摘要:
The invention relates to an insulation element (1) for electrical insulation of an electro-technical component in the high-voltage range. The insulation element (1) has a first layer (2) which includes cellulose, and a second layer (3) which includes cellulose. Arranged between the first layer (2) and the second layer (3) is an intermediate layer (5) which includes micro-scale and/or nano-scale cellulose.
摘要:
An object of the present invention is to provide a fiber aggregate for a molded article having satisfactory appearance that can provide a molded article excellent in stiffness and strength against bending, further excellent in impact resistance and appearance. The object of the present invention is also to provide a pre-sheet and a molded article that are obtained from the fiber aggregate for the molded article. The fiber aggregate for molding according to the present invention includes the fiber component and the thermal fusion bonding resin component, in which the fiber component contains a pulp fiber and a polypropylene fiber; the thermal fusion bonding resin component contains at least one selected from the group consisting of polyethylene and acid-modified polyethylene; a content of the thermal fusion bonding resin component in the fiber aggregate is 3% by mass or more and 18% by mass or less; and when T represents a tensile strength of the fiber aggregate in a first direction, and Y represents a tensile strength of the fiber aggregate in a second direction perpendicular to the first direction, a T/Y ratio is 0.5 or larger and 1.5 or smaller.
摘要:
Insulators and polymer-coated insulators are provided. The insulators can include thermally-insulating nanoparticles and a binder configured to volatilize at a volatilization temperature. Insulators can also include an inorganic thermally-insulating material forming a porous structure. The porous structure can be configured to reduce the mean free path of gases in the insulator as compared to gases outside the porous structure. Polymer-coated insulators including an inorganic thermally-insulating material and a polymer coating disposed on the surface of the inorganic thermally-insulating material are also provided. Insulators can also include thermally-insulating nanoparticles and an opacifier. The opacifier can include a carbonaceous material coated with a refractory material that inhibits oxidation of the carbonaceous material at a carbon oxidation temperature. The insulators or polymer-coated insulators can be disposed between battery cells or battery cell blocks in an apparatus.
