Description
Verfahren zur Herstellung von Leichtbauplatten oder anderen Bauformteilen aus aus Zellulosefasern aufgebauten Stoffen in Mischung mit Zement oder anderen mineralischen Bindemitteln Die bisher im Bauwesen bekannten a-glomerierten Leichtbauplatten und andere Bauformteile, welche hauptsächlich aus Holzfasern (Holzwolle), Spänen, Stroh, Zellulose und pflanzlichen Stoffen und Abfällen hergestellt sind und hei deren Herstellung Gips, Magnesit, Zement u. dgl. als Bindemittel =.gewendet #vcrd-,-n, sind in der Weise her-,#;-#stellt, daß zu ihrer Erzeugung und Bindung verschiedene Emulsionen eines oder mehrerer Bindemittel angewendet werdea, zu welchen verschi-ed-en#e chemisch-,- Stoffe, wie Chl-orcalcium, Chlormagnesium, Wasserglas, Kieserit, Kochsalz, kaustische Soda u. d#,:1., zw,-cks #Xlineralisai `on der Fasern zugesetzt sind. Nach diesen bekannten Verfahren hergestellte Leichtbauplatten und Bauformteile, die aus Zellulosefasern aufgebaute Stoffe, insbesondere Holzwolle in Mischung mit Zemcnt oder anderen, mineral,ischen Bindemitteln enthalten, stellen in vielen Fällen kein vollwertiges, allen Bauansprüchen entsprechendes Baumatürial dar. Durch den Zusatz von verschiedenen chemischen Stoffen wird dieHerstellung umständlich und das Endprodukt teuer. Außerdem werden durch di--, zugesetzten chemischen Stoffe die Bauplattven zum Schad-en ihrer 1-7,-stigkeit und Beständigkeit stark hygroskopiert.Process for the production of lightweight panels or other structural parts made of materials made up of cellulose fibers mixed with cement or others mineral binders The a-glomerised lightweight panels known so far in construction and other structural parts, which are mainly made of wood fibers (wood wool), shavings, Straw, cellulose and vegetable matter and waste are made and hot their production gypsum, magnesite, cement, etc. as binders =. turned #vcrd -, - n, are made in the way -, #; - # makes that different to their generation and bonding Emulsions of one or more binders are used, to which different chemical -, - substances such as chlorcalcium, chloromagnesium, water glass, kieserite, common salt, caustic soda and d #,: 1., zw, -cks #Xlineralisai `on the fibers are added. Lightweight panels and structural parts manufactured according to these known processes, the fabrics made up of cellulose fibers, especially wood wool in a mixture with In many cases, cement or other mineral binders contain them does not represent a full-fledged building natural that meets all building requirements The addition of various chemical substances makes the production cumbersome and the end product expensive. In addition, by di--, added chemical substances the building boards are heavily hygroscopic to damage their 1-7 strength and durability.
Nach dem Verfahren gemäß der Erfindung erhält man aus Holzwolle und anderen Stoffen mit Zellulosefasern in Mischung mit Zement oder anderen mineralischen Bindemitteln eine einheitliche Masse, so daß aus zwei heterogenen Matelrialien ohne irgendwelchen Zusatz von chemischen Stoffen Enderzeugnisse mit fester Struktur her-Gill e entliche Biegungs-,' stellt werden, di außerord festigkeit und Druckfestigkeit besitzen.According to the method according to the invention is obtained from wood wool and other materials with cellulose fibers in a blend with cement or other mineral binders uniform ground, so that entliche of two heterogeneous Matelrialien without any addition of chemicals finished products with a fixed structure forth Gill e Biegungs- , 'will be, which have extraordinary strength and compressive strength.
Im folgenden wird das Verfahren zur Herstellung von Leichtbauplatten oder anderen Bauformteilen aus Holzwolle und Zement beschrieben. Das Verfahren. kann auch zur Herstellung von Leichtbauplatten und anderen Bauformteilen aus Holzabfällen von der Ho-lzb.-arbeitung, z. B. aus zerkleinerte:m Holzmaterial, Sägespünen und anderen aus Zellulosefasern aufgebauten Stoffen, wie Hanfschäben, Abfällen von Pflanzenstenggeln u. dgl., angewendet werden.The following is the process for producing lightweight panels or other structural parts made of wood wool and cement. The procedure. can also be used to manufacture lightweight panels and other structural parts from waste wood from woodworking, e.g. B. from shredded: m wood material, sawdust and other materials made up of cellulose fibers, such as hemp shives, waste from plant stems and the like.
Das nach dem Verfahren verarbeitete Holzmaterial soll aus gesundem Nadelholz oder weichen Laubhälzern (Fichte, Tanne, Pappel, Weide, Linde Erle usw.) bestehen.The wood material processed according to the procedure should be made from healthy Softwood or soft deciduous trees (spruce, fir, poplar, willow, linden, alder, etc.) exist.
Aus Nadelholz hergestellte Erzeugnisse sind qualitativ besser als die aus Laubholz. In gewissen Fällen kann man Holzmaterial beider Holzarten miteinander mischen, wobei au*ch Holzwolle aus Kiefernholz benutzt werden kann. Es ist bekannt, daß die Fasern auch nach der Trennung vom Baumstamm alle ursprünglichen organischen Bestandteile besitzen, wie Harze, Klebe- und Farbstoffe, Säuren, Staub usw, die der Aufnahme von Zementteilchen hinderlich sind.Products made from softwood are of better quality than those made of hardwood. In certain cases, wood material of both types of wood can be used together Mix, whereby wood wool from pine wood can also be used. It is known, that the fibers are all original organic even after separation from the tree trunk Have constituents such as resins, adhesives and dyes, acids, dust, etc., which obstruct the absorption of cement particles.
Deshalb. mußten nach den bekannten Verfahren Holzwolle und andere aus 7,ellulos,efasern aufgebaute Stoff.- mit verschiedenen Emulsionen, z. B. Kallzmilch, unter Zusatz von verschieden.en. chemischen Stoffen mineralisiert -werden, um in Mischung mit Zement oder anderen mineralischen Bindemitteln eine innige Bindung zu erzielen.That's why. had to use the known methods of wood wool and others fabric built up from 7, ellulos, efibers - with different emulsions, e.g. B. Kallzmilch, with the addition of various. chemical substances -being mineralized in order to be put in Mixing with cement or other mineral binders creates an intimate bond to achieve.
Das neue Verfahren zur Herstellung von Leichthauplatten und anderen Bauforniteilen, aus aus Zellulosefasern, aufgebauten Stoffen, insbesondere Holzwolle, in Mischung mit Zement und anderen mineralischen Bindemitteln besteht darin, daß man die Holzwolle oder den -aus Zellulosefasern aufgebauten Stoff vor dem Zusammenbringen mit den Bindemitteln während 15 bis 2-o Minuten oder länger in. Wasser kocht. Dadurch wird die Auf- nahme der Zementteilchen in die Poren des Materials ermöglicht und eine homogene und kahäsive Bindung mit Zement ohne irgendwelchen Zusatz von chemischen Stoffen und ohne vorherige Mineralisation erzielt. Das Material wird so lange gekocht, bis das Wasser eine licht-braune Farhe erhält.The new process for the production of lightweight panels and other structural parts, made of cellulose fibers, composed of materials, especially wood wool, mixed with cement and other mineral binders, consists in that the wood wool or the material composed of cellulose fibers before being brought together with the binders during Boiling water in 15 to 2-o minutes or more. Characterized the up will acquisition of the cement into the pores of the material allows, and obtained a homogeneous and kahäsive bond with cement without any addition of chemicals and without mineralization. The material is boiled until the water turns a light brown color.
Durch Kochen in siedendem Wasser wird Holzwolle und ähnlicher aus Zellulosefasern aufgebauter Stoff von allen obenerwähnten, Bestandteilen sowie auch von Staub befreit, und die Zellen werden abz,e 011 tötet, wobei das Material die natürliche Elastizität behält und in den fertigen Erzeugnissen. auf die Wirkung von Feuchtigkeit Kälte und Wärine nicht reagiert. Aus der Masse hergestellt-,- Bauteile erleidend keine Änderung ihrer ursprünglichen Ab- messungen. Sie werden mit der Zeit nicht mürbe und sind nicht dem Faulen und Zersetzen unterworfen.By boiling in boiling water, wood wool and similar materials made up of cellulose fibers are freed of all the above-mentioned constituents as well as dust, and the cells are killed, whereby the material retains its natural elasticity and in the finished products. does not react to the effects of moisture, cold and warmth. Made of the mass -, - components erleidend measurements no change to its original intentions. They do not become tender over time and are not subject to putrefaction and decomposition.
Das nach dem neuen Verfahren durch Kochen vorbereitete Material, vorzugsweise Holzwolle, wird sodann in bekannter Weise mit Zement bestreut und tüchtig gemischt, so daß das Z--rn-entpulv,-r die ganze Oberfläche der Fasern bedeckt, und dann in die dazu bestimmten Formen gepreßt und nach der Abbindez-eit getrocknet. Die Erzeugung der Leichtbauplatten und anderer Bauformteile wird vorzugsweise mit mechanischen Mitteln und kontinuierlich durchgeführt.The material prepared by boiling according to the new method, preferably Wood wool, is then sprinkled with cement in the known manner and mixed thoroughly, so that the Z - rn-entpulv, -r covers the whole surface of the fibers, and then in the specific shapes are pressed and dried after the setting time. The production The lightweight panels and other structural parts are preferably made with mechanical Medium and carried out continuously.
