摘要:
A method of producing pulp moldings having a paper-making process comprising the steps of assembling split mold halves (11, 12) having suction passageways (14) to form a paper-making mold (10), feeding pulp slurry of predetermined set feed concentration into the cavity (13) in the paper-making mold (10), and sucking the pulp slurry through the suction passageways (14) to form a pulp layer (15) on the inner surface of the paper-making mold (10), wherein the concentration of the pulp slurry in the cavity (13) in the initial and/or final period of formation of the pulp layer (15) in the paper-making process is lower than the above-mentioned set feed concentration of the pulp slurry.
摘要:
A shape memory rubber molded article (1) obtained from a mixture containing a rubber and a crystalline non-polymeric compound. The rubber in the molded article is crosslinked. A deformed state of the shape memory rubber molded article (1) is fixed by crystallizing the non-polymeric compound, and the fixed deformed state is released by melting the non-polymeric compound. The non-polymeric compound is preferably a wax. The shape memory rubber molded article (1) preferably contains a crosslinking agent. In the molded article (1), the rubber and the non-polymeric compound are preferably in finely divided separate phases.
摘要:
A process of producing a wax composition mainly comprising a wax, including the step of mixing the wax and a component to be mixed with the wax by applying an external force at a temperature lower than the melting completion temperature of the wax.
摘要:
A biodegradable wax composition containing a wax as a main component and also containing a biodegradable polymer and a filler and having a moisture permeability of 3 g·mm/m2·24 hr or less at 40° C. and 90% RH. The wax is preferably present in an amount of 65 to 95% by weight. The biodegradable polymer preferably has a weight average molecular weight of 200,000 or higher. The polymer is preferably polyisoprene or natural rubber and is preferably present in an amount of 5 to 35% by weight.
摘要:
A heat-insulating container having a first fiber layer (111) with a prescribed density and a second fiber layer (112) which is formed inside the first fiber layer (111) and has a lower density than the first fiber layer (111). The first fiber layer (111) is 0.2 to 1 mm thick, and the second fiber layer (112) is 0.4 to 3 mm thick, with the total thickness of the first fiber layer (111) and the second fiber layer (112) being 0.6 to 4 mm.
摘要:
A biodegradable film having a biodegradable moisture barrier layer between two biodegradable resin layers. The moisture barrier layer is preferably made mainly of a biodegradable wax. The moisture barrier layer preferably contains the biodegradable wax and a biodegradable, heat-resistant polymer. The polymer is preferably natural rubber or polyisoprene.
摘要:
A plastic molding produced by molding a resin composition comprising 98 to 50 parts by weight of a thermoplastic polyester resin (A) and 2 to 50 parts by weight of a resin (B) incompatible with the thermoplastic polyester resin (A), the resin (B) being dispersed in the resin (A), wherein the resin (B) has in a layer that is situated at an arbitrary depth from the outer surface of the plastic molding a substantially rodlike form satisfying the requirement represented by the following formulae (1) and (2) and is oriented in parallel to the outer surface of the plastic molding and in the direction of flow of the resin composition in molding:1.ltoreq.P/Q.ltoreq.10 (1)(P+Q)/L.ltoreq.0.5 (2)wherein L, P and Q represent the size of the particle of said resin (B) and respectively have the following values:L: the average length (.mu.m) in the direction of stretching of the particle;P: the average major axis (.mu.m) in the case where a section perpendicular to the direction of stretching of the particle is approximated to be elliptical; andQ: the average minor axis (.mu.m) in the case where the section perpendicular to the direction of stretching of the particle is approximated to be elliptical.
