Description
Insekticide und mykocide Imprägnierlösung, für Holz Die vorliegende Erfindung betrifft wäßrige Imprägnierlosungen für Holz und andere organssche Substanzen, um diese vor dem Angriif von Insekten und Fäulnispilzen zu schützen. Die Lösungen haben cinc solche Zusammensetzung, da ß sie nach Einführung in das Material, das imprägniert wird, schwer lösliche Arsenate der Metalle Zn, Cu. Cd oder Al bilden. Die Ausfällung dieser Stoffe wird durch eine gleichzeitig vorhandene Menge Alkalilichronat eingeleitet, wobei gleichzeitig Chromarsetat ausfällt. Die Lösung besteht aus einem wasserlöslichen Salz voll besagten Metallen, Alkaliarsenat, freier Arsensäure und Alkalibichrornat in einem solchen molekularen Mengenverhältnis. daß im wesentlichen lediglich das Arsenat eines der aufgezählten Metalle und Chromarsenat als konservierend wirkende Endprodukte zurickbleiben. Die Zusamnctsetzung der Imprägnierlösung entspricht daher criindunsgemäß folgendem moickularen Mengenverhältnis: 3 ZuSO1: 2Na2 HAsO1:3H3AsO4: Na2Cr2O-Hierbei kö nnen all die Stelle des Zinksulfats andere wasserlösliche Zinksalze oder äquivalente Metgen wasserlöslicher Kupfer-Cadmium- oder Aluminiumsalze treten.Insecticide and mycocide impregnating solution, for wood The present The invention relates to aqueous impregnation solutions for wood and other organic substances, to protect them from attack by insects and rot fungi. The solutions have such a composition that they after introduction into the material that is impregnated, poorly soluble arsenates of the metals Zn, Cu. Form Cd or Al. The precipitation of these substances is caused by a simultaneous amount of alkali dichronate initiated, with chromar acetate precipitating at the same time. The solution consists of one water soluble salt full of said metals, alkali arsenate, free arsenic acid and Alkali bichloromate in such a molecular proportion. that essentially only the arsenate of one of the metals listed and chromium arsenate as a preservative effective end products remain. The composition of the impregnation solution corresponds therefore according to the following molecular ratio: 3 ZuSO1: 2Na2 HAsO1: 3H3AsO4: Na2Cr2O-Here can all the place of the zinc sulfate other water-soluble zinc salts or equivalent amounts of water-soluble copper-cadmium or aluminum salts occur.
In technischem Betrieb sind die Sulfate am zweckmäißigsten auf Grund ihrer Wohlfeilheit und geringen korrodierenden Wirkung.In technical operations, the sulphates are most useful because of the reason their cheapness and low corrosive effect.
Narhdem eine solche Lösung in das Holz eingeführt worden ist. tritt infolge der einsctzetdeii Reduktion des Bichromats etwa folgcnde U-msetzung ein: 3ZnSO4+2Na2HAsO4+3H3AsO4#Na2Cr2O-=3ZnHAsO4+2CrASO4+3Na2SO4#4H2O+3O Bei der Zubereitutg voll Lösungen nach der Erfindung sind besondere Regeln zu lefolgen, tun die Entstclung von Faillangen zu vermeiecn. die sich nur langsam wieder auflösen würden. Solche Fällungen entstehen. Wenn hei der Auflösutg Natriumarsenatlösung finit Metallsalzlösttng in Berührttng kommt, ohne tlat) hinreichend Säitre vorhanden ist. Um dies /a vermeiden, müssen das Natriutnarsenat unl lic Arsensäure @tttelöst werdenl, bevor das gestondert @@@tt@ -Niste Metallsalz zugesetzt wird. Wann dls flichromatt rtugesett ttird. spieit keine Roile.Then such a solution has been introduced into the wood. occurs As a result of the use of reduction of the bichromate the following implementation is used: 3ZnSO4 + 2Na2HAsO4 + 3H3AsO4 # Na2Cr2O- = 3ZnHAsO4 + 2CrASO4 + 3Na2SO4 # 4H2O + 3O for the preparation Full solutions according to the invention are to follow special rules, do the development to avoid catches. that would only slowly dissolve. Such Precipitations arise. If the solution is sodium arsenate finite metal salt solution comes into contact without tlat) there is sufficient acid. To avoid this / a, The sodium arsenate and arsenic acid must be dissolved before this is disrupted @@@ tt @ -Niste metal salt is added. When dls flichromatt rtugesett ttird. spits no roile.

Diese weisen jedoch einen beträchtli ci @1eren i Chrumgehalt im Verhältnis zu den @rigen Bestandteilen auf als die Lösung ge mäß vorliegender Erfindung. Die Im1p@t gnierung wird aller hierdurch u11ö@ig kos@ lieig auf Grund des hohen Verbrauchs vor r Biclrumat. Das Bichromat übt aulßerdem eine in gewisscm Grade schädliche Wirhlng auf das Holz dadurch aus. daß dieses oxyciert wird. Auch aus ciezein Grunle muß demnacl der Gehalt an Bichromat im Verhältnis zui Gehalt an Arsensäure, die ja der un@er mykocidem und insekticidem Gesichtspunkt wirksamste Stoff ist. möglichst miedrig gehaltcn werden.Arsenic acid or alkali metal senate together with bichromate and heavy metal salts @nthaltenle Implementation solutions are already beka @@. These wise however, a considerable content of chromium in relation to the constituents as the solution according to the present invention. Im1p @ t gnierung becomes all as a result u11ö @ ig kos @ lieig due to the high consumption before r Biclrumat. That Bichromate also has a harmful effect on the wood to a certain extent the end. that this is oxidized. Also for reasons of ciezein the content must therefore Bichromate in relation to the content of arsenic acid, which is the un @ er mycocidem and insecticide is the most effective substance. be kept as low as possible.
Demgegenüher wird erfindungsgemäß die geringstmögliche ßichromatmenge verweidet und die größtmögliche Menge schwer löslicher schädlingswidriger Stoffe gebildet.In contrast, according to the invention, the lowest possible amount of dichromate is used grazes and the largest possible amount of poorly soluble harmful substances educated.
