Description
Bei den bekannten Arbeitsweisen zur Herstellung von Bodenverbesserungsmitteln auf Basis von Cellulose oder Lignin unter Zusatz von Alkalisilikat, wie sie beispielsweise in der deutschen Patentschrift 165 976 beschrieben werden, wurde stets in Gegenwart von Wasser gearbeitet, um eine hinreichende Vermischung, leichte Löslichkeit im Boden, oder auch Reaktion mit den üblichen Komponenten zu erreichen. Demgemäß werden in allen diesen Fällen Produkte mit einem relativ hohen Wassergehalt er- to halten, der entweder nachträglich durch Trocknung noch herabgesetzt werden muß, oder aber dazu führt, daß relativ große Mengen Wasser transportiert werden müssen. Bei Verwendung von festen Alkalisilikaten und insbesondere bei Vermischung der Kornponenten in Abwesenheit von Wasser war bisher offensichtlich angenommen worden, daß die Wirksamkeit derartiger Mittel nicht hinreichend ist.In the known working methods for the production of soil improvers based on cellulose or lignin with the addition of alkali metal silicate, such as those in the German patent 165 976 are described, work was always carried out in the presence of water in order to obtain a sufficient Mixing, easy solubility in the soil, or reaction with the usual components to achieve. Accordingly, in all of these cases, products with a relatively high water content are eroded hold, which either has to be reduced afterwards by drying, or it leads to that relatively large amounts of water have to be transported. When using solid alkali silicates and especially when the components are mixed in the absence of water apparently it has been assumed that the effectiveness of such agents is insufficient.
Es wurde jedoch gefunden, daß man bei Anwendung der nach dem nachstehend beschriebenen Verfahren hergestellten Bodenverbesserungs- und Düngemittel zu äußerst wirksamen Produkten gelangt, da diese eine geringere Auswaschbarkeit des Alkalisilikats und somit eine gewisse Depotwirkung entfalten können. Das neue Verfahren zur Herstellung von Bodenverbesserungs- und Düngemitteib aus cellulosehaltigem Fasermaterial und Alkalisilikaten ist dadurch gekennzeichnet, daß die festen Komponenten zusammen mit Alkalisulfaten und/oder Thomasphosphatschlacken und/oder Hochofenschlacken vermahlen werden. Den Produkten können weiterhin gewünschtenfalls Pflanzennährstoffe enthaltende Verbindungen und/oder synthetische strukturstabilisierende Vernetzungsmittel, wie Polyanionen oder PoIykationen hinzugefügt werden.However, it has been found that using the procedure described below Soil improvers and fertilizers produced come to extremely effective products because these develop a lower washability of the alkali silicate and thus a certain depot effect can. The new process for the production of soil improvers and fertilizers from cellulosic Fiber material and alkali silicates is characterized in that the solid components Grind together with alkali sulfates and / or Thomas phosphate slags and / or blast furnace slags will. If desired, compounds containing plant nutrients can also be added to the products and / or synthetic structure-stabilizing crosslinking agents, such as polyanions or polycations to be added.
Neben der bereits erwähnten Depotwirkung haben die neuen Bodenverbesserungsmittel die Eigenschaft, daß sie die Wirkung von synthetischen Kettenkolloiden, soweit deren Anwendung erwünscht ist, so erheblich verstärken, daß deren Wirkung noch bei einer Verminderung der üblichen Anwendungsmenge auf den sechsten Teil festgestellt werden kann. Darüber hinaus ergeben jedoch die neuen Produkte, auch bei Bodenarten ohne Mitwirkung synthetischer Kettenkolloiden, eine starke Krümelvernetzung. In addition to the depot effect already mentioned, the new soil improvers have the property that they have so considerable the effect of synthetic chain colloids, insofar as their use is desired reinforce that their effect is still increased when the usual application amount is reduced the sixth part can be determined. In addition, however, the new products also result in Soil types without the involvement of synthetic chain colloids, a strong crumb network.
Für die Durchführung des Verfahrens werden die nachstehenden Beispiele angeführt:The following examples are given for carrying out the procedure:
1. Natrium- und Kaliumsüikat in Form von Stükkenglas mit und ohne Beifügung von Glasabfällen wird zusammen mit 30 Gewichtsprozent Hüttensilikaten (Hüttenschlacke oder Thomasmehl) sowie 10 bis 30 Gewichtsprozent eines cellulosehaltigen Fasermaterials gemeinsam vermählen. 1. Sodium and potassium silicate in the form of piece glass with and without the addition of glass waste, together with 30 percent by weight of metallurgical silicates (metallurgical slag or Thomas flour) and 10 to 30 percent by weight of a cellulose-containing fiber material are ground together.
2. Ein Mahlgut, wie im Beispiel 1 angeführt, wird mit etwa 10 bis 20 Gewichtsprozent Alkalisulfat versetzt.2. A mill base, as listed in Example 1, is made with about 10 to 20 percent by weight of alkali metal sulfate offset.
In allen Fällen ergeben sich Streumittel mit einem hohen Gehalt an Kolloiden, die zu einer Aggregatbildung in armen Böden mit geringem Kolloidgehalt beitragen.In all cases, grit results with a high content of colloids, which lead to the formation of aggregates in poor soils with a low colloid content.
Es ist bereits aus der deutschen Patentschrift 749795 ein Verfahren zur Herstellung von Düngemitteln bekannt, wobei humifizierte Abwasserklarschlämme oder ähnliche schlammartige Massen mit Wasserglas in Mengen bis zu 5 '/0 versetzt werden. Es handelt sich dabei somit um Produkte mit einem sehr geringen Alkalisilikatanteil, die auf Grund der ganz andersartigen Zusammensetzung nicht mit den erfindungsgemäßen Mitteln vergleichbar sind.It is already from the German patent 749795 a process for the production of fertilizers known, with humified sewage sludge or similar sludge-like masses Water glass can be added in amounts up to 5%. These are therefore products with a very low alkali silicate content, which, due to the very different composition, cannot be used with the Agents according to the invention are comparable.
