Definitions

  • the present invention relates to aqueous suspensions of zeolite.
  • aqueous suspensions of zeolites present many industrial handling difficulties due to their very particular rheological behavior.
  • suspensions have a dilating behavior and their viscosity is very high. They are therefore difficult to pump, which makes their use, for example their introduction into possibly sprayable detergent mixtures, difficult or even impossible. In addition, these suspensions tend to sediment or gel, which makes them difficult to transport or store. So there is a real problem there.
  • the main object of the invention is therefore a system for obtaining aqueous suspensions of low viscosity zeolite, in particular pumpable.
  • Another object of the invention is a system which also makes it possible to obtain a stable aqueous suspension.
  • the suspensions according to the invention comprise zeolites and they are characterized in that they also comprise a siliconate and / or a siliconate derivative.
  • the aqueous zeolite suspension also comprises at least one stabilizer.
  • siliconates or derivatives has the effect of considerably lowering the viscosity of the zeolite suspensions. It also makes it possible to obtain manipulable suspensions with a higher dry extract, for example of at least 55%. Finally, it has been noted that the siliconates do not influence the exchange capacity of the zeolites.
  • the zeolites used in the context of the present invention include crystalline, amorphous and mixed crystalline-amorphous, natural or synthetic zeolites.
  • finely divided zeolites are used having an average diameter of primary particles of between 0.1 and 10 ⁇ m and, advantageously, between 0.5 and 5 ⁇ m, as well as a theoretical cation exchange power greater than 100 mg of CaCO3 / g of anhydrous product and preferably greater than 200 mg.
