Abstract: PURPOSE:To make it possible to check the performance of a packed body in a short time, by providing a hollow tube, which contains a coil that detects the amount of swelling change of the container of the packed body provided in a chamber, and providing a displacement converter comprising a core rod positioned in said hollow tube. CONSTITUTION:A detector 14 comprises a hollow tube 16 incorporating a coil, a displacement converter 18, which is positioned in the hollow part and comprises a core rod 17 that is sufficiently smaller than the diameter of the hollow part, and an amplifier 19, which amplifies the impedance of the coil. A projection 20 is provided at the upper part of the core rod 17 so that the rod does not fall from the hollow tube 16. With the swelling of a container, the core rod 17 is mounted on the container and lifted. Then the impedance of the coil in the hollow tube 16 is changed. The amount of change is detected by the displacement converter 18. The result is further converted as the amount of movement by the amplifier 19. The defective product is found when the amount of swelling change exceeds the specified value. Thus the performance of the packed product can be checked in a short time.

Abstract: PURPOSE:To make it possible to check the characteristic of a packed body in a short time, by placing the packed body in a chamber, reducing the pressure in the chamber, and detecting the fact that the pressure in the chamber becomes lower than the internal pressure reduction degree of the packed body by a detector. CONSTITUTION:A pressure reduction checking device of a packed body comprises the following parts: a chamber 9; a pressure reducer 10; a detector 11 with a buzzer, which detects the displacement of the packed body that is arranged in the chamber 9; and a display part 12, which displays the pressure reduction degree in the chamber. The packed body 1 is placed in the chamber 9, and the pressure in the chamber 9 is reduced by the pressure reducer 10. Since the internal pressure reduction degree in the packed body 1 is maintained, the packed body 1 swells largely at an instant the pressure in the chamber 9 becomes lower than said internal pressure reduction degree. When said displacement exceeds 2-4mm., the buzzer is sounded. The pressure reduction degree at at this time is read on the display part 12. Thus the check of the packed body can be performed in a short time.

Abstract: PROBLEM TO BE SOLVED: To provide a heat-insulating box body the strength of which does not become an issue even when numerous vacuum insulating materials are used and which exhibits a high insulation efficiency, to provide a method of manufacturing raw material by which the recycling of materials used in the box body can be made easier by improving the recycling rates of the materials, and to provide a refrigerator. SOLUTION: The heat insulating box body exhibiting superior insulating performance and having high durability is obtained by using highly rigid low- density hard urethane foam manufactured by using a tolylene diisocyanate composition and water as a foaming agent together with a vacuum insulating material. Consequently, the recycling of the materials used in the box body by chemical recycling can be industrialized easily.

Abstract: PURPOSE: To obtain the foamed heat-insulating material excellent in heat insulation, environmental compatibility, etc., and useful for refrigerators, freezers, etc., by mixing a foaming polyurethane raw material composition with a specific carbon dioxide-adsorbing agent with stirring. CONSTITUTION: This foamed heat-insulating material is produced by mixing (A) a raw material composition comprising an organic polyisocyanate, a polyol, a catalyst, a foam stabilizer and water as a foaming agent with (B) a carbon dioxide-adsorbing agent coated with a plastic such as PVA. The component B is preferably potassium hydroxide-adsorbed activated carbon coated with PVA. The foamed heat-insulating material is obtained e.g. by preliminarily mixing the raw materials of the component A, and subsequently mixing the component A with the component B to produce the foamed product.

Abstract: PURPOSE:To obtain the title structure excellent in heat-insulating properties, flame retardancy and noncorrosiveness by packing an expanded heat-insulating material prepared by using a hydrocarbon foaming agent and containing a hydroxy organo-phosphorus compound into a heat-insulating structure having a metal pipe in its inside. CONSTITUTION:A starting material containing an organic polyisocyanate, a polyol and additives including a catalyst, a foam stabilizer and a halogen-free organophosphorus compound having a molecular weight of 150 or above and having a functional hydroxy group is mixed and expanded with a blowing agent of a hydrocarbon such as pentane or cyclopentane to obtain an expanded heat-insulating material. This material is poured into the space confined by a plastic facing material 2 such as ABS and an iron sheet 3 and having a copper pipe through which a refrigerant is circulated and molded to obtain a heat- insulating structure 1 packed with an expanded heat-insulating material 4. This material has flame retardancy equivalent to that of CFC11 and does not suffer from the corrosion of the metal pipe by freed phosphorus nor its migration to the plastic facing material.
