Abstract

Melting agent for ice and smooth snow areas is based on substances (I) lowering the m.pt., i.e. MgCl2 and/or CaCl2, and mechanical neutralising agent (II), (II) being a porous material with (I) embedded in its pores. Pref. (II) consists of pumice or Ca silicate. The agent can also contain a dyestuff, corrosion inhibitor and artificial fertiliser and/or other plant nutrients. Although (I) are very hygroscopic, (II) prevents caking. The effect of the agent is extended, since (I) are released slowly. MgCl2 is nontoxic and chemically neutral. The amt. of (I) needed is less than with NaCl and (I) cause less corrosion and environmental pollution.

Description

Streumittel für eis- und schneeglatte Flächen Grit for ice and snow-smooth surfaces

Die vorliegende Erfindung bezieht sich auf ein Streumittel für eis- und schneeglatte Flächen auf der Basis von schmelzpunkterniedrigenden Stoffen, nämlich Magnesiumchlorid und/oder Calciumchlorid und mechanisch abstumpfenden Stoffen.The present invention relates to a grit for ice and snow-smooth surfaces based on melting point depressants, namely Magnesium chloride and / or calcium chloride and mechanically deadening substances.

Es ist bekannt, Streumittel zu verwenden, die aus einem Gemisch von mechanisch abstumpfenden Stoffen wie beispielsweise Sand, Holzspänen, Asche oder Torf und Kochsalz (Natriumchlorid) als Schmelzpunkterniedrigendem Stoff bestehen. Diese Streumittel sind bekannt dafür, daß sie eine schädigende Wirkung auf die Vegetation haben, ebenso sind diese Streumittel bekannt für ihre allgemeinen schädlichen Eigenschaften, es sei hier nur stellvertretend auf die Korrision von Metallen hingewiesen.It is known to use grit, which consists of a mixture of mechanically deadening substances such as sand, wood chips, ash or Peat and table salt (sodium chloride) exist as a substance that lowers the melting point. These grit are known to have a damaging effect on vegetation these grit are also known for their general harmful properties, the corrosion of metals is only mentioned here as a representative example.

Außerdem ist die Wirkung des Kochsalzes als schmelzpunkterniedrigendem Mittel bei extrem tiefen Temperaturen nicht mehr gewährleistet.In addition, the effect of table salt is as a melting point lowering Medium is no longer guaranteed at extremely low temperatures.

Es ist auch bekannt, als Auftaumittel Magnesiumchlorid oder Calciumchlorid oder eine Kombination dieser beiden Stoffe zu verwenden, gegebenenfalls auch unter Zusatz von mechanisch abstumpfenden Stoffen.It is also known as a de-icing agent, magnesium chloride or calcium chloride or to use a combination of these two substances, if necessary also under Addition of mechanically deadening substances.

Es hat sich allerdings gezeigt, daß aufgrund der Tatsache, daß Magnesiumchlorid oder Calciumchlorid sehr stark hygroskopisch sind, der praktische Einsatz derartiger Streumittel erhebliche Probleme mit sich gebracht hat, da die Schmelzpunkterriedrigenden Substanzen zu Verklumpungen neigen.However, it has been shown that due to the fact that magnesium chloride or calcium chloride are very hygroscopic, the practical use of such Litter has brought significant problems, since the melting point lowering Substances tend to clump.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Streumittel der eingangs erwähnten Art, welches Magnesiumchlorid und/oder Calciumchlorid enthält, zu entwickeln, welches nicht mehr zu Verklumpungen neigt.The present invention is based on the object of a scattering means of the type mentioned at the beginning, which contains magnesium chloride and / or calcium chloride, to develop which no longer tends to clump.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß der mechanisch abstumpfende Stoff ein poröses Material ist, in dessen Poren der oder die schmelzpunkterniedrigenden Materialien eingebettet sind.The solution to this problem is according to the invention that the mechanically dulling substance is a porous material, in whose pores the one or more melting point lowering Materials are embedded.

Durch diese Maßnahme wird erreicht, daß eine hohe Adsorptionsstabilität der an sich hygroskopischen Materialien erzielt und somit ein Verklumpen des Streumittels verhindert wird. Außerdem stellt sich bei einem derartigen Streumittel eine gewisse Depotwirkung ein, das heißt, ein Teil des Itagnesiumchlorids und/oder des Calciumchlorids steht sofort zum Aufteuen zur Verfügung, während ein weiterer Teil der vorgenannten Stoffe vorerst noch in den Poren des mechanisch abstumpfenden Materiales gelagert bleibt und erst langsam aus diesen Poren herausgelöst wird. Dadurch wird die Wirkung des Streumittels verlängert.This measure ensures that high adsorption stability which achieves hygroscopic materials and thus clumping of the grit is prevented. In addition, there is a certain amount of spreading material of this type A depot effect, that is, a part of the itagnesium chloride and / or the calcium chloride is immediately available for thawing, while another part of the aforementioned Substances initially still stored in the pores of the mechanically deadening material remains and is only slowly released from these pores. This will make the effect of the spreading material is extended.

Außerdem ist darauf hinzuweisen, daß Magnesiumchlorid sowohl ungiftig wie auch chemisch weitgehend neutral ist.It should also be noted that magnesium chloride is both non-toxic as is also largely chemically neutral.

Eine Weiterentwicklung des Erfindungsgegenstandes besteht darin, daß das poröse Material aus Bims besteht.A further development of the subject matter of the invention is that the porous material consists of pumice.

Es kann allerdings mit Vorteil auch das poröse Material aus Calciumsilikat bestehen.However, the porous material made of calcium silicate can also be used with advantage exist.

Es ist vorteilhaft, wenn dem Streumittel ein Farbstoff beigemischt ist, der bei der Anwendung des Streumittels anhand der Farbintensität die Streukonzentration anzeigen kann.It is advantageous if a dye is added to the scattering material is the concentration of the scattering based on the color intensity when the scattering agent is used can display.

Weiterhin kann es von großem Vorteil sein, dem Streumittel ein Korrosionsschutzmittel beizumischen.It can also be of great advantage to add an anti-corrosion agent to the grit to mix in.

Außer den schon angeführten Vorteilen kommt dem neuen Streumittel der Vorteil zu, daß es gegenüber herkömmlichen Streumitteln in geringerer Konzentration verwendet werden kann, da die Wirkung des Calciumchlorids und/oder des Magnesiumchlorids erheblich besser ist als die von üblicherweise verwendetem Natriumchlorid.In addition to the advantages already mentioned, there is also the new grit the advantage that it is in a lower concentration compared to conventional grit can be used because of the effect of calcium chloride and / or magnesium chloride is significantly better than that of commonly used sodium chloride.

Sehr vorteilhaft ist es, wenn dem Streumittel Kompensatoren wie Kunstdünger und/oder andere Pflanzennährstoffe beigemengt sind, da diese die schädigende Wirkung auf die Vegetation ausgleichen können.It is very advantageous if compensators such as artificial fertilizers are added to the spreading material and / or other plant nutrients are added, as these have the damaging effect can balance on the vegetation.
