Abstract
Description
"Verfahrung zur Herstellung harnstoffhaltiger Klebmittel für Granulierungs- und Bodenverbesserungszwecke." Beschreibung."Process for the production of urea-containing adhesives for granulation and soil improvement purposes. " Description.
nur Granulierung von Düngemitteln sind beispielsweise biochemische Silikate oder organische Iiaftmittel verschiedener Art verwendet worden und bekannt.Diese Mittel tragen zu einer Auerichtung der Eigenschaften von Mineraldüngemitteln auf bodenverbessernde --unktionen nicht bei.Allgemein enthalten sie auch keinen nennenswerten Prozentsatz an einem der nauptnähretoffe für Pflanzen.For example, only granulation of fertilizers are biochemical Silicates or organic solvents of various kinds have been used and known. These Means apply to an alignment of the properties of mineral fertilizers Soil-improving functions are not included, and in general they do not contain any noteworthy Percentage of one of the main nutrients for plants.
Nach dem erfindungsgemäßen Verfahren wird dagegen ein Mittel vorgeschlagen, das nicht nur Stickstoff enthält, sondern dessen Komponenten auch zur Vernetzung von Bodenkrümeln beitragen.According to the method according to the invention, however, a means is proposed which not only contains nitrogen, but also its components for crosslinking of soil crumbs contribute.
Die Komponenten des neuen mittels sind feinkristalliner Harnstoff,Alkalicellulose und gegebenenfalls neben methylierter Alkalicellulose andere Methylverbindungen.The components of the new means are finely crystalline urea, alkali cellulose and optionally other methyl compounds in addition to methylated alkali cellulose.
Da die durch Einwirkung von Methylverbindungen auf Alkalicellulose entstehenden Mittel als leicht erhältliche Industrieprodukte bekannt sind, wie zum Beispiel das Produkt Relatin der Henkelwerke in Düsseldorf,geht man bei der Herstellung der erfindungsgemäßen Klebmittel zwecmäßigerweise von einer derartigen Methylcellulose und Harnstoff aus.Because the by the action of methyl compounds on alkali cellulose emerging funds are known as readily available industrial products, such as for For example, the product Relatin from Henkelwerke in Düsseldorf, if you go to the manufacturing process the adhesive according to the invention expediently from such a methyl cellulose and urea.
Bei der Ermittlung der zweckmäßigen Größe polymerer Agglomerate aus diesen Stoffen, die für die funktionellen Eigenschaften der Teilchen in den Agglomeraten bei Wiedereintritt von Wasser beziehungsweise bei weiterem Eintritt von Wasser in die Mischstrukturen oder Zwillings-Strukturen von Bedeutung ist,andererseits durch technische Faktoren bei der Anwendung und erteilung bestimmt ist,wurde gefunden,daB zum Beispiel Anteilmengen von fethylalkohol,die der Mischung M CH2- und OH- zuführen und zwar über die zur Methylierung der Cellulose notwendige enge dieser Gruppen hinaus, dazu beitragen, die erwünschte (kleinere) Agglomeratgröße zu erzielen.When determining the appropriate size of polymeric agglomerates these substances that are responsible for the functional properties of the particles in the agglomerates with re-entry of water or with further entry of water in the mixed structures or twin structures is important, on the other hand by technical factors in the application and issue, it was found that For example, proportions of ethyl alcohol that add CH2- and OH- to the mixture M namely about the close range of these groups necessary for the methylation of cellulose also help to achieve the desired (smaller) agglomerate size.
Die erfindungsgemäßen mittel können beispielsweise wie folgt hergestellt werden: Beispiel 1.The agents according to the invention can be produced, for example, as follows become: Example 1.
Gleiche Gewichtsteile feinkristallinen Harnstoffs und von Methylcellulose werden trocken sorgfältig vermischt und am Schluss des Mischvorganges noch während der drehung des Gerätes leicht mit Wasser besprüht.Equal parts by weight of fine crystalline urea and methyl cellulose are carefully mixed dry and at the end of the mixing process still during the rotation of the device lightly sprayed with water.
Beispiel 2.Example 2.
Gleiche Gewichtsteile Harnstoffs und von ethylcellulose werden trocken sorgfältig vermischt und am chluss des xischvorganges leicht mit Methylalkohol besprüht.Equal parts by weight of urea and ethyl cellulose become dry mixed carefully and lightly sprayed with methyl alcohol at the end of the mixing process.
Beispiel 3.Example 3.
Drei Gewichtsteile an narnstoff und zwei Gewichtsteile an Methylcellulose werden mit zwei Zehntel Gewichtsteilen bezogen auf oblige 5 ganze Gewichtsteile) an Zinkacetat versetzt und sorgfältig vermischt.Am Schluss des Mischvorganges wird das im wischer befindliche Produkt noch während des Drehvorganges mit Methylalkohol leicht bespraht.Three parts by weight of urea and two parts by weight of methyl cellulose are with two tenths parts by weight based on the required 5 whole parts by weight) Zinc acetate added and carefully mixed. At the end of the mixing process, the product in the wiper with methyl alcohol during the turning process easily spotted.
Bereits beim Vorgehen nach eispiel 1 bleibt in dem Mischprodukt die bekannte Kristallisierung des izarnstoffs in lanen Nadeln aus, wie vom Erfinder durch Mikrofoto nachgewiesen.Neben den auffallenden Cellulosesträngen befinden sich nach Ausreagieren des Systems in diesem nur rormen, die einerseits an die bildungen amorpher Körper in solloidsuspensionen erinnern una andererseits deutlich die Zähigkeit zur verknüpfung oder Vernetzung größerer .ineralteilchen erkennen lassen.Even when proceeding according to example 1, the known crystallization of izarnea in lane needles, as described by the inventor proven by microfoto. In addition to the conspicuous strands of cellulose are After the system has fully responded to this only rorms, on the one hand to the education amorphous bodies in solloid suspensions are clearly reminiscent of the toughness on the other hand to link or cross-link larger mineral particles.
werden mineralische Teilchen mit einem der beschriebenen Mittel verklebt oder agglomerSiert,so ist eine Weitergabe ihrer unktionseigenschaften an andere Teilchen oder Koagulate ermöglicht.mineral particles are bonded with one of the agents described or agglomerated, their functional properties are passed on to others Particles or coagulates possible.
