Verfahren -und Mittel zur Nachpflege hölzérnez*Masten, Pfosten undProcedure -and means of aftercare woodenérnez * masts, posts and
dergleichen Holzmasten und ähnliche hölzerne Konstruktionselemente, die zur Einlassung- in den Erdboden bestimmt sind, werden zum Schutz gegen holzzerstörende Pilze und Tiereumit fungiziden und/oder insektiziden Mitteln behandelt.like that Wooden poles and similar wooden construction elements, which are intended to be embedded in the ground are used to protect against wood-destroying Fungi and animals treated with fungicidal and / or insecticidal agents.
Bekannte Mittel dieser Art sind z.B. Kupfer-, Bor-, -Chrom-, Arsen- und andere Schwermetallverbindungen, unspezifisch wirkende organische Verbinzungen wie Teeröle und eine Vielzahl von mehr-oder minder spezifisch wirkenden Stoffen. Well-known agents of this type are e.g. copper, boron, chromium, arsenic and other heavy metal compounds, unspecific organic compounds such as tar oils and a large number of more or less specific substances.
Die ubliche Behandlung der Holzbauteile ist die Imprägnierung, üblicherweise unter abwechselnder Verminderung und Erhöhung des Außendrucks (sog. The usual treatment of wooden components is impregnation, usually with alternating decrease and increase of the external pressure (so-called.
Druckimprägnierung). Der Nachteil der Druckimprägnierung beruht darauf, daß viele Holzarten nur im sog. Splintbereich radial flüssigkeitsdurchlässig sind. Die Imprägnierung erreicht also nicht das Kernholz, das von ,-ganz bestimmten Pilzen - sog. Kernholzspezialisten - bevorzugt angegriffen wird und dann das Schadbild der Kern- oder Innenfäule zeigt. Es ist zwar schon vorgeschlagen worden, eine Kernholzimprägnierung nach künstlicher Perforation des Stammes vorzunehmen oder den frischgefällten Stamm von der Schnittstelle her zu imprägnieren. Diese Verfahren haben sich aber als nicht praktikabel erwiesen. Pressure impregnation). The disadvantage of pressure impregnation is based on that many types of wood are only radially permeable to liquid in the so-called sapwood area. So the impregnation does not reach the heartwood, that of, -specific mushrooms - so-called heartwood specialists - is preferably attacked and then the damage the core or inner rot shows. Heartwood impregnation has already been proposed after artificial perforation of the trunk or the freshly felled trunk to be impregnated from the interface. These procedures have proven to be not proven practicable.
Es ist daher üblich, den Kernholzbereich durch einzelne, d.h. relativ wenige und entsprechende weite Bohrungen zu erschließen, die Bohrungen mit einem Imprägniermittelvorrat zu versehen und dann mit einem Pfropf zu verschließen. Dieses Verfahren wird vor allem zur sog. Nachpflege angewendet; der Stamm wird also nach einer Anzahl von Standjahren wieder ausgegraben bzw. der vergrabene Fuß freigelegt, angebohrt und entsprechend versorgt. It is therefore customary to divide the heartwood area by individual, i.e. relatively To develop a few and corresponding wide holes, the holes with a To provide impregnating agent supply and then to close with a plug. This The procedure is mainly used for so-called follow-up care; so the trunk is after dug up again for a number of years or the buried foot exposed, drilled and supplied accordingly.
Ublich sind für die Nachpflege Mittel, die leicht diffundierende, biozide Stoffe freisetzen; ein solches Mittel besteht z.B. aus einer wäßrigen Lösung von Na- N-Methyldithiocarbamat. Hieraus entwickelt sich durch Zersetzung das biozid wirksame Methylisothiocyanat. For aftercare, products that are easily diffusing, release biocidal substances; such an agent consists, for example, of an aqueous solution of Na-N-methyldithiocarbamate. The biocide develops from this through decomposition effective methyl isothiocyanate.
Da diese Zersetzung bei Kontakt mit Wasser beginnt, zersetzt sich Na-N--Methyldithiocarbamat bereits in seiner wäßrigen Lösung. Das Mittel soll im Stamm aber erst wirksam werden, wenn Feuchtigkeit auftritt, die die Voraussetzung für Innenfäule ist; in trockenem Holz soll das Mittel als Depot vorhanden bleiben. Since this decomposition begins on contact with water, it decomposes Na-N - methyldithiocarbamate already in its aqueous solution. The means should be in Strain only become effective when moisture occurs, which the pre-condition for indoor rot is; in dry wood, the agent should remain available as a depot.
Es wurde nun ein Mittel gefunden, das biozide diffundierbare Stoffe erst bei Anwesenheit von Feuchtigkeit freisetzt. Grundlage des Mittels ist das Ublicherweise mit dem Trivialnamen (common name) Dazomet bezeichnete Tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazin-2-thion. Dieser Stoff wird an sich zur Bodenentseuchung und zur fungiziden Ausrüstung z.B. von Papierleimen u.ã. verwendet und setzt mit Wasser Methylisothiocyanat frei. A means has now been found that contains biocidal diffusible substances only released in the presence of moisture. This is usually the basis of the remedy Tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazin-2-thione referred to by the common name (common name) Dazomet. This substance is used per se for soil disinfection and for fungicidal treatment e.g. of paper glue etc. uses and releases methyl isothiocyanate with water.
Erfindungsgemäß wird das Mittel im wesentlichen wasserfrei angewendet und enthält zu diesem Zweck außer Dazomet ein wasserfreies Lösungs- oder Dispersionsmittel und vorzugsweise zusätzlich einen Stabilisator, der den vorzeitigen Zerfall des Dazomet in die wirksame Verbindung, eben das Methylisothiocyanat verhindert. According to the invention, the agent is used essentially anhydrous and for this purpose contains, in addition to Dazomet, an anhydrous solvent or dispersant and preferably additionally a stabilizer, which prevents the premature breakdown of the Dazomet in the active compound that prevents methyl isothiocyanate.
Als wasserfreies Lösungs- bzw. Dispersionsmittel wird z.B.-ein Polyglykol, vorzugsweise Polypropylenglykol verwendet. Polyglykole mit einer geeigneten Viskosität haben nach Angaben der Hersteller mittlere Molekulargewichte Mv von etwa 600 bis 1000. A polyglycol, for example, is used as an anhydrous solvent or dispersion medium preferably used polypropylene glycol. Polyglycols with a suitable viscosity have average molecular weights Mv of about 600 to, according to the manufacturer 1000.
Eine ebenfalls geeignete Gruppe von Dispersionsmitteln ist die Gruppe der kationaktiven Netz- und Dispergiermittel vom Typ der Benzylammoniumsalze. Another suitable group of dispersants is the group of the cationic wetting and dispersing agents of the benzylammonium salt type.
Diese Stoffe sind selbst biozid wirksam und bilden in wasserfreier Form oftmals mehr oder minder viskose Flüssigkeiten. These substances are themselves biocidal and form in anhydrous Often form more or less viscous liquids.
Die Menge an Dazomet, die man dispergiert, liegt i.a. oberhalb von 10 Gew.%, z.B. zwischen 25 und 50 Gew.%, bezogen auf das Gesamtgewicht des Mittels. The amount of Dazomet that is dispersed is i.a. above of 10% by weight, e.g. between 25 and 50% by weight, based on the total weight of the agent.
Als Stabilisator kann man eine Schwermetallverbindung verwenden, z.B. A heavy metal compound can be used as a stabilizer, e.g.
eine Zinkverbindung, nobei in dem erfindungsgemäßen Mittel im allgemeinen eine wirksame Menge unter 5 Gew.% vorhanden sein sollte. Unter "Verbindung".wird z.B. ein Salz, ein Oxid oder Hydroxid verstanden. Zinkoxid ist eine gut geeignete Zinkverbindung. a zinc compound, nobei in the agent according to the invention in general an effective amount below 5% by weight should be present. Under "Connection". Is for example a salt, an oxide or a hydroxide. Zinc oxide is a good one Zinc compound.
Die Wirkung der Schwermetallverbindung wird unterstützt durch Zu-satz eines schwerflüchtigen Amins, z.B. eines Alkanolamins; ein Beispiel für solche Amine ist Monoethanolamin. Der Mengenanteil in dem Mittel beträgt i.a. 1 bis 5 Gew.%. The effect of the heavy metal compound is supported by additional a non-volatile amine such as an alkanolamine; an example of such amines is monoethanolamine. The proportion in the average is generally 1 to 5% by weight.
Verbesserte Netzfähigkeit des erfindungsgemäßen Mittels kann man, falls erforderlich, noch durch Zusatz eines üblichen ionogenen oder nichtiono- genen Netzmittels, z.B. eines Alkalisalzes eines Alkylarylsulfonats erzielen. Sein Anteil an dem erfindungsgemäßen Mittel liegt i.a. unter -10 Gew.%. Improved wetting ability of the agent according to the invention can be if necessary, by adding a customary ionic or non-ionic genes Wetting agents, e.g., an alkali salt of an alkylarylsulfonate. His share the agent according to the invention is i.a. less than -10% by weight.
Mittel, wie sie die Erfindung vorsieht, haben im allgemeinen pastenförmige Konsistenz und werden durch schon verfUgbare Geräte appliziert. Agents as provided by the invention are generally pasty Consistency and are applied by devices that are already available.
Ein solches Gerät ist z.B. ein Imptstichgerät oder eine Einschraubpresse. Such a device is, for example, an impregnation device or a screw-in press.
Die Verfüllung eines vorher erzeugten Bohrlochs kann auch mit anderen -Vorrichtungen geschehen. The backfilling of a previously created borehole can also be done with others Devices happen.
