Abstract
Description
Das Streuen von Salz in Verbindung mit einer Flüssigkeit (Salzlösung, Sole), das auch als "Feuchtsalz-Streuung" bezeichnet wird, ist unter folgenden Aspekten zu sehen:
- – Das Streugut soll auf die Straße ausgebracht werden. Seitliche Fehlwürfe in den Grünstreifen sollten möglichst vermieden werden.
- – Das Streugut sollte möglichst homogen über die Streubreite verteilt sein.
- – Das Mischungsverhältnis von Salz und Sole sollte über der Streubreite in sinnvollen Grenzen homogen sein.
- - The spreading material should be spread onto the road. Lateral misses in the green strips should be avoided as far as possible.
- - The spreading material should be distributed as homogeneously as possible over the spreading width.
- - The mixing ratio of salt and brine should be homogeneous over the range within reasonable limits.
Wenn ein derartiges Anforderungsprofil besteht, muss auch ein Messverfahren zur Verfügung stehen, mit dem eine Überprüfung der Vorgaben zuverlässig möglich ist.If If such a requirement profile exists, a measurement procedure must be used be available, with a review of the Specifications reliable possible is.
In der Vergangenheit wurde hauptsächlich Trockensalz ausgebracht bzw. die Güte der Streugutverteilung mit Trockensalz getestet. Trockensalz lässt sich von einer trockenen Straße mit einem normalen Staubsauger absaugen, auch wenn dies mit Verlusten im Feinkornbereich des Salzes verbunden ist. Bei nassen Straßen, insbesondere bei einer üblichen Rauhigkeit des Asphalts, ist die Wiederfindungsrate für das ausgebrachte Streugut aber selbst bei trockener Ausbringung von Streugut unter Umständen zu gering, insbesondere dann, wenn das Streugut einen erheblichen Feinanteil aufweist.In The past was mainly dry salt applied or the goodness the spreading material distribution with dry salt tested. Dry salt can be from a dry road Vacuum with a normal vacuum cleaner, even if this involves losses in the fine grain area of the salt is connected. On wet roads, in particular at a usual Roughness of the asphalt, the recovery rate for the discharged Spreading material but even with dry spreading of grit under circumstances too low, especially if the grit has a significant Fine fraction has.
Neuerdings wird Trockensalz vor dem Aufbringen auf die Straße mit einer Salzlösung (Sole) versetzt. Das Salz – Sole Gemisch kann in den porösen und rauen Straßenbelag eindringen und ist dann auch durch einfaches Absaugen nicht in ausreichendem Umfange vom Straßenbelag aufzunehmen.recently dry salt is mixed with saline (brine) before application to the road. The salt - brine Mixture can be in the porous and rough road surface penetrate and is then by simple suction not sufficient Scope of the road surface take.
Aus diesem Sachverhalt ergibt sich die Aufgabenstellung für die vorliegende Erfindung.Out This situation results in the task for the present Invention.
Es sollen ein Verfahren und ein Gerät entwickelt werden, mit welchem ausgebrachtes Streugut unterschiedlichster Qualität, insbesondere auch Gemische von Trockensalz und Sole, mit hoher Wiederfindungsrate von Straßen aufgenommen werden können. Die Auswertung der somit gewonnenen Proben soll auf einfache Weise die Salz- und Solemenge je m2 Straßenbelag ergeben.A method and a device are to be developed with which applied spreading material of very different quality, in particular also mixtures of dry salt and brine, can be taken up with a high recovery rate of roads. The evaluation of the samples thus obtained should easily give the salt and brine per m 2 of road surface.

Of the Separate detection of dry salt and brine can be made by use suitable tracer substances with subsequent chemical analysis or by photometry.
