Definitions

  • the present invention relates to a plant for the dispersion of finely divided solids in highly viscous products.
  • High viscosity, viscous products in which finely divided solids, such as finely divided silica, must be dispersed, are rheologically characterized by extremely non-Newtonian flow properties, meaning that they are pseudoplastic and often have a high yield point. Typically, they are reactive with air, so contact with air must be prevented.
  • the production of such products is possible both in batch mode and in continuous operation. Examples of such products are silicone sealants, insulating and adhesive compounds, toothpaste, special silicones and also all products which are produced with a short mixing time.
  • the continuous production typically takes place in extruders with one, two or more screw shafts, preference being given to using twin-screw extruders for the above-described high-viscosity products.
  • twin-screw extruders has the disadvantage that the energy requirement is high and the investment and operating costs are high. Furthermore, when using twin-screw extruders there is a high minimum throughput, which is why they are only of limited suitability for low production quantities. With lower production volumes and frequent shutdowns, a machine with twin-screw extruders requires a great deal of cleaning.
  • the product is produced with only slight backmixing within the plant, so that simplifying a plug flow or piston flow is present, in which a very high dosing accuracy is required.
  • the product is discharged from the stirred tank with a stamp, since it is not free-flowing and can not be discharged by agitators according to the prior art.
  • the agitator To push out the product from the stirred tank, the agitator must first be removed from the container, resulting in product losses.
  • the cleaning effort and the equipment required for agitator, stamp, etc. are high. It must also be provided a seal of the system against air. Due to the plant size and the driving style, only a very limited throughput can be achieved. As advantages compared to the extruder described above are the lower investment costs and specify the lower dosing accuracy requirements.
