schengelagert. Dabei wird jede Materialsorte vorzugsweise
in 3 Stufen getrennt aufgeschlossen: Einerseits im Schred
der zu ca. 20-50 cm² großen Stücken, andererseits in der
Hammermühle zu ca. 4-6 mm² großen Stücken und im Zerfase
rer zu Fasern vermahlen.
The following production process is preferred for the production of the insulation boards according to the invention:
Each of the materials used in the paper, kraft paper, newsprint, cellulose, cardboard, wallpaper, egg carton boxes and egg packaging boxes are separated into finished fibers and stored in a fiber bunker. Each type of material is preferably broken down separately into 3 stages: on the one hand in the shredder of the pieces of approx. 20-50 cm², on the other hand in the hammer mill to approx. 4-6 mm² pieces and in the shredder to fibers.
Von entscheidender Bedeutung ist dabei, daß das Material nach jeder Stufe entstaubt wird, und alle Partikel kleiner 63 µm (der Staub) abgesondert werden. Dies ist besonders wichtig, da das Verfahren sonst nicht befriedigend funk tioniert.It is crucial that the material dust is removed after each stage, and all particles smaller 63 µm (the dust) can be separated. This is special important, otherwise the procedure will not work satisfactorily worked.
Sofern die Stoffe Heu, Laub oder Stroh Verwendung finden, werden diese im Zerfaserer entsprechend zerkleinert, ent staubt und ebenfalls zwischengelagert.If hay, leaves or straw are used, these are crushed accordingly in the fiberizer dust and also temporarily stored.
Sofern Ausgangsstoffe wie Jute, Sisal, Leinfasern, Hanf, Schilf, Flachs, Rohbaumwolle, Kokosfasern oder Heu Verwen dung finden, werden diese Fasern entsprechend aufgelockert. Diese Materialien können in jeder Kombination vermischt werden.If raw materials such as jute, sisal, flax fiber, hemp, Use reeds, flax, raw cotton, coconut fibers or hay finding these fibers are loosened accordingly. These materials can be mixed in any combination will.
Je nach Rezeptur werden aus den Faserbunkern die entspre chenden Materialien über Bandenwaagen zum Mischer dosiert und dabei nochmals entstaubt.Depending on the recipe, the fiber bunkers are used dosing materials on belt scales to the mixer and dusted again.
Im Trockenmischer wird aus den einzelnen Faserkomponenten ein homogenes Gemisch hergestellt.The individual fiber components are made in a dry mixer made a homogeneous mixture.
Auf dem Weg zum nächsten Mischer wird das Material mit Borax imprägniert, indem das Borax als 40-60%ige wäßrige Lösung mit Düsen aufgesprüht wird.On the way to the next mixer, the material comes along Borax impregnated by the borax as 40-60% aqueous Solution is sprayed with nozzles.
Sofern weitere Bindemittel (Tallharz, Balsamharz oder Lig ninsulfonat sowie Borsäure oder Aluminiumsulfat) Verwendung finden, werden diese in entsprechenden Mengen pneumatisch in eine Feinmühle dosiert, dort gemahlen und kurz vor dem zweiten Mischer, also nach der Imprägnierung mit Borax zu gegeben.If other binders (tall resin, balsam resin or lig ninsulfonate and boric acid or aluminum sulfate) use find, they are pneumatic in appropriate quantities dosed in a fine mill, ground there and shortly before second mixer, i.e. after impregnation with borax given.
Nach diesem Schritt und direkt vor dem zweiten Mischer wird das Magnesiumchlorid oder Calciumchlorid als 20-50%ige wäßrige Lösung zugegeben. After this step and right before the second mixer is made the magnesium chloride or calcium chloride as 20-50% aqueous solution added.
Die gesamten Komponenten werden nun dem Mischer zugeführt, und dort wird dann ein homogenes Gemisch hergestellt.All the components are now fed to the mixer, and a homogeneous mixture is then produced there.
Auf einer Streumaschine mit einer gesteuerten Rückstreif walze wird eine gleichmäßige Schicht aus dem Dämmaterial gebildet, die vorgepreßt wird.On a spreader with a controlled rear streak roller becomes an even layer of insulation material formed, which is pre-pressed.
Das Material wandert dann in den Dämpfkanal, wo die Binde mittel durch eine Zugabe von Wasserdampf mit einer Tempera tur von etwa 110° Celsius aktiviert werden.The material then migrates into the damping channel, where the bandage medium by adding water vapor with a tempera be activated from about 110 ° Celsius.
Die Masse wird nun durch ein Preßband auf das gewünschte Sollmaß gedrückt.The mass is then brought to the desired level using a press belt Target dimension pressed.
Die Platten werden dann im Trockenkanal bei einer Tempera tur von etwa 40° Celsius getrocknet.The plates are then in the drying tunnel at a tempera dried from about 40 ° Celsius.
Bei der Endverarbeitung kann der kontinuierliche Platten strang dann zu den einzelnen Plattenformaten geschnitten, verpackt und palettiert werden.In the finishing process, the continuous plates then cut to the individual plate formats, packed and palletized.
Wenn statt der Herstellung von Dämmplatten aus dem Dämma terial die Verwendung des Dämmaterials als loses Isolier material beabsichtigt ist, wird das Material nach Verlassen des zweiten Mischers im losen Zustand mit Wasserdampf bei einer Temperatur von etwa 110° Celsius beaufschlagt, um die Bindemittel zu aktivieren. Das lose Material wird dann im Trockenkanal bei einer Temperatur von ca. 40° Celsius ge trocknet.If instead of producing insulation boards from insulation material the use of the insulation material as loose insulation material is intended, the material will be left after of the second mixer in the loose state with water vapor a temperature of about 110 ° Celsius To activate binders. The loose material is then in the Drying tunnel at a temperature of approx. 40 ° Celsius dries.
Gegenüber den bisherigen Herstellungsverfahren für Dämma terialien hat dieses Verfahren noch den Vorteil des gerin geren Energieverbrauchs. Gemäß dem Stand der Technik ist nämlich bisher im Dämpfkanal eine Dampftemperatur von etwa 1500 Celsius erforderlich. Demgegenüber wird jetzt nur eine Dampftemperatur von 110° Celsius benötigt. Ebenfalls kann die Trocknung erfindungsgemäß bei wesentlich geringerer Temperatur erfolgen, nämlich bei 40° Celsius statt bisher 80-100° Celsius.Compared to the previous manufacturing process for insulation This method still has the advantage of materials lower energy consumption. According to the state of the art namely so far a steam temperature of about in the steam duct 1500 Celsius required. In contrast, now only one Steam temperature of 110 ° Celsius is required. Can also the drying according to the invention with much less Temperature take place, namely at 40 ° Celsius instead of previously 80-100 ° Celsius.
