Description

Uppfinnare: E. Tones oeh J. S. Flanders. Inventor: E. Tones oeh J. S. Flanders.

Priorilet begard frdn, den 19 april 1945 (Storbritannien). Priorilet begd frdn, 19 April 1945 (Great Britain).

Foreliggande uppfinning hanfor sig till rOkning med pesticida foreningar, varmed avses foreningar for utrotande av skadliga eller icke onskvarda djur, vOxter och svampar, och isynnerhet till astadkommandet av forenklade eller forbattrade medel far den termiska framstallningen av Talc eller angor av pesticida foreningar, som kunna forAngas vid lãmplig uppphettning. Uppfinningen är sdrskin vardefull for andamdlet att roka med brannbara pesticida fOreningar eller pesticida foreningar som latt sdnderdelas vid overhettfling. Uppfinningen underlattar exempelvis den ekonomiska framstdilningen av en riik, som bestar av en aerosol av den kondenserade fingan av en pesticid forening, som kan utfallas pit begransuingsytorna i ett slutet rum, i vilket Token alstras, for att astadkomma ett tunt skikt av den pesticida foreningen, som fOrblir verksamt langt efter att atmosfdren har blivit fri frail den verksamma roken. The present invention relates to smoking with pesticidal compounds, by which is meant compounds for the eradication of harmful or undesirable animals, plants and fungi, and in particular to the provision of simplified or improved agents for the thermal production of talc or pesticide compounds which can be in case of suitable heating. The invention is particularly valuable for the spirit of smoking with flammable pesticidal compounds or pesticidal compounds which are readily decomposed in the event of overheating. The invention facilitates, for example, the economical production of a rich, which consists of an aerosol of the condensed finger of a pesticidal compound, which can be deposited in the confinement surfaces of a closed space in which Token is generated, to provide a thin layer of the pesticidal compound. which remains active long after the atmosphere has become free frail the active smoke.

Ett exempel pa en pesticid, som kan bilda ett sadant skikt, nar en lamplig rokningsmetod anvandes for forangningen, Or den kraftiga insekticiden a,a-di-(para-klorfeny1)-)3,p,,6- trikloretan. Ett annat ex.empel Or den annu kraftigare insekticiden 7,-hexak1orcyklohexan, som kan pd.foras i form av en rok genom forangning fran varma platar eller genom andra upphettningsmetoder. Det har tidigare beskriTits en metod for rokning an ett slutet rum for bekampning ay skadedjur, vilket bestar i behandling av rummet med en aerosol innehallande hexaklorcyklohexan. An example of a pesticide which can form such a layer when a suitable smoking method is used for the evaporation is the strong insecticide a, a-di- (para-chlorophenyl) -) 3, p ,, 6-trichloroethane. Another example is the even more powerful insecticide 7, hexahlorocyclohexane, which can be introduced in the form of a smoke by evaporation from hot plates or by other heating methods. A method of smoking in a closed room for pest control has previously been described, which consists in treating the room with an aerosol containing hexachlorocyclohexane.

Ett brannbart rokljus, likadant som det vanliga svavelljuset, skulle vara ett mycket lampligt medel for framstallning av rok an en fOrangad pesticid forening, men yid inanga pesticider skulle det icke vara mojligt att framstalla ett ljts, i vilket en pesticid indrages i en laga for att forfingas, emedan pesticiden darvid skulle sonderdelas eller forbrannas under bildning am oanvandbara sdnder delnings- eller forbranningsprodukter, medan vid anvandning ay svavelljuset det aktiva materialet Or den vid svavlets fdrbranning bildade svaveldioxiden. A flammable smoke candle, like the usual sulfur candle, would be a very suitable means of producing smoke from a preferred pesticide compound, but in the case of pesticides it would not be possible to produce a candle in which a pesticide is incorporated into a law to refined, because the pesticide would thereby be probed or incinerated during the formation of unusable subdivision or combustion products, while when used in the sulfur candle the active material Or the sulfur dioxide formed during the sulfur combustion.

Enligt foreliggande uppfinning bestar medlet for termisk framstallning am rok ay den terrniskt forangningsbara pesticida foreningen av en sAkerhetsstubintrad, marl ett eller flera av overdragen av textilgarn omkring den brannbara kdrnan Or overdraget eller impregnerat med pesticiden, och den pesticida foreningen Or foretrd.desvis skyddad frail direkt kontakt med den pulverformiga karnan med alminstone ett fullstandigt skikt ay textiloverdraget. Den anvanda pesticida foreningen kan exempelvis vara en fast forming ay organisk natur, t. ex. hekaklorcyklohexan eller ett klorerat aromatiskt kolvatederivat. Den pulverformiga karnan i sakerhetsstubintrOden omfattar foretradesvis material, sona lainnar gasformiga forbranningsprodukter vid forbranningen, t. ex. en krutblandning, som lampligen icke innehaller svavel. According to the present invention, the means for thermal production consists in the thermally evaporable pesticidal compound of a safety stub row, but one or more of the coatings of textile yarn around the combustible core is coated or impregnated with the pesticide, and the pesticidal compound is preferably protected frail. contact with the powdered karnan with at least one complete layer ay the textile coating. The pesticidal compound used may, for example, be a solid forming an organic nature, e.g. hecachlorocyclohexane or a chlorinated aromatic hydrocarbon derivative. The powdered core of the safety tubing preferably comprises materials, such as gaseous combustion products during combustion, e.g. a powder mixture, which suitably does not contain sulfur.

Expansionen utal av de gasformiga forbranningsprodukterna av den pulverf ormiga karnart och/eller det uppburna textilskiktet i omedelbar kontakt damned genomtranga Vidare det med pesticiden forsedda textiloverdraget och astadkommas stromningar i atmosfaren omedelbart omkring stubinen, varigenom dispergeringen av pesticidangorna beframj as. NOT the safety tube line burns, there is a zone which creeps along the textile cover in front of the active combustion surface of the karnan and which will be at a temperature which is sufficient to evaporate the pesticide. Thus, the conditions are favorable for the evaporation of the pesticide into the atmosphere without effective contact between it and the approaching white-glowing combustion surface of the powdered core. The expansion of the gaseous combustion products of the powdered karnart and / or the supported textile layer in immediate contact dam penetrates. Furthermore, the textile coating provided with the pesticide and flows in the atmosphere are effected immediately around the stub, thereby preventing the dispersion of the pesticide vapors.

Uppfinningen fortydligas av foljande exempel i vilka angivna proeenthalter aro viktsprocent. The invention is illustrated by the following examples in which the stated percentages are by weight.
