Width 5mm 1'X with spring for film tension
They are opposed with a 2 mm peripheral spacer and fixed with adhesive. When installing, add 100% gold to the surrounding spacer in advance.
0 person vacuum 7? A 100 μm polyethylene terephthalate film that has been marked by the Ui method is bonded under tension using a fixing tool, and then placed in a heated electric furnace kept at 120"C in a fixed state for approx. 1
The film was heated for a period of time to cause heat shrinkage so that the film was substantially parallel to the glass plate and had no visible non-uniformity. Next, an opening for injecting an adhesive to fill the glass void is provided in a part of the peripheral spacer, and an acrylic adhesive Naphtran (manufactured by BMG Corporation) is injected until the void inside the glass is completely eliminated. Thereafter, it was cured at room temperature to obtain a window plate for electromagnetic shielding, which is an example of the present invention.

わめて大きいと云わざるを得ないのである。Table 1: Industrial Applicability] According to the present invention, an electromagnetic shielding film is inserted into the center of two sheets of non-conductive material such as glass or plastic arranged in parallel, and By fixing it to a spacer and utilizing the heat shrinkability of the film, wrinkles and corrugations of the film can be minimized, and furthermore,
This is easily obtained by injecting a highly fluid room-temperature curing adhesive into a small gap between a pair of non-conductive materials 1 and a film and curing it, resulting in high productivity and good-looking soundproofing. It is possible to provide a window plate with high magnetic wave shielding properties, and it cannot be said that its industrial applicability is extremely large.
