摘要:
The invention relates to a method for producing a foil or a film (1), comprising the following steps: a) applying at least one material (2) for producing the foil or the film (1) to a moving belt (3), b) at least partially curing and/or partially drying the poured material (2), during which step b) the properties of said material and/or thermal state variables of a defined area around the belt (3) are recorded by means of at least one non-invasive spectroscopic method.

The invention relates to a sealing system (101..108) for a moving metal strip (2), said system comprising an elongate inflatable flexible body (3, 4), a support (5, 6) in which said inflatable body (3, 4) is embedded, and an elongate Teflon body (70..74, 80). Said Teflon body (70..74, 80) is arranged on one of the sides of the inflatable flexible body (3, 4) facing away from the support (5, 6) and comprises a sealing surface (9, 10) facing the metal strip (2) on one of the sides facing away from the inflatable body (3, 4). The invention also relates to an arrangement and a strip casting installation with a metal strip (2) and a sealing system (101..108) of said type.
摘要:
A method of manufacturing a separate and continuous layer being essentially uncured. The method includes applying a powder mix including fibers and a thermosetting binder on a carrier, forming a powder mix layer, wherein the powder mix is connected together such that the powder mix layer is obtained and wherein the powder mix layer is essentially uncured, and releasing the powder mix layer from the carrier. Also, a layer and a method for manufacturing a building panel.
摘要:
A solution (11) containing an organic solvent, a polymer and a plasticizer (TPP, BDP or the like) which is not less than 0.01 wt.% and not more than 50 wt.% of the polymer is cast onto an endless belt (51) to be a casting film (22). Water vapor is condensed from ambient gas on a surface of the casting film (22) passing through a first area (46) to form water drops. The water drops on the casting film (22) passing through a second area (47) are grown and the organic solvent thereof is evaporated. The water drops on the casting film (22) passing through a third area (48) are evaporated. The casting film (22) after passing through the third area (48) is peeled from the endless belt (51) as a flexible porous film (17) by a peel roller (57).
