Definitions

  • an additional metering pump was installed into the water feed line to the damping solution preparation unit (Technotrans), the metering range of which was 0% to 5%.
  • the damping solution preparation unit was filled with the concentrate composition (1 % by volume added), Wassertop HS 2.48 Spezial damping solution additive (3% by volume added) and 96% by volume of tap water. Metering was monitored via consumption data (water-meter and weighing scales). Conductivity and pH was measured.

Abstract

Dans un processus de modification d'une solution de mouillage d'une machine d'impression offset, un mélange d'un alcool sélectionné parmi un éther monobutyle de mono-, di- ou triéthylène glycol, un éther monobutyle de mono-, di- ou tripropylène glycol, du 2-méthylpentane-2,4- diol (hexylène glycol) et du 2-éthylhexanol (alcool iso-octylique), ou un mélange de ceux-ci, et un ester acétique ou propionique avec l'un quelconque de ces mêmes alcools ou un mélange de tels esters selon un rapport d'environ 40-60 à environ 15-25 parts en volume est introduit dans l'unité de préparation de solution de mouillage de la machine d'impression offset selon une quantité telle que la concentration totale du mélange dans la solution de mouillage du circuit de solution de mouillage est d'environ 0,1 % en volume à environ 1,75 % en volume. L'invention décrit également une composition concentrée ainsi que son utilisation en tant qu'additif dans des solutions de mouillage d'une machine d'impression offset.
