Description
wie folgt definiert ist:is defined as follows:
_ 2ab a + ο _ 2ab a + ο
Die Werte für a und b sind meßbare Größen. Es ergibt sich daraus ein reproduzierbarer Parameter.The values for a and b are measurable quantities. This results in a reproducible parameter.
Das-Produkt nach dieser Druckschrift bildet erst dann dielektrische Eigenschaften, wenn ein extrem dünner ι ο Film durch Trocknung der aufgebrachten, dünnen Suspension von 5 bis 10% Feststoff erzeugt istThe product according to this publication only forms dielectric properties when an extremely thin ι ο Film is produced by drying the applied, thin suspension of 5 to 10% solids
Für andere Anwendungsgebiete, wie für Trägerstoffe oder für die Herstellung von Fonnkörpern oder Feuerfestmassen, ist dieses Produkt nicht geeignet ι s For other applications, such as for vehicles or for the production of Fonnkörpern or refractory materials, this product is not suitable ι s
Dies liegt daran, daß eine Trocknung in der Masse wegen der extremen Feinteiligkeit und des damit verbundenen Staubens nicht möglich ist in einem wirtschaftlichen Verfahren.This is because there is a drying in bulk because of the extremely fine division and the associated dust is not possible in one economic procedure.
Die britische Patentschrift 11 19 305 lehrt die Herstellung eines extrem feinen Vermiculite durch Aufquellen mit Lithiumsalzen. Diese Salze sind sehr teuer und daher unwirtschaftlich. Dieser Vorschlag entspricht damit dem der britischen Patentschrift 1016 385, der Verwendung von stark das Gitter aufspaltenden Mitteln. Es soll eine 20%ige wäßrige Lösung von LiCl für 24 h angewendet werden. Nach dieser Behandlung soll ebenfalls ein mehrstufiger Waschprozeß mit Zwischenstufen zur Abzentrifugierung der Waschwässer durchgeführt werden. Dieser jo Energieaufwand für Zentrifugen ist erheblich. Wie die dünnen Waschwässer zu beseitigen oder zu konzentrieren sind, wird nicht offenbart Eine Eindampfung wäre völlig unwirtschaftlich. Dieser Vorschlag geht somit nicht über die Lehre der britischen Patentschrift 1016 385 hinaus. Es handelt sich ebenso um einen Laborvorschlag ohne die Möglichkeit einer technischen Realisierung. Die Zerkleinerung des aufgequollenen Materials soll gerade nicht durch »strukturschonende, mechanische Vermahlung« erfolgen. Es soll eine extreme Feinheit durch Zermahlung in Kolloidmühlen erfolgen. Diese Vermahlung soll in einer wäßrigen Suspension mit 1 bis 10% Feststoff erfolgen. Dabei sollen Rockungsmittel zugesetzt werden.British Patent 11 19 305 teaches the Production of an extremely fine vermiculite by swelling with lithium salts. These salts are very expensive and therefore uneconomical. This proposal corresponds to that of the British patent specification 1016 385, the use of strongly splitting agents. It should be a 20% aqueous Solution of LiCl can be applied for 24 h. This treatment should also be followed by a multi-stage Washing process can be carried out with intermediate stages for centrifuging off the washing water. This jo The energy expenditure for centrifuges is considerable. How the thin washing waters are to be removed or concentrated is not disclosed. An evaporation would be completely uneconomical. This proposal therefore does not go beyond the teaching of the British patent specification 1016 385. It is also a laboratory proposal without the possibility of a technical one Realization. The shredding of the swollen material should not be done by »structure-friendly, mechanical grinding «. It is said to be extremely fineness by grinding in colloid mills take place. This grinding should take place in an aqueous suspension with 1 to 10% solids. Included rocking agents should be added.
Dieser Vorschlag der Herstellung eines extrem feinen Produktes geht gerade in eine andere Richtung und führt nicht zu den Parametern des Dreischichtminerals der Erfindung mit einer Dicke von 0,5 bis 10 Mikron.This suggestion of producing an extremely fine product goes in a different direction and does not result in the parameters of the three-layer mineral of the invention having a thickness of 0.5 to 10 microns.
Diese kolloid-feine Suspension soll als Pulpe zur Herstellung von feuerbeständigem Papier verwendet werden. Eine Trocknung dieses wäßrigen Gemisches ist im technischen Maßstab nicht wirtschaftlich. Die Verwendung für andere Anwendungsgebiete entfällt somitThis colloid-fine suspension is said to be used as pulp for the production of fire-resistant paper will. Drying this aqueous mixture is not economical on an industrial scale. the It is therefore not used for other areas of application
Es ist Aufgabe der Erfindung, ein reversibel quellbares, großflächig kristallin ausgebildetes Dreischichtr/iineral mit voneinander gelösten Kristallschichten und mit starken Adhäsions- und Kohäsionskräften herzustellen und ein Verfahren zu seiner Herstellung zur Verfügung zu stellen. Die Lösung dieser Aufgabe ist in den Patentansprüchen 1 und 2 definiert Diese führt zur Herstellung gleichmäßig ebener tafelförmiger Teilchen, wobei über 50 Gewichtsprozent tafelförmige gleichmäßig ebene Teilchen einer Dicke von 0,5 bis 10 Mikron sind, die einen äquivalenten Durchmesser von 10 bis 200 Mikron besitzen und deren Verhältnis Teilchendicke zu äquivalentem Durchmesser gleich oder kleiner 1 :10 istThe object of the invention is to provide a reversibly swellable, large-area crystalline three-layer mineral with crystal layers detached from one another and with strong adhesive and cohesive forces to produce and to provide a method for its production. The solution to this problem is defined in claims 1 and 2 This leads to the production of evenly flat tabular Particles, with over 50 percent by weight tabular uniformly planar particles 0.5 to 10 in thickness Microns, which have an equivalent diameter of 10 to 200 microns, and their ratio Particle thickness to equivalent diameter is equal to or less than 1:10
Es wurde überraschend gefunden, daß nur mit Wasser aufgequollener Vermiculit oder Hydroglimmer durch strukturschonende Zerkleinerung auf diese aufgefundenen Dimensionen zu einem Dreischichtmineral mit starken Adhäsions- und Kohäsionskräften führtIt has surprisingly been found that only vermiculite or hydro mica swollen with water through structure-friendly shredding to these discovered dimensions to form a three-layer mineral strong adhesive and cohesive forces
Das Dreischichtmineral gemäß der Erfindung wird vorzugsweise auch in expandierter Form angewendetThe three-layer mineral according to the invention is preferably also used in expanded form
Der Patentanspruch 3 beansprucht bevorzugte Möglichkeiten zur Anwendung des erfindungsgemäßen Dreischichtminerals.Claim 3 claims preferred options for using the invention Three-layer mineral.
Das Dreischichtmineral gemäß der Erfindung weist gegenüber bekannten Stoffen technische Vorteile auf.The three-layer mineral according to the invention has technical advantages over known substances.
Ein technischer Vorteil ergibt sich beispielsweise für die Verwendung als Bindemittel zusammen mit anderen Wirkstoffen, die in einer, solchen Mischung starke Haftfähigkeit besitzen bei großer spezifischer Oberfläche von etwa 12 mVg.A technical advantage arises, for example, for use as a binder together with others Active ingredients that have strong adhesiveness in such a mixture with a large specific surface area of about 12 mVg.
Der mineralische Stoff gemäß der Erfindung ist somit bevorzugt als Trägerstoff für verschiedene, in der Technik bekannte Anwendungsgebiete geeignet. Dazu gehört auch das Aufbringen von Pflanzenschutzmitteln.The mineral substance according to the invention is thus preferred as a carrier for various, in the Technique known areas of application suitable. This also includes the application of pesticides.
Ein anderes Anwendungsgebiet liegt in der Verwendung als Feuerfestmasse. Der Sinterpunkt des mineralischen Stoffes gemäß der Erfindung liegt bei etwa 1260° C und der Schmelzpunkt bei etwa 1350° C.Another area of application is its use as a refractory material. The sintering point of the mineral substance according to the invention is approximately 1260 ° C and the melting point at around 1350 ° C.
Wichtige Anwendungsgebiete liegen auch in der Verwendung von Körpern und Filmen aus diesem nicht brennbaren Dreischichtmineral gemäß der Erfindung.There are also no important areas of application in the use of bodies and films made from them combustible three-layer mineral according to the invention.
