Definitions

  • EP-A-0050036 (PARAMEC CHEMICALS) is intended for threads for cleaning. It does not indicate any parameters that could lead to transposition to sheet metal processing.
  • the projection is carried out under a pressure of the order of 15 to 60 bars and preferably of the order of 15 to 40 bars, at a distance from the upper surface of the sheet as small as possible while allowing efficient operation of the installation.
  • centrifugal pumps which is recommended according to the invention makes it possible to reconcile relatively high pressures with high flow rates resulting in increased efficiency of the process.
  • Impact effect values of the order of 100 to 5000 and preferably 150 to 500 g / cm2 have been found necessary.
  • An installation suitable for implementing the technique of the invention consists of a sheet unwinder 1, an electrolytic installation or quench bath 2, a high pressure degreasing tunnel 3, a rinsing station 4, possible subsequent treatments 5 and a winder 6.
  • the strip bearing the general reference 13 circulates continuously and is continuously subjected to the action of spray jets of a degreasing solution comprising surfactants, originating from spray heads 15 distributed above and below, as well as over the entire width of the strip, for example at a distance of 70 mm from the latter.
  • the alkaline solution is recovered and recycled with possible interposition of filtration equipment (retaining dust and iron fines) and / or regeneration.
  • the equipment described can be associated in appropriate cases with a high density electrolytic degreasing cell, or with other treatment processes, if desired.
  • composition of the solutions used for high pressure spraying is in principle adapted to the operating conditions of operation.
  • alkaline solutions can be used which exert a saponification effect on the esters, optionally with a surfactant. Many of these compositions are known.
