Section for pressure release surface esp. for explosive fall-out - comprises inner and outer sides and connection surface, sides have metallic layers covered with electro-static layer, connection surface includes elastic sealing

摘要

The section has opposed inner and outer sides (5,6) and at least one connection surface (7). The section (s1,s2) is formed from a hard foam body. The section has at least one metallic layer on both the inner and outer sides. Between the inner side metal layer and the hard foam body another layer is provided which is harder than the foam body. There is a layer of varnish over the metallic layers with an electro static top-charge under the metallic layers. The connection surface includes a groove (8) and a spring (9), there is an elastic strip (10) sealing running along near the groove. The metallic layers usually consist of aluminium foil.
