Description

Emulsionen zum Schönen von Braunkohlenbriketts Das Patent 656 634 betrifft ein Verfahren zum Schönen von Braunkohlenbriketts, das darin besteht, daß ihre Oberfläche mit rasch brechenden, alkalischen, wäßrigen Emulsionen bituminöser Stoffe versehen wird.Emulsions for enhancing brown coal briquettes Patent 656 634 relates to a method for finishing brown coal briquettes, which consists in that their surface is bituminous with rapidly breaking, alkaline, aqueous emulsions Substances is provided.

Es hat sich nun gezeigt, daß für das Schönen von Braunkohlenbriketts Emulsionen um so weniger geeignet sind, je weniger leicht sie bei Berührung mit der Oberfläche brechen. Es wurde gefunden, daß es möglich ist, haltbare Emulsionen herzustellen, Emulsionen also, die man auf Vorrat lagern und auch zum Versand bringen kann und welche trotz ihrer Beständigkeit gegen äußere mechanische Einwirkung beim Auftragen auf die Oberfläche der Briketts schnell genug brechen, um das Verfahren nach Patent 656 63¢ wirtschaftlich durchführen zu können. Dies wird erfindungsgemäß dadurch erreicht, daß man die im Patent 656 634 beschriebenen Emulsionen nach der Verdünnung des versandfähigen Konzentrates für die Verwendung homogenisiert. Die durch das Homogenisieren stabilisierten Emulsionen brechen nun trotz ihrer sonstigen Beständigkeit überraschenderweise schnell genug, um den Forderungen, die an eine zum Schönen von Braunkohlenbriketts verwendbare Emulsion gestellt werden, zu genügen. Solche Emulsionen besitzen einerseits genügend Stabilität, um durch den stets sich bildenden Kohlenstaub und Kohlengrus sowie durch die in Lösung gehenden Huminsäuren nicht geflockt zu werden, und brechen andererseits trotz dieser Bestandteile rasch genug, damit das fortlaufend durchgeführte Schönungsverfahren wirtschaftlich mit genügender Geschwindigkeit durchgeführt werden kann.It has now been shown that for the beauty of brown coal briquettes The less light they come into contact with, the less suitable emulsions are break the surface. It has been found that it is possible to produce long-lasting emulsions to produce emulsions that are stored in stock and also shipped can and which despite their resistance to external mechanical impact Applying it to the surface of the briquette quickly enough to break the process according to patent 656 63 ¢ to be able to carry out economically. This is according to the invention achieved by the emulsions described in Patent 656,634 according to the Dilution of the dispatchable concentrate homogenized for use. the Emulsions stabilized by the homogenization now break despite their other emulsions Persistence is surprisingly quick enough to meet the demands placed on a emulsion that can be used to beautify lignite briquettes are sufficient. Such emulsions have, on the one hand, sufficient stability to always get through the forming coal dust and coal grit as well as the dissolving humic acids not to be flocculated and, on the other hand, break quickly in spite of these components enough that the continuously carried out fining process is economical sufficient speed can be carried out.
