Description
Beim Leimen und Imprägnieren von Papier, Pappe, Gewebe und ähnlichen Stoffen mit Tierleim, Kasein u. dgl. unter · nachträglichem Härten mit Formalin oder Chromsalzeri machen sich unangenehme Nebenerscheinungen bemerkbar. Das Formalin belästigt durch seinen Geruch die Arbeiter, während die Chromsalze der Ware gelbliche Färbung geben.The sizing and impregnation of paper, cardboard, cloth and similar substances with animal glue, casein u. Like. · Under subsequent hardening with formalin or Chromsalzeri to unpleasant side effects become noticeable. The smell of formalin annoys workers, while the chromium salts give the goods a yellowish color.
Es hat sich gezeigt, daß MethylolformamidIt has been shown that methylolformamide
ίο bei genügend langer Einwirkung imstande ist, die Härtung des Tierleims oder.Kaseins eben-, falls mit genügender Sicherheit zu bewirken. Es genügen dabei etwa 2 Prozent Methylolformamid, bezogen auf das Gewicht des trockenen Leimes. Das Methylolformamid kann sowohl dem Leim unmittelbar zugesetzt werden, bevor er auf das Papier usw. aufgestrichen wird, oder man kann den Leim, nachdem er auf dem Papier eingetrocknet ist, mit Methylolformamid behandeln.ίο with a sufficiently long exposure is able to the hardening of the animal glue or casein can also be effected with sufficient certainty. About 2 percent methylolformamide, based on the weight of the, is sufficient dry glue. The methylolformamide can be added directly to the glue before it is painted on the paper etc., or you can use the glue, after it has dried up on the paper treat with methylolformamide.
Wendet man, sei es in der Leimlösung oder nachträglich auf das fertige Papier, größere Mengen Methylolformamid an, z. B. 20 Prozent, bezogen auf das Gewicht des Papiers, so erhält man infolge der hygroskopischen Eigenschäften des Methylolformamids ein außerordentlich geschmeidiges, lederartiges Erzeugnis.If you apply larger ones, be it in the glue solution or afterwards on the finished paper Amounts of methylolformamide, e.g. B. 20 percent, based on the weight of the paper, one obtains due to the hygroscopic properties of methylolformamide is an extraordinarily supple, leather-like product.
