Abstract
Description
Die Verwendung von Faserstoff auf biologischer Basis ist sehr vielseitig. Sei es zur Herstellung von Isoliermatten oder zur Wärmedämmung durch Ausfüllen von Hohlräumen, speziell beim Hausbau, oder in gepreßter Form als Platten in der Bau- und Möbelindustrie. Für den Einsatz als Baustoff wird zunehmend die bei der Verarbeitung aus gesundheitlichen Gründen nicht unbedenkliche Mineral wolle durch biologische Stoffe ersetzt, da deren Herstellung in der Regel viel weniger energieaufwendig ist und als Grundmaterial fast immer nachwachsende Rohstoffe verwendet werden können. Gegenüber Mineralstoffen besteht aller dings der Nachteil, daß biologische Fasern leicht brennbar sind, so daß aus Gründen der Feuersicherheit Vorkehrungen getroffen werden müssen, um dem Material gewisse feuerhemmende Eigenschaften zu geben. Üblich sind Impräg nierungen mit Salzlösungen oder anderen Stoffen, die sich bei Hitze zersetzen und nicht brennbare, die Flammen erstickende Gase abgeben. Die Zerfaserung der Grundstoffe ist meist ein Naßprozeß. Die Imprägnierung muß ebenfalls naß erfolgen, damit die Imprägniersubstanzen in die Fasern eindringen können. Die dann notwendigen Trocknungen sind sehr energieaufwendig.The use of bio-based fiber is very versatile. Be it for the production of insulating mats or for thermal insulation by filling in Cavities, especially in house construction, or in pressed form as plates in the Construction and furniture industry. For use as a building material, the mineral, which is not harmless due to health reasons wool replaced by biological substances, since their production usually a lot is less energy-intensive and almost always renewable as a base material Raw materials can be used. Everyone exists against minerals dings the disadvantage that biological fibers are easily flammable, so that For fire safety reasons, precautions must be taken to ensure that To give material certain fire retardant properties. Imprints are common with salt solutions or other substances that decompose when heated and give off non-flammable gases that suffocate the flames. The defibration the raw material is usually a wet process. The impregnation must also be wet take place so that the impregnation substances can penetrate into the fibers. The then drying is very energy-intensive.
Es sind Verfahren, z. B. nach DE 44 44 745 oder DE 38 07 017 C2 bekannt, nach denen Holz und andere biologische Stoffe mittels Schneckenpressen durch Reibung unter hohem Druck zerfasert werden. Da diese Fasern die Presse bereits mit niedriger Feuchtigkeit verlassen,ist bei diesem Verfahren der Energieaufwand geringer, als bei den noch üblichen Naßverfahren. Für die Verwendung der Fasern als Isolier- oder Baustoff müßte zur Erlangung einer geforderten Feuerhemmung jedoch noch eine Naßimprägnierung mit dem für die Trocknung erforderlichen Energieaufwand erfolgen.There are procedures such. B. known from DE 44 44 745 or DE 38 07 017 C2, after which wood and other biological materials by means of screw presses be frayed by friction under high pressure. Because these fibers are the Leaving the press with low humidity is the key in this process Energy consumption less than with the still usual wet processes. For the Use of the fibers as an insulating or building material would have to be obtained required fire retardancy but still a wet impregnation with the for the drying required energy expenditure.
Erfindungsgemäß wird das vorgenannte Verfahren der Zerfaserung mittels Schneckenpresse genutzt, um feuerhemmende Substanzen auf trockenem Wege in das Fasergut bereits während der Zerfaserung einzubringen. Umfangreiche Versuche haben bestätigt, daß feuerhemmende, mineralische Substanzen, die mit dem zu zerfasernden Material in die Schneckenpresse eingegeben werden, durch die intensive Reibung und den hohen Druck so in die Struktur der Fasern eingearbeitet werden, daß eine nachträgliche Trennung auf mechanischem Wege nicht mehr möglich ist. Auf diese Art lassen sich auch nichtlösliche, feuerhemmende Substanzen dauerhaft in die Fasern einbringen. Imprägnierverfahren beschränken sich logischerweise auf lösliche Substanzen. Durch die Erfindung kann die Palette der verwendbaren, feuerhemmenden Zusätze wesentlich erweitert werden. Versuche mit CaCO (aus Bauschutt) als Zusatz haben ergeben, daß eine Platte aus gepressten Holzfasern sehr schwer zündbar war, bzw. einen hohen Feuerwiderstand aufwies. Sie verhielt sich selbstlöschend. Das wesentliche der Erfindung zur Herstellung feuerhemmenden, biologischen Faserstoffes gegenüber bisheriger Verfahren ist der weit geringere Energieaufwand und die Möglichkeit, nichtlösliche, feuerhemmende Substanzen einzubringen.According to the invention, the above-mentioned method of defibration is Screw press used to fire retardant substances on dry Introduce paths into the fiber material already during the defibration. Extensive tests have confirmed that fire retardant, mineral Substances with the material to be shredded into the screw press due to the intense friction and the high pressure Structure of the fibers are incorporated that a subsequent separation mechanical way is no longer possible. This way too Introduce non-soluble, fire-retardant substances permanently into the fibers. Impregnation processes are logically limited to soluble substances. Through the invention, the range of fire retardants that can be used Additions are significantly expanded. Try with CaCO (from rubble) as Additions have shown that a board made of pressed wood fibers is very heavy was ignitable or had a high fire resistance. She behaved self-extinguishing. The essence of the invention for producing fire retardant, biological fiber compared to previous methods is the far lower Energy expenditure and the possibility of insoluble, fire-retardant substances bring in.
