Description
Die Erfindung betrifft ein Verfahren zur Herstellung geformter und gebrannter Bauelemente aus Schaumton.The invention relates to a process for the production of molded and fired foam clay components.
Zur Erreichung dieses allgemeinen Zieles ist eine Vielzahl von Ansätzen technischer Lösungen bekannt geworden, die sämtlich unter bestimmten Aspekten nicht befriedigen und daher allenfalls als Teillösungen des oben genannten allgemeinen Problems anzusehen sind. Dabei erfolgt, wie bei der Erfindung eine Beschränkung auf technische Lösungen, die im wesentlichen anorganische steinartige Werkstoffe ergeben.To achieve this general purpose, a large number of approaches to technical solutions have become known, all of which are unsatisfactory under certain aspects and, therefore, may at most be regarded as partial solutions to the abovementioned general problem. In this case, as in the invention, a restriction to technical solutions that result in substantially inorganic stone-like materials.
Dabei sind prinzipiell drei Gruppen technische Lösungen zu unterscheiden:
- 1. In sich geschäumte Massen homogener stofflicher Zusammensetzung
- 2. Ungeschäumte Bindemittel mit porösen Füllstoffen, insbesondere Blähglasgranulat, und
- 3. Erzeugnisse bei denen, wie bei der Erfindung, das Bindemittel, welches die porösen Füllstoffe zusammenhält, ebenfalls geschäumt ist.
- 1. Foamed masses of homogeneous material composition
- 2. Unfoamed binders with porous fillers, in particular expanded glass granules, and
- 3. Products in which, as in the invention, the binder which holds the porous fillers is also foamed.
Zur ersten Gruppe ist ein Verfahren zur Herstellung einer feinporigen Schaumwerkstoffes aus einer anorganischen steinbildenden Masse, einem alkalischen Härter sowie einem oberflächenaktiven amphiphilen Schaumbildner bekannt (
Bei der Herstellung eines geformten und gebrannten porosierten Mauerziegels wird die Masse mittels eines Tensidschaumes aufgeschäumt, welcher Kieselsäure als Stabilisator enthält (
Sehr vorteilhaft für die Festigkeit wirkt es sich aus, wenn Blähglasgranulat bei der normalen Ziegelherstellung in der Weise eingesetzt wird, wenn an der Grenzfläche zwischen Ziegelmasse und hochporösen Blähglasgranulat beim Ziegelbrand eine Reaktion erfolgt, aber der Brand derart gesteuert wird, daß die Raumstruktur des Blähglasgranulates erhalten bleibt (
Eine Zusatzpatentanmeldung zu dieser technischen Lösung (
Eine Formmasse für Wärmedämmplatten besteht aus einem sehr hohen Anteil von 35 Masse% bis 75 Masse% Blähglasgranulat mit Wasserglas als notwendigem sowie Tonerdezement und Flugasche als fakultativen Bindemitteln (
Bei einem Formkörper ähnlicher Zusammensetzung, bei welchem das Bindemittel eine Geopolymerbindung ausbildet und vorzugsweise noch amorphes Siliziumoxid, aktivierte Tone, Glaspulver und/oder hochaufgemahlenen Basalt enthält, wird die Bindemittelphase selbst nicht geschäumt, aber die Porosität des Formkörpers soll dadurch über den Porositätswert, welcher dem zugesetzten Blähglasgranulat entspricht, hinaus gesteigert werden, indem das Bindemittel die Blähglasgranalien lediglich benetzt, so dass zu den Hohlräumen (Poren) in den Blähglasgranalien noch diejenigen zwischen diesen hinzukommen, soweit sie nicht vom Bindemittel ausgefüllt sind (
Schließlich ist es bekannt, ein Gemisch abgestufter Korngrößen eines Hohlraummaterials, darunter auch Blähglasgranulat aber auch organisches Hohlraummateriel, wie solches aus Polystyren oder auch Holzspäne, derart mit einem geschäumten Bindemittel aus Wasserglas, Metakaolin sowie verschiedenen in der Keramik verwendeten Oxiden zu verfestigen, daß die Oberfläche der Hohlraumpartikel mit einer dünnen, geschäumten Bindemittelschicht überzogen sind (
Es soll noch kurz auf den Stand der Technik anorganischer, kaltaushärtender Bindemittel, welche Wasserglas enthalten, eingegangen werden, die stoffliche Berührungspunkte zur Erfindung aufweisen, ohne dass dort der Gesichtspunkt des Aufschäumens eine Rolle spielt. Der Neuheitsgehalt dieser Veröffentlichungen besteht zumeist darin, dass ganz bestimmte Feststoffe zugegeben werden. Dies betrifft beispielsweise:
- – gemahlenen kalzinierten Bauxit (
EP 199 941 B2 - – eine Kombination von Elektrofilterstaub aus Braunkohlekraftwerken mit Filterstäuben aus der Korund- oder Mullitherstellung, glasiger Elektrofilterasche und einer Vielzahl anderen an sich für diesen Anwendungsfall bekannter Stoffe (
EP 0 417 583 B1 - – bei bestimmten Temperaturen thermisch aktiverten Ton (
DE 100 11 757 A1 - – bei einer hohen Rührerdrehzahl gemischte an sich bekannte Komponenten, wodurch das Gemisch durch Einwirkung der Zentrifugalkraft verdichtet werden soll (
DE 198 55 019 A1
- - ground calcined bauxite (
EP 199 941 B2 - A combination of electrostatic precipitator dust from lignite power plants with filter dusts from corundum or mullite production, glassy electro-filter ash and a multitude of other substances known per se for this application (
EP 0 417 583 B1 - - thermally activated clay at certain temperatures (
DE 100 11 757 A1 - At a high stirrer speed mixed components known per se, whereby the mixture is to be compacted by the action of the centrifugal force (
DE 198 55 019 A1
Der zuletzt genannte Stand der Technik könnte spezielle, zur Realisierung der Erfindung bereitzustellende Komponenten, aber niemals deren allgemeinen Grundgedanken, nämlich die geschäumte Tonmasse, betreffen.The last-mentioned prior art could concern special components to be provided for the realization of the invention, but never its general basic idea, namely the foamed clay mass.
Der Erfindung liegt die Aufgabe zugrunde, bei der Herstellung geformter Bauelemente aus Schaumton, die gegenläufigen Kennwerte von Porosität und Festigkeit zu steuern.It is an object of the invention to control the opposing characteristics of porosity and strength in the manufacture of molded foam clay components.
Diese Aufgabe wird durch die in den Patentansprüchen beschriebene Erfindung gelöst.This object is solved by the invention described in the claims.
In dieser Anmeldung handelt es sich bei dem „SB 1-Schäumer” um einen kommerziellen Schaumbildner für Porenleichtbeton der Firma Addiment.In this application, the "SB 1 frother" is a commercial foaming agent for porous lightweight concrete from Addiment.
Die Erfindung wird nachstehend an zwei Ausführungsbeispielen näher erläutert, aus denen auch die vorteilhaften Auswirkungen der Erfindung hervorgehen:The invention is explained in more detail below with reference to two exemplary embodiments from which the advantageous effects of the invention also emerge.
