Definitions
- the invention relates to a wood fiber board for roof and wall construction with the features of the preamble of independent claim 1 and to a method for producing such a wood fiber board with the features of the preamble of independent claim 4.
- a wood fiber board with the features of the preamble of independent claim 1 is z. B. from the WO 94/23914 known. There is also a method for their preparation with the features of the preamble of independent claim 4 is described.
- the known wood fiber board is offered by the applicant as a diffusion-open wall and ceiling plate.
- the wood fiber board can be applied as a second water-bearing layer directly on the rafters.
- the roof is covered, and the windows and doors are installed.
- the screed and the interior plaster are introduced into the new building.
- the heating is usually put into operation to dry out the new building.
- Borates are used as flame retardants for lignocellulosic building materials, such as insulating fillings and are considered environmentally harmless.
- the concentration of borates used as flame retardants is typically 8% atro fibers. Borates are also known to have a fungicidal action which is sufficient for effective mold protection from a concentration of about 1% of atro fibers. Since the binder content of atro fibers in wood fiberboards, which are the subject of the present invention, is typically of the order of magnitude required for mold protection by borates, and even less than the amount in which borates are used as flame retardants, a process must be used for the production of a wood fiber board with such a mold or flame retardant on the presence of relatively large amounts of borate are specially tuned. This is in addition to the cost of borates additional costs associated.
- WO-A-20061065259 From the post-published WO-A-20061065259 are known building materials with bioresistant properties. These building materials, which may be wood fiberboards, have a biocide which, among many other substances, may also be calcium borate, zinc borate, barium bismuth and mixtures thereof. However, particularly preferred is the use of copper oxinate as a biocide, to which the description of the WO-A-2006/065259 concentrated.
- the copper oxinate is sprayed onto a surface of a fiberboard in a mixture with water and solidifying additives such as latex strengthening agent.
- the concentration of the copper oxinate is 0.01 to 2% by weight of the liquid mixture, which is applied in an area concentration of 2 to 12 g of liquid per square foot. This corresponds to 0.0043 to 5.2 g of copper oxinate / m 2 . Corresponding information is not available on any other of the biocides which have a different biotoxicity.
- the US-B-6416789 describes the use of boron-containing fungicides, such as zinc borate, calcium borate and sodium borate, designated as such at typical use levels as providing poor mold protection, in combination with an organo-iodine compound and an amine oxide compound as a mold protection for wood fiberboards.
- This mixture can be sprayed on to treat the wood fiber boards.
- concentration in which the boron-containing compounds should be present in addition to the other fungicidal substances in the wood fiber boards 0.1-5% are given based on the weight of the wood fiber boards.
- boric acid From the GB-A-829407 is a one-sided treatment of fiberboard with boric acid known to improve their sound-absorbing properties.
- the boric acid should be used in an area concentration of 4-15 grams per square foot, which corresponds to 43-161 grams per square meter.
- the invention has for its object to provide a wood fiber board for roof and wall construction and a method for their preparation, by the sufficient mold protection with minimal effort, ie in particular with minimal entry of Foreign material into the fiberboard and minimal increase in the cost of producing the fiberboard is achieved.
- the new fiberboard has borates in an area concentration of not less than one gram and not more than 25 grams per square meter. These borates are in the area of the shoring inward, ie concentrated in the roof down to align main side of the wood fiber board. For this reason, the amount of borates in the new fiberboard is also defined as the area concentration and not the volume concentration. With a board thickness of the wood fiber board of 16 mm and a bulk density of the wood fiber board of 565 kg / m 3 , the amount of borates present in the new wood board is less than 0.3% of atro fibers. This value would be completely inadequate for effective mold protection in the volume of fiberboard.
- borate concentration is still sufficient to provide good mold protection. Due to the relatively small total amount of borates, the cost of the new wood fiber board compared to a wood fiber board without mold protection are only slightly increased. It is also not necessary to significantly change the process for their preparation. Ultimately, the entry of foreign matter in the wood fiber board is so low that it does not lose their safety from an environmental point of view, especially since borates are to be regarded as fundamentally less critical in this respect.
- the borates are not only on the main side of the wood fiber board to be aligned inside, but both as well as below the surface of the fiberboard on this main page.
- abrasion of the borates is prevented in their handling, including the stacking of wood fiber boards, and also a rapid washing away of the borates under the influence of moisture.
- the risk that the borates are washed off and washed off, for example, by water condensing on the inside of the wood fiber boards, so that they become ineffective is relatively low because the water solubility of borates is strongly temperature-dependent and even at a reduced temperature of 10 ° C. only at about 100 g / l.
- weather influences on the construction site are therefore not associated with the immediate danger that the borates are lost from their area at the inboard facing main side of the wood fiber boards.
- the corresponding main page may be provided with a mark.
- the one-sided addition of borates in the area to a main side of the wood fiber boards is usually not visible. He can, however, by dyes that z. B. the borates are struck directly, made visible. It is also possible to provide the main pages with printed instructions on their orientation to be made. In the simplest case, the new wood fiber boards are stacked on pallets, as it corresponds to their subsequent alignment, d. H. e.g. with their roof sides down to be aligned main pages down. If this orientation of the wood fiberboards is maintained, no marking on the fiberboard itself is necessary.
- the borates are applied in an area concentration of not less than 1 gram and not more than 25 grams per square meter to a main side of the fiber cake pressed to the wood fiber board or the wood fiber board itself the lining to be aligned inside the main side of the wood fiber plate forms.
- the borates can thus be applied to the already substantially fiberboard before the hot pressing on the fiber cake or after hot pressing.
- the application to the fiber cake is the application to the fiber cake, because in this way a stronger involvement in the adjacent to the later inner main page volume of wood fiber board is done.
- borates may be applied to the fiber cake or fiberboard by sprinkling the fiber cake with dry borates or by rolling or spraying the borates. It is favorable if the borates are present during application in the form of a solution, in particular a solution in water. The evaporating water leaves the borates back and does not lead to contamination of the fiberboard.
- the borates are sprayed onto the fiber cake from above in the form of a solution in water, whereby the water applied with the borates is vaporized during the hot pressing of the fibreboards.
- the remaining borates are then incorporated into the volume of the fiberboard near their lower main page, which reliably prevents unwanted washing out by condensation water or the handling of the wood fiber boards or direct weather influences on the wood fiber boards on a construction site.
- the fibrous board be turned after hot pressing and further processed downwardly with its main side containing the borates, i. H. packed and transported, for example.
- the wood fiber board is stacked with other identical wood fiber boards to form a stack in which the main side of the wood fiber boards to be aligned downwards in the roof construction lies at the bottom. This alone protects the borates from the effects of the weather, for example rain on the pile.
- Another or additional indication of the meaningful orientation of the new wood fiber boards in the construction can be given in the context of their production, that together with the borates, a dye is applied to the one main side of the fiber cake or the wood fiber board, which is to be aligned inside the main side the fiberboard forms.
- the previously stated upper limit for the boron surface concentration of not more than 25 g / m 2 which corresponds to less than 0.3% of atro fibers for a 16 mm thick fibreboard of 565 kg / m 3 gross density, need not be exhausted in order to obtain the provide desired mold protection. This is also achieved with a maximum of 20 g / m 2 for very long periods. Even with 8 to 10 g / m 2 can not with a mold protection at one insulated roof of about half a year can be expected. A usually completely sufficient mold protection of at least two months is reliably achieved with about 6, ie 5 to 7 g / m 2 . An underlying surface concentration of the borates can only cause a shortened protection. An area concentration of less than 2 g / m 2 is already essentially ineffective.
- Suitable borates for use in the novel wood fiber board and their production are, in particular, inorganic borates, in particular alkali metal, alkaline earth metal and / or ammonium borates. These borates are on the one hand cost-effective and on the other hand largely harmless from an environmental point of view. From an environmental point of view, this means both the influence of the wood fiber board on the living climate in an adjacent living space and the recyclability of the wood fiber board.
- wood fiber board 1 is provided in addition to the wall construction specifically for use in the roof construction and shown here with a roof pitch.
- the wood fiber board 1 has a typical thickness of 12 to 20 mm and a typical average apparent density of 530 to 600 kg / m 3 .
- the wood fiber board 1 forms a vapor-permeable layer in the roof construction, so that water vapor can pass through it.
- inwardly directed main side 2 of the wood fiber board 1 these can not immediately on the opposite, upwardly, outwardly directed main page 3 diffuse.
- inorganic borates 4 are provided, which has the wood fiber board 1 at and behind its surface 5 at its lower main page 2. The borates 4 are thus on the surface 5, but also within the adjoining volume of the wood fiber board 1 before, but not on the upper main page 3, where no mold protection is needed.
- the concentration of the borates 4 on the lower main side 2 makes it possible to give the wood fiber board 1 sufficient mold protection with respect to atro fibers of the wood fiber board 1 very small amounts of borates 4.
- concentration of about 6 g / m 2 of borates 4 which is less atro fibers 0.1% means sufficient mold protection for a period of at least 3 months.
- Fig. 2 outlined the preparation of the new wood fiber board 1 according to Fig. 1 ,
- a solution 7 of the borates 4 is sprayed from above in water before the fiber cake 6 is pressed in a hot press 8 under the action of elevated pressure and elevated temperature to the wood fiber board 1.
- the main page 2 where the borates 4 are present oriented upwards.
- the wood fiber board 1 is then turned through 180 °, so that the main side 2 with the borates 4 then points downwards.
- the solution 7 could be sprayed even after the hot press 8 on the still warm wood fiber plate 1, before it is turned in the inverter 9.
- Fig. 3 outlines a stack 10 of several wood fiber boards 1 on a base 11.
- the borates 4 are largely protected in the wood fiber boards 1 within the stack 10 from the weather.
- the embedding is also contrary to a simple leaching of borates 4 with rainwater or on the main side 2 condensing water. It is also advantageous that the water solubility of the borates is only slight at reduced temperatures.
- the user of the wood fiber boards 1 can also be pointed out by the necessary orientation of the wood fiber boards 1 in the roof, which together with the borates 4 a dye is applied, which distinguishes the main side 2 of the wood fiber boards from their borate-free main page 3.

Description
Die Erfindung bezieht sich auf eine Holzfaserplatte für den Dach- und Wandbau mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 1 sowie auf ein Verfahren zur Herstellung einer solchen Holzfaserplatte mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 4.The invention relates to a wood fiber board for roof and wall construction with the features of the preamble of
Eine Holzfaserplatte mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 1 ist z. B. aus der
Hierdurch kommt es zu einer Kondensation von Feuchtigkeit an den Holzfaserplatten und den Sparren. In der Folge kann es innerhalb weniger Wochen zu Schimmelbildung kommen. Sobald die Innendämmung des Dachs angebracht ist, tritt dieses Problem nicht mehr auf. Bekannt ist das Problem der Schimmelbildung an Holzfaserplatten aber auch bei mangelhaft abgedichteten Dächern und unbelüfteten Kaltböden. Es kann ebenso bei Wänden und auch bei hinterlüfteten Fassaden auftreten bei denen Holzfaserplatten ebenfall eingesetzt werden.This leads to a condensation of moisture on the wood fiber boards and the rafters. As a result, mold can form within a few weeks. Once the inner insulation of the roof is installed, this problem no longer occurs. Known is the problem of mold growth on wood fiber boards but also poorly sealed roofs and unventilated cold floors. It can also occur in walls and also in ventilated facades where wood fiber boards are also used.
Zur Vermeidung von Schimmelbildung bei Holzwerkstoffplatten, zu denen Holzfaserplatten zählen, ist grundsätzlich der Einsatz verschiedener Substanzen mit fungizider Wirkung bekannt. Viele dieser Substanzen verbieten sich jedoch für die Verwendung bei Holzfaserplatten für den Dachbau, weil diese dem Innenbereich eines Hauses, d. h. dem Wohnraum, zuzurechnen sind, und Fungizide die Gesundheit von Menschen beeinträchtigen können. Zudem ist die von der Anmelderin vertriebene diffusionsoffene Wand- und Deckenplatte als umweltfreundlich zertifiziert, und diese Zertifizierung steht dem Einsatz herkömmlicher Fungizide entgegen.To prevent mold growth in wood-based panels, which include wood fiber boards, the use of various substances with fungicidal action is generally known. However, many of these substances are ineligible for use in fiberboard for roofing, because they are used in the interior of a house, i. H. living space, and fungicides may affect human health. In addition, the distributed by the applicant diffusion-permeable wall and ceiling plate is certified as environmentally friendly, and this certification precludes the use of conventional fungicides.
Borate werden als Flammschutzmittel für Lignocellulose haltige Baumaterialien, wie beispielsweise Isolierschüttungen verwendet und gelten aus Umweltgesichtspunkten als weitgehend unbedenklich. Die Konzentration, in der Borate als Flammschutzmittel eingesetzt werden, liegen bei typischerweise 8 % atro Fasern. Von Boraten ist es auch bekannt, dass sie eine fungizide Wirkung haben, die ab einer Konzentration von etwa 1 % atro Fasern für einen wirksamen Schimmelschutz ausreichend ist. Da der Bindemittelanteil atro Fasern bei Holzfaserplatten, die Gegenstand der vorliegenden Erfindung sind, typischerweise in derselben Größenordnung liegt, wie sie für einen Schimmelschutz durch Borate erforderlich ist, und sogar kleiner ist als die Menge, in der Borate als Flammschutz eingesetzt werden, muss ein Verfahren zur Herstellung einer Holzfaserplatte mit einem derartigen Schimmel- oder Flammschutz auf das Vorliegen relativ großer Boratmengen speziell abgestimmt werden. Hiermit sind neben den Kosten für die Borate weitere zusätzliche Kosten verbunden.Borates are used as flame retardants for lignocellulosic building materials, such as insulating fillings and are considered environmentally harmless. The concentration of borates used as flame retardants is typically 8% atro fibers.

Der Erfindung liegt die Aufgabe zugrunde, eine Holzfaserplatte für den Dach- und Wandbau und ein Verfahren zu ihrer Herstellung aufzuzeigen, durch die ein ausreichender Schimmelschutz mit minimalem Aufwand, d. h. insbesondere mit minimalem Eintrag von Fremdstoffen in die Holzfaserplatte und minimaler Erhöhung der Kosten für die Herstellung der Holzfaserplatte erreicht wird.The invention has for its object to provide a wood fiber board for roof and wall construction and a method for their preparation, by the sufficient mold protection with minimal effort, ie in particular with minimal entry of Foreign material into the fiberboard and minimal increase in the cost of producing the fiberboard is achieved.
Die Lösung dieser Aufgabe wird erfindungsgemäß durch eine Holzfaserplatte mit den Merkmalen des unabhängigen Patentanspruchs 1 und durch ein Verfahren zur Herstellung einer solchen Holzfaserplatte mit den Merkmalen des unabhängigen Patentanspruchs 4 gelöst. In den abhängigen Patentansprüchen sind bevorzugte Ausführungsformen der neuen Holzfaserplatte und des neuen Verfahrens beschrieben.The solution of this object is achieved by a wood fiber board with the features of
Die neue Holzfaserplatte weist Borate in einer Flächenkonzentration von nicht weniger als einem Gramm und von nicht mehr als 25 Gramm pro Quadratmeter auf. Diese Borate sind im Bereich der beim Verbau nach innen, d.h. der beim Dachbau nach unten auszurichtenden Hauptseite der Holzfaserplatte konzentriert. Aus diesem Grund ist die Menge der Borate bei der neuen Holzfaserplatte auch als Flächenkonzentration und nicht als Volumenkonzentration definiert. Bei einer Plattendicke der Holzfaserplatte von 16 mm und einer Rohdichte der Holzfaserplatte von 565 kg/m3 entspricht die bei der neuen Holzfaserplatte vorhandene Menge an Boraten weniger als 0,3 % atro Fasern. Dieser Wert wäre für einen wirksamen Schimmelschutz im Volumen der Holzfaserplatte völlig unzureichend. Da die Borate bei der neuen Holzfaserplatte jedoch an einer ihrer Hauptseiten, und zwar der Hauptseite, an der der Schimmelbildung vorgebeugt werden soll, konzentriert sind, reicht die Boratkonzentration dennoch aus, um einen guten Schimmelschutz herbeizuführen. Aufgrund der vergleichsweise geringen Gesamtmenge der Borate sind die Kosten für die neue Holzfaserplatte gegenüber einer Holzfaserplatte ohne Schimmelschutz nur leicht erhöht. Es ist auch nicht notwendig, das Verfahren zu ihrer Herstellung wesentlich zu verändern. Letztlich ist der Eintrag an Fremdstoffen in die Holzfaserplatte so gering, dass diese ihre Unbedenklichkeit aus Umweltgesichtspunkten nicht verliert, zumal Borate in dieser Beziehung als grundsätzlich wenig kritisch anzusehen sind.The new fiberboard has borates in an area concentration of not less than one gram and not more than 25 grams per square meter. These borates are in the area of the shoring inward, ie concentrated in the roof down to align main side of the wood fiber board. For this reason, the amount of borates in the new fiberboard is also defined as the area concentration and not the volume concentration. With a board thickness of the wood fiber board of 16 mm and a bulk density of the wood fiber board of 565 kg / m 3 , the amount of borates present in the new wood board is less than 0.3% of atro fibers. This value would be completely inadequate for effective mold protection in the volume of fiberboard. However, since the borates in the new fiberboard are concentrated at one of its major sides, the main side where mold is to be prevented, borate concentration is still sufficient to provide good mold protection. Due to the relatively small total amount of borates, the cost of the new wood fiber board compared to a wood fiber board without mold protection are only slightly increased. It is also not necessary to significantly change the process for their preparation. Ultimately, the entry of foreign matter in the wood fiber board is so low that it does not lose their safety from an environmental point of view, especially since borates are to be regarded as fundamentally less critical in this respect.
Besonders bevorzugt ist es bei der neuen Holzfaserplatte, wenn sich die Borate nicht nur auf der nach innen auszurichtenden Hauptseite der Holzfaserplatte befinden, sondern sowohl an als auch unter der Oberfläche der Holzfaserplatte an dieser Hauptseite vorliegen. So wird ein Abrieb der Borate bei ihrem Handling, einschließlich des Stapelns von Holzfaserplatten, und auch ein rasches Abwaschen der Borate unter Einwirkung von Feuchtigkeit verhindert. Grundsätzlich ist die Gefahr, dass die Borate beispielsweise durch an der Innenseite der Holzfaserplatten kondensierendes Wasser ab- und ausgewaschen werden, so dass sie unwirksam werden, relativ gering, weil die Wasserlöslichkeit von Boraten stark temperaturabhängig ist und bereits bei einer erniedrigten Temperatur von 10 °C nur noch bei etwa 100 g/l liegt. Auch Witterungseinflüsse auf der Baustelle sind daher nicht mit der sofortigen Gefahr verbunden, dass die Borate aus ihrem Bereich an der beim Verbau nach innen ausgerichteten Hauptseite der Holzfaserplatten verloren gehen.It is particularly preferred in the new wood fiber board, if the borates are not only on the main side of the wood fiber board to be aligned inside, but both as well as below the surface of the fiberboard on this main page. Thus, abrasion of the borates is prevented in their handling, including the stacking of wood fiber boards, and also a rapid washing away of the borates under the influence of moisture. In principle, the risk that the borates are washed off and washed off, for example, by water condensing on the inside of the wood fiber boards, so that they become ineffective, is relatively low because the water solubility of borates is strongly temperature-dependent and even at a reduced temperature of 10 ° C. only at about 100 g / l. Also weather influences on the construction site are therefore not associated with the immediate danger that the borates are lost from their area at the inboard facing main side of the wood fiber boards.
Um dem Verwender einen eindeutigen Hinweis darauf zu geben, welche der beiden Hauptseiten der Holzfaserplatte beim Verbau nach innen auszurichten ist, kann die entsprechende Hauptseite mit einer Markierung versehen sein. Der einseitige Zusatz der Borate im Bereich zu einer Hauptseite der Holzfaserplatten ist normalerweise nicht sichtbar. Er kann jedoch durch Farbstoffe, die z. B. den Boraten direkt zugeschlagen werden, sichtbar gemacht werden. Es ist auch möglich, die Hauptseiten mit aufgedruckten Hinweisen auf ihre vorzunehmende Ausrichtung zu versehen. Im einfachsten Fall werden die neuen Holzfaserplatten so auf Paletten gestapelt, wie es ihrer später vorzunehmenden Ausrichtung entspricht, d. h. z.B. mit ihren beim Dachbau nach unten auszurichtenden Hauptseiten nach unten. Wenn diese Orientierung der Holzfaserplatten beibehalten wird, ist keine Markierung an den Holzfaserplatten selbst notwendig.In order to give the user a clear indication of which of the two main sides of the fiberboard is to be aligned inward during installation, the corresponding main page may be provided with a mark. The one-sided addition of borates in the area to a main side of the wood fiber boards is usually not visible. He can, however, by dyes that z. B. the borates are struck directly, made visible. It is also possible to provide the main pages with printed instructions on their orientation to be made. In the simplest case, the new wood fiber boards are stacked on pallets, as it corresponds to their subsequent alignment, d. H. e.g. with their roof sides down to be aligned main pages down. If this orientation of the wood fiberboards is maintained, no marking on the fiberboard itself is necessary.
Bei dem neuen Verfahren zur Herstellung der Holzfaserplatte werden die Borate in einer Flächenkonzentration von nicht weniger als 1 Gramm und nicht mehr als 25 Gramm pro Quadratmeter auf eine Hauptseite des Faserkuchens, der zu der Holzfaserplatte verpresst wird, oder der Holzfaserplatte selbst aufgebracht, wobei diese Hauptseite die beim Verbau nach innen auszurichtende Hauptseite der Holzfaserplatte ausbildet. Die Borate können also schon vor dem Heißverpressen auf den Faserkuchen oder erst nach dem Heißverpressen auf die schon im Wesentlichen fertige Holzfaserplatte aufgebracht werden. Bevorzugt ist jedoch das Aufbringen auf den Faserkuchen, weil hierdurch eine stärkere Einbindung in das an die später innere Hauptseite angrenzende Volumen der Holzfaserplatte erfolgt.In the new method of producing the wood fiber board, the borates are applied in an area concentration of not less than 1 gram and not more than 25 grams per square meter to a main side of the fiber cake pressed to the wood fiber board or the wood fiber board itself the lining to be aligned inside the main side of the wood fiber plate forms. The borates can thus be applied to the already substantially fiberboard before the hot pressing on the fiber cake or after hot pressing. Preferably, however, is the application to the fiber cake, because in this way a stronger involvement in the adjacent to the later inner main page volume of wood fiber board is done.
Die Borate können beispielsweise durch Berieseln des Faserkuchens mit trockenen Boraten oder durch Aufwalzen oder Aufsprühen der Borate auf den Faserkuchen oder die Holzfaserplatte aufgebracht werden. Günstig ist es, wenn die Borate beim Aufbringen in Form einer Lösung, insbesondere einer Lösung in Wasser, vorliegen. Das verdampfende Wasser lässt die Borate zurück und führt zu keiner Fremdstoffbelastung der Holzfaserplatte.For example, borates may be applied to the fiber cake or fiberboard by sprinkling the fiber cake with dry borates or by rolling or spraying the borates. It is favorable if the borates are present during application in the form of a solution, in particular a solution in water. The evaporating water leaves the borates back and does not lead to contamination of the fiberboard.
In der derzeit am meisten bevorzugten Ausführungsform des neuen Verfahren werden die Borate in Form einer Lösung in Wasser von oben auf den Faserkuchen aufgesprüht, wobei das mit den Boraten aufgebrachte Wasser beim einschließenden Heißverpressen der Faserplatten verdampft wird. Die zurückbleibenden Borate sind dann so in das Volumen der Holzfaserplatte nahe ihrer unteren Hauptseite eingebunden, das ein ungewolltes Auswaschen durch Kondensationswasser oder das Handling der Holzfaserplatten oder direkte Witterungseinflüsse auf die Holzfaserplatten auf einer Baustelle zuverlässig verhindert wird.In the presently most preferred embodiment of the new process, the borates are sprayed onto the fiber cake from above in the form of a solution in water, whereby the water applied with the borates is vaporized during the hot pressing of the fibreboards. The remaining borates are then incorporated into the volume of the fiberboard near their lower main page, which reliably prevents unwanted washing out by condensation water or the handling of the wood fiber boards or direct weather influences on the wood fiber boards on a construction site.
Wenn die Borate von oben auf den Faserkuchen vor dem Heißverpressen aufgebracht werden, ist es bevorzugt, dass die Holzfaserplatte nach dem Heißverpressen gewendet und mit ihrer die Borate aufweisenden Hauptseite nach unten weiter bearbeitet, d. h. beispielsweise verpackt und transportiert, wird. Insbesondere ist es bevorzugt, wenn die Holzfaserplatte mit anderen identischen Holzfaserplatten zu einem Stapel gestapelt wird, in dem die beim Dachbau nach unten auszurichtende Hauptseite der Holzfaserplatten jeweils unten liegt. Allein dadurch sind die Borate vor Witterungseinflüssen, beispielsweise Regen auf den Stapel, geschützt. Zudem wir ein Hinweis darauf gegeben, in welcher Orientierung die Holzfaserplatten zu verbauen sind.When the borates are applied to the fiber cake from above prior to hot pressing, it is preferred that the fibrous board be turned after hot pressing and further processed downwardly with its main side containing the borates, i. H. packed and transported, for example. In particular, it is preferred if the wood fiber board is stacked with other identical wood fiber boards to form a stack in which the main side of the wood fiber boards to be aligned downwards in the roof construction lies at the bottom. This alone protects the borates from the effects of the weather, for example rain on the pile. In addition, we give an indication of the orientation in which the wood fiber boards are to be installed.
Ein anderer oder zusätzlicher Hinweis auf die sinnvolle Orientierung der neuen Holzfaserplatten beim Verbau kann im Rahmen ihrer Herstellung dadurch gegeben werden, dass zusammen mit den Boraten ein Farbstoff auf die eine Hauptseite des Faserkuchens oder der Holzfaserplatte aufgebracht wird, die die beim Verbau nach innen auszurichtende Hauptseite der Holzfaserplatte ausbildet.Another or additional indication of the meaningful orientation of the new wood fiber boards in the construction can be given in the context of their production, that together with the borates, a dye is applied to the one main side of the fiber cake or the wood fiber board, which is to be aligned inside the main side the fiberboard forms.
Die bislang angegebene Obergrenze für die Flächenkonzentration der Borate von nicht mehr als 25 g/m2, die bei einer 16 mm dicken Holzfaserplatte von 565 kg/m3 Rohdichte weniger als 0,3 % atro Fasern entspricht, muss nicht ausgeschöpft werden, um den gewünschten Schimmelschutz bereitzustellen. Dieser wird auch mit maximal 20 g/m2 für sehr lange Zeiträume erreicht. Selbst bei 8 bis 10 g/m2 kann mit einem Schimmelschutz bei einem noch nicht isolierten Dach von etwa einem halben Jahr gerechnet werden. Ein in aller Regel bereits völlig ausreichender Schimmelschutz von mindestens zwei Monaten wird bereits mit etwa 6, d.h. 5 bis 7 g/m2 zuverlässig erreicht. Eine darunter liegende Flächenkonzentration der Borate vermag nur einen verkürzten Schutz zu bewirken. Eine Flächenkonzentration von weniger als 2 g/m2 ist bereits im Wesentlichen wirkungslos.The previously stated upper limit for the boron surface concentration of not more than 25 g / m 2 , which corresponds to less than 0.3% of atro fibers for a 16 mm thick fibreboard of 565 kg / m 3 gross density, need not be exhausted in order to obtain the provide desired mold protection. This is also achieved with a maximum of 20 g / m 2 for very long periods. Even with 8 to 10 g / m 2 can not with a mold protection at one insulated roof of about half a year can be expected. A usually completely sufficient mold protection of at least two months is reliably achieved with about 6,
Als Borate zur Verwendung bei der neuen Holzfaserplatte und deren Herstellung kommen vor Allem anorganische Borate, insbesondere Alkali-, Erdalkali- und/oder Ammoniumborate, in Frage. Diese Borate sind einerseits kostengünstig verfügbar und andererseits unter Umweltgesichtspunkten weitestgehend unbedenklich. Mit Umweltgesichtspunkten ist hier sowohl der Einfluss der Holzfaserplatte auf das Wohnklima in einem angrenzenden Wohnraum als auch die Recyclebarkeit der Holzfaserplatte gemeint.Suitable borates for use in the novel wood fiber board and their production are, in particular, inorganic borates, in particular alkali metal, alkaline earth metal and / or ammonium borates. These borates are on the one hand cost-effective and on the other hand largely harmless from an environmental point of view. From an environmental point of view, this means both the influence of the wood fiber board on the living climate in an adjacent living space and the recyclability of the wood fiber board.
Als in günstiger Weise für die neue Holzfaserplatte und das Verfahren zu deren Herstellung verwendbar haben sich kommerzielle Flammschutzmittel auf der Basis von anorganischen Boraten erwiesen, diie jedoch im Rahmen der vorliegenden Erfindung in außergewöhnlich geringer Konzentration und damit entgegen den Herstelleranweisungen verwendet werden.Commercially available flame retardants based on inorganic borates have proven to be useful for the novel fiberboard and the process for their production, but they are used in the context of the present invention in exceptionally low concentration and thus contrary to the manufacturer's instructions.
