FREMGANGSMAATE OG ANORDNING FOR FREMSTILLING AV EN TUNGT ANTENNELIG ELLER IKKE BRENNBAR SAMMENSATT PLATE |
摘要 |
A low flammability to non-flammable composite sheet is produced, made of a non-extrudable core of non-combustible particle filler and skins which are bonded to the two sides elastically. In the process, a lower cover band plus an adhesive film are moved in and the core material is distributed over it to form a heap extending over the whole width of the adhesive film; the assembled material is drawn through a tapered gap where its thickness is gauged with/without being compressed; a top adhesive film is applied to the other side, together with the continuously fed top skin; the sandwich formed is further compressed, heated, cooled and finally cut to desired length. The equipment used pref. has a PTFE low-friction table. |
