Abstract: PURPOSE:To reduce hazards of an explosion and fire, by a method wherein a chamber filling and foaming raw materials and a chamber solidifying them after the foaming are separated from each other and a suction filter sucking a hydrocarbon is installed into a blower route of the solidifying chamber. CONSTITUTION:A suction filter 22 comprised of a conductive fiber material and an active carbon suction material is installed into a circulation air path 21 and the suction filter 22 is earthed. In the fourth process 6, both stock solutions through a hydrocarbon stock solution storage tank 23 and polyol stock solution storage tank 24 of pentane or cyclopentane into which nitrogen gas is enclosed are mixed 25 up with each other. The stock solutions are supplied to a casting machine 28 through a piping path arriving at the casting machine 28 by storing in a work tank 26 and a piping path storing in a work tank 30 from an isocyanate stock solution storage tank 29 and arriving at the casting machine 28 by a pump 31. The final mixing is performed by the casting machine 28 and filled up into a space between a pair of walls. Hereby, density of the hydrocarbon in a cure chamber 20 can be lowered.

Abstract: PURPOSE:To produce safely without having hazards of an explosion and fire in a foaming process, by providing a communicating port for setting an evaporated hydrocarbon streamed out through a heat insulation box body free out of a jig is provided in the jig. CONSTITUTION:A foaming jig is constituted of an outer jig 5 and inner jig 6. The outer jig 5 makes a circumferential frame 5a covering the circumference of an outer box 8 and a top frame 5b movable by a hinge. A vent hole 10 comprised of a small hole is formed in the rear 8a of the outer box 8 also and a communication port 7 and the vent hole 10 become coincident with each other. An evaporated hydrocarbon streamed through the vent hole 10 provided in the outer box 8 can be set free to the outside through the communication port 7. Consequently, even if a foamed heat insulation material 11 for which such a substance that has explosive properties is used as a foaming agent, dwelling of the evaporated hydrocarbon between the outer jig 5 and inner jig 6 is eliminated.

Abstract: PURPOSE:To eliminate the danger of explosion or a fire in a urethane foaming process and thereby to enable execution of safe production by providing a process of eliminating static electricity of a jig for foaming, an inner jig, a workpiece, etc., before injection of urethane in urethane foaming equipment using hydrocarbon as a foaming agent. CONSTITUTION:A process of eliminating static electricity is executed by a foaming jig of a heat-insulating box which is formed by a bottom jig 9 a part of which is grounded, by an inner jig 10 being in contact with the bottom jig 9 and by a top jig 11 of synthetic resin and lateral jigs 12 of synthetic resin which surround the inner jig 10. A static electricity eliminator 13 of a voltage impression type generates ions 14 and thereby eliminates electric charges generated in the inner jig 10, the top jig 11 and the lateral jigs 12 made of the synthetic resin and being nonconductors. Even when an explosive substance, hydrocarbon such as pentane or cyclopentane, is used as a foaming agent in a posterior process, as the result, the static electricity is hardly generated in the advance of foaming and the danger that the foaming agent explodes in the course of a heat-insulative foaming operation and destructs the surroundings is eliminated.

Abstract: PURPOSE:To prevent a hydrocarbon of a foaming agent from being exploded, since even if static electricity which is apt to be generated by progressing the foaming of a foamed heat insulation material is led outside, by a method wherein a wall surface of an inner box comprised of a synthetic resin on the foamed heat insulation material side is made into the same electric potential as that of an outer box by applying a conductive coating to the wall surface. CONSTITUTION:A heat insulation box body 1 of a refrigerator is formed of a metallic outer box 2, an inner box 3 made of a synthetic resin and a foamed heat insulation material 4 wherein a hydrocarbon filled into a space between both the boxes 2, 3 is taken as a foaming agent. In the outer box 2, a double flange 5 is formed on a front edge of an opening, in which an outward flange 6 formed on the front edge of the opening of the inner box 3 is inserted. A conductive coating 7 is applied to the surface of a foamed heat insulation material side of the inner box 3. The conductive coating 7 is positioned at the flange also, joined electrically to the double flange 5 of the outer box 2 and formed into the same electric potential as that of the outer box 2. Hereby, it becomes earthable easily through the outer box 2. Such a hazard that the circumference is destroyed by an explosion of a foaming agent during a foaming operation of a heat insulation material is eliminated.
