Abstract
Description
Die vorliegende Erfindung betrifft Partikel zur Bildung eines Bodens.The The present invention relates to particles for forming a soil.
Üblicherweise werden Bodenbeläge in einem Aquarium durch Sand oder Kies gebildet. In einem derartigen Bodenbelag wurzeln die in das Aquarium eingesetzten Pflanzen. Ein Problem eines derartigen Bodenbelages besteht darin, dass sich an ihm sehr schnall Algen ausbilden, sodass er relativ schnell gereinigt bzw. ersetzt werden muss. Dies bedeutet aber einen Eingriff in das Aquarium, der für die Bewohner desselben nachteilig ist.Usually be flooring formed in an aquarium by sand or gravel. In such a Flooring is rooted in the plants used in the aquarium. One Problem of such a floor covering is that to him training algae very quickly so that it is cleaned relatively quickly or must be replaced. But this means an intervention in the Aquarium for the inhabitants of the same is disadvantageous.

Die Aufgabe der vorliegendem Erfindung besteht darin, Partikel zu schaffen, die selbst den Boden eines Aquariums oder eines Pflanzengefäßes so gestalten, dass ein ausgezeichnetes Pflanzenwachstum bewirkt wird.The The object of the present invention is to provide particles who shape the bottom of an aquarium or a planter that an excellent plant growth is effected.
Diese Aufgabe wird durch Partikel zur Bildung eines Bodens mit den Merkmalen des Patentanspruches 1 gelöst.These Task is by particles to form a soil with the characteristics of claim 1.
Der wesentliche Vorteil der vorliegenden Erfindung besteht darin, dass bei der Verwendung in einem Aquarium die Teilchengröße der erfindungsgemäßen Partikel so groß gewählt ist, dass die Partikel selbst als Bodenbelag in ein Aquarium eingebracht werden können. Eine umständliche Zumischung von Zeolithpulver zu einem aus Sand oder Kies bestehenden Bodenbelag ist daher nicht erforderlich. Ein weiterer wesentlicher Vorteil einer Weiterbildung der vorliegenden Erfindung besteht darin, dass die den Bodenbelag bildenden Zeolith-Partikel auch eingefärbt sein können, sodass in einem Aquarium durch eine gezielte farbige Ausgestaltung des Bodenbelages bestimmte ästhetische und dekorative Wirkungen sowie ggf. auch eine Anpassung an den natürlichen Lebensraum bestimmter Aquarienbewohner erzielbar sind. Vorteilhafterweise wird das Algenwachstum im Aquarium wirksam verlangsamt bzw. unterbunden. Vorteilhafte Verfahren zur Herstellung der erfindungsgemäßen, eingefärbten Zeolith-Partikel gehen aus den Unteransprüchen 7 bis 12 hervor.Of the The essential advantage of the present invention is that when used in an aquarium, the particle size of the particles according to the invention is chosen so big that the particles themselves are introduced as a floor covering in an aquarium can. A complicated one Admixture of zeolite powder to one consisting of sand or gravel Flooring is therefore not required. Another essential Advantage of a development of the present invention is that the zeolite particles forming the floor covering are also colored can, so in an aquarium by a purposeful colored design of the flooring certain aesthetic and decorative effects as well as possibly an adaptation to the natural Habitat of certain aquarium inhabitants are achievable. advantageously, Algae growth in the aquarium is effectively slowed down or prevented. Advantageous processes for the preparation of the dyed zeolite particles according to the invention go from the dependent claims 7 to 12.
Bei der Verwendung der erfindungsgemäßen Partikel in einem Pflanzgefäß besteht der wesentliche Vorteil darin, dass der dekorative Wert von Pflanzengefäßen dadurch wesentlich erhöht wird, dass ein durchsichtiges Pflanzengefäß, beispielsweise ein aus Glas bestehender Blumentopf, verwendet wird, wobei in das durchsichtige Pflanzengefäß ein gefärbtes Pflanzsubstrat, bei den es sich vorzugsweise um einen saugfähigen Spezialstein in Kies- oder Granulatform handelt, eingebracht wird. Da das Pflanzengefäß aus einem durchsichtigen Material besteht, tritt das farbige Pflanzsubstrat optisch deutlich in Erscheinung, wodurch eine besondere dekorative Wirkung erzielt wird. Die Farbe des Pflanzsubstrates kann dabei auf die Art, z.B. die Blütenfarbe, der in dem Pflanzengefäß enthaltenen Pflanze abgestimmt oder an die jeweilige Umgebung des Pflanzengefäßes angepasst werden.at the use of the particles according to the invention in a planter the main advantage in that the decorative value of plant pots thereby significantly increased is that a transparent plant vessel, such as a glass existing flowerpot, being used in the transparent Plant vessel a colored plant substrate, which are preferably an absorbent special stone in gravel or granular form is introduced. Since the plant vessel from a transparent material, the colored plant substrate occurs visually distinct in appearance, creating a special decorative Effect is achieved. The color of the plant substrate can be in the way, e.g. the flower color, the one contained in the plant vessel Plant adapted or adapted to the particular environment of the plant vessel become.
Vorteilhafterweise speichert das aus den vorliegenden Partikeln bestehende, eingefärbte Pflanzsubstrat ebenso wie an sich bekannte Hydrokultur-Substrate Wasser und Nährstoffe für die in den vorliegenden Pflanzengefäßen enthaltenen Pflanzen, sodass diese nicht täglich gegossen werden müssen. Das vorliegende Pflanzsubstrat gibt an die in den Pflanzengefäßen enthaltenen Pflanzen Wasser ab und wirkt nachhaltig als Katalysator, sodass Schadstoffe in kurzer Zeit in harmlose Bestandteile, wie z.B. Wasser und Kohlendioxid, zerlegt werden. Beispielsweise kann das vorliegende Pflanzsubstrat chlorierte und aromatische Kohlenwasserstoffe, Formaldehyd, Triethylenamin, Benzol, Dodecene, sowie aus Zigarettenrauch, Lacken, Reiniger, Kleber, Schaumstoff, Lösungsmittel und Teppichböden stammende Schadstoffe zerlegen.advantageously, stores the existing from the particles present, colored plant substrate as well as known hydroponic substrates water and nutrients for the contained in the present plant vessels Do not plant them daily must be poured. The present plant substrate gives to those contained in the plant vessels Plant water and acts as a catalyst sustainably, so pollutants in a short time into harmless ingredients, e.g. Water and carbon dioxide, be disassembled. For example, the present plant substrate may be chlorinated and aromatic hydrocarbons, formaldehyde, triethyleneamine, Benzene, dodecene, as well as cigarette smoke, varnish, cleaner, glue, foam, solvent and carpets disassemble originating pollutants.
Da sich das in dem durchsichtigen Pflanzengefäß enthaltene, eingefärbte Pflanzsubstrat beim Eingießen von Wasser dunkler färbt, muss erst dann gegossen werden, wenn das feuchte Pflanzsubstrat wieder seine ursprüngliche Farbe angenommen hat. Auf diese Weise kann das vorliegende Pflanzsubstrat vorteilhaft als Anzeigemittel zur Anzeige für das Vorhandensein von für die Pflanzen ausreichenden Wassermengen verwendet werden. Alternativ können aber auch die von der Hydrokultur her bekannten Wasserstandsanzeiger verwendet werden. Das vorliegende Pflanzsubstrat kann bei Verschmutzungen mit lauwarmem Wasser gereinigt werden, sodass es wieder seine ursprüngliche Farbe erhält.There the colored plant substrate contained in the transparent plant container when pouring darker of water, must be poured only when the wet plant substrate again his original Color has accepted. In this way, the present plant substrate can be advantageous as display means for display for the presence of for the plants are used sufficient amounts of water. alternative can but also known from the hydroponic ago water level indicator be used. The present plant substrate may be contaminated with lukewarm water to be cleaned so that it returns to its original state Color gets.
Vorteilhafte Verfahren zur Herstellung der erfindungsgemäßen, eingefärbten Zeolith-Partikel gehen aus Unteransprüchen hervor.advantageous Process for the preparation of the colored zeolite particles according to the invention go from subclaims out.
