Description

Formling für Wärmeschutzpackungen Formlinge für Wärmeschutzpackungen sind in der verschiedensten Form bekannt, insbesondere aus Gemischen von basischem Magnesiumcarbonat und Ho asern. Die Masse aus basischem Magnesiumcarbonat bedarf an sich für ein - gutes Zusammenhalten noch einer Unterstützung, die ihr eine größere Festigkeit gibt, wie beispielsweise der Holzschliff nach dem Patent 6oz 218 es bereits tut. Man hat zwar schon vorgeschlagen, für Sorelzementmischungen Holzwollfasern zu verwenden, jedoch spielt hier die Holzfaser eine ganz andere Rolle, denn beim Sorelzement gibt bereits die Mischung als solche eine durchaus feste Bindung und bedarf an sich für den Zusammenhalt nicht der langen Holzfaser, die bei der bekannten Masse den Hauptbestandteil bildet. Auch andere Vorveröffentlichungen, in denen Holzfasern oder Holzfaserpackungen einen Bestandteil bilden, enthalten diesen Teil immer in derartigen Mengen, daß dabei der Holzbestandteil das eigentliche Isoliermittel bildet, während demgegenüber bei dem Erfindungsg°genstand das basische Magnesiumcarbonat den wesentlichen Bestandteil der Isolierung bildet und der Zusatz von feiner Holzwolle als Faserstoff in Gewichtsmengen von 2 bis 50/, der Gesamtmasse erfolgt und nur den Zweck hat und bei der geringen Gewichtsmenge auch nur haben kann, den aus basischem Magnesiumcarbonat bestehenden Isolierstoff vor dem Zerbröckeln besser zu schützen und ein besseres Zusammenhalten des ganzen Formlings für die Wärmeschutzpackungen zu sichern.Moldings for heat protection packs Moldings for heat protection packs are known in a wide variety of forms, in particular from mixtures of basic magnesium carbonate and Ho asers. The mass of basic magnesium carbonate itself needs support to hold it together well, which gives it greater strength, as is already the case with wood pulp according to patent 6oz 218. It has already been proposed to use wood wool fibers for Sorel cement mixtures, but the wood fiber plays a completely different role here, because with Sorel cement the mixture itself provides a firm bond and does not require the long wood fiber that is required for cohesion known mass forms the main ingredient. Other prior publications, in which wood fibers or wood fiber packings form a component, always contain this part in such amounts that the wood component forms the actual insulating agent, while in the object of the invention the basic magnesium carbonate forms the essential component of the insulation and the addition of fine wood wool as fibrous material in amounts by weight of 2 to 50 /, the total mass and only has the purpose and with the small amount of weight also can only have to better protect the insulating material consisting of basic magnesium carbonate from crumbling and to better hold the whole molding together for to secure the heat protection packs.

Erfindungsgemäß wird zweckmäßig die parallel zur Faser gewonnene Holzwolle benutzt, die nicht nur eine erhebliche Elastizität, sondern auch eine hohe mechanische Festigkeit für den Formling vermittelt. Die Herstellung, dies Wärmeschutzkörpers selbst geschieht nach den bekannten Verfahren zur Erzeugung von Magnesiuincarbonaterzeugnissen. Man erreicht so in wärmetechnischer Hinsicht und bezüglich des Gewichtes und Preises ein vorteilhaftes und den bisher bekannten Erzeugnissen überlegenes Erzeugnis, das glimmsicher, gut schalldämpfend ist und die Herstellung in jeder beliebigen Form gestattet.According to the invention, the wood wool obtained parallel to the fiber is expedient used, which not only have a considerable elasticity, but also a high mechanical Conveyed strength for the molding. The manufacture, this heat protection body itself takes place according to the known processes for the production of Magnesiuincarbonaterzeugnisse. This is achieved in terms of thermal technology and in terms of weight and price an advantageous product superior to previously known products, which It is smolder-proof, has good sound-absorbing properties and can be manufactured in any form allowed.
