Eine der am vielseitigsten verwendeten Maschinen in der Papierherstellung ist die Langsiebpapiermaschine. Mit dieser Maschine können die üblichen Papierarten hergestellt werden.One of the most versatile machines used in papermaking is the Fourdrinier paper machine. The usual types of paper can be produced with this machine.

Bei schnellaufenden Langsiebpapiermaschinen tritt aber der Nachteil auf, daß der Verschleiß des Maschinensiebes übermäßig groß ist, so daß deren Lebensdauer nur kurz ist.In high-speed Fourdrinier paper machines, however, the disadvantage arises that the machine wire is subject to wear is excessively large so that its life is shortened.

Das Auswechseln des Langsiebes ist eine teure und zeitraubende Arbeit, weil hierbei die Produktion unterbrochen werden muß und ein sorgfältig ausgeführter Vorgang zum Auswechseln nötig ist.Replacing the Fourdrinier is an expensive and time-consuming job because it involves production must be interrupted and a carefully executed replacement process is required.

Es wurde nun gefunden, daß die Maschinensiebe von Langsiebmaschinen eine wesentlich längere Lebensdauer aufweisen, wenn als Schmiermittel eine Lösung ausIt has now been found that the machine screens of Fourdrinier machines are much longer Have service life when used as a lubricant in a solution

worin R ein Ci -i-Alkylrest, Y eine aliphatische Amin enthaltende Gruppe und η = O oder 1 ist, verwendet wird.where R is a Ci -i-alkyl radical, Y is an aliphatic amine-containing group and η = O or 1 is used.

Zusätzlich werden durch dieses Mittel die Korrosion verringert und dadurch die Scheuerfestigkeit sowie die Abflußeigenschaften des Siebes erhöht.In addition, this means reduces the corrosion and thereby the abrasion resistance as well the drainage properties of the screen are increased.

Dieses Mittel braucht nur in einer Menge von 0,005 Pfund pro Tonne Fertigpapier auf die Innenseite des Maschinensiebes aufgesprüht zu werden.This remedy only needs 0.005 pounds per ton of finished paper on the inside of the machine sieve to be sprayed on.

Als Bestandteil werden die Alkalimetallsalze, beispielsweise Natrium-, Kalium-, Cäsium- und Rubidiumsalze, vorzugsweise die Natriumsalze von 2-Mercaptothiazol, 2-Mercaptobenzthiazol, 2-Mercaptobenzimidazol und 2-Mercaptobenzoxazol, vorzugsweise 2-Mercaptobenzthiazol, verwendet.The alkali metal salts, for example sodium, potassium, cesium and rubidium salts, preferably the sodium salts of 2-mercaptothiazole, 2-mercaptobenzothiazole, 2-mercaptobenzimidazole and 2-mercaptobenzoxazole, preferably 2-mercaptobenzothiazole, is used.

Die genannten Verbindungen sind für praktische Zwecke relativ unlöslich in Wasser, aber sie können leicht wasserlöslich gemacht werden, indem sie in ihre Alkalimetallsalze übergeführt werden. Bei den Ammoniumsalzen hingegen treten wegen ihrer Flüchtigkeit Schwierigkeiten auf.The named compounds are relatively insoluble in water for practical purposes, but they can can be made readily soluble in water by converting them into their alkali metal salts. Both Ammonium salts, on the other hand, present difficulties because of their volatility.
