Description
Verfahren zur Herstellung von Isollermassen. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Isolier massen, welches dadurch gekennzeichnet ist, dass man eine hochporöse Mischung aus Cellu- lose und Torf mit anorganischen Stoffen der art vermengt, dass durch die Stoff- und Mengen wahl der anorganischen Stoffe eine Isolier masse mit vorausbestimmtem Porositätsgrade erhalten wird.
Als anorganische Stoffe haben sich Gips, Zement, Kalk und Quarzmehl als .besonders geeignet erwiesen.
Auf diese Weise lassen sich aus einer Mischung, bestehend aus gleichen Teilen Cellu- lose und Torf mit einem Porositätsgrade von 31,9, Mischungen von 300 Gewichtsteilen Cellulose und 300 Gewichtsteilen Torf mit 600 Gewichtsteilen Gips mit einem Porositäts- grade von 14,6, ebenso Mischungen von 300 Gewichtsteilen Cellulose und 300 Gewichts teilen Torf mit 600 Gewichtsteilen Zement mit einem Porositätsgrade von 5,8,
ferner aber auch Mischungen von 50 Gewichtsteilen Celltilose und 50 Gewichtsteilen Torf mit 200 Gewichtsteilen Gips, 600 Gewichtsteilen Quarzmehl und 150 Gewichtsteilen Kalk mit einem Porositätsgrade von 3,5 und endlich auch Mischungen von 325 Gewichtsteilen Cellulose und 325 Gewichtsteilen Torf mit 400 Gewichtsteilen Kalk mit einem Poro- sitätsgrade von 0,3 herstellen.
Unter Porositätsgrad ist das hundertfache, reziproke Produkt aus der spezifischen Ein saugzeit und dem spezifischen Sättigungs volumen verstanden, wobei die Zeit, die eine Isoliermasse benötigt, um auf einer bestimmten Einsaugfläche (zum Beispiel von 25 Quadrat zentimetern), einen Kubikzentimeter Wasser einzusaugen als spezifische Einsaugzeit und die Wassermenge, die von einem Gramm der betreffenden Isoliermasse maximal eingezogen werden kann, als spezifisches Sättigungsvo lumen einer Isoliermasse bezeichnet ist.
Beispielsweise ergibt sich der Porositäts- grad der oben erwähnten hochporösen Cellu- lose-Torfmischung wie folgt: Auf eine Einsaugfläche von 25 Quadrat zentimetern des Probekörpers von zirka 1'/2 Zentimeter Dicke aus der hochporösen Celiu- lose-Torfrnischung werden 20 Kubikzentimeter Wasser gebracht. Zum restlosen Einsaugen dieser Wassermenge sind 15 Sekunden er forderlich.
Somit benötigt dieser Probekörper 0,75 Sekunden, um 1 Kubikzentimeter Wasser auf der Einsaugfläche von 25 Quadratzenti metern einzusaugen, das heisst die spezifische Einsaugzeit zi der hochporösen Cellulose- Torfmischung beträgt 0,75.
37,77 Gramm dieser lufttrockenen, hoch porösen Cellulose-Torfmischung wiegen nach ihrem Einlegen in Wasser bis zur Gewichts konstanz 195,72 Gramm. Es werden sonach von diesem 37,77 Gramm schweren Probe körper 157,95 Gramm Wasser von Zimmer temperatur, das heisst also 157,95 Kubikzenti meter Wasser maximal eingesogen. Somit saugt 1 Gramm dieses Probekörpers maximal 4,18 Kubikzentimeter Wasser ein, das heilst das spezifische Sättigungsvolumen vi der hochporösen Cellulose-Torfmischung beträgt 4,18.
Bezeichnet man den Porositätsgrad einer Isoliermasse mit ro, so ist definitionsLyemäss
EMI0002.0016
Für das angegebene Beispiel ist dahe
EMI0002.0018
Daraus resultiert der Porositätsgrad der hoch porösen Cellulose-Torfmischung zu p=31,9.
Zur Mischung der Stoffe und zu ihrer Verarbeitung bis zum Endprodukt können die bekannten Einrichtungen verwendet werden.
Process for the production of isollers. The present invention relates to a process for the production of insulating compounds, which is characterized in that a highly porous mixture of cellulose and peat is mixed with inorganic substances such that the choice of materials and quantities of the inorganic substances creates an insulating compound is obtained with a predetermined degree of porosity.
Gypsum, cement, lime and quartz powder have proven to be particularly suitable as inorganic substances.
In this way, mixtures of 300 parts by weight of cellulose and 300 parts by weight of peat with 600 parts by weight of gypsum with a porosity of 14.6 can also be made from a mixture consisting of equal parts of cellulose and peat with a porosity level of 31.9 Mixtures of 300 parts by weight of cellulose and 300 parts by weight of peat with 600 parts by weight of cement with a degree of porosity of 5.8,
but also mixtures of 50 parts by weight of cellulose and 50 parts by weight of peat with 200 parts by weight of gypsum, 600 parts by weight of quartz flour and 150 parts by weight of lime with a porosity of 3.5 and finally also mixtures of 325 parts by weight of cellulose and 325 parts by weight of peat with 400 parts by weight of lime with a porosity - Establish a degree of strength of 0.3.
The degree of porosity is the hundredfold, reciprocal product of the specific suction time and the specific saturation volume, with the time that an insulating compound needs to suck in one cubic centimeter of water on a certain suction surface (e.g. 25 square centimeters) as the specific suction time and the maximum amount of water that can be drawn in by one gram of the insulating compound in question is referred to as the specific saturation volume of an insulating compound.
For example, the degree of porosity of the above-mentioned highly porous cellulose-peat mixture is as follows: 20 cubic centimeters of water are placed on an intake area of 25 square centimeters of the test specimen about 1½ centimeters thick from the highly porous cellulose peat mixture. It takes 15 seconds to completely suck in this amount of water.
This test specimen therefore needs 0.75 seconds to suck in 1 cubic centimeter of water on the suction surface of 25 square centimeters, i.e. the specific suction time zi of the highly porous cellulose-peat mixture is 0.75.
37.77 grams of this air-dry, highly porous cellulose-peat mixture weighs 195.72 grams after soaking in water to a constant weight. 157.95 grams of room temperature water, i.e. 157.95 cubic centimeters of water, are sucked in from this 37.77 gram sample. Thus, 1 gram of this test specimen sucks in a maximum of 4.18 cubic centimeters of water, which means that the specific saturation volume vi of the highly porous cellulose-peat mixture is 4.18.
If the degree of porosity of an insulating compound is denoted by ro, then by definition is Lyem
EMI0002.0016
For the example given there is
EMI0002.0018
This results in the degree of porosity of the highly porous cellulose-peat mixture as p = 31.9.
Known devices can be used to mix the substances and process them to the end product.
