Abstract

The drain cleaner acts to dissolve fats and break down hair and consists of an alkaline liquid of the following composition: 5-20% by weight caustic alkali (100% strength), 20-60% by weight alkali metal hypochlorite solution (10-15% active chlorine), 0-10% by weight alkali metal nitrate and 20-70% by weight water in separate combination with light metal turnings or granules which evolve heat to reach 80-100 DEG C on use, preferably aluminium granules (5-15 g/250 ml of alkaline liquid).

Description

Die Erfindung betrifft Abflußreiniger mit fettlösender und haarzerkleinernder Wirkung, bestehend aus einer alkalischen Flüssigkeit in Kombination mit Leichtretallspänen oder -pranulaten, die bei der Anwendung eine hohe Wärmeentwicklung aufweisen.The invention relates to drain cleaners with a fat-dissolving and hair-crushing effect, consisting of an alkaline liquid in combination with light-alloy chips or granules, which have a high heat development when used.

Übliche Abfluß- bzw. Rohrreiniger stellen feste Gemische auf Basis von Matriur.hydroxic, Aluriniurspanen und Natriumnitrat, gegebenenfalls rit speziellen haarzerkleinernden Zusätzen, dar. Diese Mischungen entwickeln bei Zugabe von Wasser Wärre und sind dadurch bei der Entfernung von festen und halbfesten Fettverschrutzungen besonders wirksam. Weiterhin sind flüssige Abflußreiniger auf der Basis vcn Ätzalkalien oder Alkalihypochlorit in Gebrauch. Diese Reiniger wirken durch Verseifung von Fettstoffen und besitzen z. T. auch haarlösende Wirkung, es fehlt ihnen aber die zur wirksamen Entfernung von Fettverstopfunren erforderliche Wärrereaktion. Schließlich kennt man auch Abflußreiniger, die aus einer flüssigen Gemisch aus Alkalilauge und Natriumnitrat in Kombination mit festem Aluriniurgranulat bestehen, die in getrennter Form in den Handel kommen und erst bei der Anwendung zusammen in den verstopften Abfluß gegeben werden. Durch die Reaktjon des Alkalis mit dem Aluminium wird Wärre entwickelt, wodurch jedoch raxiral 60° C ir Abfluß erreicht werden, was zur wirkungsvollen Auflösung von Fettverstopfungen nicht ausreicht. Außercer besitzt diese Kombination ungenügende haarzerkleinernde Wirkung.Common drain and pipe cleaners are solid mixtures based on Matriur.hydroxic, Aluriniurspanen and sodium nitrate, possibly with special hair-reducing additives. These mixtures develop heat when water is added and are therefore particularly effective in removing solid and semi-solid grease contaminations. Liquid drain cleaners based on caustic alkalis or alkali hypochlorite are also used. These cleaners work by saponifying fatty substances and have z. Some also have a hair-releasing effect, but they lack the heat reaction required to effectively remove fat blockages. Finally, there are also known drain cleaners, which consist of a liquid mixture of alkali lye and sodium nitrate in combination with solid Aluriniur granulate, which are sold separately and are only put together in the blocked drain when used. Through the reaction of the alkali with the aluminum, heat is developed, but a maximum of 60 ° C is achieved in the drain, which is not sufficient for the effective dissolution of fat blockages. Addition this combination has insufficient hair-crushing effects.

Gegenstand der Erfindung sind Abflußreiniger mit fettlösender und haarzerkleinernder Wirkung auf der Basis einer alkalischen Flüssigkeit und einem davon getrennten Leichtmetall, vorzugseeise Alurinium, in Span- oder Granulatform, dadurch gekennzeichnet, daß die alkalische Flüssigkeit folgende Zusammensetzung aufweist:

The invention relates to drain cleaners with grease-dissolving and hair-crushing action based on an alkaline liquid and a separate light metal, preferably aluminum, in chip or granular form, characterized in that the alkaline liquid has the following composition:
Figure imgb0001

Als Ätzalkalien werden vorzugsweise Natrium- oder Kaliur:- hydroxid eingesetzt.Sodium hydroxide or potassium hydroxide are preferably used as caustic alkalis.

Alkalihypochloritlösungen sind als Chlorbleichlauge mit einem Gehalt von etwa 13 % Aktivchlor handelsüblich. Als Alkalinitrat wird Natriun- oder Kaliumnitrat bevorzugt.Alkali hypochlorite solutions are commercially available as chlorine bleach with a content of approximately 13% active chlorine. Sodium or potassium nitrate is preferred as the alkali nitrate.

Zur Beseitigung von Abflußverstopfungen wird die alka- lische Flüssigkeit zusagen mit einem Leichtmetall in Span- oder Granulatform, vorzugsweise Aluniniumgrieß, in den Abfluß gegeben. Durch die entstehende Reaktionswärme werden überraschenderweise Temperaturen bis zu 85°C erreicht; bei Anwesenheit von Alkalinitrat bis 100° C, was in Verbindung mit der haarzerkleindernden Wirkung zu einer schnellen und sicheren Auflösung von Fett und Haare enthaltenden Schirutzpfropfen führt.To remove drainage blockages, the alkaline liquid is added to the drain with a light metal in chip or granulate form, preferably aluminum grit. The resulting heat of reaction surprisingly reaches temperatures of up to 85 ° C; in the presence of alkali nitrate up to 100 ° C, which in connection with the hair-shrinking effect leads to a quick and safe dissolution of graft containing hair and graft.

Auf etwa 25c rl der alkalischen Flüssigkeit werden 5 - 15 g Aluriniumgrieß angewendet. Diese Menge reicht auch in der Regel zur Reinigung eines verstonften Abflusses aus.5 - 15 g of semolina are applied to about 25 ml of the alkaline liquid. This amount is also usually sufficient to clean a polluted drain.
