Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von auf Zellulosefaser-/Bindemittelsystemen basierenden Beschichtungen auf Gebäudeflächen, insbesondere im Vor-Ort-Verfahren.The present invention relates to a method for producing Coatings based on cellulose fiber / binder systems Building surfaces, especially using the on-site procedure.
Im Stand der Technik ist es bekannt, Gebäudeflächen, insbesondere Wände und Fußböden, vorzugsweise mit Sprühsystemen zu beschichten, um auf diese Weise Dämmbeschichtungen vor Ort zu erzeugen. Hierzu sind mobile Vorrichtungen bekannt.It is known in the prior art to use building surfaces, in particular walls and Floors, preferably with spray systems to coat in this way To produce insulation coatings on site. Mobile devices are for this purpose known.
Die bekannten Systeme haben insbesondere den Nachteil, daß sich Decken zumindest nicht ohne Verstrahlung beschichten lassen und die Schichten sich hinsichtlich Konsistenz nicht steuern lassen. Insbesondere kommt es häufig vor, daß die erzeugten Schichten nichtgebundene Trockenbereiche aufweisen, die zum einen ihre Funktion als Dämmbeschichtung nicht ausüben können, zum anderen zu späteren Ausbruchschäden führen.The known systems have the particular disadvantage that there are ceilings at least not to be coated without radiation and the layers themselves not to be controlled in terms of consistency. In particular, it often happens that the layers produced have non-bonded dry areas leading to one cannot perform its function as an insulation coating, on the other lead to later outbreak damage.
Ausgehend vom vorbekannten Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art dahingehend zu verbessern, daß sich weitestgehend homogene und gut haftende Schichten ausbringen lassen, die vorzugsweise auch ohne die Nutzung besonderer Schalungen über Kopf auf Decken anbringen lassen. The present invention is based on the prior art the task underlying a method of the generic type to improve in such a way that it is largely homogeneous and adheres well Spread layers, preferably without using have special formwork installed overhead on ceilings.
Zur technischen Lösung wird mit der Erfindung ein Verfahren zur Herstellung von auf Zellulosefaser-/Bindemittelsystemen basierenden Beschichtungen auf Gebäudeflächen vorgeschlagen, wobei zerfaserte Zellulosefaserflocken unter Druck in eine Ausbringdüse gefördert, angefeuchtet und auf die Fläche aufgeworfen werden, um unter Bindemitteltrocknung auszuhärten.With the invention, a method for manufacturing becomes a technical solution of coatings based on cellulose fiber / binder systems Building surfaces are proposed, with fiberized cellulose fiber flakes underneath Pressure is conveyed into a dispensing nozzle, moistened and applied to the surface be thrown up to harden with binder drying.
Bei dem erfindungsgemäßen Verfahren werden die Zellulosefaserflocken nach der Zerfaserung in einem Reservoir gehalten und unter Druck in eine Ausbringdüse gefördert, wo sie angefeuchtet werden. Durch den Druck wird das Gemenge auf die Fläche aufgeworfen, wo unter Trocknung des Bindemittels eine Aushärtung stattfindet.In the method according to the invention, the cellulose fiber flakes according to the Fibering kept in a reservoir and under pressure in a dispensing nozzle promoted where they are moistened. The mixture is opened up by the pressure thrown up the area where curing while drying the binder takes place.
Der Druck wird vorzugsweise von einem Gebläse aufgebracht, beispielsweise mit einem Luftstrom von 270 m3/h. Bindemittel können in den Zellulosefaserflocken eingemengt sein. Ebenso können Additive wie Brandschutzmittel, beispielsweise Borate zur Erzeugung einer bestimmten Brandschutzklasse und dergleichen mit den Flocken vermengt sein. Flockenrestfeuchten von 4 bis 20% haben sich als handhabbar erwiesen.The pressure is preferably applied by a blower, for example with an air flow of 270 m 3 / h. Binders can be mixed into the cellulose fiber flakes. Additives such as fire protection agents, for example borates for producing a specific fire protection class and the like, can also be mixed with the flakes. Flake residual moisture of 4 to 20% has proven to be manageable.
Die Anfeuchtung erfolgt vorzugsweise in der Ausbringdüse, indem ein Lösemittel dort vernebelt wird. Durch die Erzeugung eines Lösemittelnebels kommt es zu einer hervorragenden Anfeuchtung sämtlicher Flocken, die sich in einem chaotischen, also ungerichteten Verbund auf der beworfenen Fläche ansammeln. Als Lösungsmittel kommen beispielsweise verdünnte Latexlösungen in Betracht. Diese kann mit einer Pumpe in ein Vernebelungssystem eingepumpt werden, welches sich in einer Vernebelungsdüse im Inneren einer Ausbringdüse befindet. Die Latexlösung kann eine Feststoffkonzentration von 5% aufweisen. Die Latexlösung hat vorzugsweise eine ausreichende Viskosität, um trotz Vernebelung einen guten Verbund hervorzurufen.Moistening is preferably carried out in the dispensing nozzle using a solvent is nebulized there. It is caused by the generation of a solvent mist an excellent moistening of all flakes, which are in one accumulate chaotic, i.e. undirected composite on the thrown surface. Diluted latex solutions are suitable as solvents, for example. This can be pumped into a nebulizer system, which is located in a nebulizing nozzle inside a dispensing nozzle. The latex solution can have a solids concentration of 5%. The Latex solution preferably has a sufficient viscosity to despite nebulization to create a good bond.
Von einem Reservoir über Zellradschleusen in den Luftstrom gebracht, werden die Zellulosefaserflocken in die Ausbringdüse befördert und umströmen dort die Vernebelungsdüse, treten also durch die von der Vernebelungsdüse erzeugte Vernebelungstraube nach außen. Bei Verwendung eines Verdickers lassen sich selbst Decken beaufschlagen, wobei die aufgetragene Beschichtung sofort dauerhaft und langsam über die Raumluft austrocknet. Hydrokolloide erzeugen beim Auftreffen des wäßrigen Systems ein sofortiges Quellen bzw. eine starke Viskositätserhöhung. Die Flocken können vorgefärbt sein.They are brought into the air flow from a reservoir via cellular wheel sluices Cellulose fiber flakes are conveyed into the discharge nozzle and flow around them Nebulization nozzle, so pass through that generated by the atomization nozzle Nebulization cluster outside. When using a thickener, even cover blankets, applying the applied coating immediately dries out permanently and slowly in the air. Generate hydrocolloids an immediate swelling or a strong one when the aqueous system strikes Viscosity increase. The flakes can be pre-colored.
Das erfindungsgemäße Verfahren ermöglicht eine sehr exakte Steuerung der Auswerfdrücke und der Flockendurchfeuchtung, also des endgültig erzeugten Gemenges, so daß sich selbst an Decken gut haftende Beschichtungen erzeugen lassen, die sich aufgrund der verwendeten Drücke auch im Überkopf-Verfahren erstellen lassen.The method according to the invention enables very precise control of the Ejection pressures and the wetness of the flakes, i.e. the finally generated Batch, so that coatings adhere well to ceilings can, because of the pressures used, also in the overhead process let create.
Das erfindungsgemäße Verfahren läßt auf einfache Weise sehr wirksam gut haftende und homogenisierte Schichten auf Gebäudeflächen erzeugen, so daß das Verfahren gegenüber bekannten Verfahren einfacher und wirtschaftlicher ist.The method according to the invention leaves very effectively well in a simple manner generate adhesive and homogenized layers on building surfaces so that the process is simpler and more economical than known processes.
