Description
Verhinderung der Klumpenbildung bei der Herstellung wässeriger Zubereitungen wasserquellbarer, feinpulveriger, organischer Stoffe Es ist bekannt, daß gelbildende organische Stoffe in feinpulveriger Form bei Quellungs- bzw.Prevention of lump formation in the manufacture of aqueous preparations water-swellable, finely powdered, organic substances It is known that gel-forming organic substances in fine powder form with swelling resp.
Lösungsvorgäugen zur Klumpenbildung neigen.Solution precursors tend to form lumps.
Versuche der Parentinhaberin haben ergeben, daß die Klumpenbildung immer dann auftritt, wenn die Korngröße des Materials eine von der Queldungsgeschwindigkeit abhängige Grenze unterschreitet.Experiments by the parent owner have shown that the clumping always occurs when the grain size of the material is one of the swelling speed falls below dependent limit.
Das Auftreten dieser störenden Klumpen oder Knötchen ist dem Umstande zuzuschreiben, daß ein Teil des Pulvers infolge zu großer Quellungs- bzw.The appearance of these troublesome lumps or nodules is the cause attributable to the fact that part of the powder due to excessive swelling or
Lösungsgeschwindigkeit heim Anrühren mit L& sungsmitteln so schnell zu einem Gel anquillt, daß von diesem Gel andere Teile des Pulvers, die noch nicht oder nur unvollkommen verquolien sind, eingeschlossen werden. Diese Klumpen verquellen entweder überhaupt nicht mehr oder nur sehr schwierig zu einer gleichmäßigen Lösung. Vielfach läßt sich eine gleichmäßige Auflösung dieser Klumpen auch nicht durch längeres Erhitzen berbeiführen, da empfindliche Stoffe, z. B. Pektine, hier- ) Von der Patentsucherin ist als der Erfinder angegeben worden: Dr. Rudolf Georg Schulz, Düsseldorf-Holthausen bei Abbauerscheinungen zeigen, die das ganze Erzeugnis unbrauchbar machen.Dissolving speed when mixed with solvents so fast to a gel swells that of this gel other parts of the powder that have not yet or are only imperfectly quoted, are included. These lumps swell either not at all or very difficult to find a uniform solution. In many cases, these lumps cannot dissolve evenly even after a long period of time Touch heating, as sensitive materials, e.g. B. Pectins, here- ) From the patent seeker has been named as the inventor: Dr. Rudolf Georg Schulz, Düsseldorf-Holthausen at Show signs of degradation which make the entire product unusable.
Es ist daher seit langem üblich, derartige Stoffe nicht in feinpulveriger Form zu verwenden, sonden man war bisher gezwungen, das Feinmaterial auszusieben und nur bestimmte Korn; größen in den Handel zu bringen. Das ausgesiebte Feinmaterial mußte dann erneut aufgelöst und in den Fabrikationsgang zurückgegeben werden. Diese Maßnahme ist natürlich umständlich und bei manchen Stoffen, bei denen durch die wiederholte Auflösung die Gefahr eines hydrolytischen. Abbaues besteht, üblerhaupt nicht durchführbar. It has therefore long been customary not to use finely powdered substances of this type To use form, one was previously forced to sieve out the fine material and only certain grain; to bring sizes into the trade. The sifted out fine material then had to be dissolved again and returned to the factory aisle. These Measure is of course cumbersome and with some substances, with which by the repeated dissolution the risk of a hydrolytic. Dismantling exists, wicked head not feasible.
Es wurde nun gefunden, daß man die Klumpen bildung bei der Herstellung wäßriger Zubereitunr gen was serquellbarer, feinpulveriger organischer Stoffe dadurch verhindern kann, daß man dieselben zuvor zu porösen - gröberen Teilchen verbindet. It has now been found that the formation of lumps during manufacture Aqueous preparations of water-swellable, finely powdered organic substances can prevent that one connects the same previously to porous - coarser particles.
Diese porösen Aggregate bestehen . sozusagen ans kleinen Baldeschwämmchen und zeigen schon durch ihre erhöhte Teilchengröße eine Verringerung der Quellungsgeschwindigkeit.These porous aggregates exist. to the little bald sponge, so to speak and already show a reduction in the rate of swelling due to their increased particle size.
Der Hauptvorzug dieser Aggregate besteht aber darin, daß durch die Kapillarattraktion, deren Größe bekanntlich mit zunehmender Feinheit der Kapillaren wächst, das Lösungsmittel vom äußeren Rande der Teilchen bis in deren Inneres gesaugt und dadurch ein Zusammenkleben der Teilchen zu Klumpen verhindert wird. Auf diese Weise wird also die ganze Masse gleichmäßig durchfeuchtet und eine Verquellung bzw. Lösung zu einem gleich mäßigen Erzeugnis gewährleistet. The main advantage of these units is that the Capillary attraction, the size of which is known to increase with the increasing fineness of the capillaries grows, the solvent is sucked from the outer edge of the particles to the inside and thereby preventing the particles from sticking together to form lumps. To this So the whole mass is evenly moistened and a swelling or swelling Solution to a uniform product guaranteed.
Das der Erfindung zugrunde liegende rein physikalische Prinzip der Verbindung der feinpulverigen Stoffe zu gröberen porösen Teilchen läßt sich nun -auf mehrfache Art durchführen. So kann man die Verbindung der Feinstteilchen durch Behandlung mit quellenden Medien herbeiführen. The purely physical principle underlying the invention The connection of the finely powdered substances to coarser porous particles can now be achieved - Perform in multiple ways. So you can connect the fine particles through Treat with swelling media.
Man kann z. B. die feinpulverigen Stoffe mit ge ringen Mengen eines Lösungsmittels, z. B. etwa 2 bis 3 0/o, anfeuchten, die angefeuchtete Masse zwischein erhitzten Flächen behandeln und die entstandenen Schuppen oder Fladen zu Aggregaten von der: gewünschten Größe zerkleinern. You can z. B. the fine powdery substances with ge wrestling amounts of a Solvent, e.g. B. about 2 to 3 0 / o, moisten, the moistened mass between Treat heated surfaces and turn the resulting flakes or cakes into aggregates of the: desired size.
Ferner kann man die feinpulverigen Stoffe mit -Flüssigkeiten, Flüssigkeitsgemisclìen oder Emulsionen, die für die in Frage kommenden Stoffe ein gewisses Lösungsvermögen besitzen, behandeln und gegebenenfalls die überschüssige Flüssigkeit durch Trocknen entfernens Die beabsichtigte Wirkung kann bei Verwendung gleicher Korngrößen als Ausgangsprodukt noch das durch verbessert werden, daß man den angewende ten Flüssigkeiten Stoffe zusetzt, die durch eine Art Gerbung die Lösungsgeschwindigkeit der Teilchen herabsetzen. Derartige Stoffe sind z. B. Aluminate, Borate, Citrate, Tannine u. dgl. Furthermore, the finely powdered substances can be mixed with liquids and liquids or emulsions that have a certain dissolving power for the substances in question own, treat and optionally remove the excess liquid by drying remove The intended effect can be achieved if the same grain sizes are used as The starting product can still be improved by using the liquids applied Adds substances which, through a kind of tanning, reduce the dissolution rate of the particles reduce. Such substances are z. B. aluminates, borates, citrates, tannins and. like
Die gleiche Wirkung kann man auch durch Zusatz von Stoffen mit einem gewissen Adhäsions-oder Klebevermögen erreichen. The same effect can also be achieved by adding substances with a achieve a certain adhesion or stickiness.
Wenn als Lösungsmittel Wasser oder wasserhaltige Flüssigkeiten verwendet werden, so genügt bei einem bestimmten Wassergehalt auch ein einfaches Sinternlassen des zu feinen Pulvers bei etwas erhöhter Temperatur. If water or liquids containing water are used as solvents a simple sintering is sufficient for a certain water content of the too fine powder at a slightly higher temperature.
Die angegebene Wirkung der Aggregierung kann bei wasserlöslichen oder in Wasser quellbaren Stoffen auch durch Zusatz feinstverteilter hygroskopischer Stoffe zu den feinpulverigen organischen Stoffen erreicht werden, wenn man das Gemenge einer feuchten Atmosphäre aussetzt. Die hygroskopischen Stoffe ziehen Wasser an, wobei gleichzeitig die benachbarten Teilchen zu lockeren porösen Aggregaten verkleben. The stated effect of aggregation can occur in the case of water-soluble or substances that swell in water, also through the addition of finely divided hygroscopic substances Substances to the finely powdered organic substances can be achieved when you add the mixture exposed to a humid atmosphere. The hygroscopic substances attract water, at the same time the neighboring particles stick together to form loose porous aggregates.
Beispiele 1. Ion kg feinstpulverisierter tierischer Leim werden in einem Turm zerstäubt, dabei mit etwa 21/2 1 Wasser in Nebelfofm angefeuchtet und schließlich durch Trocknung wieder auf den ungefähren Wassergehalt des Ausgangsmaterials gebracht. Die aggregierten Leimteilchen lassen sich mit Wasser zu einem klumpenfreien Klebstoff anrühren. Examples 1. Ion kg of finely powdered animal glue are used in atomized in a tower, moistened with about 21/2 l of water in fog and finally by drying again to the approximate water content of the starting material brought. The aggregated glue particles can be mixed with water to form a lump-free one Mix the glue.
Dem zur Befeuchtung des Leims verwendeten Wasser können auch Netzmittel oder Stoffe hinzugesetzt werden, die die Quellungsgeschwindigkeit des Leims in Wasser herabsetzen, so z. B. Wetting agents can also be added to the water used to moisten the glue or substances are added that reduce the rate of swelling of the glue in water reduce, so z. B.
ALuminate, Gerbs,tolffe oder organische Lösungsmittel. Aluminum, tannins, tolffe or organic solvents.
2. In einem Zerstäubungsapparat wird eine kaltgesättigte Gelatinelösung zerstäubt und gleichzeitig durch ein Zuführungsrohr feinstpulveriertes Pektin in die Zerstäubungszone eingeführt. Die aggregierten Pektinteilchen lassen sich mit Wasser zu einem homogenen Erzeugnis anrühren, das z. B. vorteilhaft zur Herstellung von Fruchtgelees verwendet werden kann. 2. In a nebulizer a cold saturated gelatin solution atomized and at the same time finely powdered pectin in introduced the atomization zone. The aggregated pectin particles can be used with Mix water to a homogeneous product, which z. B. advantageous for production Can be used by fruit jellies.
Das neue Verfahren kann in den verschiedensten Industriezweigen, so z. B. bei der Herstellung pharmazeutischer Produkte, Lebensmittel, Waschmittel, Klebstoffe, Appretur- und Schlichtemittel, Farbbindemittel usw., überall dort verwendet werden, wo beim Anrühren feiner Pulver in einem flüssigen .medium die Gefahr der Klumpenbildung besteht. The new process can be used in a wide variety of industries, so z. B. in the manufacture of pharmaceutical products, foodstuffs, detergents, Adhesives, finishing and sizing agents, dye binders, etc., used everywhere be where when mixing fine powder in a liquid .medium the risk of There is lump formation.
Als Ausgangsstoffe für das angemeldete Verfahren können. beispielsweise folgende Stoffe verwendet werden: Seifenpulver, Waschmittel, Saponine, Pflanzenschleime, Leim, Gelatine, Pektine, Pflanzengummistoffe, Stärkepräparate, Dextrine usw. Can be used as starting materials for the registered procedure. for example the following substances are used: soap powder, detergents, saponins, plant slimes, Glue, gelatine, pectins, vegetable gums, starch preparations, dextrins, etc.
Zum erfindungsgemäßen Behandeln mit Wasser wird das handelsübliche, also das bereits befeuchtete Dextrin verwendet (vgl. Ullmann, »Enzyklopädie der technischen Chemie«, I929, 'Bd.-3, S.634 und 636). UIlmann weist darauf hin, daß das Befeuchten des Dextrins unter Einhaltung gewisser Vorsichtsmaßnahmen (strenges Achten darauf, daß keine Wassertröpfchen auf das Dextrin fallen) zu erfolgen hat, um Grießbildung zu vermeiden. Demgegenüber wird nun. aber erfindungsgemäß auf die Erzielung badeschwammähnlicher, agglomerierter Dextrinteilchen hingearbeitet, wobei das Dextrin direkt mit geringen Mengen, etwa 2 bis 3 O/o Wasser behandelt wird und anschließend ohne Anwendung von Druck getrocknet wird. For treatment according to the invention with water, the commercially available, So the already moistened dextrin is used (cf. Ullmann, »Enzyklopädie der Technical Chemistry, 1929, Vol. 3, pages 634 and 636). UIlmann points out that the moistening of the dextrin while observing certain precautionary measures (strict Make sure that no water droplets fall on the dextrin), to avoid grit formation. In contrast, now. but according to the invention on the Achievement of bath sponge-like, agglomerated dextrin particles worked towards the dextrin is treated directly with small amounts, about 2 to 3 O / o of water and is then dried without applying pressure.
Das neue Verfahren läßt sich selbstverständlich sowohl kontinuierlich als auch diskontinuierlich durchführen. The new process can of course be carried out continuously as well as discontinuously.
