Description

Imprägnierungsverfahren für Holz u. dgl. Es ist bekannt, Pappe dadurch zu imprägnieren, daß man sie erst mit heißer, konzentrierter Alkalilauge durchtränkt und dann in eine heiße, verdünnte Lösung eines löslichen Silikates bringt. Im Gegensatz hierzu besteht das vorliegende Verfahren darin, daß man Holz u. dgl. mit einer Mischung von Wasserglas und Ätzalkali durchtränkt. Dadurch wird erreicht, daß beide Imprägnierungsflüssig keiten in inniger Verbindung gleichmäßig durch alle Schichten des zu imprägnierenden Stoffes verteilt werden und in allen Teilen gemeinsam zur Wirkung kommen. Diese Wirkung besteht u. a. darin; daß das Holz feuersicher und wärmeisolierend wird sowie eine große Härte und Festigkeit gewinnt. Auch verleiht diese Imprägnierung Widerstandsfähigkeit gegen chemische Einflüsse und gegen die zerstörende Einwirkung von Organismen. Nach vorliegendem Verfahren imprägniertes Holz würde sich z. B. zur Herstellung von Gegenständen, bei denen es auf Hitzebeständigkeit ankommt, wie Dichtungsringen für Dampfleitungen oder zur Herstellung von feuersicheren Wänden, zu Verpackungsmaterial und anderen Zwecken eignen, die Anforderungen an hohe Festigkeit bei geringem Gewicht stellen.Impregnation methods for wood and the like. It is known to use cardboard thereby to impregnate so that they are soaked first with hot, concentrated alkali lye and then put in a hot, dilute solution of a soluble silicate. In contrast For this purpose, the present method consists in that wood and the like. With a mixture soaked in water glass and caustic alkali. It is thereby achieved that both impregnation liquid in intimate connection evenly through all layers of the surface to be impregnated Material are distributed and come into effect in all parts together. These Effect exists, among other things. in this; that the wood is fireproof and thermally insulating as well gains great hardness and strength. This impregnation also gives it resistance against chemical influences and against the destructive effects of organisms. To present process impregnated wood would z. B. for the production of objects, where heat resistance is important, such as sealing rings for steam pipes or for the production of fireproof walls, for packaging material and others Suitable for purposes that require high strength and low weight.

Die im Verfahren der Patentschrift 298129 der Klasse 8 beschriebene Mischung von Wasserglas, Kalilauge und Kreide wird wegen der Anwesenheit der Kreide von Holz nicht aufgesaugt, desgleichen nicht Wasserglas ohne Zusatz von Ätzkalilauge.The one described in the Class 8 process of Patent 298129 Mixing water glass, potassium hydroxide and chalk is made because of the presence of the chalk Not soaked up by wood, likewise not water glass without the addition of caustic potash.
