Description
Abbeizlauge zum Entfernen von Öl- und Lackfarbenaustriclien. Die bisher zum Entfernen von Öl- und Lackfarbenanstrichen z. B. von Holz, Eisen, Glas und sonstigen Unterlagen benützten stark ätzenden Abbeizlaugen, zum Beispiel Natronlauge, hatten die Nachteile, dass sie zum Beispiel das Holz aufrauhten, so dass nachheriges Abschleifen nötig war, und dass sie besonders Eichenholz schwarz färbten, Pinsel und Schwämme verbrannten und den Anstrich so erweichten, dass ein Geschmiere entstand, welches mit Terpentin entfernt wer den musste.
Diese Laugen lösten die aus mehreren Schichten zusammengesetzten An striche ungleichmässig; man musste daher den Anstrich bis auf den Holzgrund entfernen. Sie waren ferner für die Haut und für die Kleider schädlich. Für gebeizte Hölzer waren sie unbrauchbar.
Bei Benützung der Gegenstand vorliegen der Erfindung bildenden Lauge werden die genannten Nachteile mehr oder weniger ver mieden. Die Abbeizlauge ist zusammengesetzt aus mit Wasser verdünntem Wasserglas und Salmiakgeist. Beispielsweise besteht das Abbeizmittel aus 100 gr Wasserglas (Lösung von 66%), 100 gr gekochtem Wasser und 10 gr Sal miakgeist.
Die Lauge kann auf den Holz gegenstand finit Pinsel aufgetragen werden, nach einigen Alinuten kann man den An strich schichtenweise mittelst eines Spachtels abnehmen oder mit einem in Wasser ge tränkten Schwamm abwaschen. Man kann dann nach 15-20 Minuten ohne Abschleifen frisch streichen.
Die Abbeizlauge kann auch für das Ent fernen von 01- und Lackanstrichen von Ge genständen aus Eisen und Glas ete. dienen. Auch kann sie für das Entfernen von chemi scher Beize zum Beispiel von Eichenholz dienen.
Diese Lauge macht das Holz nicht schwarz und kann auch für gebeizte Hölzer benützt werden. Die Haut und die Pinsel, sowie die Kleider werden nicht angegriffen. Der A:i- strich wird nicht im ganzen gelöst, bezw. erweicht, sondern schichtweise, so dass der Anstreicher die unterste Schicht von Farbe auf dem Holze lassen und darüber mit fri scher Farbe auftragen kann, wodurch Arbeit und Material gespart werden.
Stripping lye for removing oil and lacquer paint streaks. The previously used to remove oil and varnish paints z. Strongly corrosive stripping lyes, e.g. caustic soda, used for example from wood, iron, glass and other documents, had the disadvantages that they roughened the wood, so that it had to be sanded afterwards, and that they stained oak wood in particular black, brushes and sponges burned and softened the paintwork so that a smear was created that had to be removed with turpentine.
These lyes dissolved the paint, which was composed of several layers, unevenly; you therefore had to remove the paint down to the wooden base. They were also harmful to the skin and clothes. They were useless for stained woods.
When using the lye forming the subject matter of the invention, the disadvantages mentioned are more or less avoided. The stripping solution is made up of water glass diluted with water and ammonia. For example, the paint remover consists of 100 grams of water glass (66% solution), 100 grams of boiled water and 10 grams of salmiakgeist.
The lye can be applied to the wooden object with a finite brush, after a few minutes the paint can be removed in layers using a spatula or washed off with a sponge soaked in water. You can then repaint after 15-20 minutes without sanding.
The stripping lye can also be used to remove oil and varnish from objects made of iron and glass. serve. It can also be used to remove chemical stains from oak, for example.
This lye does not make the wood black and can also be used for stained wood. The skin and the brushes as well as the clothes are not attacked. The A: i stroke is not solved as a whole, resp. softens, but layer by layer, so that the painter can leave the bottom layer of paint on the wood and apply fresh paint over it, saving work and material.
