Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Gipskartonplatten.The invention relates to a method for producing plasterboard.
Es ist bekannt, Gipskartonplatten derart herzustellen, daß man auf eine trockene Kartonbähn flüssiges Gips gießt und eventuell anschließend eine weitere trockene Kartonbahn auf den Gips legt. Dieses Verfahren hat den Nachteil, daß der Karton und der Gips schlecht aneinanderhaften. Hinzu kommt, daß die Herstellung relativ teuer ist, da man fertige, d. h. trockene Kartonbahnen, verwenden muß.It is known to produce plasterboard in such a way that liquid is applied to a dry cardboard train Pour plaster of paris and possibly then place another sheet of dry cardboard on top of the plaster of paris. This method has the disadvantage that the cardboard and the plaster of paris adhere poorly to one another. In addition comes that the production is relatively expensive, since one finished, i. H. use dry cardboard webs got to.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden.The invention is based on the object of avoiding this disadvantage.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die gießfähige Gipsmasse mit dem als nasse Faserschicht mit einem Trockengehalt an Feststoffen von höchstens 50 4Vo vorliegenden Karton in Verbindung gebracht wird.This object is achieved according to the invention in that the pourable gypsum mass is brought into connection with the cardboard present as a wet fiber layer with a dry solids content of at most 50 4 Vo.
Auf diese Weise wird erreicht, daß man eine ausgezeichnete Haftfestigkeit zwischen dem Karton und dem Gips und damit eine gute Festigkeit der Gipskartonplatten erzielt. Hinzu kommt, daß sich die Herstellung insofern vereinfacht und verbilligt, als man den Gips mit einem Halbfabrikat, nämlich der nassen Faserschicht, zusammen verarbeitet. Man spart auf diese Weise die Anlage zur Herstellung von Kartonbahnen.In this way it is achieved that you have an excellent bond strength between the cardboard and the plaster and thus a good strength of the plasterboard achieved. In addition, the Production simplified and cheaper, as the plaster of paris with a semi-finished product, namely the wet fiber layer, processed together. This saves the production plant of cardboard webs.
Erhärtende Massen mit nassen Faserschichten in Verbindung zu bringen, ist zwar an sich bekannt, jedoch nicht auf dem Gebiet der Gipskartonplattenherstellung. Bringing hardening compounds into contact with wet fiber layers is known per se, but not in the field of plasterboard manufacture.
Die nasse Faserschicht wird als Naßbogen in an sich bekannter Weise hergestellt und besteht vorzugsweise aus einer Wassersuspension aus Zellstofffasern, die gesiebt und zusammengefilzt worden sind. Der Naßbogen ruht zweckmäßig auf einem Siebtuch, z. B. einem Flachsieb. Durch Ebenen der Oberfläche der Gießmasse kann der Wasserüberschuß in der Gießmasse durch die darunterliegende Faserschicht abgedrückt werden. Hierdurch wird außerdem eine stabile Bindung des Naßbogens an der Gießmasse erzielt, und die Flammenfestigkeit wird dadurch erhöht, daß ein Teil der Gießmasse in die Faserschicht eindringt. Die obere Fläche der Gießmasse wird dann vorzugsweise mit einem ähnlichen Naßbogen belegt.The wet fiber layer is produced as a wet sheet in a manner known per se and is preferably made from a water suspension made of cellulose fibers that have been sieved and felted together. The wet arch expediently rests on a sieve cloth, e.g. B. a flat sieve. By levels of the surface of the casting compound, the excess water in the casting compound can pass through the underlying fiber layer be pulled. This also ensures a stable bond between the wet sheet and the casting compound achieved, and the flame resistance is increased in that part of the casting compound in the fiber layer penetrates. The top surface of the potting compound is then preferably covered with a similar wet arch proven.
Von der auf diese Weise erhaltenen. Bahn kann dann weiteres Wasser abgesaugt werden, gegebenenfalls durch die darüberliegende Faserschicht, und/ oder sie kann einer Entwässerung und/oder Pressung zu endgültiger Stärke zwischen Preßwalzen oder Preßbändern unterworfen werden, die mit Siebtüchern, Gummi, Filz od. dgl bekleidet sein können.From the obtained in this way. Web can then be sucked up further water, if necessary through the overlying fiber layer, and / or it can undergo drainage and / or compression are subjected to final strength between press rolls or press belts, which with sieve cloths, Rubber, felt or the like can be clothed.
Der obenliegende Naßbogen kann auch dadurch erzeugt werden, daß die Fasersuspension auf die Gießmasse aufgetragen wird und das Überschußwasser der Fasersuspension durch die Gießrnasse und den, .darunterliegenden Naßbogen hindurchgesaugt wird.The overlying wet arch can also be produced in that the fiber suspension on the Casting mass is applied and the excess water of the fiber suspension through the casting mass and sucked through the wet sheet underneath will.
Die Erfindung wird an Hand der Zeichnung nachstehend erläutert. In der Zeichnung zeigtThe invention is explained below with reference to the drawing. In the drawing shows
F i g. 1 schematisch eine Ansicht einer Maschine zur Herstellung von Platten gemäß der Erfindung undF i g. Fig. 1 schematically shows a view of a machine for manufacturing panels according to the invention and
Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1.Fig. 2 is a section along the line II-II of Fig. 1.
Die Maschine nach F i g. 1 besitzt einen Einlauf 1, aus dem faseriges Material.auf ein Siebband2 ausströmt, das von Registerwalzen 3 getragen wird. Die Flüssigkeit des auf dem Siebband 2 gebildeten Naßbogens wird in einem Saugkasten 4 teilweise abgesaugt. Auf den Naßbogen wird Gips bei 5 gegossen, und die kombinierte Gipsfaserbahn wird anschließend über den Saugkasten 6 gefördert.The machine according to FIG. 1 has an inlet 1 from which fibrous material flows out onto a sieve belt 2, which is carried by register rollers 3. The liquid of the wet sheet formed on the sieve belt 2 is partially sucked off in a suction box 4. Plaster of paris is poured onto the wet arch at 5, and the combined gypsum fiber web is then conveyed via the suction box 6.
Bei 7 wird ein zweiter Naßbogen aufgelegt, der auf einem Siebtuch 8 gebildet worden ist. Bei 9 wird das Produkt an ein Förderband 10 übergeben, das es zu einer Trocknungsstation bringt. Die Bahn wird danach in geeignete Längen zerschnitten.At 7, a second wet sheet, which has been formed on a screen 8, is placed. At 9 will transfer the product to a conveyor belt 10 which takes it to a drying station. The train will then cut into suitable lengths.
Aus Fig. 2 ergibt sich, wie die Gipsfaserbahn 12 von einem Band 11 begrenzt wird. Die Bahn ruht auf dem Siebband 2, das seinerseits von den Registerwalzen 3 getragen wird.2 shows how the gypsum fiber web 12 is bounded by a band 11. The train rests the screen belt 2, which in turn is carried by the register rollers 3.
