Description

Verfahren, um aufgelockerten synthetischen Asbest in Wasser quellbar, aufschlämmbar und Rockbarer zu machen Bei dem Verfahren zür Herstellung von synthetischem Asbest nach einem eigenen. nicht vorveröffentlichten Vorschlag werden oxydsilicatische Grundmassen in Gegenwart von N@atriumverbindungen sowie Fluorverbindungen und Wasser auf Temperaturen unterhalb ihrer Schmelzpunkte erhitzt. Diese synthetischen Asbeste können grundsätzlich überall als Austauschstoffe für natürliche Asbeste verwendet weYden. Davon gibt es jedoch einige Ausnahmen, und zwar diejenigen Anwendungsgebiete, wo das Verhalten des natürlichen Asbestes beim Verteilen in Wasser für seine Verwendungsfähigkeit mitbestimmend ist, z. B. die Industrie des Asi-"estz@ements und die Filterindustrie, zum großen Teil auch die Papierindustrie. Dort kann bisher synthetischer Asbest wegen. mangelnder Quellbarkeit, Flockbarkeit und Aufschlämmbarkeit nicht angewendet werden.Process to make loosened synthetic asbestos swellable in water, Slurry and rockable in the process for the production of synthetic Asbestos according to its own. not pre-published proposal will be oxydsilicate Base masses in the presence of sodium compounds as well as fluorine compounds and water heated to temperatures below their melting points. These synthetic asbestos can basically be used anywhere as a substitute for natural asbestos weYden. However, there are a few exceptions to this, namely those areas of application where the behavior of natural asbestos when dispersing in water for its usefulness is co-determining, z. B. the Asian cement industry and the filter industry, to a large extent also the paper industry. So far, synthetic asbestos can be used there because. lack of swellability, flocculability and slurryability not used will.

Das vorliegende Verfahren hat nun zum Ziel, die Anwendungsfähigkeit von synthetischem Asbest für solche und ähnliche Industrien gleich zu machen mit der von natürlichem Asbest. Es hat sich gezeigt, daß man den synthetischen Asbest durch Behandeln mit Seifen beliebigen Anions hockbar, quellbar und aufschlämmbar machen kann, wenn diese bestimmte Kationen enthalten. In Frage kommen als Kation Barium, Cadmium, Strontium, Zink, vorzugsweise Magnesium und Aluminium, insbesondere Calcium. Die Behandlung kann vor oder nach dem Einbringen der Asbestteilchen in das Wasser erfolgen und führt zu trberzügen der Seife auf den Asbestteilen. Dieser Erfolg ist schon deshalb überraschend, weil keineswegs alle kapillaraktiven Stoffe den erfindungsgemäf,en 1?rfolg haben; gerade die am stärksten kapillaraktiven -S-toffe. -,;ersagen, z. B. Saponin und höhere Fettsäuren.The aim of the present method is now the applicability of synthetic asbestos for such and similar industries to do the same that of natural asbestos. It has been shown that one can use synthetic asbestos can be squat, swellable and slurry by treating with soaps of any anion if they contain certain cations. Possible cations Barium, cadmium, strontium, zinc, preferably magnesium and aluminum, in particular Calcium. The treatment can be carried out before or after the asbestos particles are placed in the water takes place and leads to cloudy coatings of the soap on the asbestos parts. This Success is for that reason alone surprising, because by no means all capillary-active ones Substances that are successful according to the invention; especially the most capillary active -S-fabrics. - ,; tell, e.g. B. Saponin and higher fatty acids.

Beispiel Asbest wird mit 60,10 zerkleinerter, etwa, 4oo'oiger Seife gut gemischt und zu der Mischung eine in bezug auf den Asbest etwa ; o'o Calciumacetat :enthaltende wiil:')rige Lösung gegeben. Die Menge des Wassers, welches auf diese Weise als Lösungsmittel für das Calciumsalz zu der Mischung kommt, ist mehr oder «=eisiger gleichgültig, es genügt, wenn die Mischung gut benetzt wird.Example Asbestos is crushed with 60.10, about 4oo'o soap well mixed and to the mixture one with respect to the asbestos approximately; o'o calcium acetate : containing solution is given. The amount of water that is on this Way as a solvent for the calcium salt comes to the mixture is more or less «= Icier indifferent, it is sufficient if the mixture is well moistened.

In manchen Fällen ist es praktisch, folgendermaßen zu arbeiten: Auf den Asbest wird, z. B. durch Wasserdampfdestillation, Fettsäure niedergcschlagen. Dieses so erhaltene Produkt wird nun direkt zur Herstellung von Asbestzement verwendet, wobei es das zur Bildung des Seifenüberzuges notwendige Calcium aus dem Zement bezieht.In some cases it is convenient to work as follows: On the asbestos, e.g. B. by steam distillation, precipitate fatty acid. This product obtained in this way is now used directly for the production of asbestos cement, drawing the calcium necessary for the formation of the soap coating from the cement.
