Description

Verfahren zum Leimen von Papier. In -dem Patent 217257 ist ein Mittel zum Leimen von Papier beschrieben, daß aus einem Gemisch von Aluminiumsulfat und Magnesiumsulfat besteht. Magnesiumsulfat allein soll hiernach nicht verwendbar sein. Bei der Herstellung dieses Leimmittels ist der Nachteil zu verzeichnen, daß das hierzu ertorderliche Magnesiu.msulfat in den Fabriken der Kaliindustrie, erst unter großem Wärineaufwanrci aus den i Kieserit gewonnen werden muß. Außerdem üben bekanntlich Sulfatlaugen auf alle Apparaturen eine zerstörende Wirkung aus.Method for gluing paper. In the patent 217257 a means for sizing paper is described that consists of a mixture of aluminum sulfate and magnesium sulfate. Magnesium sulfate alone should not be usable according to this. In the manufacture of this glue, the disadvantage is that the magnesium sulfate required for this in the factories of the potash industry first has to be extracted from the kieserite with a great deal of heat. In addition, sulphate liquors are known to have a destructive effect on all equipment.

Es wurde nun gefunden, daß man statt des Sulfates des Magnesiums auch dessen Chlorid verwenden kann. Das Magnesiuinchlorid ist viel leichter herzustellen als das Sulfat des Magnesiums, und außerdem greift das Chlorid die Apparatur nicht in .:lein Maße an wie das Sulfat.It has now been found that instead of the sulphate of magnesium whose chloride can use. The magnesium chloride is much easier to manufacture than the sulphate of magnesium, and besides, the chloride does not affect the apparatus in.: little like the sulphate.

Es zeigte sich bei den Versuchen, daß Chlormagnesium schon allein eine leimende Wirkung ausübt, die allerdings hochgestellten Ansprüchen für erste Papiere nicht genügen ; dürfte. Eine Mischung von Aluminiumsulfat und Chlormagnesium zeigte dagegen, je nach dem Prozentgehalt des zugefügten Altiminiuinstilfates, eine ganz vorzüglich leimende Wirkung. Beispiel: Bei einem aus i oo kg Harz und 15 kg kalzinierter Soda bestehenden Harzleim verwen-<let man als. Fällungsinittel bei dreifachem Cberschuß der theoretischen Menge etwa 13o kg Chlorinagnesiumlösung von 3o Prozent.It was found in the experiments that chlorine magnesium alone exerts a glueing effect, which, however, is very demanding for the first time Papers are not enough; should. A mixture of aluminum sulfate and magnesium chloride showed, however, depending on the percentage of added altiminiuin stilfate excellent gluing effect. Example: One made of 100 kg of resin and 15 kg Resin glue consisting of calcined soda is used as a. Precipitants three times the theoretical amount about 130 kg chlorine magnesium solution of 3o percent.
