Abstract
Description
Die Erfindung betrifft ein Verfahren zur Intensivierung von Waschprozessen mittels eines Kontaktmaterials.The invention relates to a method for intensifying Washing processes using a contact material.
Waschaktive, im Waschwasser lösliche seifenhaltige oder nicht seifenhaltige Reinigungsmittel sind in einer Vielzahl von Verbindungen bekannt. Darunter fallen beispielsweise auch oberflächenaktive, nicht seifenhaltige Reinigungsmittel mit wenigstens einer Carbonate umfassenden Komponente, beispielsweise Carbonsäuren oder deren Salze. Darüber hinaus ist eine Vielzahl anderer organischer oder anorganischer Verbindungen als Reinigungs- oder Waschmittel bekannt, insbesondere Seifen aus Fettsäurekondensationsprodukten. Ein allen waschaktiven, in Waschwasser löslichen Reinigungsmitteln gemeinsamer Nachteil besteht darin, daß sie zur Erzielung einer zufriedenstellenden Reinheit von textiler Wäsche oder Geschirr relativ hoch dosiert werden müssen. Dadurch entsteht eine Waschlauge, deren Reste durch sehr intensive und mehrfach wiederholte Spülvorgänge vom Waschgut abgespült werden müssen, wodurch ein hoher Wasserverbrauch und ein entsprechend hoher Abwasseranfall verursacht werden. Laugenreste erzeugen darüberhinaus den häßlichen Grauschleier in gewaschenen Textilien und setzen sich als Kalk- und Carbonatansätze an Teilen von Waschmaschinen, bevorzugt an Heizstäben an und sind dort Verursacher größerer Schäden. Beim Reinigen bzw. Spülen von Geschirr verursachen schwer abspülbare Laugenreste ebenfalls eine Art von Grauschleier, der insbesondere an Glaswaren als häßlich empfunden wird und eine manuelle Nachreinigung erforderlich macht. Alle diese Nachteile führen nicht nur zu unerwünscht hohen Kosten beim Waschen sowie zur Umweltbelastung des Abwassers, sondern auch zu Mehrarbeit im Haushalt.Wash-active, soap-based water soluble or not Soap detergents are available in a variety of Connections known. This includes, for example surface-active, non-soap-containing cleaning agents at least one component comprising carbonates, for example carboxylic acids or their salts. Furthermore is a variety of other organic or inorganic Compounds known as cleaning or washing agents, especially soaps from fatty acid condensation products. On all active washing detergents that are soluble in washing water common disadvantage is that they are to achieve a satisfactory purity of textile laundry or Dishes must be dosed relatively high. This creates a wash liquor, the remains of which are very intense and multiple repeated rinsing must be rinsed off the laundry, whereby a high water consumption and a correspondingly high Wastewater is caused. Generate lye residues moreover the ugly gray veil in washed Textiles and are used as lime and carbonate mixtures Parts of washing machines, preferably on heating elements and are cause greater damage there. When cleaning or rinsing of lye residues that are difficult to wash off also cause a kind of gray veil, which is perceived as ugly, especially on glassware and requires manual post-cleaning. All of these disadvantages result not only at undesirably high costs for washing and environmental pollution of wastewater, but also for extra work in the household.
In der Praxis hat sich weiterhin herausgestellt, daß die Wirkung der auf dem Markt befindlichen Reinigungsmittel sehr unterschiedlich ist und daß einige sowohl Textilien als auch die Haut angreifen.In practice, it has also been found that the effect of the Market cleaning products are very different and that some both Attack textiles as well as the skin.
Um den Waschprozess zu intensivieren ist es bekannt, dem Waschwasser zusätzliche Mittel beizugeben. So wird in dem Dokument DATABASE WPI Section Ch, Week 8403 Derwent Publications Ltd., London, GB; Class A18, AN 84-014760 XP002018429 & JP-A-58 207 903 (SUMITOMO CHEMICAL KK) vom 3. Dezember 1983 ein Verfahren zur Reinigung von Membranen der Ultrafiltration beschrieben, bei dem Perlen aus unterschiedlichen weichen Materialien, wie beispielsweise Kunststoffe als mechanisch wirkendes Kontaktmittel der Waschflüssigkeit zugesetzt werden, um die Abtrennung der an den Membranen anhaftenden Verunreinigungen zu verbessern.In order to intensify the washing process, it is known to add additional washing water To add funds. The document DATABASE WPI Section Ch, Week 8403 Derwent Publications Ltd., London, GB; Class A18, AN 84-014760 XP002018429 & JP-A-58 207 903 (SUMITOMO CHEMICAL KK) dated December 3, 1983 a process for cleaning membranes of ultrafiltration described in which beads made of different soft materials, such as plastics as a mechanically acting contact means of Wash liquid can be added to the separation of the membranes improve adhering impurities.
Aus der US-A-4 051 046 ist es bekannt, dass sich die positive Wirkung auf den Waschprozess bei Verwendung von organischen oberflächenaktiven Stoffen dadurch erhöhen lässt, wenn diesen Stoffen wasserunlösliche Partikel in einer Menge von 0,05 bis 10 % zugemischt werden, beispielsweise Glasperlen. Die zugesetzten Partikel besitzen eine durchschnittliche Korngröße von 5 bis 30 µm, einen Schmelzpunkt über 150 °C und enthalten keine austauschbaren Calcium- und Magnesiumionen.From US-A-4 051 046 it is known that the positive effect on the Washing process when using organic surfactants thereby increasing if these substances water-insoluble particles in a Amount of 0.05 to 10% can be added, for example glass beads. The added particles have an average grain size of 5 to 30 µm, a melting point above 150 ° C and contain no exchangeable calcium and magnesium ions.
Weiterhin ist es allgemein bekannt, Permamentmagnetkörper im Waschwasser als Kontaktmaterial zu verwenden, um auf diese Weise Einfluss auf die Wasserhärte zu nehmen und Kalkablagerungen in beispielsweise Waschmaschinen zu verhindern.Furthermore, it is generally known to have permanent magnet bodies in the wash water to be used as contact material in order to influence the water hardness to take and limescale deposits in, for example, washing machines to prevent.
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zur schonenden Intensivierung eines Waschprozesses mittels eines dem Waschgut - z. B. Textilien oder Geschirr - beizugebenden Kontaktmaterials anzugeben, welches im Zusammenwirken mit üblichen Reinigungsmitteln deren Reinigungskraft deutlich verstärkt, infolgedessen deren erforderliche Menge wesentlich reduziert, gleichzeitig den Wasserverbrauch und Abwasseranfall signifikant verringert und insgesamt damit zu einer Schonung des Waschgutes, Schutz der Haut, Verringerung der schädlichen Kalk-Carbonat-Niederschläge an Waschmaschinen und zu einer verringerten Umweltbelastung führt.The invention is based on the object of a method for gentle intensification a washing process by means of the laundry - e.g. B. Textiles or tableware - contact material to be provided, which in the Interaction with common cleaning agents, their cleaning power clearly strengthened, as a result of which their required amount was significantly reduced, at the same time significantly reduces water consumption and wastewater and overall, therefore, to protect the laundry, protect the skin, reduce the harmful precipitation of lime-carbonate on washing machines and leads to a reduced environmental impact.
Die Lösung der gestellten Aufgabe wird bei einem Verfahren der eingangs genannten Art mit der Erfindung dadurch erreicht, dass zur Absenkung der Oberflächenspannung des Wassers (Entspannung der Wasseroberfläche mit Veränderung der Adhäsions- und Kohäsionskräfte) und zur Optimierung der Carbonat-Härte, Gesamt-Härte und des pH-Wertes des Wassers als Kontaktmaterial wenigstens ein oberflächenaktiv wirkender Polykarbonatkörper in Form von Thermoplastmaterial verwendet wird, der beliebige Form aufweist und beispielsweise als Zylinder, Scheibe, Würfel, Prisma, Quader, Polyeder, Kugel, Kugelabschnitt, Ellipsoid oder Hohlkörper ausgebildet ist und in einer flüssigkeitsdurchlässigen Verpackung verwendet wird.The solution to the problem is in a method of the aforementioned Art achieved with the invention in that to lower the surface tension of the water (relaxation of the water surface with change the adhesive and cohesive forces) and to optimize the carbonate hardness, Total hardness and the pH value of the water as contact material at least one surface-active polycarbonate body in the form of Thermoplastic material is used, which has any shape and for example as cylinder, disc, cube, prism, cuboid, polyhedron, sphere, Spherical section, ellipsoid or hollow body is formed and in a liquid-permeable Packaging is used.
Mit großem Vorteil wird durch die Verwendung eines Polycarbonatkörpers als Kontaktmaterial in überraschender Weise eine Vielzahl von Vorteilen erreicht. Es sind dies:
- Einsparungen bis zu 90 % der bisher für ein Waschgut erforderlichen Reinigungsmittelmenge. Bei geringer Wasserhärte werden für die 30°-Wäsche weniger als 10 % der bisherigen Waschmittelmenge benötigt,
- deutliche Reduzierung der Umweltbelastung infolge Verringerung der chemischen Belastung des Abwassers,
- Optimierung der Carbonat-Härte, Gesamt-Härte und des pH-Wertes vom Waschwasser, sowie hierdurch entsprechend sauerstoffreicheres Wasser,
- Entspannung der Wasseroberfläche mit Veränderung der Adhäsions- und Kohäsionskräfte, als Ergebnis vorteilhafte Weichheit der Wäsche, ggf. ohne oder mit verringertem Weichspüler,
- geringere Waschmittelkonzentration in der Waschlauge, Grauschleier werden reduziert, infolgedessen intensivere Farben und leuchtenderes Weiß der Wäsche, strahlender Glanz beim gespülten Geschirr, verringerte Spülwasser- und Abwassermenge,
- geringeres Flusen von Wolltextilien; im Waschmaschinen-Flusensieb lagern sich weniger Flusen an.
- Kalkansätze in der Waschmaschine werden verringert und geringere Zugaben von Entkalkungsmitteln benötigt.
- Savings of up to 90% of the amount of detergent previously required for laundry. If the water hardness is low, less than 10% of the previous amount of detergent is required for the 30 ° wash,
- significant reduction in environmental pollution due to a reduction in the chemical pollution of the wastewater,
- Optimization of the carbonate hardness, total hardness and the pH value of the wash water, as well as water that is correspondingly richer in oxygen,
- Relaxation of the water surface with changes in the adhesion and cohesion forces, as a result advantageous softness of the laundry, possibly without or with reduced fabric softener,
- lower detergent concentration in the wash liquor, gray veils are reduced, as a result more intensive colors and lighter whiteness of the laundry, radiant shine in the washed dishes, reduced amount of washing water and waste water,
- less fluff of wool textiles; less lint accumulates in the washing machine lint filter.
- Lime deposits in the washing machine are reduced and less additions of descaling agents are required.
Bei einer Geschirreinigung von Hand genügt die Zugabe von einigen Tropfen flüssigen Reinigungs- bzw. Spülmittels ins Wasser, wobei weniger Reste dieser Mittel auf dem Geschirr zurückbleiben, weshalb eine manuelle Nacharbeit entfallen kann; zur Reinigung des Waschbeckens sind keine Scheuermittel erforderlich, die Hände bzw. die Haut bleibt geschmeidig und quillt bei längerem Waschen und Spülen nicht auf.When washing dishes by hand, the addition of is sufficient a few drops of liquid detergent or detergent Water, leaving less remnants of these agents on the dishes remain behind, which is why manual rework is not necessary can; to clean the sink are no abrasives required, the hands or skin remains supple and does not swell after prolonged washing and rinsing.
Bei Verwendung einer Spülmaschine ergibt sich bei der Geschirr-Reinigung eine bis zu 90%ige Einsparung an Spülmittel. Gemeinsame Vorteile beim Geschirrspülen von Hand oder mit Maschine sind auffälliger Glanz auf Bestecken und Geschirr, mithin eine deutlich verbesserte Reinigungswirkung infolge Entspannung der Wasseroberfläche. Kostenreduzierung sowie Umweltfreundlichkeit des Abwassers sind weitere deutliche Vorteile gegenüber den bisherigen Wasch- und Spülverfahren.When using a dishwasher, the results in Dish cleaning up to 90% savings Detergent. Common advantages of hand washing or with machine are striking shine on cutlery and Dishes, therefore a significantly improved cleaning effect due to relaxation of the water surface. Cost reduction and environmental friendliness of the wastewater are further clear advantages over previous washing and Flushing process.
Eine Ausgestaltung des Verfahrens sieht vor, daß der Waschpder Spülprozeß mit Flüssigkeit durchgeführt wird, die außer Wasser nur noch sehr geringe Anteile Reinigungs- bzw. Spülmittel und ggf. weniger Enthärtungs- und/oder Entspannungsmittel enthält, und der als Kontaktkörper Polycarbonate in fester Form als Thermoplastmaterial zugegeben werden.An embodiment of the method provides that the washing powder Flushing process is carried out with liquid that except Water only very small proportions of cleaning or Detergent and possibly less softening and / or Contains relaxants, and that as a contact body Polycarbonate in solid form added as a thermoplastic material become.
Mit Vorteil bleiben die Polycarbonatkörper auch bei wiederholtem Gebrauch in ihrer Wirkung unverändert, d.h. sie zeigen keine Abnutzungserscheinungen.The polycarbonate bodies also remain with advantage repeated use unchanged in their effect, i.e. she show no signs of wear.
Als Kontaktkörper können beliebige Formen, beispielsweise Zylinder, Scheiben, Würfel, Prismen, Quader, Polyeder, Kugeln, Kugelabschnitte, Ellipsoide, Hohlkörper o.ä. verwendet werden, vorzugsweise scheibenförmige Zylinder mit einem Durchmesser von ca. 5 cm und einer Dicke von 1 cm.Any shapes, for example, can be used as contact bodies Cylinders, disks, cubes, prisms, cuboids, polyhedra, spheres, Ball sections, ellipsoids, hollow bodies or similar be used, preferably disc-shaped cylinders with a diameter of approx. 5 cm and a thickness of 1 cm.
Weil die Wirkung des Kontaktmaterials oberflächenaktiver Natur ist, besteht ein Zusammenhang zwischen der insgesamt zur Verfügung stehenden aktiven Oberfläche der Kontaktkörper und deren Wirkung. Infolgedessen sieht eine vorzugsweise Ausgestaltung der Erfindung vor, daß als Kontaktkörper ein Haufwerk von Kleinkörpern, Kugeln, Perlen, Bruchstücken etc. in einer flüssigkeitsdurchlässigen Verpackung verwendet werden. Durch diese Maßnahme kann die aktive Oberfläche in an sich bekannter Weise gegenüber einem oder wenigen größeren Körpern gleicher Masse nahezu beliebig vervielfältigt werden. Es kann auch vorgesehen sein, daß als Kontaktkörper Fasern oder Folien aus Polycarbonatmaterial verwendet werden.Because the effect of the contact material is surface-active in nature there is a connection between the total of Available active surface of the contact body and their effect. As a result, one sees preferably Embodiment of the invention that as a contact body Pile of small objects, balls, pearls, fragments etc. used in a liquid-permeable packaging become. By this measure, the active surface in can known manner towards one or a few larger ones Bodies of the same mass can be reproduced almost arbitrarily. It can also be provided that fibers as the contact body or films made of polycarbonate material can be used.
Mit den vorgenannten Maßnahmen ist es zweckmäßig, daß die zur Erzielung einer vorgesehenen Kontaktwirkung erforderliche Größe der aktiven Oberfläche des Polycarbonatmaterials nach Maßgabe des Volumens der Reinigungsflüssigkeit sowie von Menge und/oder Gewicht des Waschgutes, dessen Verschmutzungsgrad und/oder der Reinigungsmittelkonzentration in der Waschlauge bemessen wird.With the above measures, it is appropriate that the Achievement of an intended contact effect required Size of the active surface of the polycarbonate material Determining the volume of the cleaning liquid and the amount and / or weight of the laundry, its degree of soiling and / or the detergent concentration in the wash liquor is measured.
Weiterhin kann die aktive Oberfläche und/oder Menge des Polycarbonatmaterials nach Maßgabe der Carbonat-Härte, Gesamt-Härte und pH-Wert des Wassers bemessen werden.Furthermore, the active surface and / or amount of Polycarbonate material according to the carbonate hardness, Total hardness and pH of the water can be measured.
