Verfahren zur Leimung von Papier und Pappen. Patentiert im Deutschen Reiche vom 12. Oktober 1910 ab.Process for sizing paper and cardboard. Patented in the German Empire on October 12, 1910.
Bisher erfolgte die Leimung von Papieren und Pappen dadurch, daß Harz mit Soda oder anderen Alkalien gekocht wird, wobei sich das Natron mit einem Teil des Harzes, je nach dem verwendeten Prozentsatz Soda, verbindet, Kohlensäure frei wird und in die Luft entweicht. Die entstandene Harzseife ist wasserlöslich und wird dem zu leimenden Papierstoff in gewissen Mengen zugesetzt.So far, paper and cardboard have been glued by adding resin with soda or other alkalis is boiled, whereby the baking soda with part of the resin, Depending on the percentage of soda used, it combines, carbonates and is released into the Air escapes. The resulting resin soap is water-soluble and is used to glue Paper stock added in certain amounts.
ίο Darauf wird das mit dem Harze gebundene Natron mit einem gewissen Prozentsatz schwefelsaurer Tonerde oder freier Säuren ausgefällt, wobei der gelöste Prozentsatz Harz frei und das Natron an einen Teil der schwefelsauren Tonerde gebunden wird.ίο The baking soda bound with the resin is then placed on it precipitated with a certain percentage of alumina sulfuric acid or free acids, the dissolved percentage being resin free and the baking soda to part of the sulfuric acid Alumina is bound.
Bei dem \^erfahren gemäß der Erfindung soll das teuere Fällungsmittel, die schwefelsaure Tonerde, teilweise durch gasförmige Säuren, insbesondere Kohlensäure in jeder Form, kohlensäurehaltige Gase und schwefligsaure Gase, ersetzt werden.In the experience according to the invention the expensive precipitating agent, sulfuric alumina, is said to be partially replaced by gaseous ones Acids, especially carbonic acid in all forms, carbonated gases and sulphurous acid Gases, to be replaced.
Das an das Natron gebundene Harz wird mit vorgenannten gasförmigen Säuren als freies gelöstes Harz ausgefällt, wobei das Natron, wenn z. B. die Ausfällung mittels Kohlensäure erfolgt, als kohlensaures Natron ausfällt und mit einem entsprechenden Prozentsatz schwefelsaurer Tonerde oder freier Säuren neutralisiert wird. Zur Trennung von HarzThe resin bound to the soda becomes free with the aforementioned gaseous acids dissolved resin precipitated, the soda, if z. B. carbonic acid precipitation occurs when carbonate of soda precipitates and with a corresponding percentage sulfuric alumina or free acids is neutralized. For separating resin
und Natron genügen an Kohlensäure 5 Prozent von der bis jetzt hierzu verwendeten Menge schwefelsaurer Tonerde, und zur Neutralisierung des ausgeschiedenen kohlensauren Natrons genügen 12 Prozent der bis jetzt verwendeten Menge schwefelsaurer Tonerde.and soda suffice in carbonic acid 5 percent of that used up to now for this purpose Amount of sulphate of alumina, and to neutralize the excreted carbonic acid Sodium is sufficient for 12 percent of the amount of sulfuric alumina used up to now.
Da das gebundene Harz durch die Behandlung mit gasförmigen Säuren als reines freies Harz ohne Nebenverbindungen ausgeschieden wird, so kann durch Verwendung von 60 Prozent der bis jetzt notwendigen Harzmenge zur Papierleimung derselbe Effekt, d. h. ein vollständig gut geleimtes Papier erzielt werden.Because the bound resin is treated with gaseous acids as pure free Resin is excreted without secondary compounds, so can by using 60 percent the same effect as the amount of resin required up to now for paper sizing, d. H. a completely well sized paper can be achieved.
Am besten und vorteilhaftesten ist die Verwendung von Kohlensäure, weil diese in jedem Fabrikbetriebe leicht entweder aus der Luft, aus den Rauchgasen von Feuerungen oder sonstigen Prozessen, bei denen sich Kohlensäure bildet, beschafft werden kann.It is best and most beneficial to use carbonated acid because this is in everyone Factory operations easily either from the air, from the flue gases from furnaces or other processes in which carbonic acid is formed can be procured.
