Description

Verfahren zur Beseitigung von Einschlüssen auf Fliesenoberflächen und Mittel hierzu Process for removing inclusions on tile surfaces and means therefor
Die Erfindung betrifft ein Verfahren zur Beseitigung von Einschlüssen auf Fliesenoberflächen mit den Merkmalen des Oberbegriffs des Anspruches 1 und ein Mittel hierzu mit den Merkmalen des Oberbegriffs des Anspruches 3.The invention relates to a method for removing inclusions on tile surfaces with the features of the preamble of claim 1 and a means for this with the features of the preamble of claim 3.
Auf verschiedenen Baustellen, wie beispielsweise Großküchen, Großraumduschen, Schwimmbädern oder anderen Dauernaßbereichen wird heutzutage ein Fliesenbelag verwendet, der mit einem sehr hoch chemikalienbeständigen Material verfugt wird. Üblicherweise wird hierfür ein Epoxidharz oder Silikat-Glasharz verwendet. Dieses ist beispielsweise beständig gegen tierische und pflanzliche Fette, chlorhaltiges Wasser und aggressive Reinigungsmittel. Die gute Beständigkeit der Fugen wird nach einer Aushärtungszeit von etwa sieben Tagen erreicht.At various construction sites, such as commercial kitchens, open-plan showers, swimming pools or other permanent wet areas, a tile covering is used today that is grouted with a very highly chemical-resistant material. An epoxy resin or silicate glass resin is usually used for this. This is, for example, resistant to animal and vegetable fats, chlorinated water and aggressive cleaning agents. The good resistance of the joints is achieved after a curing time of around seven days.
Beim Verfugen kommt grundsätzlich auch die Fliesenoberfläche in Kontakt mit dem Epoxidharz. Da in der Regel keine vollständige Reinigung der Fliesenoberfläche nach dem Verfugen durchgeführt wird, bleibt ein gewisser Restschleier aus Epoxidharz auf der Fliesenoberfläche, der bis zum Ende der Aushärtungszeit frisch bleibt. Dies alleine führt nicht notwendigerweise zu einer Beeinträchtung der Fliesenoberfläche, wenn der geflieste Bereich bis zur vollständigen Aushärtung freigehalten wird, sondern bietet sogar einen zusätzlichen Schutz.When grouting, the tile surface always comes into contact with the epoxy resin. Since the tile surface is usually not completely cleaned after grouting, a certain amount of residual epoxy resin remains on the tile surface, which remains fresh until the end of the curing time. This alone leads not necessarily affect the tile surface if the tiled area is kept free until it has completely hardened, but even offers additional protection.
Da aber heutzutage auf dem Bau ein sehr enger Terminplan vorgegeben ist, wird in der Regel der Ablauf der Aushärtungszeit nicht abgewartet, sondern währenddessen in den gefliesten Bereichen mit anderen Arbeiten begonnen. Wenn Arbeiter während der Aushärtungszeit über den nicht vollständig ausgehärteten Fliesenbelag gehen und/oder auf diesem arbeiten, entsteht Schmutz, Dreck und Staub, der auf der Fliesenoberfläche landet und sich mit dem noch nicht ausgehärteten Epoxidharz verbindet. Nach der Aushärtung sind dann sichtbare Dreckeinschlüsse auf der Fliesenoberfläche vorhanden, die auch bei der abschließenden Baustellenreinigung mit bekannten Reinigungsmitteln nicht entfernbar sind. Das Erscheinungsbild des Fliesenbelags wird dadurch stark beeinträchtigt. Häufig nimmt der Bauherr den gefliesten Bereich nicht ab, fordert eine Mängelbeseitigung durch Neuverfliesen und den Ersatz des entstandenen Schadens.However, since a very tight schedule is set for construction these days, the curing time is generally not waited for, but other work is started in the tiled areas. If workers walk over and / or work on the incompletely hardened tile covering during the hardening period, dirt, dirt and dust is created which lands on the tile surface and bonds with the not yet hardened epoxy resin. After curing, there are visible dirt inclusions on the tile surface, which cannot be removed even with the final cleaning of the construction site using known cleaning agents. The appearance of the tile covering is greatly affected. Often the builder does not accept the tiled area, demands that the faults be remedied by re-tiling and that the resulting damage be replaced.
Der vorliegenden Erfindung liegt die daher Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu verbessern und ein hierfür geeignetes Mittel zur Verfügung zu stellen. Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruches 1 und ein Mittel mit den Merkmalen des Anspruches 3 gelöst. Weitere vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The present invention is therefore based on the object of improving a method of the type mentioned at the outset and of making available a suitable means. This object is achieved by a method with the features of claim 1 and a means with the features of claim 3. Further advantageous embodiments are the subject of the dependent claims.
Dadurch, daß ein Reinigungsmittel aufgebracht wird, welches die Reste des ausgehärteten Verfugungsmaterials einschließlich der Einschlüsse chemisch ablöst, kann ein Neuverfliesen und Neuverfugen entfallen. Dies erlaubt eine kostengünstigere und schnellere Mängelbeseitigung. Das Reinigungsmittel kann für Kunstharze, wie beispielsweise Epoxidharz, oder für Silikat-Glasharz als Verfugungsmaterial eingesetzt werden. Das eingesetzte Reinigungsmittel ist vorzugsweise weitgehend biologisch abbaubar, was die Kosten für die nachfolgende Entsorgung stark verringert. Das Reinigungsmittel enthält vorzugsweise organische Lösungsmittel mit verschiedenen Zusätzen zur Verstärkung der Wirkung. Ein hoher Anteil an organischen Substanzen fördert die biologischer Abbau- barkeit. Um das Reinigungsmittel einerseits außer an horizontalen Flächen auch an vertikalen Fliesenbereichen, beispielsweise Wänden, einsetzen zu können und andererseits eine gewisse Einwirkzeit zur Verfügung zu haben, enthält das Reinigungsmittel vorzugsweise ein sogenanntes Stellmittel, welches eine pastöse Konsistenz des Reinigungsmittels bewirkt.The fact that a cleaning agent is applied which chemically detaches the remains of the hardened jointing material, including the inclusions, means that tiling and re-grouting can be omitted. This allows a more cost-effective and faster remedy of defects. The cleaning agent can be used as a jointing material for synthetic resins, such as epoxy resin, or for silicate glass resin. The cleaning agent used is preferably largely biodegradable, which greatly reduces the costs for subsequent disposal. The cleaning agent preferably contains organic solvents with various additives to reinforce the Effect. A high proportion of organic substances promotes biodegradability. In order to be able to use the cleaning agent on the one hand in addition to horizontal surfaces also on vertical tile areas, for example walls, and on the other hand to have a certain exposure time available, the cleaning agent preferably contains a so-called adjusting agent which brings about a pasty consistency of the cleaning agent.
Im folgenden ist die Erfindung anhand eines Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt einen teilweise mit einem verschmutzten Epoxidharzschleier versehenen und teilweise gereinigten Fliesenbereich.The invention is explained in more detail below using an exemplary embodiment. The only figure shows a tile area partially provided with a dirty epoxy resin veil and partially cleaned.
Der Fliesenbereich 1 besteht aus mehreren, geringfügig voneinander beabstandeten Fliesen 2 mit Epoxidharzfugen 3 dazwischen und ist zunächst mit einem verschmutzten Epoxidharzschleier 4 verunreinigt. Das beispielhafte Reinigungsmittel zum Entfernen von Epoxidharzresten besteht zu 50 Vol% bis 90 Vol%, vorzugsweise etwa 75 Vol% bis 80 Vol%, aus Benzylalkohol C6H5-CH2θH, der vor der Zubereitung des Reinigungsmittels 99 % technisch rein ist. Der Benzylalkohol zeigt bereits alleine eine gewisse Reinigungswirkung bei der gewünschten Anwendung, und zwar konnten in Versuchen erstaunlicherweise bereits durchschnittlich 60 % des Epoxidharzschleiers entfernt werden. Zur Verstärkung der Reinigungswirkung und zur Beschleunigung der Reinigungszeit, insbesondere zur Verkürzung der Einwirkzeit und zur Schonung benachbarter Fugen, wird dem Reinigungsmittel mit einem Anteil von etwa 10 Vol% bis 12 Vol% Butyldigly- colacetat C4H9-0-C2H4-0-C2H4-0-CO-CH3 beigegeben, welches 100 % technisch rein ist. Mit dieser Mischung konnten in Versuchen überraschenderweise bereits 97 % des Epoxidharzharzschleiers entfernt werden. Als Stellmittel enthält das Reinigungsmittel etwa 1 Vol% bis zu 8 Vol% pyrogene Kieselsäure H4Si04, welche 100 % technisch rein ist.The tile area 1 consists of several, slightly spaced apart tiles 2 with epoxy resin joints 3 in between and is initially contaminated with a dirty epoxy resin veil 4. The exemplary cleaning agent for removing epoxy resin residues consists of 50% by volume to 90% by volume, preferably approximately 75% by volume to 80% by volume, of benzyl alcohol C 6 H 5 -CH 2 θH, which is 99% technically pure before the preparation of the cleaning agent. The benzyl alcohol alone shows a certain cleaning effect in the desired application, and surprisingly, tests have already been able to remove an average of 60% of the epoxy resin film. To increase the cleaning effect and to accelerate the cleaning time, in particular to shorten the exposure time and to protect neighboring joints, the detergent is used with a proportion of about 10 vol.% To 12 vol.% Butyl diglycol acetate C 4 H 9 -0-C 2 H 4 -0-C 2 H 4 -0-CO-CH 3 added, which is 100% technically pure. Surprisingly, this mixture was able to remove 97% of the epoxy resin veil in experiments. The cleaning agent contains about 1% by volume up to 8% by volume pyrogenic silica H 4 Si0 4 , which is 100% technically pure.
Zur weiteren Verstärkung der Wirkung und Verkürzung der Reinigungszeit kann das beispielhafte Reinigungsmittel kleine Mengen weiterer Wirkstoffe, vorzugsweise organische Substanzen, aufweisen, beispielsweise Äthylalkohol C2H5OH, Essigsäure CH3-COOH, Ameisensäure H-COOH, Aceton CH3-CO-CH3 oder aridere organische Säuren und Ten- side, aber auch beispielsweise Salzsäure HCl oder verdünnte Natronlauge NaOH, jeweils vorzugsweise in einer Menge von etwa 1 Vol%, 2 Vol% oder 3 Vol% und in einer technischen Reinheit von 60 % bis 100 %. Ein Zusatz von Wasser ist möglich, beispielsweise bis zu 20 Vol%. Die genaue Zusammensetzung des Reinigungsmittels ist auf das verwendete Fugenmaterial abstimmbar. Entsprechend verringern oder erhöhen sich die Anteile der für das beispielhafte Reinigungsmittel genannten Bestandteile. In Versuchen konnte der Epoxidharzschleier zu nahezu 100 % entfernt werden.To further increase the effectiveness and shorten the cleaning time, the exemplary cleaning agent can contain small amounts of other active ingredients, preferably organic Substances, for example ethyl alcohol C 2 H 5 OH, acetic acid CH 3 -COOH, formic acid H-COOH, acetone CH 3 -CO-CH 3 or other organic acids and surfactants, but also for example hydrochloric acid HCl or dilute sodium hydroxide solution NaOH, each preferably in an amount of about 1 vol%, 2 vol% or 3 vol% and in an industrial purity of 60% to 100%. It is possible to add water, for example up to 20% by volume. The exact composition of the cleaning agent can be matched to the joint material used. The proportions of the constituents mentioned for the exemplary cleaning agent decrease or increase accordingly. In experiments, almost 100% of the epoxy veil could be removed.
Das beispielhafte Reinigungsmittel ist pastös bis flüssig (je nach Stellmittelanteil). Die Farbe ist bei geringem Stellmittelanteil (etwa 1 Vol%) klar und bei höherem Stellmittelanteil weiß bis opak. Es ergibt sich ein mild aromatischer Geruch (leicht nach Bittermandel). Dis Viskosität beträgt bei 20° C etwa 300 bis 600 mPS, der pH- Wert etwa 6,0, das Festkörpergewicht etwa 9,8 % und der Lösemittelgehalt etwa 90 %. Das Reinigungsmittel ist zu 99,8 % voll biologisch abbaubar (EN Norm 2988). Es bildet in Wasser eine Emulsion.The exemplary cleaning agent is pasty to liquid (depending on the proportion of the adjusting agent). The color is clear with a small amount of adjusting agent (approx. 1% by volume) and white to opaque with a higher amount of adjusting agent. The result is a mild aromatic smell (slightly bitter almond). The viscosity at 20 ° C is about 300 to 600 mPS, the pH about 6.0, the solids weight about 9.8% and the solvent content about 90%. The cleaning agent is 99.8% fully biodegradable (EN standard 2988). It forms an emulsion in water.
Das beispielhafte Reinigungsmittel wird gleichmäßig auf die verunreinigte Fliesenoberfläche der Fliesen 2 aufgebracht. Während einer relativ kurzen Einwirkzeit von ca. 20 Minuten werden die Verfugungsmaterialstände, vorliegend die Epoxidharzrückstände, samt den Schmutzeinflüssen schonend abgelöst. Je nach Art des Verfugungsmaterials und Stärke des Schleiers kann es sein, daß das Reinigungsmittel mehrmals hintereinander einzusetzen ist. Insgesamt ist eine vollständige Entfernung des verdreckten Epoxidharzschleiers 4 gewährleistet, ohne daß dabei die Fliesenoberfläche angegriffen oder die Epoxidharzfuge 3 beeinträchtigt wird. Nach Ablauf der Einwirkzeit kann das Reinigungsmittel mit samt den aufgelösten Rückständen entfernt und aufgrund der biologischen Abbaubarkeit umweltgerecht entsorgt werden. The exemplary cleaning agent is applied evenly to the contaminated tile surface of the tiles 2. During a relatively short exposure time of approx. 20 minutes, the grouting material levels, in the present case the epoxy resin residues, together with the influences of dirt, are carefully removed. Depending on the type of grouting material and the thickness of the veil, it may be necessary to use the cleaning agent several times in succession. Overall, a complete removal of the dirty epoxy resin veil 4 is ensured without the tile surface being attacked or the epoxy resin joint 3 being impaired. After the exposure time has elapsed, the cleaning agent and the dissolved residues can be removed and disposed of in an environmentally friendly manner due to its biodegradability.
