摘要:
A cable insulated with a cross-linked polyethylene layer is described, wherein the cross-linked polyethylene is prepared by cross-linking with 2,5-dimethyl-2-5-di(tert-butylperoxy)hexane or 2,5-dimethyl-2,5-di(tert-butylperoxy)hexyne-3 as a cross-linking agent. Even if voltage is applied at high temperatures, the breakdown voltage of the cable can be maintained at a high level.
摘要:
An electrically insulated cable uses an insulator comprised of an ethylene-vinyl acetate copolymer and an ethylene-.alpha.-olefin copolymer having a density of 0.91 or more. An electrically insulated cable also uses as an insulator a cross-linked composition made of an ethylene-vinyl acetate copolymer and an ethylene-.alpha.-olefin copolymer.
摘要:
An insulating polyolefin laminate paper and a method for producing such a paper in which first and second fiber paper layers are laminated to a polyolefin film layer. The fiber paper layers have an impermeability of 20 to 4000 Gurley-seconds. At least one of the fiber paper layers is mechanically deformed in such a manner that irregularities are produced having a depth of 2 to 50% of the thickness of the fiber paper layer. The mechanical deformation is accomplished prior to lamination. Before lamination, the water content of the fiber paper layers is controlled to be no more than 4%. Preferably, the thickness of the fiber paper layers is at least 30 microns. Furthermore, an electric power supply cable includes an insulating polyolefin laminate paper as an insulating layer.

摘要:
An electrically insulating laminate paper for an electric apparatus to be wound in a wet state on a conductive material and thereafter impregnated with oil, which is characterized by that water drops having a wide particle size distribution are scattered on the surface of the electrically insulating laminate paper comprising an integrated assembly composed of a plastic film and fiber papers bonded to each other to moisten said fiber papers.
摘要:
The present invention is directed to a cooking container for use in heating food in a microwave oven. Specifically, the present invention concerns a cooking utensil capable of heating itself up by microwaves to heat food to such an extent as to be browned but not to be scorched and be stuck to the cooking surface. A fluororesin layer 1 is formed on the top surface of a metal plate 2, and a heat buildup layer 3 adapted to be dielectrically heated by microwaves is formed on the bottom thereof. A covering 4 permeable to microwaves is provided on the outside of the heat buildup layer. The covering is partially formed into legs to support the bottom surface of the plate. A lid capable of reflecting microwaves may be put on the metal plate to shield the food to be cooked against microwaves.

A fluorine resin coated article comprising a metal substrate coated with a composition comprising a fluorine resin containing (a) a polyamideimide resin, a polyimide resin, a polyphenylene sulfide resin, a polyethersulfone resin or a mixture thereof in an amount of at least 0.5 wt % based on the amount of the fluorine resin, and (b) mica in an amount of at least 0.5 wt % based on the amount of the fluorine resin.
摘要:
A redox flow battery is described, mainly including a charge/discharge cell, a cathode electrolyte tank, and an anode electrolyte tank. The inside of the charge/discharge cell is divided into a cathode cell and an anode cell by a diaphragm. A collector plate and a cathode are contained in the cathode cell. An aqueous solution containing a Mn-polyethyleneimine complex is supplied from the cathode electrolyte tank to the cathode through a supply pipe. Thereby, an energy storage battery that has durability sufficient for practical applications in a wide range of fields can be provided.

A positive electrode electrolyte (22) and a negative electrode electrolyte (32) that are used in this energy storage battery have a pH within the range from 2 to 8 (inclusive). An ion exchange membrane, which is obtained by graft-polymerizing styrenesulfonate to a resin film base material that uses an ethylene-vinyl alcohol copolymer as a matrix, is used as a diaphragm (12) of this energy storage battery.
