C1genscnattenStability, the flatness and smoothness as well as the electrical conductivity were determined. It is important that the pH value of the BIATbilduS (un S.ebwasser) can be proven to be freely selectable. Process engineering advantages, ζ. The sheet formation is realized at pH values of 6 to 8.

The smoothness reaches about twice the value on the untreated sheet.
Ein ungeleimtes Blatt aus 60% Holzschliff, 20% Fichtensulfitzellstoff und 20% Füllstoff, Flächengewicht 70 g/m2, wird durch eine Lösung nach Beispiel 1 gezogen. Nach dem Abpressen und Trocknen ergibt sich eine volle Schreibleimung nach DIN.

After pressing and drying, the result is full writing glue according to DIN. The ink swim test according to Example 1 achieved at least 270 seconds.
Ein mit 1% Harzleim und 2% Aluminiumsulfat teilweise massegeleimtes Blatt aus 70% Holzschliff und 30% Fichtensulfitzellstoff wird durch die Lösung nach Beispiel 1 gezogen. Während das mit Harzleim teilgeleimte Blatt keine Schreibleimung nach DIN und einen Tjntenschwimmiest nach Beispiel 1 von 20 Sekunden aufwies, war das oberflächengeleimte Blatt nach dem Abpressen und Trocknen voll geleimt nach DIN. Der Tinten-' schwimmtest nach Beispiel 1 war auf 300 Sekunden angestiegen.A sheet made of 70% wood pulp, partially mass-glued with 1% resin glue and 2% aluminum sulphate and 30% spruce sulphite pulp is drawn through the solution according to Example 1. While that with Resin glue partially glued sheet no writing glue according to DIN and a Tintenschwimmiest according to the example 1 of 20 seconds, the surface-sized sheet was after squeezing and Drying fully glued according to DIN. The ink float test of Example 1 was 300 seconds increased.

Als Gegenbeispiel wurden Blätter nach Beispiel I durch folgende Lösungen gezogen, abgepreßt und getrocknet: As a counter-example, leaves according to Example I were drawn through the following solutions, pressed and dried:
a) 20 g/l polystyrol-maleinsaures Natrium in Wasser,a) 20 g / l of polystyrene-maleic acid sodium in water,
b) 20 g/l einer etwa 35 % Paraffin enthaltenden Dispersion in Wasser.b) 20 g / l of a dispersion containing about 35% paraffin in water.
Sowohl nach Verfahren a) wie auch nach b) ergaben sich Blätter, welche nach DIN nicht voll geleimt waren. Der Tintenschwimmtest nach Beispiel 1 überstieg in keinem Fall 60 Sekunden.Both method a) and b) resulted in sheets which were not fully glued according to DIN was. The ink float test of Example 1 never exceeded 60 seconds.
Die Beispiele zeigen, daß die erfindungsgemäße synergistische Kombination zur Oberflächenleimung von Papier und Pappe jeder Zusammensetzung und jedes pH-Wertes sehr gut geeignet ist.The examples show that the synergistic combination according to the invention for surface sizing of paper and cardboard of any composition and any pH value is very suitable.

The classification of the waxes shown in this lite addition of suitable substances to the fiber suspension 45 before sheet formation is summarized as sizing in the mass mineral waxes and their raffinates , Called plants. For a long time, waxes and their raffinates, animal waxes and soaped or emulsified natural resins in combinations of raffinates, semi-synthetic waxes and full nation with aluminum compounds have been used for this purpose. Over the synthetic waxes. Oleic acid is by the time various sizing agents 50 named definitions were not covered and is therefore suggested, so z. B. Tall oil products, hydrocarbons - not under the term "waxes".

In addition to that, in the concentration range from 10 to 50%, cement sizing can be used, for which in the course of time it becomes very difficult. Through this combination, a synergistic process became known, a shear effect was achieved, which, with considerable savings, however, also results in a sizing process through subsequent additions of copolymer (80% and more) a loan application of suitable substances to the upper degree of sizing than that Use surface, the so-called surface sizing. of the copolymer alone. This is about eo over-dieee either in addition to a given, surprisingly, as well as sizing with the possibly reduced in-situ sizing or even for 60th dispersions alone is not possible. One works individually and draws a calibration in addition to the preparation with amounts of 0.1 to 2% of the addition of the sizing effect through additional copolymer and 0.1 to 5% of the wax dispersion, favorable influence on the surface properties based on the entire sizing liquor,
