 von Gips erzielte verbesserte Platten-Feuerwiderstandsfähigkeit bei der Plattenherstellung nach dem Aufwickelverfahren mit gemahlenen Zellstoffasern als Tragfasern. 



   Versuche haben ergeben, dass die Erzielung eines optimalen Ergebnisses in hohem Masse vom richtigen Zellstoffaser-Aufschliessungsgrad (Mahlgrad) im Verhältnis zur betreffenden Zementmenge abhängig ist, welche letztere wieder ziemlich genau auf die Gipsmenge abgestimmt werden muss. 



   Die nachstehende Tabelle enthält einige vergleichende Versuchsergebnisse. Die erste Zeile enthält Ergebnisse, die mit einer Bauplatten-Zusammensetzung nach der DE-AS 2918974 erzielt wurden, während die folgenden Zeilen mit Plattenzusammensetzungen gemäss der Erfindung erreichte Ergebnisse enthalten.

 EMI1.1
 

 <Desc / Clms Page number 2>

 Gypsum achieved improved panel fire resistance in panel manufacturing by the winding process with ground pulp fibers as carrier fibers.



   Experiments have shown that achieving an optimal result depends to a large extent on the correct degree of pulp fiber disintegration (degree of grinding) in relation to the amount of cement in question, the latter again having to be matched to the amount of gypsum used.



   The table below contains some comparative test results. The first line contains results obtained with a building board composition according to DE-AS 2918974, while the following lines contain results achieved with board compositions according to the invention.
