A wood-like molding comprising a polymer (A) composed mainly of a polymethacrylic ester, an inorganic filler (B), and cellulosic microparticles (C) [preferably cellulosic microparticles (D)] each containing an inorganic pigment biting into the surface thereof; and a process for preparing a wood-like molding which comprises molding a starting composition by cast molding. The wood-like resin molding is free from fuzzing, exhibits a homogeneous wood-like pattern with satisfactory wood texture, is free from changes in appearance, such as uneven color, for a long period of time, and does not give any burned mark at the time of molding.
摘要:
A process is provided for curing a high internal phase emulsion to form a porous crosslinked polymeric material, comprising the steps of: forming a high internal phase emulsion having at least one curable phase; providing a continuous strip of polymeric film wherein the polymeric film is incompatible with each of the phase of emulsion; placing at least a portion of the emulsion continuously on the polymer film; closing the polymeric film around the emulsion; spiraling the emulsion in the polymeric film onto a spool, wherein the spool rotates about an essentially vertical axis for storage of the emulsion during curing; and curing the emulsion within the polymeric film on the spool. Apparatuses to perform this process are also disclosed.

摘要:
Disclosed is a method of producing a non-woven web of fibrous or particulate material comprising: formation of a foam slurry; deposition of that slurry onto a foraminous element having a three-dimensional mold; and formation of a web having a three-dimensional shape that is not substantially planar by removal of foam from the slurry through the foraminous element and drying the web. An apparatus therefor is also disclosed. The method may be used in production a variety of products, including automotive pleated fluid and air filters, pleated heating and/or air conditioning (HVAC) filters, shaped breathing mask filters and bacterial filters, laminated cleaning products with super-absorbent middle layers, such as a mop wipe shape to fit a cleaning mop head, and other products.
摘要:
A device for the production of slabs of wax or other thermoplastic material is provided with two endless conveyor belts (1, 2) placed opposite each other and one above the other between which the wax is fed, with side guide (17) running along with and between the parts of the conveyor belts facing each other and with cooling means (9, 10) for cooling the wax. The device contains side guide belts (17) with two flat parallel surfaces, each of which sealingly engages with the opposite surface of the corresponding conveyor belt part. The device is suitable for processing wax with a sticky character due to the horizontal position of the belts and the relatively large sealing areas between the belts and the side guides.
摘要:
A method of making a magnetically loaded pre-impregnated tape uses a drum (1) that is heated and which is associated with a heated bath (2) containing a thermo-plastic resin solution. A fibre tape material (4) is fed onto the drum (1) and, just prior to the fibre tape material meeting the periphery of the drum, the fibre tape material (4) is impregnated with an isotropic magnetic particle material (6) to form the pre-impregnated tape (8). The pre-impregnated tape may be fed to a heating station where it is bonded with a thermoplastic resin impregnated fibre tow to produce a magnetically loaded composite tape.
