Abstract
Description
Begasungsmittel zur Schädlingsbekämpfung und Verfahren zu seiner Herstellung Zusatz zum Patent .. . (P 19 06 413.2-41) In dem Hauptpatent ist ein Begasungsmittel zur SchädlingsbekSmpfung beschrieben, das durch Einwirkung von Wasser oder Wasserdampf auf Aluminiumphosphid und/oder Magnesiumphosphid und/oder Calciumxyanid als zersetzliche Verbindungen gasförmige insektizide Stoffe entwickelt. Das Begasungsmittel ist dadurch gekennzeichnet, daß die zersetzlichen Verbindungen in feinverteilter Form in einem bei und nach der Ausgasung formbeständigen, der Regelung der Gasentwicklung dienenden Träger aus faserförmigem Material eingebettet sind, das ein wasserfreies Bindemittel enthält. Das Begasungsmittel kann bis zu 70 Gewichtsprozent der zersetzlichen Verbindungen enthalten. Die Teilchen der zersetzlichen Verbindungen können mit einer Umhüllung aus einem Wasser abstoßenden organischen Stoff versehen sein, der gegebenenfalls einen als Treibmittel wirkenden thermisch zersetzbaren Stoff enthält. Das Begasungsaittel kann als Bindemittel Harnstof? oder ein Harnstoffderivat enthalten.Fumigants for pest control and process for their manufacture Addition to the patent ... (P 19 06 413.2-41) In the main patent is a fumigant for pest control, which occurs through the action of water or steam on aluminum phosphide and / or magnesium phosphide and / or calcium xyanide as decomposable Compounds gaseous insecticidal substances developed. The fumigant is thereby characterized in that the decomposable compounds in finely divided form in one dimensionally stable during and after outgassing, used to regulate gas development Carriers made of fibrous material are embedded, which is an anhydrous binder contains. The fumigant can contain up to 70 percent by weight of the decomposing compounds contain. The particles of the decomposable compounds can be coated with a coating be provided from a water-repellent organic substance, which optionally contains a thermally decomposable substance acting as a propellant. The fumigant can urea be used as a binder? or contain a urea derivative.
In einem Zusatz zum Patent ......... (Patentanmeldung P 20 02 655.5 wird eine Ausbildung der Erfindung beschrieben, nach welcher das Begasungsmittel einen Kunststoff, vorzugsweise Polyvinylchlorid, Polyurethan, Polyester, Polystyrol oder ein Gemisch aus zwei oder mehreren dieser Stoffe als Bindemittel enthält. Das Bindemittel kann geschäumt sein und/oder ein Weichmachungsmittel enthalten.In an addition to the patent ......... (patent application P 20 02 655.5 an embodiment of the invention is described, according to which the fumigant a plastic, preferably polyvinyl chloride, polyurethane, polyester, polystyrene or contains a mixture of two or more of these substances as a binder. That Binder can be foamed and / or contain a plasticizer.
Bei der weiteren Ausbildung dieser Erfindung wurde gefunden, daß solche Begasungsmittel besonders geeignet sind, die aus zwei oder mehreren miteinander verbundenen, ein oder zweiseitig beschichteten oder getränkten Flächengebilden wie Platten, Bahnen oder Streifen bestehen.In the further development of this invention it was found that such Fumigants are particularly suitable that consist of two or more with each other connected, one or two-sided coated or impregnated flat structures such as Plates, sheets or strips exist.
Hierbei können eine oder beide äußeren Schichten aus einem keine zersetzlichen Verbindungen enthaltenden Fasermaterial bestehen.Here, one or both of the outer layers of one cannot be decomposable Compounds containing fiber material exist.
Die erfindungsgemäßen Begasungsmittel zeichnen sich durch eine besonders gute Festigkeit aus. Wenn die äußeren Schichten aus einem keine zersetzlichen Verbindungen enthaltenden Fasermatelial bestehen, so wird ein Stäuben oder ein Abrieb der zersetzlichen Verbindungen bei der Handhabung vollständig vermieden.The fumigants according to the invention are distinguished by a special feature good strength. When the outer layers are made of a no decomposable compounds containing fiber material exist, dust or abrasion of the decomposable Completely avoided connections in handling.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung der schichtenförmigen Begasungsmittel. Das Verfahren ist dadurch gekennzeichnet, daß man Platten, Bahnen oder Streifen des faserförmigen Trägermaterials ein- oder zweiseitig mit einer Aufschlämmung der zersetzlichen Verbindung beschichtet oder tränkt und sie dann miteinander verbindet.The invention also relates to a method for producing the layered Fumigants. The method is characterized in that plates, webs or strips of the fibrous carrier material on one or two sides with a slurry the decomposable compound coats or soaks and then bonds them together.
Man kann hierbei auch so vorgehen, daß man Platten, Bahnen oder Streifen des faserförmigen Trägermaterials ein- oder zweiseitig beschichtet oder tränkt, gegebenenfalls zwei oder mehrere dieser Flächengebilde miteinander verbindet und außen auf einer oder beiden Seiten eine Schicht aus Fasermaterial, das keine zersetzlichen Verbindungen enthält, aufbringt.One can also proceed here in such a way that plates, sheets or strips are used the fibrous carrier material is coated or impregnated on one or both sides, optionally connects two or more of these planar structures with one another and outside on one or both sides a layer of non-decomposable fiber material Contains compounds, applies.
